Despite the global trend towards renewable energy, Japan's domestic efforts were greatly hampered by the after-effects of the Great East Japan Earthquake. While the country is behind where it would like to be, new advances in renewable energy are providing hope for Japan to get back on track. This episode will introduce 2 companies with very different ways of harnessing energy from the earth to generate electricity. One has developed wind turbines with a compact design that allows them to withstand typhoons. And the other has created unique waterwheels that are able to generate electricity from small streams and agricultural runoff.
