uh, didn't that blow up the Hindenburg? maybe they are still perfecting the technology for the normal persons safety...anyone ever told you you resemble John List, the guy who murdered his family and began a new life for a bunch of years? American's Most Wanted located him tho!

Gasoline is much more explosive than hydrogen is, yet we use it safely (most of the time anyway).

I don't know about the more explosive bit. You sure about that? Take a gallon can of gasoline in a room and ignite it. Boom! the walls are black, but little else.

Take the same amount of H2 (of course, we have to have liquid H2 to be comparible). Light a match, and the room ceases to exist.

Hydrogen is definitely safer. Not only less explosive, but another safety factor, is that in case of a leak, the gasoline will surround the car...bad news if it catches on fire. With hydrogen, if it leaks, it will travel up quickly away from the car.

Gasoline is much more dangerous. The fumes tend stay low and ignite in a plume that goes in all directions and then the liquid gasoline is left to burn for a longer time and spread on the ground. Tests done on hydrogen tanks, where inceneray bullets were fired into them showed only a mometary flame that went up and away and that was it. But that was an outside test of couse. Putting a gallon of hydrogen in an enclosed area isn't an aproximation of a tank on a car which is used outside, and even if it were I'd rather be in the room with the hydrogen gas because it would be up on the ceiling anway. Have you ever seen a gallon of gasoline exploded? Bad news, far much more damage than black walls.
It's been a while since I read the account, but I believe more people died from jumping from the Hindenburg than from the flames.
Here's some interesting new research into the Hindenburg disaster:

Would you like to help pay to build the required infrastructure? Would you also like to indemnify manufacturers?

The fact is, hydrogen fuel cells are more fantasy than fact. Let business figure out how to get it to market and make it competitive with other fuels.

THEN and only THEN you can enjoy hydrogen power. Haven't you ever heard that patience is a virtue?

Scott D, I imagine u together with ur boss while u are continuing to say him "Heven't you ever heard that patience is a virtue? Heven't you ever heard that patience is a virtue? .."

In this world there are *some problems unsolved since centuries..

I hope to know anyone with one vitue today, patience is an economical quality.

I solved the problem of having a boss years ago. It's called self-employment.

Thanks for playing. ;-)

;-) thank u to partecipate too.

it all has to do with the Oil conspiracy. The technology is there the U.S. Government has just stymied it because the ability to gouge us is in oil and not water.

The oil companies did not come up with the laws of physics.

They would probably be happy to sell more oil, to the many new power plants that would be required to generate enough electricity to extract hydrogen from water, to run the nation's cars.

Blame the environmentalists....they are the ones that are slowing down the approval of the new power plants required to run cars on hydrogen.

Hydrogen is too expensive. In order to extract hydrogen from water, you need energy....lots of energy. This energy has to come from oil, nuclear or other alternative source.

The more hydrogen used in cars, the more electricity that needs to be generated. Right now, we don't have enough generating capacity to convert the majority of cars to hydrogen. In order to replace gas with hydrogen, many, many more power plants will have to be built, in order to generate enough power, to extract hydrogen from water.

It takes time to build so many new power plants. Most people don't want these in their neighborhoods, so there is a lot of opposition. Environmentalists also frequently oppose the building of new power plants.

Biological hydrogen production is done in a bioreactor based on the production of hydrogen by algae. Algae produces hydrogens under certain conditions. In the late 1990s it was discovered that if algae is deprived of sulfur it will switch from the production of oxygen, i.e. normal photosynthesis, to the production of hydrogen.

The sulfur-iodine cycle is a series of thermochemical processes used to produce hydrogen. The S-I cycle consists of three chemical reactions whose net reactant is water and whose net products are hydrogen and oxygen.

The sulfur and iodine compounds are recovered and reused, hence the consideration of the process as a cycle. This S-I process is a chemical heat engine. Heat enters the cycle in high temperature endothermic chemical reactions 2 and 3, and heat exits the cycle in the low temperature exothermic reaction 1. The difference between the heat entering the cycle and the heat leaving the cycle exits the cycle in the form of the heat of combustion of the hydrogen produced.

reference Wikipedia

This still requires sunlight. In order to produce enough hydrogen to run a signifcant portion of the cars, we would have to convert many millions of acres of natural environment, to algae bioractor "farms". Would the environmentalists really let us chop down forrests, or push out endangered desert plants and animals?

LOL, of course not!

That's also why we can't build a nuke plant in less than ten years!

RX8 comes with a hydrogen tank and does actually work with hydrogen, the problem is that if you're in a car crash and your hydrogen is hit there is a good chance that you will explode, apart form that you need a considerable amount of hydrogen to go around, you will end up giving the car hydrogen daily and there are not alot of hydrogen supplies around

It seems greed and ignorance are two large factors.

hydrogen is not the answer, it's expensive too, and also the oil companies own the world and aren't letting the car market move on to other possibilities. Maybe one of you who do nothing all day but ask and answer questions all day should go and invent perpetual motion so that none of us have to worry about an energy crisis again.

yes, ignorance is a huge factor about the problems in our life
