Solar towers in Spain, providing electricity to the city of Seville. Each tower is surrounded by hundreds of mirrors called heliostats. They reflect the sun's light up to a point on the tower. This heats water which runs a turbine.
The heliostats are controlled by computer, so that they adjust the mirrors to catch the sun's rays as the angle changes.
The Spanish government dedicated a large amount of funding to create this solar power system.
When I first saw a picture of this, I thought it looked like science fiction. I guess I'm fascinated by things that look "larger than life". Not only that, but I think it makes great sense to harness natural energy rather than use up all the non-renewable fuel in the world.
How amazing! If only we had enough sunshine in Britain for such a project! (Or if drizzly rain could be harnessed to produce energy....)
ReplyDeleteTrue... they do get a lot of sun in Spain. There should be some way to harness drizzly rain, shouldn't there?
ReplyDeleteWe drove past this amazing thing just a few weeks ago - it was really wow!
