  • the federal reserve which you can imagine like a big bank hands out a loan to the government.

    No. Debt goes directly to markets. Federal Reserve QE operations are acts of imagining new money to buy bonds from the market. You are describing QE operations, not debt. Past QE operations have forgone interest on Federal reserve holdings, gifting it to Treasury such that the bonds that Fed holds become interest free. The accounting magic is that when the bond is finally due, the Federal reserve does get paid in order to erase the imaginary money they created to buy the bonds. But a given QE balance sheet level, they just buy a new bond from the market with new imagined money.

    This is 36% MODULE efficiency with expensive cooling. 30% actual year long efficiency without it. Requires dual axis tracking. Seems heavy as its very tall/deep.

    Headline of cost reduction is very unlikely. Especially on a per acre/fairly large area basis. Dual axis tracking requires more spacing than fixed orientation rows, and loses benefits under cloudy conditions. While power at 7am and 5pm is more valuable when competing against high penetration solar, batteries are now more competitive than tracking, and can serve edge of day and night power needs. Tracking solar tends not to be built anymore, due to low cost of panels. The cooling infrastructure is also not as useful as it is on rooftops because the heat capture has useful benefits for homes.

    It is also unclear how this has advantage over parabolic mirror.

    Agri PV is a real use case, where more free land means more land use, even if most of it gets more shade, except around noon.

    Celebrating

    One of the holocaust denial arguments (thanks to Lemmy reposting of grok) is that there was no confirmed written order linking Hitler to it. He might have been just “passively” instigating/inflaming his cabinet/generals into a final solution conference. We still think he celebrated it.

    The Grok solution is to genocide those who celebrate the tiny silver lining in diminishing the chances of (near) future genocides.
