Attempting to continue our wind power theme, we were doing some digging and what we found was something truly spectacular. A California man has constructed a design that features twenty-five small turbines in lieu of the massive blades on a modern wind power plan. One day this may approach the production capacity of the behemoths. Doug Selsam's Sky Serpent is the right invention at the right time: traditional turbines are perpetually on back order, and he has 3kw of generation capacity that's far more affordable and requires fewer materials to build.Selsam, who attended college at UC-Irvine but didn't graduate, has very little formal training in the ways of physics or wind power, which is probably what left him prepared to break the mold. "This is a 1,000 year-old design" he says of the single-bladed turbine, "I knew if I could get more rotors, I could get more power." While on the surface that is in fact true, it flies against the dogma of the engineers and physicists that dominate the wind power community. The complicated physics of ensuring each rotor doesn't simply encounter the prop wash of the ones in front of it, may have been enough to drive them away. However, Selsam figured out a method: he's found the proper angle to align his string of rotors at in order to ensure they all have flow, and the optimum spacing for the rotors themselves.

Here's another take on the elevated rotor design for wind turbines. This design can put 25 rotors on a single cable.

WOW! 25 TURBINS IN ONE!---YEA. THE SKY SERPENT. Thanks 7HL'.

Except it takes a huge amount of space because you have to ensure it doesn't hit any others...And what about when the wind dies and it crashes to the ground?
