Hello

After looking up specs of some mining machines and putting them up for sale, I noticed most of these machines waste a high amount of energy. Firstly converting AC power to DC at a much lower voltage and cooling power supply that's working hard to keep up. Then running fans to blow head off the heat sinks that are taking heat off the chips that are also working very hard. Next in a lot of cases trying to cool the building that houses all this.

Common sense to me says start with AC in the first place, then use heat recovery to cool the chips down, also under clocking the chips to use less power and run cooler in the first place. I know some people use solar and wind, but  they seem to convert from DC to AC then use a power supply to convert back to DC, seems crazy to me.

With a large power bank (battery), you could cut out the AC bit.

Maybe I've missed something?

I understand this would may not work for the home user, but bigger player's it could and there  would be next no noise. A lot less fans.
