As technology progresses, there are more and more innovations in alternative energy. One innovation that sparks interest is the wind energy initiative taking place in Japan. A lot of negative feedback revolves around inefficiency in wind turbines. What is the solution? To answer this dilemma, a team at Kyushu University has created their own design. The model is called the "Windlens" and includes a perimeter around the blades rotation that creates a focal point and allows wind to rush into the blades at faster speeds. This in turn creates a greater energy output. The Japanese models are still in the testing phase, but the future is promising. Another idea that can change wind energy in the future is the addition of hexagonal bases that float on the ocean surface. The new turbines are then attached to create a wind field. This means cheaper input and greater benefits.
I find this article truly interesting. After the nuclear plant disaster, I was pretty sure that Japan's government would lean more towards alternative energy. The wind turbines that are being tested seem like a simple design and it's curious why no one has thought of it before. Also, the fact that these turbines are quieter and essentially float on the water means that there will be a minimal effect to marine life. Globally, installation of such devices offshore could bring significant benefits. I think specifically of island communities with smaller populations. They could provide just about all of their energy needs from such wind systems. The concern that I have is for huge storms. Usually the open sea during tsunami's and such receives less, if any damage, but situational considerations would have to be a concern. What works for one place may be detrimental to another.
