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

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.
@Leo99929Күн бұрын
@@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.

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.
@johnnodge43274 күн бұрын
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.
@joshuadelisle4 күн бұрын
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'.

@@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.

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.

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.

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.

Your videos always give me hope. In a world ran by state media, it's nice to see people who can both still think for themselves and prove the system wrong. 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. Regarding your thermal floor panels. the ideal is to "sink" the heat from the source. Maybe some thermal compound between the source (pex) and the floor panels? Best wishes to you and yours!

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.

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.

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.

@@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%".

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. Keep up the great content and the many subjects that you cover.

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. It's built specifically for math, and they've been training it for over a decade. So it's a lot more efficient. Sorry for rambling. Cheers~

There are a variety of sources (done intentionally to get a more accurate reading.) More recent readings come from the growth rings of old forests, those can only go back about 2000 years though. Going back a bit further, coral growth rings, then ice cores can be used to gage temperatures up until 800,000 years ago. Any further than that, they use Benthic cores.

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. It's hard to tell if you're part of the band playing on the Titanic or not until the water's around your neck, but then it's too late.

Now we are drilling in 3km of sea water. it's dangerous / risky and less investors and insurance companies are willing to take the risk. For those that do the pay offs are massive. 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. UK: The richest 350 individuals and families together hold a combined wealth of £795bn - a sum larger than the annual GDP of Poland. Furthermore, the net worth of the twenty richest people in the country has more than doubled in the past decade.

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.

Great segway and points about diet, immunity and cancer (as I tell my teens - everyone has small amounts all the time, immunity keeps it in check). Immunology is a fascinating subject. There is a lot of variation in genetics, but you can improve via diet. Also, similar applies with viruses, we have all the time. When my teen asked me whether they would get a cold from being wet & cold (temp) in our cool summer, I suggested that individually yes, viruses can overwhelm our immune systems when we are exposed to prolonged cool temps (viruses replicate faster below body temp, immune system works best slightly above), but of course exposure to source/seed viruses from others is lower in summer, when the population as a whole is warmer, i.e. there are a lot less incubators.

Thank you. My wife was diagnosed with prenatal diabetes after they took a wrong measurement of our baby.her blood sugar was high because it was around Christmas time which was always an unhealthy time. They immediately prescribed her with medication that had serious side effects and didn't once question her diet. She controlled her blood sugar with a healthy diet and didn't touch the medicine. She was absolutely fine and our son came out the right measurement too. But I remember how insistent they were about it without any thought on re-measuring our baby to check and no advice on diet. That's just one story. Cheers J

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.

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?

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.

I have 2 thoughts. 1, lengthen the exhaust pipe inside, so more heat is captured before being exhausted. How long would require testing. 2, add thermal mass to the radiant floor heating. It may take longer to bring temp up but the thermal mass should retain the heat for longer. Possibly reducing the amount of heat required to maintain a temp once it's reached. I'm sure there's data on this somewhere as radiant floor heating has been around for a bit. There also may be data on which materials perform most efficiently to be used as the thermal mass. I really like these videos. Thanks for sharing your knowledge and experiments.

Truthfully, there is a lot more energy we could take from our atmosphere than we do. For instance a piezoelectric diaphragm that has a vacuum on one side then a vacuum on the other but it is held back by a one way check valve. Just make sure it's shaped to bend back as air rushes past and rebends back into place the diaphragm for Bernoulli's principle to reduce pressure to have it bow out less and setup multiple diaphragms in a row to capture 90% off energy of the air rushing past. Oh, also have it self seal so it maintains vacuum and direction towards a lower pressure for maximal total capture of movement but also making it constantly pump so long as the seals remain for the vacuum and diaphragm. But this introduces vibrations, which can be turned into an acoustic cooler/heater. Neat, huh? But yeah you can make it hollow and have refrigerant get pushed around by diaphragms connected to pump it in a resonance harmonic frequency for Thermo pump (the whistle when heated, when done properly with the right check valve reed valves a pump is created using vibrations) but you did. The diaphragms before but now with extra tube over that. Just on the vacuum side the vacuum will transfer volume as a sonic wave in the metal. Anyways, that gives you vibrational heating while making electricity for the gravitational potential energy converted from air pressure but also absorbs the heat from it needing to rush through and get compressed because of vibrations heading backwards thanks to spring tension of diaphragm relative to the vacuum tension on the other side with the air rushing through. Just need the right clearances, for all of it to do it over the maximal surface area to smallest inner diameter nozzle point to largest surface area. Basically it's an type of hour glass shaped, they call them deval nozzles. Just split them repeatedly into smaller and smaller ones that shape into that, which just means infill is a couple of plates with hole and tube patterns and sequences that makes a fractal 3d repeating inward bound deval nozzle set, which now is easy. Why because offset recessed holes on both sides of the plate with the correct angles done and drilled, sizing too, then you get the deval nozzle fractal repeating set, that's 3d. Then it gets bigger from a ultra small chamber area of check valve piezoelectrics diaphragms. To split it and race it towards the larger area. It's a good generator from just electricity generation, but cools itself with refrigerant, never burns any fuel to do it, easy to make and repair, and be hooked up to another one to transfer energy to the other side which warms everything it gathers on the other side using the same air pump, thermal transfer, the other one is but in reverse. For moving heat somewhere it makes more energy than it takes to run. Because of vacuum energy being the only required true stored energy. It just had to be balanced, which is why spring tension is so nice because it makes it so very much easier to do. So vacuum peristaltic pump that makes heat get moved because of the vacuums inside it what make sure keep wanting to pump it acoustic resonantively and work energy refrigerant, with resistive or no resistive heating added from the generated electricity (because, yup, it does that) or you can use that to just generate electricity for you. Oh right. It scales better and better the bigger you make it, but because multiple smaller ones can be built and made to do it together into a larger center point area for total volume efficiency to then have it exit multiple smaller ones outside, it becomes really really small and non-noticeable. We've had this for decades, truly 1000s of years, the parts at least, not the knowledge put together though lol. Why are we not doing the completely no pollution generator heater/cooler pump like this? 😏

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.
