While the stability system is good in theory, to prevent people from just building floating factories, building with it quickly turns into an exercise in frustration as you need to place supports for things that aren't there yet, and then hope that you have enough and they're all at the right level otherwise you need to disassemble the top layer and keep going. And when placing rows of machines, if there's a change in elevation you either need to offset as you go, which looks ugly, or disassemble everything and rebuild.

I propose the following: You can place machines/floors without worrying about stability, but they won't be powered/usable until you provide enough stability after the fact. That way you can place what you want where you want it to end up and backfill as needed.

For some reason, the moderation queue is suddenly filled with a bunch of accounts saying things like "the date on the post is years in the future" or "why does it say 06/21/2026?" and stuff like that. Is this confusing to people or is it bots?

Pumped hydro is great, but the geographical requirements mean that it can only be used in limited areas, they take a long time to build, there are environmental concerns, and they can catastrophically fail.

There was a concept for a system called Energy Vault where a large tower would stack and unstack concrete blocks to store and generate power, but there were several mechanical issues with that design and storage capacity was limited by the relatively short height of the tower (compared to the height difference available in pumped hydro).

Could you instead build an electrified cog railway that moved cars with large blocks of concrete up and down an elevation to store and generate power? The rail cars would have electric motors to move the blocks up and could act as generators on the way back down, with storage areas at the top and bottom. You wouldn't have any of the issues of storing and moving a liquid, you could build it practically anywhere with a height difference and ground capable of handling the weight of a rail line, you could build it much higher (Pike's Peak cog railway has an elevation change of 2,300m while the tallest pumped hydro is 630m) and it seems like it would be a lot safer due to the decreased risk of erosion and dam failure.

I did the math with the Taum Sauk pumped hydro station in Missouri (which catastrophically failed and had to be rebuilt), and for an equivalent volume of the upper reservoir (5.37 million cubic meters) and elevation change (260m), it could store more than twice as much energy (7.6GWh vs 3.6GWh currently).

I'm not trying to generate perpetual motion, but rather steal heat energy efficiently from the environment like a heat pump normally does to heat a house.

Either using a heat pump to shift waste heat from the cold end of the Stirling back to the hot end, pulling more heat from the atmosphere/ground and concentrating it in the hot end, and/or pulling more heat out of the cold end and dumping it in the atmosphere/ground. A higher temperature differential would also produce higher efficiencies.

As long as the efficiency of the Stirling engine times the COP of the heat pump is greater than 1 (so, for example, a 25% efficient engine and a COP of over 4), it should be a net positive. Sure, you won't get as much energy out of it overall, but it could run on a much lower temperature gradient.

>Just so you know, when I got in everyone said, oh, eggs, eggs are going through the roof. That was the first. I was in for about four days, and they started screaming at me about eggs. I said that's Biden's problem. I didn't know about eggs, but eggs went up about five times. You did a fantastic job, and we ended up shortly -- in fact, for Easter, they said go out and buy plastic eggs, you can't use real eggs. Well, we bought 200,000 eggs for the White House, for the Easter egg hunt that we have at the White House and there were eggs. We had the price down and now the price is lower than it was before. We did a good job with eggs, but we did a good job with groceries.

Speaking to reporters at a White House press briefing, Leavitt fumed when asked to explain her claims undermining the Epstein documents.

“You said the Epstein documents are a hoax the Democrats are perpetrating against the president,” reporter Maggie Haberman of The New York Times asked. “You said he didn’t sign that check, that he didn’t sign the birthday card that he allegedly signed. So, what is the theory, since these documents came from the Epstein estate? Who is, I guess in your view, faking these documents?”

“I did not say the documents are a hoax,” Leavitt snapped. “I said the entire narrative surrounding Jeffrey Epstein right now that is absorbing many of the liberal cable channels on television is a hoax, that is being perpetuated by opportunistic Democrats—” she ranted.

“What exactly is the hoax?” Haberman pressed. “I’m just trying to understand what’s fake. What’s fake is not the documents?”

“The hoax is the Democrats pretending to care about victims of crime, when they do not care about victims of crime,” Leavitt explained. “When they have done nothing to solve crimes, when they have done nothing to lock up child pedophiles and child rapists across the country, and when they are now using victims as political props, to again, try and smear the president of the United States—” she went on, lost in the spiral of her own semantic spin.

It seems that by contrast, Trump is not even pretending to care about the victims of crime. Last week, the president described calls to release the documents from survivors of Epstein’s abuse as a “Democrat hoax that never ends.”
