Ford, the second largest car maker in the world, celebrates its 100th birthday this month. And it is already looking forward to its next 100 years. Ford expects to have nearly half its cars powered by fuel cells by the year 2050.
In the meantime, another car maker in the US, General Motors (GM), is building the technology for cars to be powered by fuel cells.
So, what makes fuel cells so special? Why are car makers so enthusiastic (热忠的) about them?
Fuel cells are based on an electrochemical process. They change chemical energy from hydrogen (氢) and oxygen into electrical energy.
Fuel cells pollute much less than traditional power sources. They produce little more than water as a byproduct. Car makers expect them to cut CO2 emissions (散发) in half and so make cars more environmentally friendly.
Fuel cells are not dependent on oil supplies. Instead, they run on hydrogen, the most common element in the universe. And they can be refueled. Car makers expect fuel cells to lessen the industry's need to rely on decreasing oil supplies.
Using fuel cells, without the traditional motor, engineers have many more possibilities for developing cars.
A fuel cell frame can last 20 years, so car bodies could change with drivers' needsor even with the seasonsand be replaced at will.
Owners could switch from a sports car to a family car while keeping the same fuel cell frame. This is a much cheaper solution to buying a whole new vehicle.
“A fuel cell car is more than just a new concept car, it's the start of a revolution in how cars are designed, built and used.” Said GM Chief Executive Rick Wagoner.
While this may sound great, fuel cells are still too expensive to produce. For cars, they can be ten times the price of normal engines.
The current test models can cost US $ 1 million or more.
Besides Ford and GM, a number of other car makers are now testing fuel cell vehicles. And all are aiming for mass production by 2010. By that time, the cost of buying a fuel cell car should be as affordable as that of a traditional car.

[ ]

New York , May 25? Millions of volunteers (志愿者)joined in a long chain spreading 4 125 miles across the world's richest nation Sunday and burst into songs , reaching the highest development in the Hands Across America road to raise 50 million for the nation's homeless and hungry.

The last people in the line were Bill and Mary Jones and their five small children, who lived in a family shelter (收容所) for the homeless in Venice, California.
The chain was not unbroken some gaps were planned for safety, others opened where there were not enough people to cover the ground. But along most of the route, the healthy joined the sick, beautiful film stars , homeless beggars , wealthy artists , poor children and President and Mrs Regan all took places in the long line.
