If you don’t care what you pay for electricity, this makes perfect sense.

These guys have been raising capital since they were founded 12 years ago. Will investors ever see a dime in return? No. As it has been shown consistently, small wind is a nonstarter, and the only thing special about this …
Flower Turbines: Just Another Exercise in Futility in Small Wind Read More »
Because commercial wind turbines capture more than 80% of the theoretically available energy from the wind, these people’s claim that their devices double the energy output is a lie.
Conventional wind turbines extract about 90% of the theoretically available kinetic energy from the wind, making this statement at left a bald-faced lie. In addition, there is a reason that small wind no longer exists: it’s inherently impractical; the output …
I have to admit that I have a morbid curiosity about clean energy technologies that have no prayer of success, but whose founding partners vigorously hawk as the future of renewables, while they aggressively cultivate investors. “Hydro Wind Energy” writes: …
Other than common sense, there is nothing that prohibits investors from pumping cash into companies like Flower Turbines, that one day, owners claim, will build and sell devices that capture small amounts of wind energy. In fact, until about a …
Here’s a piece from Fossbytes, the same people who claim that the costs of maintaining EVs is greater than that of gas- and diesel-powered vehicles. A cargo ship named the Pyxis Ocean equipped with two 123-feet-tall WindWing sails embarked on …
If you’ve ever wondered how the physicists who have been studying how to extract the most energy out of the wind for the last three hundred years, whose work has been greatly accelerated in the last few decades, these people …
The people from Wind Catcher say their product is “perfect for camping, RVing, and off-grid living. It’s lightweight, easy to install, and produces enough energy to power your devices and appliances for days.” Of course, “easy to install” is a …
Assume the turbine presented here is 1.5 meters tall, as shown, and let’s say 0.5 meters wide, meaning that its swept area is 0.75 square meters if it were refashioned into a standard bladed turbine, spinning in a circle, with …
