VAWT - version #1

This VAWT design that I have is a lift/drag design ... if it were just a drag design, you would have the incoming blades fighting the outgoing blades and you would loose efficiency... in fact, if you remove the baffles and just use a squirrel cage design, under low wind speed, the turbine is not sure which direction it needs to go because of the fighting, and the result is a wind turbine that turns slower than the air speed trying to push it. The baffles create a narrowing that increases the air pressure at the turbine blade. This increased pressure creates more lift and allows the turbine to actually spin faster than the air speed.

This design stems from the basic 'tornado wind tunnel' , 'tornado box' , 'tornado generator chamber' , a few different names as you can see ...

... There is also a famous large tornado generator chamber at Exploratorium museum in San Francisco where children can walk into the device and interrupt the spinning mist vortex.

samdekok72,

Yes, there are plans for a 3-phase 36 magnet pole alternator...Frankly this is a prototype and I'm surprised that it's as responsive as it is. The final design will be out of materials that are better suited to hold up in wet weather conditions. With out spending a great deal of money in the process, I wanted to see for myself how the prototype reacted and was pleasantly surprised.

Nice build. Any plans for an alternator?
