Finally an electric motor for a hang glider(trike). The mosquito and doodlebug versions can't be far behind. They say the thing is quiet.
here are the listed advantages:

Advantages of electric propulsion:

The near silent motor and large, low RPM propeller provide quiet flying enjoyment. No earplugs!
Improved neighbor relations. Possible extra flying sites due to quiet operation.
No handling of smelly gasoline and oil. No soot or dirt.
Sturdy electric motor. No engine maintenance; no disassembly to clean out carbon, no top overhauls, no carburetor adjustments, no expensive major overhauls.
Dependable, no hassle starting, just turn the power dial.
Instant, sure, restart for soaring applications.
Just plug your charger into any 110 outlet to “refuel� our machine. Approx. $0.60 for a full charge. Easily and quickly removable battery packs.
Choose the battery capacity you need.
Small, high discharge rate pack for self launch glider.
Medium pack for light weight; good duration and soarability.
Large pack for longest duration. One to two hours without lift depending on the efficiency of the wing you use.
No vibration. Electric motor with well balanced, slow turning propeller provides vibration free flight.
The closest thing to a magic carpet ride ever attained. Enjoy!
