Best way to boil water is aim your
solar cooker and put a blackjar inside with your water.
You need a little patience is all.
The issue with the clothes is the cloth is lighter-less in the threads used to make the cloth and more cheaply constructed. If you weighed ten meters of cotton cloth of a certain kind (say sheeting) from 1970 and now, you'd find it has cheapened out and gotten lighter. That fraction means huge
profit PLUS things wear out faster. Forced obsolescence.
IF you are lucky
enough to have a balcony with a southern exposure, at least you can run a small
solar cooker...
As for a regular clothes dryer, wash a load of white teeshirts and clean out the lint trap. That just came off all your clothes, wearing them out further. At least if you hang/line dry or use a clothes rack, you
boost your interior humidity in the winter, and you don't shed all that off your clothes. Line dried stuff doesn't lint.
