Have to look into vertical turbines for our area.  We’ll have calm winds for weeks on end, then we’ll have gusts up to 50+ miles per hour.  This can wreak havoc on many wind systems.  Good to see options for urban dwellers and businesses that work, too.

Looking more like an MLM (multi-level-marketing) ad site than an actual brick and mortar business, this Arkansas based company has a well engineered rooftop system for homes, businesses and windfarms.  You can connect them to the grid, storage systems and more, plus – they’ll engineer a system for your home/school/warehouse.  Can’t slight them too much on the site, it has all the information there: the jaded eyes of webbys may pass them up though.  Worth a hard look, including their FAQ page.  They also do residential hydro.
