Efficient sun catcher

The next time someone tries to tell you that renewable energy sources like wind and solar have a fatal flaw - they aren't capable of operating 24/7, you can send them to this page.

Welcome to the future, where we stop making excuses for why something can't be done and just get on with it. Gemasolar produces enough energy to not only generate power during the day, but also store energy in the form of heat in an underground vat of molten salt, which retains its heat for as much as 15 hours. That's long enough to turn water into steam in the middle of the night which in turn spin turbines to generate electricity all night.
