I believe this area is where the real upside is possible going forward - massive market, natural integration of crypto and trading is obvious. Which projects do you think one should have a look at ?
The biggest problem I have with power based projects is the fact that in order to be useful they would need to be mass-adopted onto grids. I really dont see any large power grid companies deciding to try to use any of these new systems for that, and there really aren't any local opportunities for people to experiment on a small scale.
