Finding a cheap way to produce hydrogen would be a big step toward reducing our dependence on fossil fuels. It would lower greenhouse gas emissions as burning hydrogen releases only water vapor. Researchers at Penn State University have made a breakthrough that will enable sewage and biodegradable garbage to convert into cheap hydrogen.
Implications - Fossil fuels are growing increasingly scarce and there is no doubt that alternative sources of energy are the future. With that being said, companies that move towards making these alternatives cost-effective and convenient before fossil fuels run out altogether will find themselves well ahead of the curve. Inventions like this have a ton of promise, and are poised to dominate the markets of tomorrow.
