Windpod G1 Data

How it works

• Wind turbines operate on a simple principle. The
  energy in the wind turns two or three
  propeller-like blades around a rotor. The rotor
  is connected to the main shaft, which spins a
  generator to create electricity.
• Wind turbines are mounted on a tower to capture
  the most energy. At 100 feet (30 meters) or more
  above ground, they can take advantage of faster
  and less turbulent wind.
• Wind turbines can be used to produce electricity
  for a single home or building, or they can be
  connected to an electricity grid (shown here) for
  more widespread electricity distribution.

How It Works for HelixWind

• As the wind blows the long helical blade scoops
  catch wind from all directions forcing it through
  the turbine. The turbine generator is connected
  directly to your home and as electricity is
  generated your home is powered. If the wind isnt
  blowing your home is powered by the energy grid
  as usual. If the wind is blowing strongly then
  your energy produced can exceed your energy
  consumed and, depending on your local utility,
  your meter can spin backwards rolling back your
  energy bill.

How Does It Work?

• Works in winds as low as 10 mph
• Cupped helical design scoops wind from only one
  side, so the turbine spins freely
• Savonius turbine based design allows for 360
  degrees of usable wind
• Generator is connected directly to stadium for
  useful AC current with the use of an inverter
