New Japanese Wind Turbine Triples Power Output Without Increasing Size

Necessity, as we’ve all been told can sometimes be the mother of invention. In Japan, there is a necessity for a power source that does not require fossil fuels, since they don’t have any. So the Japanese invested heavily in nuclear power, which, at the moment, is looking like a tenuous investment given the recent Fukushima meltdown. Fortunately, they did not put all their eggs in one basket, either. In fact, researchers at Kyushu University, which houses the International Institute for Carbon-Neutral Energy Research, had a hunch that the answer just might be blowin’ in the wind, if only they could squeeze a little more out of it than what conventional technology would allow.

That’s when they came up with the wind lens. What is a wind lens, you ask, and what does it do? What does any lens do? It focuses. Except instead of focusing light, a wind lens, which is an inward curving ring around the perimeter of the circle inscribed by the turbine’s blades as they rotate, focuses airflow, directing and accelerating the air as it enters the blade zone.
