We're using the electricity for two purposes. the first is for running the machines. The second is to use the heat generated from the bitcoin machines to fuel the greenhouses. The electric bill will be the same.
The machines produces a great deal of heat Millions of BTUs worth for our operation. This means we can sustain a greenhouse as well. Eventually our greenhouses will be paying for all the electricity from the tomato production.
Resourceful, not dubious, but I can see why you thought that at first glance.
A big question is - can you trick energy prices with tomatoes )
Maybe it could be better to get electricity back with peltier generators, shorter way.
When I see this kind of 'innovation' I'm always thinking: 'if it's so cool why the hell it's not made earlier by someone else?'
At some point you will come up with someone who actually has thought about it first, I also have this process as patent pending.
