Eight Technologies to Save The World
1. Home Hydrogen Fueling Station
What could be greener than a hydrogen
car in your driveway? Try a
solar-powered hydrogen fueling station
in your garage. Australian scientists
have developed a prototype of such a
device. It's about the size of a filing
cabinet and runs on electricity
generated by rooftop solar panels.
The first version is expected to produce enough hydrogen to give your runabout a range of some 100 miles without emitting a molecule of planet-warming greenhouse gas. Road trips are out of the question, but it's enough juice for running errands or powering fleets of delivery trucks. Tests of the home fueling system began early this year with commercial trials two years off.
