okay so they want to use layer of soil as a sort of seasonal storage. fine; this part works. 1. who’s paying for all these residential heat pumps? 2. this kind of arrangement means a lot of digging and drilling. it takes one (1) nimby to stop it in its tracks and all these earthworks also cost money 3. at this point it’s way simpler and cheaper to just use solar collectors to top up heat reservoir in the summer, as long as heat pumps are paid for. also these same solar collectors would just provide hot water in summer directly
were they advised by rube goldberg?
also, your local university probably has a kind of stability that makes years-decades long commitment worthwhile, unlike some sketchy bloated startup that probably dealt in crypto seven years ago

i heard that a couple of german dcs (owned by universities or other research institutions and therefore indirectly by state) do this, but this kinda depends on district heating grid existing and also puts some limits on thermal side, in simplest variant chips just have to run hotter. not to mention that it’s kinda easier to do when you own the entire thing, long term, and can offload some of the engineering and design effort to some intern student writing masters or doctoral thesis. this works in part because when you switch from coal to gas and have district heating using that waste heat, there’s less waste heat from CCGT of equal power, and it’s all gone when you switch to renewables, so there’s a grid that still needs some heat and dc boiler can fill that gap to a small degree. at the same time dc can’t be the only source of heat because demand is seasonal and dc ideally should run 24/7 and while you can get enough storage for daily variation this won’t be enough and some other source of heat is needed. this is why it makes more sense as a long term government backed project

Yeah there are only so many ways to get it going, you don’t hear about these that don’t figure it out because cops bust them making them look like clowns and nobody wants to get associated with them afterwards
there is also a barrier between step 2 and 3, because sometimes news like that are suppressed. american school shootings get that treatment sometimes, not to mention all the info filtering at facebook and friends. this is why sympathetic media is an important bit to have in advance. there’s also this bit where any serious insurgency needs money and it looks like what they got didn’t work out
that southern police chief was per blogpost Laurie Pritchett and this kind of thinking is also what makes COIN tick. worry not, Hegseth declared it all woke nonsense

eliezer misses that (as used in civil rights era) nonviolence is effectively a sophisticated propaganda strategy that takes existing injustices and violence and uses it to bait opponent into attacking you, all while your own people take photos and show to entire world carefully crafted messaging that appeals to general public conscience. the messaging part is extremely important in this. there’s no fucking way this could work for him because his cause is comprehensible only to those who already buy his cult messaging as ground truth. he’s in just for the moral superiority of being nonviolent. he’s never gonna get it because comprehending it requires touching grass
