I had an idea that I do not remember seeing before and was wondering if any of you have heard or seen anything like this idea:
Concentrating solar has several forms but usually involve mirrors. One of the most effective concentrating solar designs (in terms of cost-effectiveness) is to use an array of controlled flat mirrors that aim their reflection on a tower. Wind power is more effective at higher heights and while you are at it, might as well make the blades longer. I had the idea of putting a concentrating solar receiving point on a large wind mill tower below the shading of the windmill blades. One of the dangers of concentrating solar is a loss of power to the pumps or fans that move the heat away from the point where the sun is concentrating on (and it will get too hot and become damaged). It seems weird to have a back-up power generator at a power generating facility. The wind tower and a bit of energy storage can provide such backup power and the power is produced very close to where it is needed.
A very interesting and useful strategy for combining solar and wind power, both sustainable. It seems like an obvious pairing. Looking forward to reading more posts on this concept.
