How far is the ROI?
10k Sats from my solar cells on SunExchange now. My brain is ticking about doing something like this with nuclear power..

You can buy as few or many cells as you want in a project, once it’s funded they go ahead and start paying as soon as it’s online. Details on that link 
Thanks, but I better stack some cheap sats... Renewables are a waste of capital.
Very low and 20 year timeline. Waste of time
