The dramatic vista of noisy wind farms featuring towers that go the length of a football field will soon change, if John R. Tuttle has any say about the matter. “We’re nearing the end of that road,” says this engineer and inventor, who has multiple patents pending for his direct conversion wind-to-electricity system known as the Windpipe.

The most remarkable detail about this simple mechanism is that has no visible moving parts – only a hollow pipe with a configured nozzle that draws wind down its length, then converting it to electricity. The Windpipe requires no propellers, turbines, or rotating machinery. And unlike numerous propeller-driven towers, does not stop generating electricity when the wind velocity reaches higher than 55 miles per hour. Read more of this >>

Not all greenhouse gas is going to waste, some of it is generating electricity. At the gigantic Denver Arapahoe Disposal Site, known to mot natives as DADS, Waste Management Corp. and the city of Denver are now capturing the greenhouse gas, methane –  generated from decomposing rubbish — and powering four Read more of this >>
