> There is no such thing as "excess power" for crytomining.
I was thinking the idea seemed to have some validity.. For ex: storage of solar/wind-powered is critical and the current inefficiencies and batteries rely on lithium and alternatives are still in research.(http://worrydream.com/ClimateChange/#moving-storage) ..
so in theory there's a system that can be built around the excess energy(of renewable systems) + crypto mining as a incentive for taking up renewable energy setups.(Of course this cannot convert the mined stuff back to energy so it's a one-way stuff at best and has it's own cons and pros).
