28:50 You should NOT fully discharge a lithium phosphate (LiFePO4) battery to avoid potential damage. It's recommended to stop discharging at 2.5V per cell to prevent overdischarge, which can harm the battery's internal structure and capacity. While some sources suggest LiFePO4 batteries can handle complete discharges without immediate damage, doing so frequently may reduce their lifespan. For optimal longevity, maintain a discharge range between 20% and 80% of capacity

[@Leo99929]

If you've done your own research, do you have a source you can direct me towards for the 3% of CO2 is from humanity claim? I'm struggling to find a primary source. Everything I can find says 33%.

[@joshuadelisle]

Thank you so much. Cheers J

[@joshuadelisle]

The claim that only about 3-5% of the carbon dioxide (CO₂) in the atmosphere is due to human activities is a point that often comes up in climate discussions, sometimes as an argument against the impact of human-caused (anthropogenic) CO₂ on climate change. Here’s a breakdown of this concept: Natural Sources vs. Anthropogenic Contributions: Naturally occurring processes such as respiration, ocean-atmosphere exchange, and volcanic activity do produce much more CO₂ compared to human emissions in absolute terms. However, these natural processes have long been balanced by natural "sinks" like forests and oceans, which absorb CO₂ from the atmosphere. Human Contribution as a Disruptor of Balance: Although human activities contribute a smaller proportion of the total CO₂ in the atmosphere (around 3-5%), this additional CO₂ disrupts the natural balance. The anthropogenic contribution is not offset by natural sinks, leading to a net increase in atmospheric CO₂ levels, which has been a key driver of global warming. For a detailed scientific perspective, you might refer to sources like: 1. NASA and NOAA (National Oceanic and Atmospheric Administration), which provide insights into how anthropogenic CO₂ contributes to climate change. 2. The Intergovernmental Panel on Climate Change (IPCC) reports, especially the Sixth Assessment Report, which explains how even small proportions of CO₂ emissions can disrupt the natural carbon cycle. 3. Scholarly sources, such as peer-reviewed articles in journals like Nature or Science, address the anthropogenic impact on CO₂ levels more specifically.

[@Leo99929]

​@@joshuadelisle I can't find any reference by NASA, NOAA, or IPCC, saying that anthropogenic CO₂ is 3%-5%. Can you give me a specific source? From reading that it seems like we agree that the earth is in a natural balance, and human activity has destabilised that balance. However I guess we disagree on the mechanism for that change? I feel like it's a pretty open and shut case when you realise that the total CO2 emitted by humanity burning fossil fuels is greater than all plant life on earth. Feel free to Google the mass of CO2 in the atmosphere, amount increased from the industrial revolution, and the mass of all plants on earth to confirm this for yourself. In the last 200 years plants mass would have had to more than double in order to balance that out which would be a drastic change to the balance of the ecosystem. Another way to calculate it is to look at the historic CO2 emissions and add them up. It's about 35 Billion tonnes a year. The total global biomass of plants carbon is 450 billion tonnes. Since CO2 is roughly 33% carbon by weight, that means we emit enough carbon in 38 years to replace all the carbon in all the plants on earth at current rates. We can't double plant biomass every 38 years given forests cover 31% of Earths land area now. We'd run out of space in about 120 years. Then (I'm not 100% sure on this but it seems to make sense, none the less it is just conjecture) it logically follows that once the CO2 emission is reduced because we've run out of fossil fuels or otherwise stopped burning them there isn't enough CO2 to support that plant mass. So it dies back, which releases the captured CO2 in the matter above ground. We might end up in an oscillation that takes a while to dampen out that are faster than species can adapt to, resulting in mess extinctions.

This is probably an off the wall suggestion but have you thought of running the exhaust through a thermal store cylinder instead, they are meant to be filled with hot water not exhaust gases but you can take different feeds off for heating or hot water but they arent cheap Excellent last 10 minutes, agreed with it all!

@@joshuadelisle - Water sounds logical enough, but how about simply setting the exhaust in a metal container filled with an appropriate amount of sand, while running the exhaust ports into and out of the metal cantainer filled with sand(?) The metal container of sand, of course, would/should act as an ultra-cheap and hassle-free passive heat sink. However, I could see using water over sand "if" the application is better suited for taking advantage of the steller heat absorbing qualities/efficiencies of water(!?)

[@Gifftube2020]

I bought a diesel heater as a backup after watching your previous videos 😀 I have been looking at air source heat pumps and follow Heatgeeks own home system his SCOP is 4.64 which is good but obviously his install is top notch. The one thing I would say is that if you had to install a whole new heating system and had the cash you could buy a home battery system from a company like Fogstar, then go to Tomato energy and from 12-6am they sell electric at 5p perkwh. You could store the next days energy and if your heatpump has a SCOP of 4 or more you are looking at 1.25p per kwh (of heat) plus standing charge and the cost of battery, inverter, ASHP so it's not cheap but kind of future proof. Also If you can have 2 meters then you could also install solar and sell it to Octopus at 15p a unit, maybe even rig it to sell tomato 5p energy back to Octopus and beat the B*stds at their own game 🤣I doubt they will allow it but I can dare to dream. Good work sir keep it up 👍

[@Leo99929]

One thing people don't factor in is the amortised cost of the battery and solar panels. Battery is between 7.5p and 20p/kWh delivered over it's life. Solar PV about 9p/kWh. So going off grid would be 9p/kWh if you use it when it's generated, or 16.5p/kWh to 30p/kWh to use it later.

[@Gifftube2020]

@@Leo99929 Yeah good point, it depends on how much it costs all together and if you can do diy. Fogstar have MB31 cells with 8,000 cycles which should last well over 20 years. Solar panels are cheap and if you don't mind doing diy battery and ground mount etc.. you can possibly bring the cost down to around 4-5p. Something will probably break over 20 years so 7p is probably not far off. The ASHP is the game changer if you can get a good scop but that partly depends on the property etc...

I completely agree with you. And I will only add that electric cars are not salvation at all if batteries continue to be produced in this way and we do not have a more developed system for obtaining clean, cheap electricity, after all, they also use energy produced from something (coal, oil, gas, nuclear), and everyone seems to think that they are powered by wishful thinking.

[@johnnodge4327]

EVs are much more efficient than anything with an internal combustion engine, that's a proven fact. As long as the battery or any other of an EVs components are made using renewable energy, then the initial carbon emissions are also low. Obtaining oil and gas is a massively destructive and polluting process, this is before the refining and transportation of it are considered. Electricity on the other hand can be produced with little or no CO2 emissions, and the delivery system is already in place, as it's via the existing electric grid. It dumb to say the EVs alone will solve global warming, but the introduction of efficient mass transportation is a start. There are plenty of other ways to help reduce CO2, like planting millions of trees, but those are often ignored. Looking at the bigger picture is the way to clarity of mind, and not fixate on something you might personally not like, like EVs.

[@joshuadelisle]

I agree that there is a lot of destructive processes that affect the environment in battery manufacturing. Big oil on the other hand is still doing atrocious things to the environment. Both I think can be improved to be low impact and clean. It's the ease of recycle ability that makes me lean towards a combustion engine as it's mainly metal whilst a battery isn't so simple to turn back into a new battery and also the sustainable energy system isn't as sustainable as it appears if you've seen Michael Moore's documentary 'the human planet'. Cheers J

[@tigxxl]

@@johnnodge4327 It's not true that I don't like EVs. I really like their acceleration and larger cargo space, the possibility of using them as an emergency power supply at home or a mobile silent generator for welding machines or other tools. I do up to 100 km on a daily basis and an electric car would be a great solution for me if I had solar panels at home, otherwise it doesn't make financial and ecological sense. Not to mention that I won't earn enough money for such a car for 3 years, saving every penny from my paycheck. But what if the temperature drops to -20 C (and the batteries need to be heated) and I have to drive 200 km somewhere pulling a small, only 700 kg trailer? Of course, another transport option is out of the question because that's why I have my own car available at any time of day or night. And the most important question is how can I fix it myself at home when even manufacturers do not want to fix damaged batteries and this creates a problem of thousands of electric cars in scrap yards because they had a minor accident (Germany/Sweden/Finland/Denmark)? Even in Poland no one wants to touch them, and in Gniezno there are specialists who do miracles with cars after accidents. I can do a major engine overhaul myself, of course by sending the elements for regeneration, but I do not have to take a car with a combustion engine to a special workshop. I do not know how it is in other countries, but access to public chargers does not exist, not to mention that it is 3 times more expensive there than charging at home. My sister lives in Warsaw (the capital of Poland) and has 20 minutes to the nearest charger by tram!!!! The power grid leaves a lot to be desired, only 5 years ago the power line to my house was modernized (3x240v standard in Poland), after more than 10 years of me asking for some repairs and calling the power emergency service because the voltage dropped below 200v. And now imagine what about charging trucks and, for example, electric tractors for farmers? I'm not an engineer, but I have electrical qualifications and I know what expensive solutions and strong power lines are needed for this. And I will mention that Poland is the largest copper miner in the world. I won't mention the power plants themselves because in Poland we still don't have nuclear power, we produce from coal and gas. Supposedly, panels and windmills give something there, but it will get very interesting because many houses are switching to heat pumps and the demand for electricity will increase when it's dark and cold and probably windless. Not to mention that everyone will plug in an electric car in the evening to charge. Read a bit about how electricity production looks like for the entire country, it is impossible to change the amount of electricity produced in a split second (even in an hour). When you look at an individual house, the values ​​are tiny, 6 kW per day. Unless I go to weld something or turn on some other tools. Where I work, 60 kW is used per minute of production of one plastic bumper for a passenger car. And what about industry, construction, emergency services and agriculture or the military? Recently we had a huge flood in Poland in the Silesian region and I wonder how people would charge their cars now since the network is not fully operational yet and that was over a month ago. Why doesn't the military use electric tanks or fighter jets or electric-powered missiles (ion engines are not a myth)? How long would it take a farmer to charge a tractor that was in the field for 16 hours and had to plow 200 hectares per day? Do you know how much energy it takes to literally drag an anchor (plow) driven into the ground? Why aren't the huge ships that transport these wonderful electric cars between continents powered by electricity? Is it because the energy density in lithium batteries is too low?????? And as for CO2, I understand that you don't mean carbon dioxide but other toxic compounds such as nitrates, sulphates, ring benzoates, soot and other dusts? Because everyone keeps trumpeting about CO2 emissions that nature can handle perfectly well (all you had to do was pay attention to photosynthesis in primary school) but no one mentions plastic production, no one is trying to introduce the trend of using a smartphone for 10 years, or a car for 25 because many things can be repaired but why replace them? Passenger planes have to fly for at least 25 years and that's possible because no airline would buy a plane for 3-5 years.

[@Leo99929]

​@@johnnodge4327 the CO2 we have already released into the atmosphere weighs several times more than all of the plants currently on earth combined. 450 Gt of plants vs 1500 Gt of Human released CO2 only since the beginning of the industrial revolution.

If You need new flooring then that experyment says it all. Thermal insulation under, then pipes on top of that (not into it) then cover with sand or concrete. Edges of the floor need to be insulated, the heat exchanger bit bigger. You can add a water heat buffer (100l /200l) because 40C is max for underfloor central heating. Your heater generates too much heat in a short time (to run efficiently). It's like a wood burner using a gasification process, very efficient, eco friendly, but needs buffer for extra water and a big heat exchanger. Best plant for o2 production is hemp. There are loads of types without psychoactive substances. As a side effect, (other than o2 production) it grows extremely fast and is better for paper production. Clothes can be made out of it..... Ford made a car out of it, and it ran on hemp seeds oil 1941. Yet someone is blocking that idea. All the best.

This should be easily achievable if the pipes are laid on some sort of spacers, at half the height of the heat mass.

Regarding your exhaust temp loss, extend the exhaust pipe in doors, like you used to have it, through a water tank similar to the new design. Multiple pipes or a turbulent water flow should help capture the extra heat. Plumb that into your pex and you should see a gain in heat and less wast.

Do your own research. Most of Joshua's numbers were correct (apart form the 3% of CO2 from humans claim, it's actually 33%), but the logic used isn't science. The 0.0012% number is wrong as a consequence of it being 33% rather than 3%, and even if it weren't the small percentage in itself isn't a cogent argument as it depends on the sensitivity of the system to that variable. Example: Changing your body composition by 0.0001% could do nothing if it's CO2 levels, oxygen, or water. But if it's botulinum toxin it would be fatal. The percentage is irrelevant without knowing the sensitivity of the system to that substance. And the evidence for the sensitivity of earth to CO2 levels is overwhelming. Do your own research. Google the graph of atmospheric CO2 levels over time. If you question their validity then check multiple independent sources. Over the life time of people currently alive they have measured a significant increase. Look up the graph of human population vs time. It correlates strongly. Look up the graph of burning fossil fuels vs time. Look up the graph of global average temperature vs time. It's all pretty much the same graph. Correlation isn't causation, but feel free to read up on how we've emitted more CO2 than the weight of all plants on earth. Or how fossil fuels were generated over millennia and burned in decades releasing energy and CO2 at an increasing rate that Earths ecosystem is struggling to keep up with. Evolution takes millennia, not decades.

[@joshuadelisle]

This were I got the 3% from: (chatgbt)The claim that only about 3-5% of the carbon dioxide (CO₂) in the atmosphere is due to human activities is a point that often comes up in climate discussions, sometimes as an argument against the impact of human-caused (anthropogenic) CO₂ on climate change. Here’s a breakdown of this concept: Natural Sources vs. Anthropogenic Contributions: Naturally occurring processes such as respiration, ocean-atmosphere exchange, and volcanic activity do produce much more CO₂ compared to human emissions in absolute terms. However, these natural processes have long been balanced by natural "sinks" like forests and oceans, which absorb CO₂ from the atmosphere. Human Contribution as a Disruptor of Balance: Although human activities contribute a smaller proportion of the total CO₂ in the atmosphere (around 3-5%), this additional CO₂ disrupts the natural balance. The anthropogenic contribution is not offset by natural sinks, leading to a net increase in atmospheric CO₂ levels, which has been a key driver of global warming. For a detailed scientific perspective, you might refer to sources like: 1. NASA and NOAA (National Oceanic and Atmospheric Administration), which provide insights into how anthropogenic CO₂ contributes to climate change. 2. The Intergovernmental Panel on Climate Change (IPCC) reports, especially the Sixth Assessment Report, which explains how even small proportions of CO₂ emissions can disrupt the natural carbon cycle. 3. Scholarly sources, such as peer-reviewed articles in journals like Nature or Science, address the anthropogenic impact on CO₂ levels more specifically.

[@joshuadelisle]

You're still not accounting for the Deforestation when talking about CO2 sequestration and whether measures to reduce CO2 have a far worse economic impact on humanity than what is actually achievable to stop climate change. My stand on adaptation and using what's available compared to high levels of restrictions and pointless taxation still holds regardless. Cheers J

[@Leo99929]

​@@joshuadelisle ChatGPT isn't a reliable source as it "hallucinates" you have to double check it's facts and ask for sources. However when trying to replicate your results it's lead me to find out that human emissions are currently about 35B tonnes CO2 per year, and the earth emits 350B CO2 per year naturally (MIT, Rothman.) which puts humans at 10% of global emissions? And this is outside of the natural balance and so it is accumulating, hence the 33% increase from 1850 due to human activity. That seems to vaguely add up. If you used the carbon component from human emissions as about 33% of the CO2 emissions, but used the global natural CO2 emissions, then that could get you roughly a 3% figure? Maybe someone did that. Carbon vs carbon dioxide by weight? That's the closest I've got to a source for "3%".

The other thing I find supremely annoying is that due to the "energy crisis" fuel prices went up for whatever reason. And our response was to dramatically reduce the amount of energy we use. We turned things off, deliberately bought things to produce cheap heat, stuck solar panels our our homes and batteries in our lofts to use cheaper off-peak energy, worked from home to cut down fuel costs, etc. So what energy companies did was increase the one part of our fuel bills we have no control of - the standing charge. And all we did was shrug and pay it. There is literally no reason for our fuel prices to ever decrease ever again. We've proven we can pay this, and are willing to spend less money on other things to compensate. I wouldn't put it past them to introduce the threat of power interruptions as a way to make us do something beneficial to them. Since either there's plenty of power/resources and no problems at all, this is just being done out of greed. Or the system is severely broken, has been broken for decades, and all the quick fixes and patches we've not noticed are starting to fail.

But when it goes wrong, who pays??? Take Deepwater Horizon for example. Wind and Solar are coming down in price but are not as energy dense as oil. And the one thing you cannot do is reduce the shareholder dividends and CEO bonus.

Hi, another really good video that has raised several interesting points. I have installed one of these diesel heaters in my 10 By 16 foot shed which is built of timber ( wood purchased before prices went daft!) its fully insulated with rockwool. The heater has the exhaust passing through a steel radiator and is piped using 22mm copper, thus extracting as much heat as possible from the exhaust. ( well not all of it by any means! ) There is a fine line as to how much heat one can recover before causing problems with the operation of the heater as you will be fully aware of yourself. The silencer you have used is next to useless as it is basically just an expansion vessel with no baffles at all, several videos on KZbin show that it is difficult to reduce the noise substantially, also is can be dangerouse to reduce the exhaust temperature too far and causing other problems.

You Asked: If CO2 Is Only 0.04% of the Atmosphere, How Does it Drive Global Warming? A: Earth absorbs energy from sunlight, but as the surface warms, it also emits energy in the form of infrared radiation (which we know of as heat) out into space. Water vapor and CO2, however, act like a cap, making it more difficult for Earth to get rid of this energy. Without gases like these to absorb the energy, our planet’s average surface temperature would have been near zero degrees Fahrenheit. About 99 percent of the atmosphere is made of oxygen and nitrogen, which cannot absorb the infrared radiation the Earth emits. Of the remaining 1 percent, the main molecules that can absorb infrared radiation are CO2 and water vapor, because their atoms are able to vibrate in just the right way to absorb the energy that the Earth gives off. After these gases absorb the energy, they emit half of it back to Earth and half of it into space, trapping some of the heat within the atmosphere. This trapping of heat is what we call the greenhouse effect. Because of the greenhouse effect created by these trace gases, the average temperature of the Earth is around 15°C, or 59°F, which allows for life to exist. CO2 makes up only about 0.04% of the atmosphere, and water vapor can vary from 0 to 4%. But while water vapor is the dominant greenhouse gas in our atmosphere, it has *windows* that allow some of the infrared energy to escape without being absorbed. In addition, water vapor is concentrated lower in the atmosphere, whereas CO2 mixes well all the way to about 50 kilometers up. The higher the greenhouse gas, the more effective it is at trapping heat from the Earth’s surface. The burning of fossil fuels affects the concentration of CO2 in the atmosphere. Before the industrial revolution, the amount of CO2 in the atmosphere was about 288 ppm. We have now reached about 414 ppm, so we are on the way to doubling the amount of CO2 in the atmosphere by the end of this century. Scientists say that if CO2 doubles, it could raise the average global temperature of the Earth between two and five degrees Celsius. We are already increasing the amount of energy that bounces back to the Earth. Because of the greenhouse effect, this is causing global warming with its many destructive impacts. Both water vapor and CO2 are responsible for global warming, and once we increase the CO2 in the atmosphere, the oceans warm up, which inevitably triggers an increase in water vapor. But while we have no way to control water vapor, we can control CO2. And because we are increasing the amount of CO2 in the atmosphere by continuing to burn fossil fuels, even in relatively small amounts compared to the entire mass of the atmosphere, we are disturbing the entire heat balance of the planet. For more information on how carbon dioxide traps heat, why water vapor isn’t the culprit, and answers to several other interesting questions, check out this post: How Exactly Does Carbon Dioxide Cause Global Warming? Yochanan Kushnir is a research professor at Lamont-Doherty Earth Observatory, in the Division of Oceans and Climate Physics

[@joshuadelisle]

Thank you but I didn't ask that. it is the % that humans have made compared to natural CO2 that is telling. The crabon isn't the issue its the other factors of heat absorption and lack of water absorption from destruction of ecosystems that are a much bigger issue. cheers J

[@Leo99929]

I'm guessing that you're referencing the claim about 0.0012% of the atmosphere is human produced CO2 which you get from 0.04% CO2 current levels and "3% of that from humanity"? I can't find a primary source for that 3% figure, do you have one? The closest I've got is an Australian news broadcaster and subsequent social media posts referencing that broadcast. It seems this is a typo/decimal place shift of the number you referenced which is a 33% increase in atmospheric CO2 levels since 1850? So it's actually 33% (of current atmospheric CO2 420ppm, or 0.04%. which is 138ppm or 0.014%) from humanity. Not 0.0012%. Also, saying it's a small number doesn't say anything about how much of the effect it has contributed. The dose makes the poison. A 0.00001% change in botulinum content in a person would take them from healthy to death. The sensitivity of a system to an input isn't necessarily linear, meaning that small changes can cause big responses. An example being a hard ball balanced on another hard ball, where a miniscule disturbance might result in it falling much farther. You can't just say "it's a small amount so it's not that". The question we need to answer is "what is the sensitivity of the system to CO2 levels?" and as @cpcnw eluded, the current evidence suggests it's pretty sensitive! Albedo of roads is 0.1 vs forest at 0.15 and 0.4 for concrete. Making a ~5% increase in heat absorption between replacing a forest with a road. and roads account for 0.15% of land area. 0.04% of total area. Not factoring in cloud cover. 0.04%*5% is 0.002% difference in how much heat is absorbed. And that's ignoring the decrease in heat absorbed from concrete vs forest. There are heat domes around urban areas due to this effect and it does contribute to global warming, but not massively. Forests also suck up huge amount of water releasing it through the leaf pores and increase local humidity levels, which decrease local temperatures, but if the local temperature is over a comfortable level then since RH is ~100% people feel uncomfortably hot because they can't loose heat by sweating. They still sweat, it just stays liquid on them as the air capacity for water vapour is already saturated. This humidity condenses in the atmosphere forming clouds that both reflect heat back out of the atmosphere, and act like a blanket reflecting the earths heat back at it. It's a double edged sword. Whether it heats or cools depends on if it's day or night and what the earths local surface is covered with.

The issue isn't the rising temperature. I think that's where the communicators have failed. It's the speed with which it is rising. The earth goes through natural cycles, however the speed with which the heat is rising is not natural. The earth is extremely good at coping with changes over time, but not so great at changes over a short period. Life in general will be fine. Humans on the other hand? We will survive. But not well. Making changes now can help the mass dieoffs that humans will face with inaction. From famine (due to the extremely water hungry crops we currently rely on) and from the increasing severity of natural disasters. And this isn't limited to just one thing. Deforestation, relying on limited resources, and being less than efficient about it in the process. Those are the problems we need to fix. You are absolutely correct, the politicians are corrupt and not going about fixing it in the correct way. But that's not an insurmountable problem. All politics start local. Campaign for change in your local area, and eventually that change will reach the wider world. Giving up is not an option. Failure is not an option. And far too often, people's response to the issue is to gather resources to hunker down and await the storm. To what benefit? Is survival really the goal? Or should it be something more than that? Humans are the *only* species capable of true ecological devistation for personal gain. But similarly, we are the only species capable of fixing ecological devistation for the good of everyone. We both can, and *must* do something about it. Thats why I enjoy your videos. You frequently talk about using resources efficently. But that's why I'd also recommend not using resources like GPT. It's hugely power inefficient. And because its a chatbot, not a search engine, it's frequently incorrect. If you need a resource to do the math for you, I'd recommend wolfram Alpha.

As someone said, can't remember from the top of my head, he who controls the past controls the future. He who controls the present, controls the past.

I didn't notice on your video if you did it or not, but it's better with the pex pipe to install an insert in the end before you insert it into a push fit fitting. It helps to stop failure. I didn't know about those little water heaters, I just ordered one to add underfloor heating to a cold frame. Apparently our wonderful electricity suppliers/the bbc are turning off the signal that switches the old style electricity meter to the cheaper tariff overnight (economy 7) , that would make my current electric underfloor heated cold frame to costly to run. Thanks for the videos, I enjoy your content.

That carbon buildup can be massively reduced if you increase the air into it making it more lean making it burn more efficiently.

[@joshuadelisle]

I think the long exhaust was a factor as it was set on maximum rpm. Having a short exhaust I think has increased the efficiency of the burn but not the recovery. Cheers J

[@DatBoiOrly]

​​@@joshuadelisleI just finished watching the video I think the main issue is heat loss through the exhaust so it would make sense to build a massive water to air heat exchanger that is the shortest run possible to not effect the efficiency of the burn, as you stated in the video an EGR cooler would be best but personally i think you can DIY something better with a two part heat exchanger. Water is funnily enough not a great heat conductor at room temperatures but once it heats up past a certain point it's properties change into a conductor of heat so it'll transfer the heat of the water more efficiently, I would say get rid of the entire hot air portion of the heater & exchange that for a water heating setup then have that plumbed into your DIY EGR heat exchanger for the exhaust which would be a bunch of small pipes that equal if not are greater than the exhaust then have that run outside.

[@TheRealKuif]

Hey Josh, for the heat exchanger, you might want to look into a _plate_ heat exchanger. Those can be expensive, but I'm pretty sure you'll be able to find a second hand one for much less. Looking forward to the next one. Cheers!

Whilst I agree with your points around the environment and policy. The fact about humanity only contributing 3% of the co2 emissions is false. Also although sunspots activity has increased, the total solar irradiance recieved by earth has only changed from about 1360w/msq to 1361w/msq average

What's your source for it not being 3%. I'll check it out. Cheers J

[@Leo99929]

@@joshuadelisle Do you have one saying it is? I can't find it. Not a credible one anyway. Just social media posts. Evidence it isn't 3% is in your video: The hockey stick CO2 levels where it goes exponential at the beginning of the industrial revolution. We're on track to double CO2 levels and are currently at about a 33% increase. My best guess at where the 3% claim came from is that someone mistyped/misremembered 33% as 3%. Humans have released about 3 times more weight of CO2 from burning fossil fuels than the weight of all plants currently on earth. You can't just plant some trees to get rid of that.

This will already have nice efficient coils inside, as that's how a boiler would heat the water. The heated water could then be stored in the cylinder, ready to pump around a radiator system.

You can make your own lithium power station using used lithium cells. They work fine with a “normal” car battery charger but you will need a lithium charge controller. A small motor scooter battery is more than enough to feed the glow plug. A 4 amp battery charger is ample for continuous power of the heater.

[@joshuadelisle]

[@hoggmascall]

I like you but I’m hugely disappointed in your end rant; your position on climate change is badly informed, full of whataboutery and I want to educate your comments. [fwiw I have a PhD in earth sciences, have researched global warming events in earth history and have 30 years experience in the O&G industry] 1. Co2 in the atmosphere - you have to separate natural levels of Co2 from anthropogenic Co2 AND THE RATE IT IS BEING ADDED TO THE NATURAL EARTH SYSTEM; the ‘levels in atmosphere’ argument is facile. The ADDITION rate is the most important. It’s never been added so quickly in the history of life on earth and the only way you can naturally do anything near to this rate is through transient volcanic eruptions; we know from the past transient warming episodes [The event in the Paleocene which made the UK tropical was due to the emplacement of the Iceland plume AND the impact of that plume emplacement on oceanic circulation in the northern Atlantic.] 2. Evidence of a far hotter climate. Contrary to your comments on being in an Ice Age [we are in an Ice House period but..] we are actually in an interglacial [warm] period and you can tell this from sea levels [high], climate [more humid] and ice mass [low] - its all captured in isotope data. We went into an Ice House period about 2.58 million years ago - we even call a geological stage after it - the Quaternary. The causes of greenhouse to ice house transition are multiple and include both earth and planetary inputs : the most likely cause for the last transition 2.58 million years ago include a lot of changes in oceanic circulation patterns due to plate tectonics [the closing of equatorial circulation routes in Panama and Indonesia plus the opening and strengthening of Drakes passage around antarctica] plus CO2 drawdown in the oceans resulting from the uplift and erosion of the Himalayas. By the way, we - Hominids - evolved in Ice House conditions; and records of elephants and rhinos living in UK? Yup that all happened during the ice age. 3. Crude oil has always existed since organic matter has been fossilized; and it has been able to leak to the earths surface and atmosphere; but again it’s the rate of extraction and burning to produce GHG’s thats important. 4. Your conclusion is simply wrong; CO2 should be everyone’s biggest concern as it is and will continue to drive changes in climate and weather patterns as well as precipitate accelerated melting of ice leading to rapid sea level rise [again probably at rates never experienced before even at the end of glacial periods]. Finally - it’s the rate of change resulting from GHG additions that is SO important. On a geological time scale Climate change has happened at slower rates - even rapid events have occurred on the scale of 10’s to 100’s of thousands of years. We are currently experiencing change at the scale of 10 to hundreds of years. It’s never happened and most likely will result in the collapse of ecosystems unable to respond to the weather patterns. Major crop producing areas will fail and seas will inundate over 400 million people resulting in even more global migration. This is all based on scientific studies which are repeatable and whose theories are heavily peer reviewed. Please avoid the conspiracy theory pseudoscience out there, as you can see from my comments above there is a huge amount of human effort in our current understanding and we should respect that work rather than dismiss it.

[@joshuadelisle]

Thank you for sharing your thoughts and experience. I'm not denying the CO2 levels are higher, when I say 'ice age' I don't mean at it's peak but the tail end or 'house' as you put it. Am I right that your response means you believe we can stop climate change by stopping all CO2 production regardless of the economic damage or do you agree with me that even our best attempts to reduce CO2 will not be enough and that adapting to the changing climate is the higher priority? What is your perspective on the 420m hectares of deforestation in relation to the climate data? And what are your thoughts on what other climatologists believe when they say CO2 is a consequence of the planet heating and not the other way round because of the volume of CO2 and methane contained in the ice? I'm open being persuaded and willing to listening. Cheers J

37:50 not sure if you get to this but wouldn’t it make more sense to run the in floor heating through something that isn’t such a great insulator? Like you want something that will absorb the heat and conduct it away. Instead you’ve just run the hot water through an insulated loop! Probably running it directly through concrete or some sort of radiator ( that I’m sure you could cook up ) would work better

[@chir0pter]

Maybe a big water bladder or a flat tank. Something that has both a big heat capacity and conducts heat efficiently. The foam insulation has neither and the aluminum top will probably not work fast enough to pull the heat from the water passing through

[@joshuadelisle]

@@chir0pter you're right but it definitely needs insulation underneath otherwise you lose up to 50% of the energy into the ground and it doesn't come back. However running the pipes through a concrete floor covering as a mass heater is definitely a good idea. Cheers J

Great video much thought provoking. From what I've seen about underfloor heating it seems to work with low temperatures but constantly switched on. Not good for instant heat so any covering like a screed would absorb the heat over time and release gradually. But you probably already know this. Pumping co2 into a green house is of course already done on a commercial basis by sugar beat processors in East Anglia I believe, pumping into tomato producing ventures close by. I think I may be getting one of those heaters soon.

[@Leo99929]

There's more emissions getting your package from the warehouse in the UK to your front door, than from China to the UK. 🤯 There used to be a statistic about the top three container ships on the planet emit more pollution than all cars combined, or something to that effect? But also that they are the most efficient form of transport per kg per km. How?: They're ENORMOUS. Huge emissions per ship, but because each ship hauls so much stuff it turns out it's actually one of the better forms of transport. Better than many planes, for example... And implicitly delivery vans. Also, they used to burn bunker oil which is basically the dirt that's left over when you've extracted all the valuable stuff from crude oil. Since it's international water they can do what they want. However, now they've made that illegal if you're docking in certain ports. But the pollution used to seed clouds which reflected radiation meaning that the measured temp increase was suppressed compared to what it actually was and so it shot up when we switched to cleaner fuel. This problem is incredible complicated. But the oversimplification is that all we need to do is stop burning fossil fuels. Nothing wrong with Coppice (other than the PM2.5 or if it's unsustainably implemented). And realistically the issues are primarily systemic and we are along for the ride. As individuals we can't really move the needle. The pushing of the guilt for it onto the individual consumer is propaganda from the oil industry. I forget which one off the top of my head.
