Wind Energy Physics Quiz
Here’s a video that will test your understanding of physics, if you don’t have a 5th or 6th grade education. It’s a wind turbine on a kite powered by eight motors that push the device into and through the wind …

Could This Be the Safest, Most Powerful Wind Turbine in the World?
Here’s a short video on a new wind turbine concept. A breakthrough? Ahhh…..no. This is bulls***, for three main reasons. a) Wind power is a function of the area of the turbine. Tiny turbines necessarily generate tiny amounts of power.

Kitepower? Ahhhhh….No
Occasionally I like to apply some mathematics to claims that are made about renewable energy technology. Pictured here is something called Kitepower, another variation on the theme that we’ve seen so many times over the years.

Portable Wind Turbine
Campers in remote areas can charge their cell phone with this portable wind turbine. Two points: 1) On mountaintops, as shown in the video, this will work, but not in a place of low/no wind, like forests. 2) This competes …

Converting the Entirety of Americans’ Energy Use to Wind
A reader asks: How many windmills would we need per person to replace fossil fuels? How much room would this take up? In the United States, we consume 5.4 terawatts (5.4 * 1012 Watts). The average wind turbine is a …

“Nano Wind”–Bad Idea
Using small pieces of solar PV to run low-power devices is a good idea. Adding what could be called “nano-wind” (i.e., wind turbines even smaller than “micro-wind”) isn’t. All this does is add expense–both capital and operational.
Analyzing a New Wind Turbine
Here’s what the inventor of a new wind turbine tells us in the video below: He’s standing in a wind speed of 3 – 4 mph (let’s call it 3.5). The device is 16′ high, and the blades start at …
