One thing I didn't think of is, if this was really cheap to buy AND install it'd work. Solar panels and inverters are currently not economical else they be 100%ish on all roofs. If this cost little, obviously it'd be a break through. But reading the nature article which tries to get into this I'm not convinced it's that cheap or will work better than solar panels.
