The hydrogen vans are here; one problem -- where to fuel up?? Private enterprise and government can't even facilitate the availability of alternative energy sources. E-Flex vehicles are a joke - ethanol blended gas is a rare find. I think the only available hydrogen fueling stations are in Norway.

Now this's really a alternative LOL. Do you know how to make hydrogen? don't make me laugh. By the way i heard that in japan, honda have a small island were they have a dam producing eletricy for almost no population and they use the excess of electricity to make hydrogen... in the real world it's tha same LOL

Who will service these cars as a hydrogen leak will blow up a whole service station. Hydrogen requires 6 times less energy to be ignited than gasoline. A little static is all it takes.

Who will insure these cars. Does insurance include getting burned by an invisble flame - better check that Katrina clause.

Hydrogen embrittles metal so you will have to get new tank, gas lines and exhaust often. Hope they come with good warranties.

Where to park? You can't park in underground parkings with Propane vehicles.

Where to fuel up? Iceland?

Sure emissions at the tailpipe are great, but you had to make the hydrogen using electricity that still comes mostly from dirty sources so you really saved nothing in emissions.

This data from the European Fuel Cell Forum, page 24, shows that a Hydrogen Internal Combustion and Electric Vehicle hybrid got the fewest miles for a unit of energy when compared with fuel cells, which we already know are massively inefficient, and every other technology. Pure electric cars still come out way ahead.

Stop the hydrogen non-sense.

Forgot the link, as I often do, sorry:

I am not for H2 but let me clear something up as I hate misinformation:

A H2 leak will not blow up anything unless it's confined. H2 is lighter than air so all you need to do is vent the garage with roof vents it it will escape on it's own. Park in open air parking garage and no problem at all. LPG is heavier than air that's why it's banned from underground garages, it'll pool in a low spot and wait for a ignition source. We know how liquid fuels act when spilled so nuff said there. Most times when I see something on a H2 vehicle they are using carbon fiber tanks not metal.

Like I said not for H2 as it has many problems:

Current production methods use a lot of energy are poluting.

No infrastructure in place.

Tanks are bulky and hard package in a smaller vehicle.


Infrastructure it the big one, we have it electric distribution, water, natural gas and liquid fuel. H2 is a diffrent animal so it would need it's own network. For those that say ya but you have water and electricity there's that efficiency problem. Add up transmission losses and conversion losses and you've probably lost 50% or more of the orginal energy.

Nope can't see H2 working any time soon but please leave the fear-mongering up to the Bush Whitehouse. I have a feeling in my gut...

Scientists and engineers haven't discover yet that there is a gain of energy output by the electrolysis of water method. You add small electricity to water and then you end up with more energy then you begin with. It's because they wrongly assume to begin with that there is no energy in pure water, That's the mistake. Let's say that one gallon of water have one unit of energy then you add let's say 15% energy with electrolysis and you end up with 1.15 unit of energy in the form of h2 plus oxygen. You have to assume that there is energy in water but a fuelcell or h2 ice(conventionnal internal combustion engine) cannot burn direct water, it had to be change to h2 plus oxygen . The miracle is that there is no pollution involve except for the electricity. If you deduct the 15% energy content from the water instead of adding it up then you have ufo technology if you recycle the water exhaust back to the tank. So with this method you have an infinite system of energy without pollution
and for free exactly like said in the bible when moses said to separate the water molecule in 2 to liberate the people .

The scientists and engineers have wrongly assume that there is no energy content in water. Let's say that there is 1 unit of energy in a gallon of water and if you add let's say 15% energy to that gallon in the form of electrolysis you end up with 1.15 unit of energy in the form of hydrogen plus oxygen. If you take the 15% from the water instead of adding it up and you recycle the exhaust back to the tank you have a system of endless energy like a u.f.o. So water contain energy and can be recirculate back to the original tank.

Hey A.Brien you forget that the small part of electricity it's not that small, and the majority of electricity is made burning oil, natural gas or coal, with very low yield. And in the electrolysis it's same, with a pound of water you can't make a pound of H2. Other thing, reciculation it's only done in fuel cell.

The world needs more scientists and engineers...
