Old Town, New Power

Madrid is an ancient city, no doubt about it. Still, you’ll find forward thinking people, including those operating this hotel near the Plaza Mayor. Look carefully at the roof.

It looks like they have an evacuated tube system for heating water and some photovoltaic panels to make electricity. Good idea. There’s plenty of sunshine in Madrid, might as well use the energy.  I would have liked to talk to someone at the hotel to see how much energy they were saving. Alas, not enough time.
