Re:U.S. corn-based ethanol worse for the climate than gasoline by freeqaz on Tuesday February 15, 2022 @08:50AM (#30346345)
Re: Freezers, yeah, I agree with this. Volume to surface area doesn't scale linearly[0], so you can build something like a giant sphere or cylinder and lose a relatively small amount of energy.

Commercial freezers are also frequently built with vacuum-insulated panels[1] which have very low thermal conductivity.

It's not crazy to build something very large, like a grain silo, to hold dried grain at a low temperature. That seems fairly plausible as a way to reliably "turn off" subsidies over time.

It sort of reminds me of the strategic oil reserve[2] in the US. Similar idea (boring holes in the earth cheaply via using water to etch into giant salt deposits)
