Conceptual design focusing on the ability of a redundant electric propulsion system to provide new capabilities for Vertical Takeoff and Landing aircraft. Specifically utilizing electric motor variable rpm to accomplish a low tipspeed prop-rotor (400 ft/sec tip speed at hover and 200 ft/sec at cruise) to accomplish an order of magnitude reduction in community noise for close proximity operations (30-40 db reduction). The variable rpm capability also achieves a 25% improvement in prop-rotor efficiency through operation at optimal advance ratios.

Introducing the 2010 Fisker Karma
The 2010 Fisker Karma, a plug-in electric hybrid, is the first of four new models built by Quantum.
The car runs on 75 cents per gallon to operate in electric mode, can be charged at home, and will switch to gas mode for longer trips.
Quantum Technologies CEO Alan Niedzwiecki spoke with AlwaysOn's Phyza Jameel last month at the Nordic Green conference.
