Poo-powered Hydrogen Vehicles
Sounds (or rather, smells) promising.
This brings recycling to an entirely new level. Somewhere in a waste facility in California, bio-solids are being processed to create electricity and hydrogen. Although hydrogen is an abundant element on earth (and the universe! Space travel fuel, maybe?) but is still very costly to process. Critics of hydrogen vehicles will also argue that the production of hydrogen emits as much carbon dioxide as conventional petrol-powered cars.
