Skip to 3.42. to avoid the video padding. It is basically is just a thermal carbon battery, very similar to the sand battery those in the EU have developed. The hype is not justified AT ALL. Storage efficiency is entirely based on how long you store it for and conversion efficiency to electricity is already circa 37%. Infra red panels with an efficiency of over 40% is hardly a massive leap forward.

40% efficiency…. From heat to electricity…. Does that work out economically?

[@OolTube02]

Depends on how abundant solar energy is going to become and how cheap and plentiful more efficient alternatives are going to get. As for the former, it's going to become very abundant, considering deserts can be covered with arrays as large as agricultural areas. Net power generation will grow by orders of magnitude compared to what we have today in the coming decades. As for the latter, that depends on how cheap resources and manufacturing methods for more efficient forms of storage become. Internal combustion is only 30% efficient, and yet we've been using that, and steam engines, for centuries, because the fuel was so cheap and abundant. Photosynthesis is only 2% efficient and yet we've been using that as a source of energy for billions of years.

Really? I've known for a long time that compared to 2100 A.D. the year 2000 is going to look like the Middle Ages looking back. Even with no technological advancement, just by expanding the already existing technology, our net power production will increase by orders of magnitude from emissions-free sources alone. About 13% of Earth's land area is used for growing crops, and photosynthesis is only 2% efficient. About 14% of the land are hot deserts, and solar PV is 25% efficient. And not nearly as vulnerable to changing temperature and humidity and precipitation patterns. We're at the bottom of an S-curve heading towards a completely different scale now. Climate change may still hit us, but at the other end of this we'll be more independent from weather and climate than we ever were before. And have the energy to do geoengineering on a scale we've never done before -- desalination, irrigation, climate controlled agriculture and habitation. Always keep in mind that climate change would happen eventually anyway, even if we weren't presently causing it. So in order to be able to survive in the long run we better have infrastructure allowing us to adapt to massive changes no matter what the future holds.

The biggest goal is speed in getting this clean transition as quickly as possible. I think it could be possible to pull a lot of heat out of our trillions of tons of garbage we are storing up in land fill , it would slow down the break down process of garbage that naturally happens in nature I think , but our earth is heating up by our tremendous amount of heat coming from the process of garbage process naturally breaking down in our environment. But if we use that heat and regulate the temperature of the speed of the garbage break down and then use that energy in regulating the temperature of garbage speed of break down we can solve two problems at once.

[@Spencergolde]

Thermal energy storage makes sense for storing heating and cooling needs, for hot water, space heating, even industrial process heat. But it is a well proven farce to try to use it for storing electricity. The killer is that, even with a ludicrous 600 C temperature differential, you're only going to recover about half the energy you put into the system, best case scenario in steady state operation. That means if there's two wind turbines generating power, you're throwing away all of the electricity output from one of them. There is no possible economic scenario where you can afford to double your generating capacity to utilize a cheap storage system. You want to drive the thermal differential with a heat pump? Well if you can maintain a high enough COP, and if you're able to recuperate the power cycle without significant pressure drop (which is very difficult at the low temperatures involved) maybe you can squeeze out 80% round trip efficiency, the same as flow batteries but with more mechanical complexity, more maintenance, and occupying 8-10X as much space, even if latent heat with 200kJ/kg capacity storage material were used. It. Is. A bad idea. If you honestly earned a Ph.D in this field without gaining an understanding of thermodynamics or the practical constraints of engineering, than I would suggest asking for a refund.

Enhanced Geothermal using advanced drilling techniques looks promising - maybe even enough to make solar and wind obsolete, especially in areas with poor sun and solar, and maybe areas that don't have many geological faults. Enhanced Geothermal can be dispatchable AND baseload, requiring no storage, with a very small real estate footprint compared to wind or solar. And it's looking like it can be widely used - i.e. not just in areas where geothermal heat comes close to the surface.

Fossil fuel burning cars are 30% efficient. When energy is cheap (like fossil fuels), efficiency doesn’t matter.

That’s why we still drive 30% efficient cars. The operative question for antora is - how much will electricity produced by their batteries cost?

[@1KentKent]

@@flutieflambert All other batteries have better efficiency with Lithium and Pump Hydro being twice as better at 80% efficiency. So you will need twice as many wind turbines or solar panels to get the amount of battery sourced electricity. For example: If your factory needs 1 MW to get it through the night, the solar panels need to produce 1.25 mwh of electricity for the LIFEPO batteries at 80% efficiency. But in this scenario using Heated Carbon, the solar will need to produce 2.5 mwh of electricity at 40% efficiency to reach the 1 mwh. So the cost comparison would need to include added solar panels and the land they stand on. Could there be a scenario that works with cheaper 40% efficiency? Sure. With the limited information that I have, I would presume with industries that have that need for heat and will also use this battery for electricity since they already have it installed.

Heat-to-electricity at low efficiency only makes sense if you can buy the electricity for next to nothing.

The second law of thermodynamics may be false conventional wisdom. Let's face the possibility of breakeven free energy. The second law of thermodynamics was imposed on us during Victorian England's scientific and religious cultural fascination with steam engines. The second law is behind modern refgeration needing electrical energy to compress the refrigerent to force it to release as waste the heat that it has removed from the refrigerator's service interior in the cooling part of the refrigerent's circulation. There is also discarded heat from mechanical friction and electrical resistance. The total released and discarded heat minus the removed heat equals the electrical input balancing this system's energy but this only shows that energy is conserved even if the energy use is unneeded wasteful or harmful. Refrigeration by the principle that energy is conserved should produce electricity instead of consuming it. It makes more sense that refrigerators should yield electricity because energy is widely known to change form with no ultimate path of energy gain or loss being found. Therefore any form of fully recyclable energy can be cycled endlessly in any quantity. In an extreme case senario, full heat recycling, all electric, very isolated underground, undersea, or space communities would be highly survivable with self sufficient EMP resistant LED light banks, automated vertical farms, thaw resistant frozen food storehouses, factories, dwellings, self contained elevators, safe rooms, and horizontal transports. In a flourishing civillization senario, small self sufficient electric or cooling devices of many kinds and styles like lamps, smartphones, hotplates, water heaters, cooler chests, fans, radios, TVs, cameras, security devices, robot test equipment, scales, transaction terminals, wall clocks, open or ciosed for business luminus signs, power hand tools, ditch diggers, pumps, and personal transports, would be available for immediate use incrementally anywhere as people see fit. Some equipment groups could be consolidated on local networks. If a high majority thinks our civilization should geoengineer gigatons or teratons of carbon dioxide out of our environment, instalations using devices that convert ambient heat into electricity can hypothetically be scaled up do it with a choice of comsequences including many beneficial ones. Energy sensible refrigerators that absorb heat and yield electricity would complement computers as computing consumes electricity and yields heat. Computing would be free. Chips could have energy recycling built in. A simple rectifier crystal can, iust short of a replicatable long term demonstration of a powerful prototype, almost certainly filter the random thermal motioren of electrons or discrete positiive charged voids called holes so the electric current flowing in one direction predominates. At low system voltage a filtrate of one polarity predominates only a little but there is always usable electrical power derived from the source, which is Johnson Nyquest thermal electrical noise. This net electrical filtrate can be aggregated in a group of separate diodes in consistent alignment parallel creating widely scalable electrical power. The maximum energy is converted from ambient heat to productive electricity when the electrical load is matched to the array impeadence. Matched impeadence output (watts) is k (Boltźman's constant), one point three eight x 10^ minus 23, times T (temperature Kelvin) times bandwidth (0 Hz to a natural limit ~2 THz @ 290 K) times rectification halving and nanowatt power level rectification efficiency, times the number of diodes in the array. For reference, there are a billion cells of 1000 square nanometer area each per square millimeter, 100 billion per square centimeter. Order is imposed on the random thermal motion of electrons by the structual orderlyness of a diode array made of diodes made within a slab: -----‐------‐----_____-- Out 🔻🔻🔻🔻 ■■■■■■___ + Out All the P type semiconductor anodes abut a metal conductive plane deposited on the top face of the slab with nonrectifying joins; the N type semiconductor cathodes or common cathode abuts the bottom face. As the polarity filtered electrical energy is exported, the amount of thermal energy in the group of diodes decreases. This group cooling will draw heat in from the surrounding ambient heat at a rate depending on the filtering rate and thermal resistance between the group and ambient gas, liquid, or solid warmer than absolute zero. There is always a lot of ambient heat on our planet, more on equatorial dry desert summer days and less on polar desert winter nights. Focusing on explaining the electronic behavior of one composition of simple diode, a near flawless crystal of silicon is modified by implanting a small amount of phosphorus (N type conductivity) on one side from a ohmic contact end to a junction where the additive is suddenly and completely changed to boron (P type conductivity) with minimal disturbance of the crystal lattice. The crystal then continues to another ohmic contact. A region of high electrical resistance forms at the junction in this type of diode when the phosphorous near the ĵunction donates electrons that are free to move elsewhere while leaving phosphorus ions held in the crystal while the boron donates holes which are similalarly free to move. The two types of mobile charges mutually clear each other away near the junction leaving little electrical conductivity. An equlibrium width of this region is settled between the phosphorus, boron, electrons, and holes. Thermal noise is beyond steady state equlibrium. Thermal noise transients, where mobile electrons move from the phosphorus added side to the boron added side ride transient extra conductivity so the forward moving electrons are preferentally filtered into the external circuit. Mobile electrons are units of electric current. They lose their thermal energy of motion and gain electromotive force, another name for voltage, as they transition between the junction and the array electrical tap. Inside the diode, heat is absorbed: outside the diode, to exactly the same extent, an attached electrical circuit is energized. The voltage of a diode array is likely to be small so many similar arrays need to be put in series to build higher voltage. Understanding diodes is one way to become convinced that Johnson Nyquest thermal electrical noise can be rectified and aggregated. Self assembling development teams may find many ways to accomplish this wide mission. Taxonomically there should be many ways ways to convert heat directly into electricity. A practical device may use an array of Au needles in a SiO2 matrix abutting N type GaAs. These were made in the 1970s when registration technology was poor so it was easier to fabricate arrays and select one diode than just make one diode. There are other plausible breeches of the second law of thermodynamics. Hopefully a lot of people will join in expanding the breech. Please share the successes or setbacks of your efforts. These devices would probably become segmented commodities sold with minimal margin over supply cost. They would be manufactured by advanced automation that does not need financial incentive. Applicable best practices would be adopted. Business details would be open public knowledge. Associated people should move as negotiated and freely and honestly talk. Commerce would be a planetary scale unified conglomerate of diverse local cooperatives. There is no need of wealth extracting top commanders.

Yeah why not just grow more dinosaurs and pressurize them into oil to use for cars 🧠🧐

[@OolTube02]

It's actually millions of years old algae gunk from the time of the dinosaurs, not dinosaurs themselves. We could probably turn algae to oil at an industrial scale at some point, but at that point creating synthetic fuels just from air and water and electricity is likely going to be more efficient than anything involving photosynthesis.

[@0ctatr0n]

"What the fossil fuels will just stay in the ground"? Is the interviewer really that dense? Dude, people didn't stop riding horses because we ran out of horses

[@OolTube02]

Making plastics from oil is likely still going to be a thing.

[@0ctatr0n]

@@OolTube02 No it won't, it's lowing the sperm count of literally every male of every species on the planet, it's already dropped male fertility by 50%. We need to switch back to glass steel and wood or perhaps find a way to turn captured carbon into graphene or carbon fibre. Or we'll simply have no one around left to make it due to the sperm counts reaching almost 0

[@drakemia4079]

I think there will be a use for oil and gas but not throwing it into our air like we use it today 30 % efficiency or less is not how to use it . We need to rethink how we use it more safely.

Meh Nuclear still better

[@user-pt1ow8hx5l]

The young guy is speaking with the eyes of a convert. Which is great. Might one add that either natural gas or biogas + hydrogen from windpower is THE balancing act. In Scandinavia. And Ireland. That can provide heat and electricity during winters,... recently other kinds of -electricity-to-heat schemes have been devised,....... The great thing here is the exuberance. And the ideas of how to integrate this into chemical industries and the like.

[@marcus_b1]

This isn't new......at all.

[@alihaider7653]

i dont get it! why are we producing electricity and generating heat from it and then re producing electricity from heat, this process is very ineffective. It doesent make sense to me.

[@JeffBilkins]

Because those things happen at different places and scales.

[@OolTube02]

Because those heat batteries can store much more energy for much longer. The main issue with Li-ion is that you need massive units and still only have power for a few hours. Which is not good enough if your energy supply is intermittent, not only based on the predictable time of day but also on highly unpredictable weather conditions.

[@lucianbakerii7562]

The cute robot carefully selecting a nodule and picking it up with minor disturbance is not true. The actual machine resembles an agricultural combine. It is driven across the sea floor with a wide harvesting scoop. It digs up the everything on or in the sea floor to some shallow depth collecting the nodules and spitting out all the rest into a massive cloud of silty debris. We have no idea how this will impact the ocean. We have some understanding how our continued combustion of carbon based fuel is impacting the ocean. Let's solve that problem without risking the creation of another life threatening manmade issue.

[@OolTube02]

The way I understand it this is supposed to be a different, more expensive, but more delicate approach. I'm just worried that some countries will cut corners and simply go the harvester route.

[@lucianbakerii7562]

@OolTube02 Investors want maximum profits. It's in international water. Who will regulate and enforce? If no enforcement, who will know?

[@GeoCaesar]

@@dertythegrowerwell, even if they are a bot, technically the advice is sound, wool clothing is surprisingly cool, but not as an extra layer in bed. It would be significantly more beneficial to buy wool sheets for their cooling properties. However, the best way to stay cool while sleeping is to sleep in a hammock, airflow below your body stops your mattress from absorbing heat, which is the real main culprit in night sweats and overheating in bed

[@plumberbummer]

The idea of using molten salts for energy storage has been around for decades. Thermal batteries are NOT new.

[@OolTube02]

Molten salt is highly corrosive. Those carbon blocks are not. They're also more conductive than mere sand. It's all about improvement in materials and ramping up actual mass production, not being completely innovative.

[@plumberbummer]

@@OolTube02 In this video they frame themselves as the first people to think of these things, and it's simply not true. That was my point which you must have missed? Sure, they are improving on others people's ideas and technologies, people do that everywhere, but they don't go on to then frame themselves as the inventors of technologies they are merely improving upon. It's like they are claiming they invented smart phones because they came up with a new feature. It's pretty disgusting and very dishonest.

[@JordanGreen-r4h]

Leave the sea floor alone...

[@OolTube02]

Most the deep oceans are desert, with very little life, so there wouldn't be much disruption. Although in the cases of those nodules they may actually be part of an existing ecosystem, so environmental concerns may have merit.
