Summer 2020 I bought a Stirling Cycle engine kit. This is a type of heat engine, and in the case of the kit I assembled, the heat came from a small alcohol lamp.
I went to the local drive-thru strip mall liquor store to buy some Everclear.
I asked the guy behind the counter if they had Everclear. He said, “Making some hand sanitizer, huhn? We’ve got 3 kinds, I don’t think this one is even labeled for human consumption”.
