Wind Energy has often been touted as one of the most reliable sources of renewable energy. Efforts to harness this awesome power of nature commenced during the primordial age when Persians built the world’s first windmills. The designs of wind...

Astounding progress in just the short time scarce oil made energy expensive! Necessity is the ”Mother of Invention”, and the American ability for innovation and inventing is alive and well! Better we are challenged by this energy problem than waste good engineering on faster gasoline engined cars! The times of cheap oil are over, as world supplies dwindle, and a few smart break-throughs in Wind, Solar, Wave, Tidal and Geothermal technologies can rebuild a new and cleaner America. Great stuff!

Nice to see these designs. Unfortunately it isn’t possible to make real comparisons based on the figures presented. There is only one type of data that I would accept to install a turbine of my own, and that would be a graph of wattage produced plotted against windspeed. Only with that can we assess the output for a given location.
Quotes like ’20%-60% of a home’s needs’ are actually completely vague, where the device could be completely uneconomic or a nobrainer-buy, depending on the average wind of the location and average consumption of the home.
I appreciate that companies will provide figures in their own way, but when enquiring of any designer or manufacturer the first question should always be ”What are the wattage outputs from 1mph wind to 20mph”. I would like all eco-sites and publications to demand this.
Noise, maintenance, bird-safety and planning restrictions are all useful info, but real output data is vital.

It would be more interesting to see the actual efficiencies of these turbines. For example the windbelt works well only on specific wind speed and the efficiency quickly declines when the wind speed changes.
Awesome article.Great to see all of the creativity. The ROI is the critical factor tied in with the noise that is generated

It’s good to see that so much thinking is being given to this issue. However, since most of these are computer generated illustrations, I would have to guess that the devices don’t actually exist and that the output ratings are calculated ’guestimates’ and ”SWAGS”. When there are actual devices to fully test and, ultimately, purchase, let me know.
