Produce electricity in your own backyard with free, non-polluting, and endless wind power. Skystream 3.7, a breakthrough in Residential Power Appliances (RPA), is changing how homes and small businesses are powered. Developed in collaboration with the U.S. Department of Energy’s National Renewable Energy Laboratory, Skystream is the first all-inclusive system that produces energy for less than the average cost of electricity in the U.S., and it produces usable energy in very low winds. With a guyless tower, Skystream blends in like a neighborhood street lamp. And it operates at a low RPM, so it’s as quiet as wind blowing through trees. Skystream is available on towers of varying heights. Its universal inverter delivers power compatible with any utility grid from 110-240 VAC. Skystream efficiently and quietly provides 40-90% of a home or small business’s energy needs. Any extra energy is fed into the grid, spinning the meter backward.
