Skystream 3.7 installation

As mentioned on the funding page, the tower height is a cost factor. This for both the tower itself as well as for the foundation required.

The turbine is a downwind design so that the blades of the turbine are downstream from the nacelle, which is inherently better at finding the wind direction than upwind designs. The curved shape of the blade helps make this a very quiet machine. The inverter actually draws about watts to operate the monitoring system. Because of this, the turbine will not generate electricity when the electrical grid to the building is down.

The inverter is UL certified which means that it meets UL standards for islanding protection, frequency synchronization, flicker, and the ability to withstand surges. The alternator includes of 42 sets of powerful rare earth magnets. The motion of the rotor within the stator generates electricity, but there is no transmission or mechanical braking required. The only moving part is the stator hub. The inverter senses the need for braking and uses the repelling action of the magnets to slow the turbine, much like the regenerative brakes on a hybrid vehicle but in reverse.

Once the winds are strong enough to get the turbine up to speed, the inverter keeps the speed of the turbine between and rpm. The blades are constructed from two halves of compression molded fiberglass.

If a number of people 5 within the same area order at the same time we are able to offer additional savings. Due to substantial foundation costs, the overall cost of each windmill may be reduced if multiple sites are excavated and foundations constructed at the same time. Shipping costs may also be reduced if multiple units are shipped together.

We are happy to pass along these savings directly to our customers. So, talk to your neighbors! Prices based on an installation in Maui, Hawaii - prices for other locations will be adjusted accordingly.

Prices do not include sales tax. Prices will be adjusted in the future. Skystream 3. For an interesting insight into wind power issues and how an individual can help in the big picture, see the article here and photos here - Muffy and Jim Floyd from Maine.

With Skystream, homeowners and small business owners now have the power to choose their electricity source. Developed in collaboration with the U. How it works is simple. During periods of strong winds, Skystream can actually produce excess electricity. Depending on your utility, your meter will spin backwards—giving you credit for a later date. Unlike the iPod, the Skystream is very quiet.

Graceful, Yet Powerful With a rated capacity of 2. Its sleek, distinctive swept-wing blades and elegant form make Skystream an attractive addition to any home. With a guyless tower, Skystream blends in like a neighborhood street lamp. And because it operates at a low RPM, Skystream is as quiet as the trees blowing in the wind. Reduce Or Eliminate Your Electricity Bill Skystream is the first wind-powered, grid-connected Residential Power Appliance that produces electricity for less than the retail rate of many utilities.
