Very well thought article. I didn't know about the activities using the heat to warm homes or grow things. Those sound pretty cool. I would also point out the fact that bitcoin mining can be set up where natural power sources are located. The biggest problem with power is moving it to where the consumers are. It's expensive and it loses a bunch along the way. With mining, companies should be able to go to where the power is. They could set up shop next to a waterfall in the middle of the jungle, for instance. Build a natural power supply from the hydroelectric source nearby and mine without using any dirty electricity and without taking it away from other things that could use it. Great job!!
