    This heat wave is absurd in some ways. My 10x5 south-facing balcony is in blazing sunlight. Feels like it could power at least a tiny heat-pump. At 15w/sf that’s 750 watts. Google says a typical home AC is 3500-5000w. So ~15-20%? Are there ad hoc local plug-in solar rigs?

        yes. check out https://store.santansolar.com/  for cheap panels; then you can get a wall-pluggable inverter that will feed it back into your house's grid via a power outlet

        So it's just 2 parts and not even any complex diy work? Is there a meter or something I can use to see how much I'm feeding back in?

        Anything that's plug 'n play consumer will probably be considerably marked up, but if you want to wire it upyourself, will probably have a short payback period.https://twitter.com/mchapiro/status/1296234116803727360 …

        Diablo Canyon nuclear power plant will be shut down due to eco-terrorist "environmentalists". Now electricity costs $0.58/kW in San Luis Obispo county. Companies will run gas generators. 3rd world country problems. I used to think @datarade was being dramatic about California.

        I was fascinated to learn that some modern solar installs combine a heat pump system to cool/extract energy from the back of photovoltaic panels.

        Evaporative cooling is far more efficient.

        Exactly. It's all energy. The question is the wherewithal, the accessibility, the ease, and the financing of switching it from one form to another.
