Pictures above show 10kW alpha prototype MARS on a 350 foot tether. The Magenn Air Rotor System (MARS) is a new generation of wind turbines with cost and performance advantages over existing systems.
MARS is a lighter-than-air tethered wind turbine that rotates about
a horizontal axis in response to wind, generating electrical energy.
This electrical energy is transferred down the tether for
consumption, or to a set of batteries or the power grid. Helium
sustains the Magenn Air Rotor System, which ascends to an altitude
as selected by the operator for the best winds. Its rotation also
generates the "Magnus" effect. This aerodynamic phenomenon provides
additional lift, keeps the MARS device stabilized, positions MARS
within a very controlled and restricted location, and finally,
causes MARS to pull up overhead to maximize altitude rather than
drift downwind on its tether. |
