Hydrogen could be fuel of 21st century.

Some day, you may fuel up your car in your own yard with a garden hose. Does that sound futuristic? The future may be closer than you think, thanks to a recent discovery by Peter Iyere, assistant professor of chemistry, Tennessee State University, that promises to be not only good for the environment, but perhaps a partial solution to America's dependence on foreign oil sources.

Iyere has uncovered a method of producing hydrogen from its most common source--water--using such simple materials as aluminum foil in the production process. This groundbreaking discovery makes the production of hydrogen easier and much more economical.

Presently, hydrogen is produced from hydrocarbons or by electrolysis, a method of passing electricity through water, but the process is quite costly. That's why hydrogen is not utilized widely as a fuel source today. However, researchers are working towards more widespread use of it, and the first hydrogen-burning car already has been produced in Germany.

Presently, the space shuttle is the...
