Vertical Axis Wind Turbine
Posted by: admin
This wind turbine is based on the Lenz II design which measures 4 ft tall X 3 ft in diameter.
The parts can be purchased at http://www.WindGenKits.com
It has a 12 magnet, dual rotor alternater with 9 coils. Each coil is 70 turns.
The wing construction is a steel frame made of laser cut ribs with tubular spars and a trailing edge. The ribs fit into notches on the spars and was welded together. The skin is .030″ aluminum that has been fastened with rivets.
The rotating embly spins on a fixed shaft. Bearings and wing spokes are bolted to the center tri-star carrier plates. The wings can be quickly removed and swapped.
Currently this turbine feeds a small bank of 2 GC-110 wet cell batteries wired in series for a 12V system. AC output is provided by a 1500W inverter.

In his talk “A Pathway for Widespread Utilization of Geothermal Energy–the Roles of Multi-scale Resource and Technology Research and Systems Analysis,” Tester talks about the benefits and challenges of harnessing geothermal energy, and he erts that it is a large resource that complements solar and wind energy and is both carbon free and scalable.
