With technology like this, so much for solar power being "intermittent!"
A unique thermosolar power station in southern Spain can shrug off cloudy days: energy stored when the sun shines lets it produce electricity even during the night.
Energy is stored in a vat filled with molten salts at a temperature of more than 500 degrees C (930 F). Those salts are used to produce steam to turn the turbines and produce electricity.
It is the station’s capacity to store energy that makes Gemasolar so different because it allows the plant to transmit power during the night, relying on energy it has accumulated during the day.
Of course, this type of plant requires capital investment, but as the article points out, once "the business has repaid that money to the banks...this station will become a 1,000-euro note printing machine." Not too bad for a power facility that emits no pollutants, contaminates no aquifers, tears down no mountains, and imports no fossil fuels from unstable countries.
