Shimizu says the energy from a single typhoon can power Japan for 50 years, and with the help of his turbines, the country could become a "super power of wind." Even if his creation can capture all that energy, though, it will likely be tough finding a way to store 50 years' worth of power at this point in time. We might not have the battery tech capable of that just yet. Shimizu's company installed a prototype earlier this year in Okinawa, and it's now gunning to build one either on the Tokyo Tower or at Japan's National Stadium, where the Olympics will be held in 2020.
