Helix Wind System, Inexpensive – Reliable – Simple

This is the Helix Wind Turbine, a small-wind, residential scale option that could cut your electricity bills in half, if installed and situated properly.  This 2-kw grid-tie or off-grid system is designed to catch winds at lower speeds.  And it won’t hurt the birds, either.  According to the company’s website, the Helix System is inexpensive, reliable, and simple — it’s a good choice for low wind speed residential and commercial applications. The Savonius turbine based design catches wind from all directions creating smooth powerful torque to spin the electric generator.  Perfect customers live in areas that have amenable small wind zoning and get about 10 mph of wind/cross-winds.  Via EcoGeek.

Also, I’m not sure, but it looks like the Helix can be stacked to generate more power depending on your needs.  This last image is a commercial installation in Barrio Logan, California.

    1. Can it be made with lesser height. Is height a design parameter for the output

    2. Is it limited to usage of wind upto 10 mph. What alterations are needed for winds upto 40 mph and of variable nature.

    I would be happy to recieve any information on this

    The question, of course, is do they work?  Reno Nevada has one up… in a year it has produced 25kWh.  About 0.2kWh/day on a good day, looks like.  For a $10k investment, that’ awfully bad.

    Poor installation?  I dunno, but at least not looking good at that site.
