Skystream 3.7 is a breakthrough in a new generation of RPAs (Residential Power Appliances) that will change the energy landscape of how homes and small businesses receive electricity. Skystream is the first fully integrated system that produces energy for less than the average cost of electricity in the United States and it produces usable energy in exceptionally low winds. 1
Skystream is available on towers ranging from 33 feet (10.2m) to 110 feet (33.5m).2 tall Its universal inverter will deliver power compatible with any utility grid from 110-240 VAC.3 Skystream will efficiently and quietly provide 40-90% of the energy needs for a home or small business. Any extra energy is fed into the grid spinning the meter backward.4
