New Wind Turbines Could Power Japan for 50 Years After a Single Typhoon
Atsushi Shimizu is the inventor of the world's first typhoon turbine-an extremely durable, eggbeater-shaped device that can not only withstand the awesome forces generated by a typhoon, it can convert all that power into useable energy. Shimizu's calculations show that a sufficiently large array of his turbines could capture enough energy from a single typhoon to power Japan for 50 years.
Given that Japan is currently dealing with
an energy shortage
The typhoon turbine differs from conventional turbines in two important ways. It works on an omnidirectional axis that allows the machine to survive unpredictable wind patterns, and the speed of the blades can be adjusted to ensure they don't spin out of control during a storm.
Tests of a prototype yielded 30 percent efficiency, which is 10 percent lower than propeller-based turbines. The difference, of course, is that Shimizu's turbines can actually survive a storm. Back in 2013, Typhoon Usagi destroyed eight conventional turbines, while damaging eight.
A functional prototype was installed near Okinawa earlier this summer, and the next big step is to test the device under high-wind conditions. All that's needed now is a typhoon.
It's not immediately clear where all the incoming energy will be channeled, whether it be sent straight to the grid or stored in large batteries (
