March 11, 2011—the day the Great East Japan Earthquake struck off the coast of Tohoku and caused a serious accident at the Fukushima No.1 Power Plant. Japan, which had relied on nuclear power for much of its energy, found itself at crossroads: how would it secure its energy future? Coincidentally, this was the same day that two odd-shaped wind turbines were erected in Fukuoka City. The wind-lens turbine, a turbine with a unique brim surrounding its blades, was the brainchild of Kyushu University professor Yuji Ohya. Able to generate three times as much power as conventional wind turbines, it was a dream-inspiring machine. On the same day that Professor Ohya made his case for the need to shift to renewable energy, the Great East Japan Earthquake struck. Previously, Professor Ohya had erected wind-lens turbines in China to provide energy for desert greenification, but they were destroyed, unable to withstand the harsh winds. As problems like these arose, Professor Ohya and his team resolved them one by one, gradually improving the turbine design. With very few high wind areas on land, how can Japan increase wind power generation? According to Professor Ohya, the answer lies on the ocean. His dream is to use floating wind-lens turbines to create offshore energy farms. Experiments are now underway, and his team aims to build an offshore energy farm that will someday produce the same amount of power as a nuclear power plant. This is the story of the researchers who worked tirelessly to develop the wind-lens turbine and the small factory workers who provided the technical support they needed. Above and beyond the goal of solving Japan's energy issues, their undertaking holds a clue for Japan's post-disaster recovery.
