Interesting article tucked away in the Business Section of the SF Chronicle: Small, Vertically Spinning Wind Turbines — for your roof.
At $5,000 a pop and only generating 10% of needed electricity for a home it’s not ready for prime time, but it shows innovative thinking and hands-on problem solving which we’ll need a lot of in the coming years. I’d also want to know what the spinning sounds like, in the house or to the neighbors; what the torque does to the supporting pipe — you know, wobble, damage to the roof, maintenance costs, etc. But hey, keep trying!
