The Ledger
Every statement that passed quotation and attribution checks. Mix any filter with any other: certainty 1/5, debate potential 5/5, or both at once.
why aren't all 23 resolved? a statement only gets an assessment when the public record can support or contradict it. opinions and what-ifs never can, and 23 checkable ones are still open, waiting for their date. predictions held up or didn't; assertions are supported or contradicted. on every card: ▮▮▮▮▮ certainty · ▮▮▮▮▮ debate potential. speakers are clickable
Dennett: 2024-2050 copper demand will exceed all historical production combined
“We need more copper between now and twenty-fifty than in the history of human civilization. That includes the Bronze Age.”
Supercool Earth extracts more water from clouds than silver iodide
“And what we bring, as opposed to silver iodide, is that we can target more clouds and essentially bring, get more rain than silver iodide can currently today. So we can target more geographies, more warmer clouds, more seasonalities, and then at that same temp…”
Only one company is delivering a 100MW firm clean project in 2026
“There is one company that's building a hundred megawatt firm clean energy project that's going to be delivered in twenty-twenty-six, and that's a geothermal company.”
O'Donnell: Heat battery grid carbon savings double project-site savings
“And those grid effects of causing more renewables to show up that the heat battery is not using all those megawatt hours mean that the total system carbon savings are approximately twice the savings at the project site.”
Paruri: Tandem PV delivers 30% efficiency boost over silicon, 50% over CdTe
“When you think about our technology compared to silicon, it's like a 30% improvement. When you think about it in compared to cad tell, it's a 50% improvement.”
Sage's subsurface pressure technology can store energy for weeks or months
“So yes, we can literally store the water for weeks, if not months you know, and we would just monitor the pressure depending on the formation permeability. We may have to have water added occasionally to keep the pressure up, but in some formations, like I sai…”
Carneiro: Boston Metal critical metals process cuts carbon footprint by 90%
“Ah, it is at the same time that, that we will have a carbon footprint that at one 10th of the incumbents today.”
Carneiro: Boston Metal produces 2x to 3x more metal per ore volume
“The same amount of ore you can produce twice or three times the amount of metal because our process is more efficient.”
O'Donnell: Heat batteries unlock up to 1.9 times their capacity in renewables
“Jesse Jenkins has, is publishing a paper shortly exploring that. His paper findings really excited us because he found that in looking at systems that he modeled in the east, eastern side of the U.S., for every megawatt of heat batteries that show up in the sy…”
Downing: US electric grid must serve 200 GW of new peak demand
“Well, we have the need to serve 200 gigawatts of new peak demand between now and 2030.”
Supercool Earth's biological seeding targets warmer clouds than silver iodide
“So our biological can target warmer clouds, which are where the ag fields are, so that we can access ag versus any silver iodide-based cloud seeding.”
Cochran: Advanced reactors load follow much faster than historical nuclear
“Many of the technologies, some number of technologies, ours in particular, are able to load follow much more rapidly than historical nuclear.”
Lacey: Fully electric commercial kitchens remain a rarity in America
“What Miles saw is more common in other parts of the world, but still a rarity in America. A fully electric commercial kitchen.”
Canary says burnt conifer forests can hold 80 to 300 dry logs per acre
“You might have 80 to 300 old logs per acre in a burnt out conifer forest, and after a couple years of undergrowth whether it's invasives or natives, like, they get super dried out, you get a lightning strike, boom, you got the next wildfire again”
Canary says removing fire-killed trees is post-fire reforestation's largest cost
“So that was we exited there, but the natural fit there is when we were doing these projects, the number one cost, because these projects were post-fire, was removing the top cost was removing the fire-killed trees.”
Supercool Earth snowmaking protein decomposes within minutes to days
“It's just this protein that when it gets sprayed onto the snow, it freezes and makes ice, and then it gets decomposed. It goes away very quickly within minutes or days in the environment.”
Supercool Earth snowmaking protein is room-temperature stable across seasons
“Whereas our protein, it's a dried protein formulation, and it can, it's stable at room temperature, and it can last season to season.”
Technip Energies completed FEL-1 engineering studies on Graphitic's technology at scale
“And so, Technib completed their FEL-I studies of our technology at both the minimum efficient scale, which is about six tons of hydrogen a day, and also the maximum efficient scale, which is 270 tons of hydrogen a day, which is a world-scale hydrogen plant.”
Lacey: 27% of US Geologist Workforce Will Retire by 2029
“Roughly 27% of the existing workforce in the U.S. Will be retiring by twenty-twenty-nine, and there aren't enough people to take their places.”
Southern California Edison loaded 22,000 regulatory documents into Edison GPT
“They loaded over 22,000 regulatory documents into Edison GPT, like decades of filings, and now internal stakeholders can, you know, if they approach the regulatory team, they need information on a specific filing, a rate case, past information, they can use th…”
Hamilton: Renewables Set to Make Up 80% of New Power Capacity by 2030
“Renewables are set to contribute about 80% of new power capacity by 2030, with PV, solar PV alone, counting for more than half.”
Bowman: South Texas DAC Hub Will Remove 1M Metric Tons Annually
“South Texas, that's the South Texas DAC Hub, being, ah, led by 1.5, a subsidiary of Occidental Petroleum, and the tech provider for this particular project is Carbon Engineering. They will be removing a million metric tons of carbon dioxide annually and storin…”
