Selsam Small Turbines – Just Right for Residential?

Selsam

The bloggers at Engadget picked up on the Selsam small wind turbines, which look a lot like one of those amateur ham radio antennas we used to see on houses.  This small-scale wind solution is basically a single elongated shaft made of strong carbon fiber.  The carbon shaft holds rotors that range in size from 14-18 inches in diameter.  Apparently, the more rotors you have on a rod, the better output you get.  Invented by Doug Selsam, this 13-rotor small wind turbine can produce roughly 200 watts in 20 mph winds (or more in higher wind speeds).  It’s currently being tested and developed in California, so who knows, we may just start seeing stuff like this on top of houses and buildings?

Wind Could Power 20% of US Grid by 2030

Palm Springs Wind Farm

Here’s some interesting news: a new Department of Energy report claims wind turbines could generate 300 gigawatts of electricity — roughly 20% of the US electrical grid — by 2030.  There’s already a website in support of the news at 20%Wind.org.  The report doesn’t necessarily predict the future of the wind industry, but it paints a picture of what a particular 20% wind scenario could mean for the nation.  The wind industry currently produces about 17 gigawatts of electricity, so we’re talking about significant growth over the next twenty-something years.  That said, wind industry growth has been fierce in recent years and is on track to meet these numbers if growth holds pace.
