Episode 430 - Using Corn to clean water, and new wind turbine designs

Clever engineering can turn waste products into planet cleaning tools. Corn is America's biggest crop, but it's incredibly wasteful. Corn waste can be given a second life as activated carbon to help clean water. Corn waste makes for an efficient water when it's turned into activated charcoal. Wind turbines have to be carefully placed and located to maximise their efficiency. When designing a wind farm, the location and style of the turbine can greatly impact generation. Which design is better for wind turbines; vertical or horizontal? Vertical wind turbines aren't as common, but they can work together to boost efficiency.
