One thing that confused me about this was the claim that it might selectively advantage solar electricity production. I can understand that the system might work at small scale, making it available for deployment in preference to photovoltaics. But at large scale, surely the efficiency boost that comes from avoiding turbines would be as good for coal-fired and gas-fired generators as for anything else.
