iamjason discovered 5 months ago- Vertical-axis wind turbines are worth looking into.

- The Windspire is a propeller-free, 30 foot tall windmill for home electrical energy generation. Propeller-free theoretically means fewer dead birds, less noise, and better ability to collect energy omnidirectionally. Nice design, but requires ownership of some yardspace and an unobstructed overhead area. Not great for a tightly packed city like LA or NY.

- The Windspire has a propeller-free vertical-axis design, and is expected to produce about 1800 kilowatt hours per year in 11 mph average wind conditions. That amount of wind power is roughly 25% of a typical household's energy (or much more if you are particularly energy efficient). The Windspire is 30 feet tall with a two foot radius, sized below typical residential zoning restrictions. Guidelines for installation sites are generally half an acre of land and relatively windy locations. The Winspire has just passed the ETL safety certification, which means it's ready to go to market. It is expected to be released this spring, and priced at $3,995.

- Warning, all. Little Snitch warned me this site attempts to connect to...paypal.com.something rather, believe it or not. For those who don't know, Little Snitch is a mac app that does just that: warns you of surreptitious 'knock home' website activity.

- The Vertical-axis wind turbines is the most popular electric sources in the future
- Folkers rated 5 months ago
- From the page: "1800 kW per year. Suppose you pay a relatively high energy price of $0.13 per kWh you consume it would still take 17 years to justify the investment. It is 27.7 years if you pay the US average energy price of $0.08 per kWh. So even if you could install it yourself for free how long do these things last exactly?"

- This looks really interesting. I'd buy one if I lived in a place with wind averaging 11 mph or more. About $5,000 installed and it will produce about 25% of a normal household's electricity.
