My technical leisurewear vest has no label and came from a boutique in Barcelona 6 years ago and is olive green not black, navy, light gray, or dark gray. I float above the whole joke. That's what I tell myself to keep wearing it.
I've long thought that a "solar cell" consisting of, say, a parabolic reflector which runs an air compressor directly (no electricity) would be cheap enough to build that its relative lack of efficiency would be made up for by its portability. You can run a lot of a house on compressed air. The air storage tank would be the battery. It's even possible to run a car on compressed air:

I think you found a loophole (which I will soon try to participate in … with anything that Costco sells Kirkland branded)
solar not cheap, you want leccie when you want it.

Thanks for the note, Patrick. Will check this out.
Refrigeration can also in theory be directly run off of compressed air without electricity, because air cools as it expands.
