I finally got 2 of the videos of my cousin's and my work on the Vertical Axis Wind Turbine (VAWT) in Costa Rica up.
Some extended information: Each of these turbines is 6 feet tall... the total width of the two turbines is 10' ... it's pretty big and will definitely crank out the wattage! We estimate that the payback period for these simple to build turbines will be 2-3 years.
Each of these was built for about $250 excluding the generator, electronics and batteries. We think and hope that they will last for at least the next 10-20 years with very little maintenance. They are solid steel construction turning in automotive axle supporting ball bearings.
