An idea I've had floating around in my head for awhile has been to add solar panels to wind turbines. I hadn't done a lot of research into the idea, so I didn't know if there was some obvious flaw with it or not.
Apparently Bluenergy didn't think so. They have created an aesthetically pleasing wind turbine that includes solar panels on the fins. According to their figures, their invention generates electricity that costs, on average, $.13/kWhr, compared to an average $.23/kWhr for solar energy and $.19/kWhr for wind energy.
