Using Vertical Wind Turbines To Harvest The Wind
Caltech researchers say putting lots of vertical-axis wind turbines in a given area will provide more electric generation than very large horizontal turbines you see along the highway (from nc links). There are definitely some limitations to the idea, but it is thought-provoking. Personally, I'd like to find a reasonably priced turbine or solar array which could produce about 100 kilowatt-hours per month. That would cut my grid usage almost in half, which should keep the electric company from getting too mad.

That was kind of my thought. It sounded pretty much like if you covered a wind farm with vertical-axis wind turbines, you could produce more energy than with horizontal turbines because of less turbulence issues. But who's going to put up that many vertical turbines when each one generates very little energy.
