Extreme Solar Power
For some time we have had the ability to manufacture huge lenses. We also have computers and software that could make this idea happen. For a prototype, why not construct a large glass lens maybe 12 feet in diameter. Mount it about 30-50 feet above the ground. The base would be round and by computer be able to move round and up and down; tracking the sun 365 days of the year.
The intense heat created by this large magnifying glass could be focused on some hybrid turbine and or steam generator. I imagine it would spit out a lot more heat than windmills. If it worked you could build a real big one.
