Wall sized Television, a car that runs on processed C-one and army of robotic soldiers, our space luxury resorts and human side boards, no it's not a movie as we race into the near future to see where fantasy becomes fact.

Welcome to the year 2060 as you'll notice the world has changed quite dramatically in the past 50 years, several things are bigger, world's tallest skyscraper 1/2 mile in high but most things are smaller. Nano-tech medicines cure all forms of cancer, some things are faster hyper-sonic flight from New York to Tokyo takes two hours, while other things last longer average human life span 125 years. Of course these are just predictions, will they ever be reality? What technologies today will revolutionize tomorrow's personal transportation, by onyx, warfare, home entertainment and space exploration and why bother even trying to predict what's coming. Forecasting the future is very important in a couple of levels, if you can't anticipate what's going to happen you're going to be stuck reacting to what's happening. A good place to start on your road trip into the future is on the road.

What would tomorrow's wheels be like? How about a vehicle that uses the most abundant element in the universe as a fuel, it's only a mission of water vapor and a little heat, it's twice as efficient as today's combustion engines and you can refuel the vehicle at home, no fantasy just such test vehicles are already on the road, get ready for the hydrogen revolution.
The hydrogen fuel cell vehicles going to do to today's cars and trucks what today's cars and trucks to the horses and buggy have done 150 years ago, this completely revolutionary approach automotive transportation.
Right now nearly every major automobile manufacturer in the world is working on hydrogen fuel cell technology, the technology that could begin to supplant gas burning vehicles in the next 15 to 30 years.

Fuel cell vehicle essentially is an electric vehicle but instead of using a battery to provide the power it uses a fuel cell to generate electricity on board, these are very high performance cars they have great get up and go, wonderful acceleration and really good driving performance.
This general motors hydrogen three-vehicle they are not a conventional vehicles but a fuel cell vehicles that are powered by hydrogen, the hydrogen stored in the back when the gas tank would normally be and under the hood is a fuel cell, the fuel cell system combines hydrogen and oxygen to make electricity which powers the vehicle, the waste product is water which goes out the tailpipe and heat which is thrown overboard in the radiator.

A fuel cell will continue to produce electricity as long as oxygen and hydrogen supply, fuel cells are different from batteries in this respect, batteries are self-contained and eventually run down if not recharged.
A common type of fuel cell uses a proton exchange membrane which is sandwiched between two electrodes, hydrogen gas is fed to one side while oxygen is fed to the other, the hydrogen atoms are attracted to the oxygen atoms but the membrane only allows the positively charged hydrogen protons through, electrons have to take the long way around this flow of electrons generates and electrical current.
Although the basic concept to fuel cells dates back to the 1890's it wasn't until the nineteen sixties, the fuel cell technology really took off.
