Oh sure, just break a few laws of physics 😂
Discussion
Which law do you think this would break? This was a matter of fact statement.
First law of thermodynamics, unless you have a more interesting way of cascading than I can think of. If you cascade, that means you convert electricity to heat in an ASIC at 100% efficiency, then use the heat as on input to a ~400% efficiency heat pump. How does that get you to >400%? The 100% portion pulls your efficiency down.
You gain already about 100% by switching from air-water to water-water. Then on top you get the heat pump to extract the heat from the water more efficiently by preheating it with the miner. Finally, you can use the cooled water to cool the miner, increasing the efficiency of the miner and reducing the power needed to cool it.
The first law of thermodynamics wouldn’t even allow to reach 100%.
These high numbers are only valid, because the heat pump isn’t a closed system and it purposely draws in energy from the outside.
Go talk to a physicist about your last two notes. I'm sure he will have a good laugh, and you will learn a lot. Win-win.
Or maybe you should 🤷
Explain to me the limits. Why do you say that a heat pump can only get 400%, not 500%?
And then explain why there is groundwater based heat pumps that go up to 500% that you can buy right now.

I won't fall into Brandolini's trap.
