If a majority of our automobiles were replaced with vehicles which operate on hydrogen powered fuel cells, how could massive amounts of hydrogen be stored safely for refueling? How safe are these cars when the fuel tank ruptures due to collision compared to current gasoline/diesel ones currently in use? How many miles will the vehicles be able to go before refueling?
What do you think the fuels of the future are or gonna be?
I think Fuel Cells Could Work,i read this some where on how it works. The fuel cells join with hydrogen atoms and create H2O=Water. We all Know Water is something we can drink, so next time your thirsty for something to drink, just pull over and put a cup under the tail pipe!
You got yourself some fresh made water!!
I also have read about hybrids. It's more fuel effciant,but still polluetes the air right?
Link To See How Hybrids Work:
I caught part of a show regarding non-conventional automobile fuels, including fuel cells, high powered electric cars (very fast and quiet), hydrogen, and very high mileage/high powered vehicles (e.g. 140 MPG with lots of horses). After listening to this for a few minutes, it seems like electric motors have something to offer to aviation. Thanks
Its a terribly exciting time for alternative car energy and many technologies are fighting it out for domination in the future. Some are very experimental while others are already available. The list is not small making the debate quite complicated. Which of the following would you bet your money on? And why? Or perhaps you have one not listed below:
Electric Hybrids & Car batteries
Plug-in Electric Hybrids
Hyrdogen Fuel Cells
Coal based synthetic or Coal-to-liquid
told by student that Hummer already has one, and that the military has been experimenting with them because of how quiet they are. I showed my class a "Cars of the Future" film about hydrogen powered vehicles. They seem to have endless possiblities, and they are safe. Solid hydrogen fuel in the form of metal alloy can be dispensed and stored. Iceland already has a Shell station that not only dispenses hydrogen fuel but makes it right on the site, so that no delivery trucks are used. The only emision from the engine is a few drops of water. The car that was featured had a chasis with the engine and fuel cells under the floorboard. All that was needed was a body to be lifted onto it.
1. Space shuttle's main engines (not the boosters) are hydrogen-powered.
2. There are (experimental) hydrogen-powered cars which actually burn hydrogen instead of gasoline (I'm not talking fuel cells, but hydrogen-based combustion engines!).
Considering that, would it be possible to have jet planes using hydrogen instead of kerosene? Would the re-design costs for the engines be prohibitively high? Would keeping the hydrogen liquid be too expensive at the airports and maybe impossible in the plane tanks? Would it be too dangerous, because of hydrogen's high inflammability?
If not, why is no-one working on that? Why is there development on cleaner cars, but not airplanes?
many people are currntly using crude home made hydrogen fuel in thier fuel injected engines.
Do you suppose they are causing greater fiscal damage that the benifits of thier 'fuel cells' are unable to counteract?
Fuel cell technology being developed by several automakers, namely Honda and Chevy, is a non-combustion form of energy unlike liquid hydrogen which essentially uses the same engine structure as conventional cars. This require liquid hydrogen to be kept in the vehicle at 420 degrees below zero which is costly. In fuel cells, hydrogen based cells are kept on stacks. A hydrogen – oxygen reaction creates electricity that powers the car. The fuel cells are refilled with the hydrogen chemical.
I am curious as to how fuel cells will work in automobiles
I know we don't "as of yet", but I'm curious as to the "principal" of their operation.
