To: I got the rope
Bloomberg and various German media (EN) and Spanish media (EN) have revealed that Spain is able to produce solar energy at night, too.

OK whjat happened may have been a scam, but for solar power to work in needs to be from something that gathers energy during the day and released over 24 hours

Solar Updraft Tower

Other advantages:
1. Simple. It just sits there and generates power (The idea of millions of mirrors of solar panels being steered by millions of control systems and millions of motors to track the sun has always seemmed coocoo bananas to me)

2. For this to work they have to be big. No, I mean really BIG

This will be a) cool, and b) annoy the ecomentalists

A collaboraton with the Germans got a solar chimney like that built near Manzanares. in central Spain.

It was proof-of-concept prototype having a 200 meters chimney (just weighting 200 tons), a 250 m diameter collector around it, and a 50 kW generator.

A defect of construction caused it to collapse during a storm in 1989.
