Hello_there

Nuka tempest seemed decent for a diy idea. The shark 5 yr purifier is good for set it and forget it and low cost of ownership. Definitely look up cost of filters before you buy. Housefresh has detailed reviews and you can watch the videos of them testing the device

I don’t know, but finding cheap bikes in the US is hard. Seems like all the shops and used listings only have e bikes for hundreds

Seemed to fuck up one of the pumps I had.

Be careful about refills. If you have some left in the bottle the ratio of soap to water can get off.

Its a feckin weed

There are ‘hybrid’ heat pump mini splits (for air conditioning / cooling) that take both AC and DC input. (See airspool, EG4, and hotspotenergy)

All of these are configured to have dc compressors and AC to DC inverters.

If you have a hybrid system, you either take the conversion losses on the AC or DC input.
For aircon, having the losses on AC to DC conversion makes the most sense - if it’s hot out, it should be bright out and there should be plenty of DC solar output - and topping off with a little AC and taking a loss should be fine.

I don’t think this is the case with water heaters on average - if it’s cold and cloudy or night you’re still going to want hot water. I think it makes sense if you’re in the desert - but most people are not going to be. So don’t think this will be done commercially
