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 …

More on Video on Small Wind
It came as no surprise when the promoter of this small wind turbine was upset by my post the other day “Video on Small Wind,” in which I pointed out that his claims were preposterous. I began, “Will the wind …

Video on Small Wind
Will the wind turbine here generate electricity? Yes. Will it do so cost-effectively? Not in a million years. • Vertical axis machines are intrinsically left efficient than their horizontal axis counterparts. • This device invokes drag rather than lift mechanics.
Airborne Wind
The developments in renewable energy over the last decade can be summed up as follows: the winners have won and the losers have lost. The plummeting costs of energy from solar and wind have put extreme pressure on things like …
Details Released on 14-MW Offshore Wind Turbine
The cost-benefit analyses of offshore wind projects differ from those of their on-shore cousins, in that the installation of each turbine is a far bigger component of the total cost. For that reason, bigger is always better, and this is …
Notes of Healthy Living and Wind Power
I’m trying to lead a healthier life, getting more exercise, eliminating dairy, and cutting back on drinking. I put a shot of Lysol in my coffee just now as a replacement for milk, and this evening it will be a …

Sketchy Idea in Renewable Energy
Think about this. You’re driving along an unlit road, and your car passes one of these lamps, creating the gentlest of breezes that creates a tiny, almost imperceptible bit of light, shining on the road–behind you. Does that seem practical?
