This thing is incredible. From the BBC, whose article supplies a video tour as well.
From a distance, as we rounded a bend and first caught sight of it, I couldn't believe the strange structure ahead of me was actually real.
A concrete tower - 40 storeys high - stood bathed in intense white light, a totally bizarre image in the depths of the Andalusian countryside.
The tower looked like it was being hosed with giant sprays of water or was somehow being squirted with jets of pale gas. I had trouble working it out.
In fact, as we found out when we got closer, the rays of sunlight reflected by a field of 600 huge mirrors are so intense they illuminate the water vapour and dust hanging in the air.
It is Europe's first commercially operating power station using the Sun's energy this way and at the moment its operator, Solucar, proudly claims that it generates 11 Megawatts (MW) of electricity without emitting a single puff of greenhouse gas. This current figure is enough to power up to 6,000 homes.
But ultimately, the entire plant should generate as much power as is used by the 600,000 people of Seville.
It works by focusing the reflected rays on one location, turning water into steam and then blasting it into turbines to generate power.
Awesome. Going forward, Seville will be known for something other than its great barbers.
Surely you saw that coming...
