These two wind powered generators sit on a hops farm a few miles from my house. They are about thirty feet tall, total. Their total diameter is less than ten feet each. They will generate electricity with tiny breezes of less than five miles per hour.
Here's the local paper piece on their construction. There's even a video. These turbines, clearly unknown to New York based media, are made by Mariah Power. They call their rotating turbines "Windpsire." Mariah's based in Reno, the equipment is manufactured in Minnesota. These units are specificalloy designed for home or rural use, not industrial apps, not with 100-foot towers. More cats are killed by cars than by windmills, you can look it up.
DO THE NUMBERS
Do the numbers, urges one talkback. "How much energy is recoverable, year in, year out, for vertical turbine blades? What percentage of the US' domestic energy usage does that amount to? This is very basic arithmetic."
Because home wind doesn't scale to utility-size we ignore it? In some cities it is now illegal to hang your laungry outside to dry. Might lower somebody property values, if they have any left. We need to grow up.
Boy, if I really thought all that mattered were some calculations and somebody's profit margin, then green tech is worthless. It's actually about what remains and what survives after we finish using all the resources we want and trashing everything we don't have any immediate use for. Even the direct psychological link between making some of your own electricity and thus becoming more aware and adept at NOT wasting power, is worth some investment. Now we flip a switch and let 'er rip. Most Amercian electric switches don't have timers, they just keep running. We don't even have off/on switches for our wall sockets. Those are standard many other places.
