Futuristic Off Shore Wind turbines: The Wind Lens

Kyushu University professor Yuji Ohya has developed an ultra efficient wind turbine which is unlike anything we have seen before. At the Yokohoma Renewable Energy International Exhibition 2010, Professor Ohya and his team unveiled the Wind Lens, a honeycomb-like structure which supposedly triples the amount of wind energy that can be produced by off shore turbines.

The basic tenet of the Wind lens is kind of like a lens concentrating solar energy onto photo voltaic surfaces, here the ring like structure “the hoop” acts like a wind collector concentrating the wind onto the turbines. The structure has a 112 meter diameter and supposedly will also reduce noise pollution. According to reports verification experiments show that wind lens turbines produce 3 times as much electricity as those without a hoop.

According to Professor Yuji Ohya  even a gentle breeze can accelerate the revolution of the turbines considerably. The 2.5 meter-wide blades can, at with wind speed of 5 meters a second, can provide a sufficient amount of electricity to power an average household. There is a diffuser placed along the edge of the turbine which does not rotate there by reducing the vortices and increasing efficiency.

The smaller size of the turbines could in the long run make it cheaper to manufacture, for now though they are pricey.

My Opinion

To me anything that interferes with the Ocean and is man-made is not safe until proven safe for the environment around and in the Oceans. So though impressed by the design aspect and the increased efficiency of the wind lens I will wait to see the environmental impact studies.

    All that it could possibly do is create an artificial environment for fish and other sea life to breed. Its not polluting anything and no risk of oil spills.

    I disagree with you on this point i feel that any step away from coal and fossil fuels is a good idea…. how can you a green advocate be not all for a green idea?

    pull your head in you sound like an underprivileged arts student.

    that the defining chertctarisaic of the Left is their belief in equality, so the defining characteristic of the Right would be the belief in, um, not equality (Auster’s better at criticizing the Left than coming up with alternatives).
