Yeah it’s a lot easier to eat less calories than it is to burn off that many. 100 calories is like a bag of crisps or so (depends on what) but 100 calories is also about 10 minutes of running which is a lot more work than just eating less. Not that you shouldn’t run but if you’re trying to lose weight it has a much bigger impact to stay at a calorie deficit.

What about tidal?

Well molten salt batteries are a thing, I’m presuming this is to buffer the output of the solar and that the losses were deemed acceptable given the renewable nature of this.

Iirc one of the theoretical ways of generating power with fusion is magnetohydrodynamic generators which use the magnetic field created by the plasma to generate an electrical current directly. Still theoretical though…

Not my garden :) groundhogs don’t exist here
