6 FAQs about [Kyushu wind turbine blades]

Will Kyushu's wind turbines take advantage of Japan's coastal wind power potential?

To take advantage of Japan's coastal wind power potential, the Kyushu team has also designed a hexagonal-shaped base for the turbines that would be low in cost, but still strong enough to endure marine conditions.

How much power does Kyushu wind farm generate?

The wind farm’s annual power generation is expected to be 500 million kilowatt-hours, equivalent to the power consumption of 170,000 households. The generated electricity will be sold to the transmission and distribution company of Kyushu Electric Power for ¥36 per kilowatt-hour under the feed-in tariff scheme.

Can a wind lens turbine be used in water?

The mechanism of the Wind lens can be applied in the water also. Development of shrouded water turbine is ongoing at Kyushu University. A water channel experiment with small Water lens turbine demonstrated 2.5-time power enhancement using the same diffuser design used in the Wind lens turbine .

How much energy does a wind turbine generate in Japan?

While energy from wind turbines currently accounts for less than one percent of total power generated in Japan, the new breakthrough in design provides ample reason to ramp up production.

How will the Hakata-Bay wind farm work?

offshore farm plan following the successful result of the Hakata-Bay pilot plant. It can be expanded into multi-triangle body. This farm will accommodate medium size (300 kW at a wind speed of 12 m/s) Wind lens turbines according to the current plans.

What is a 100 kW wind lens turbine?

Currently, more advanced 100 kW Wind lens turbine is being designed and under development. This new model will have active pitch control system and semi-active yawing system. This new 100 kW Wind lens turbine will be also a part of multi rotor system (MRS) for larger rated power output.
