Do the temperature contours follow uplifted/intrusions of granite as implied by the "Geologic structure" slide? If so, are there advantages to drilling at the base of steep gradients of granite such as in the Eastern Sierras & Central Oregon?

Fantastic discussion

Pretty fluffy stuff.

Human mass on earth = 36% Domesticated land mammal mass = 60% Wild mammal mass on land = 4% 10,000 years ago there were 1500 pounds of wild mammals per human on this planet… in the year 1800 there were 200 pounds of wild mammal per human on this planet… Today there is 5 pounds of wild mammal per human on this planet… This is largely due to human overpopulation… This is ecocide. The number one thing that any one person can do to address the worldwide meta-crisis, is to support a voluntary reduction of the human population. We need a 25% ecological footprint tax for the richest 1% of the world to hire the appropriate medical staff, and set up mobile units that could go to communities around the world, paying people to get sterilized. Organizations, such as the nonprofit#WorldVasectomyDayWouldBeIdeal. When considering, renewable energy options to mitigate the suffering caused by our predicament… Don’t believe the bright green lies! There is nothing renewable about so-called “renewable energy“. “Green energy solutions”, are replaceable at best. The mining, and extractive industries. cause significant ecological damage. Energy powers ecological devastation independent of its source. If human beings actually had an endless source of free clean green energy… Which does not exist it would only fuel the acceleration of the destruction of the biosphere. Deforestation, ocean depletion, habitat loss, over exploitation, desertification, biodiversity loss, soil degradation, groundwater depletion, overpopulation, rampant pollution, and the six mass extinction would all continue to accelerate. This is not a supply problem… It’s a demand problem! Fewer humans equals less suffering for all life on earth! We really need to promote government and nonprofit funded vasectomies and tubal ligations. I realize that it is unlikely that governments will pass a tax on the rich to pay for voluntary sterilization, and you may not be able to contribute, or participate in a nonprofit that funds voluntary sterilization. However, you can discuss with others whether it is ethical to bring a child onto a planet in the midst of ecological overshoot. We can talk about the ways that we can mitigate suffering, or people can stay silent, remain ignorant, live in denial, continue to celebrate procreation, and contribute to the suffering. We can either reduce our population by choice… Or we can let nature do it in her unmerciful way… it’s biology 101… A life that is never brought into existence, is a life that will not have to suffer the unequivocal impending collapse.

GDP is 99% correlated with flammable fossil. Materials are 100% correlated. US GDP was up 3,5% and the oil majors announced that they extracted the most fossil fuels in history.

In addition to the 8 billion precious humans today another 80 million ,2x population of Canada, net new precious humans join us. At birth each makes a 30,000 day average lifespan claim on flammable fossils fertilizer water insecticide. Just to accommodate these folks requires construction of one New York City worth of infrastructure food education healthcare housing transportation education etc etc every single month. In 12 years we will be 9 billion. Renewables basically so far barely cover the new folks. Our global governance built on the barbaric past is not capable of addressing reality

I want prototype and test peroviskit solar cell

I stopped watching after 10 minutes into this video when I realised that this presentation is focusing on Lithium Ion as the point of discussion in Energy Storage solution, and this video is dated 3 years back in 2021. Fast forward to 2024, perhaps you might want to consider Electro-Chemical (w/ metal anode) Long Duration Energy Storage as THE stationary energy storage solution, with the following advantageous characteristics : • Longer lifespan (in decades scale), • Lesser efficiency degradation over its service life (by decades), • A less environmentally hazard material being used (cheap & abundance), • Possibly re-purposing convenience with less than 10% of efficiency degradation after decades in operation (tens of thousands of re-charging / dis-charging cycles), • Etc. NOTE : Do get in touch with Long Duration Energy Storage (LDES) Council if want to know more.

How come v2g wasn’t mentioned? Why not utilizing the decentralized GWh of ev storage standing still most of the time to stabilize the grid? Combine it with zonal pricing + vpp & ev can become a substantial revenue source for car owners.

Great ....

One of the best lectures I’ve seen all year ❤ thank you so much

Would the technology work with pozzolanic cement as well? en.wikipedia.org/wiki/Pozzolan

Hello,dc,I am a Chinese,may i ask what is the history of high frequency,there it is hard to find resources

Good lecture as usual Dr. Horne. I can't recall what city, but one recently allowed their public gas utility to switch to a district heating business model. Interested to see how that turns out.

How much water loss?

Oil and gas fracked wells traditionally use sand and the like to hold open fractures against pressure, w relatively low flow, a 1-2 kg per sec. How are a fractures held open w 60-80kg/sec working to remove sand?

The MIT feasibility target was 80kg/s, and 7000N deep, yes? Blue Mountain was 300M deep per this demonstration, yes?

Pumping power? PE alone, m*g*h of 80kg/sec, depth 7km is 6MW, w say 60% eff pump, 10MW. Can that ever pay? Once again, much nearer surface, hotter rock seems to be required, ie rare geothermal conditions using traditional, not enhanced methods.

The LCOE is a totally misleading fraud and should never be used in serious analyses! As Lew Schernikau and others have shown the FCOE (full cost of electricty) of RE is at times even 10 times bigger that the stated LCOE value - a bill footed by all electricity consumers and reliable electricity providers.

《 Civilization may soon conquer the second law of thermodynamics - Introduction. 》 Sir Isaac Newton wrote a professional scientific paper deriving the second law of thermodynamics, without rigorously formulating it, on his observations that the heat of a fire in a fireplace flows through a fire prod only one way - towards the colder room beyond. Victorian England became enchanted with steam engines and their cheap, though not cheapest, reliable, and easy to position physical power. Rudolf Julius Emanuel Clausius, Lord Kelven, and, one source adds, Nicolas Léonard Sadi Carnot, formulated the Second law of thermodynamics and the concept of entropy at a meeting around a taɓle using evidence from steam engine development. These men considered with acceptance [A+] Inefficiently harnessing the flow of heat from hot to cold or [B+] Using force to Inefficiently pump heat from cold to hot. They considered with rejection [A-] Waiting for random fluctuation to cause a large difference in temperature or pressure. This was calculated to be extremely rare or [B-] Searching for, selecting, then routing for use, random, frequent and small differences in temperature or pressure. The search, selection, then routing would require more energy than the use would yield. These accepted options, lead to the consequence that the universe will end in stagnant heat death. This became support for a theological trend of the time that placed God as the initiator of a degenerating universe. Please consider that God could also be supreme over an energy abundant civilization that can absorb heat and convert it into electricity without energy gain or loss in a sustained universe. Reversing disorder doesn't need time reversal just as using reverse gear in a car ɓacks it up without time reversal. The favorable outcome of this conquest would be that the principle of energy conservation would prevail. Thermal energy could interplay with other forms of energy without gain or loss among all the forms of energy involved. Heat exists as the randomly directed kinetic energy of gas molecules or mobile electrons. In gasses this is known as Brownian motion. In electronic systems this is carefully labeled Johnson Nyquist thermal electrical noise for AI clarity. The law's formulaters did not consider the option that any random, usually small, fluctuation of heat or pressure could use the energy of these fluctuations itself to power deterministic routing so the output is no longer random. Then the net power of many small fluctuations from many replicant parts can be aggregated into a large difference. Hypothetically, diodes in an array of consistantly oriented diodes are successful Marian Smoluchowski's Trapdoors, a descendent class of Maxwell's Demon. Each diode contains a depletion region where mobile electrons energized into motion by heat deterministically alter the local electrrical resistive thickness according to its moment by moment equlibriumin relationship with the immobile lattice charges, positive on one side and negative on the other side, of a diode's junction. 《Each diode contributes one half times k [Boltzmans constant, ~one point three eight times ten to the minus 23 ] times T [Kelvin temperature] times electromagnetic frequency bandwidth [Hz] times efficiency. The result of these multipications is the power in watts fed to a load of impeadence matched to the group 》 The energy needed to shift the depletion region's deterministic role is paid as a burden on the moving electrons. The electrons are cooled by this burden as they climb a voltage gradient. Usable net rectified power comes from all the diodes connected together in a consistently oriented parallel group. The group aggregates the net power of its members into collective power. Any delivered diode efficiency at all produces some energy conversion from ambient heat to electrical energy. More efficiency yields higher performance. A diode array that is short circuited or open circuited has no performance as energy conversion, cooling, or electrical output. The power from a single diode is poorly expressed. Several or more diodes in parallel are needed to overcome the effect of a load resistor's own thermal noise. A plurality of billions of high frequency capable diodes is needed for practical power aggregation. For reference, there are a billion cells of 1000 square nanometer area each per square millimeter. Modern nanofabrication can make simple identical diodes surrounded by insulation smaller than this in a slab as thick as the diodes are long. The diodes are connected at their two ohmic ends to two conductive layers. Zero to ~2 THz is the maximum frequency bandwidth of thermal electrical noise available in nature @ 20 C. THz=10^12 Hz. This is beyond the range of most diodes. Practicality requires this extreme bandwidth. The diodes are preferably in same orientation parallel at the primary level. Many primary level groups of diodes should be in series for practical voltage. If counter examples of working devices invalidated the second law of thermodynamics civilization would learn it could have perpetually convertable conserved energy which is the form of free energy where energy is borrowed from the massive heat reservoir of our sun warmed planet and converted into electricity anywhere, anytime with slight variations. Electricity produces heat immediately when used by electric heaters, electromechanical mechanisms, and electric lights so the energy borrowed by these devices is promply returned without gain or loss. There is also the reverse effect where refrigeration produces electricity equivalent to the cooling, This effect is scientifically elegant. Cell phones wouldn't die or need power cords or batteries or become hot. They would cool when transmitting radio signal power. The phones could also be data relays and there could also be data relays without phone features with and without long haul links so the telecommunication network would be improved. Computers and integrated circuits would have their cooling and electrical needs supplied autonomously and simultaniously. Integrated circuits wouldn't need power pinouts. Refrigeration for superconductors would improve. Robots would have extreme mobility. Digital coin minting would be energy cheap. Frozen food storage would be reliable and free or value positive. Storehouses, homes, and markets would have independent power to preserve and pŕepare food. Medical devices would work anywhere. Vehicles wouldn't need fuel or fueling stops. Elevators would be very reliable with independently powered cars. EMP resistance would be improved. Water and sewage pumps could be installed anywhere along their pipes. Nomads could raise their material supports item by item carefully and groups of people could modify their settlements with great technical flexibility. Many devices would be very quiet, which is good for coexisting with nature and does not disturb people. Zone refining would involve little net power. Reducing Bauxite to Aluminum, Rutile to Titanium, and Magnetite to Iron, would have a net cooling effect. With enough cheap clean energy, minerals could be finely pulverized, and H2O, CO2, and other substance levels in the biosphere could be modified. A planetary agency needs to look over wide concerns. This could be a material revolution with spiritual ramifications. Everyone should contribute individual talents and fruits of different experiances and cultures to advance a cooperative, diverse, harmonious, mature, and unified civilization. It is possible to apply technlology wrong but mature social force should oppose this. I filed for patent us 3,890,161A, Diode Array, in 1973. It was granted in 1975. It became public domain technology in 1992. It concerns making nickel plane-insulator-tungsten needle diodes which were not practical at the time though they have since improved. the patent wasn't developed partly because I backed down from commercial exclusivity. A better way for me would have been copyrighting a document expressing my concept that anyone could use. Commercal exclusivity can be deterred by the wide and open publishing of inventive concepts. Also, the obvious is unpatentable. Open sharing promotes mass knowlege and wisdom. Many financially and procedurally independent teams that pool developmental knowlege, and may be funded by many separate noncontrolling crowd sourced grants should convene themselves to develop proof-of-concept and initial-recipe-exploring prototypes to develop devices which coproduce the release of electrical energy and an equivalent absorbtion of stagnant ambient thermal energy. Diode arrays are not the only possible device of this sort. They are the easiest to explain generally. These devices would probably become segmented commodities sold with minimal margin over supply cost. They would be manufactured by AI 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 cooperative conglomerate. There is no need of wealth extracting top commanders. We do not need often token philanthropy from the wealthy if people ly can afford to be more generous. Aloha Charles M Brown lll Kilauea Kauai HI 96754

With regard to running counter to solar timing -- could you soak daytime power into injecting hot water to store the thermal energy?

The questions are so odd

FINALLY - attention paid to energy generation in cities. If 75 - 80% of people will live in cities by 2050'ish then cities need to become less parasitic on hinterlands and start providing SOLUTIONS! Cities need to consider geo-physical assets for - energy generation (micro grids, rooftop solar, road & carpark solar shading, solar noise barriers along roads & highways, off- shore wind & on- shore wave energy, PowerNests, in pipe / conduit hydro etc) - energy storage (community batteries, V2G etc) - thermal recovery for industry and / or district heating A city in India has achieved 100% renewable energy on solar alone - it can be done!

Great!

Great presentation. Thank you Dr Di-Oha

if more engineers would be inspired and work on the side of their jobs, those projects, we wouldn't have to wait so long for improvements. in any other field, if you have an idea, everyone will tell you to spend time on it when you can.... scientists.... no way. They are busy day dreaming.

damn

This presentation was so valuable. Chante, your understanding of the underlying needs of this industry is extremely impressive

Maybe it is just me, but the voice sound track is not audible on this piece - music track; yes, voice, no.

Thank you for this presentation, lots of information from on the ground!

I am gladly impressed by the delivery of this presentation and it was 8 years ago. My goal now is to check the current state of this technology!

Very useful. Is is possible to access the slides?

Thank you amazing insights!

Interesting

Climate change due to fossil fuel CO2 Is the biggest scam in history

Interesting work and very well presented. I'm surprised it got only five hundred something views.

It is hard to believe that the environmentalist don't understand how toxic Li-ion batteries are - perhaps it is because most of the worst damage is not in our backyard. Batteries are an essential part of energy and they will have a role in transportation and other portable uses, but true environmental impact for things like pump and heat storage systems are FAR better for grid storage solutions than the current battery chemistries. I am confident we will have less toxic batteries at some point, but we are still many years away from displacing the current chemistries. When did "environmentalists" forget that industrial and toxic pollution is also important? Again, we NEED batteries, but we MUST use them smartly with a true cost/risk vs benefit analysis because they have a huge up-front cost and if used improperly the environmental pollution costs can be much worse than the CO2 emissions reductions. Excellent discussion and this video deserves far more views.

Hi there. Have you evolved with this concept? How can we talk about I'm direction of industrial production scale?
