people Perpetual Futility A short history of the search for perpetual motion. by Donald E. Simanek Popular histories too often present perpetual motion machines as "freaks and curiosities" of engineering without telling us just how they were understood at the time.

In fact these units can be installed on existing power poles in rural areas, to catch the wind and send its energy back to the plant.”- Raymond Green, Inventor In 1913, Inventor Nikola Tesla patented a bladeless steam turbine that he claimed was the most efficient and the most simple rotary engine ever designed. Due to a lack of high-quality materials, Tesla was never able to properly build his engine. One century later, we now have all the materials needed to build Tesla’s turbine, and in 2010, a patent was issued to a company called Solar Aero for a wind turbine based on the Tesla design. Their turbine will be presented in this article along with other bladeless turbines like it that will allow us to revolutionize energy production for the entire world. Current wind turbine technology with rotating blades is both inefficient, and causes noise pollution, which has been reported to have detrimental health effects on residents living nearby.
