The Magenn Power Air Rotor System (MARS) uses helium to float at 400-1000 feet altitude, where the winds have potential to produce double the electrical output over ground based systems. The MARS is portable and generates power as the stationary rotor spins facing the wind.

Prototypes have already flown and a 10-25 kW version is planned for production by 2010. Advantages of the MARS include competitive electricity prices at under 15 cents per kWh. The units are not a threat to birds or bats, and operate extremely quietly. Magenn plans to initially target markets where infrastructure

Imagine an endless supply of all-purpose sanitizer and cleaning solution made by a small electric appliance in your home. Now imagine this cleaning solution is completely effective for all tasks, yet chemical-free and absolutely non-toxic. How much money would you save on cleaning products while
