when people make comparisons between pump gasoline and hydrogen fuel; guess what , "gasoline" is in fact a simple molecule of one atom of carbon and one of hydrogen and the energy of molecule is the hydrogen so we are already using hydrogen.

- the big picture.. You can live without a car, already. You can't live without the fuel to run industrial civilization

walter0bz - 8.6.2011 20:59:44
>>"but the biggest problem at the moment is how to extend a cars range beyond what batteries can carry, " No. Cars, full stop, are the least of our worries. You can run industrial civilization on electric trains between cities, and electric trams within cities, and bicycles for short range. The real problem is, whether or not we can keep such complex technology at all withou the fossil-fuel energy boost. When it comes to Sustainable, biosphere has many superior systems already..

walter0bz - 8.6.2011 20:57:54
- No. I fully understand Hydrogen can make cars work. The question is "How Many". I claim, the energy will no longer be abundant enough. The proficiency of hydrogen is a moot point. We have cars not because of "internal combustion engine vs hydrogen", but because of millions of years of stored solar power in coal,oil,natural gas that allows us to release it rapidly. Without fossil-fuels, the superior transport will be Bicycles. (if we can still make such precision items..)

Its true that it requires a fuel source, but the biggest problem at the moment is how to extend a cars range beyond what batteries can carry, without the use of fossil fuels. You are ignorant for saying this is not possible with hydrogen.

walter0bz - 29.5.2011 4:32:15
hydrogen fool-cells - the car industry pretending it has a future. Just face the truth - after Peak-Oil there will be no motorized transport available to common people. hydrogen is an energy carrier not an energy source, so its highly deceptive to talk about it filling a similar role to fossil-fuels.

lol, then the answer is simple, the exaust will be an internal still, one of the ways t get clean water lol, go figure. So any other probs? the tailpipe can be stuffed back into the water tank if thats to hard.

Vulcan750L - 2.5.2011 15:51:00
Hydrogen engines do emit water vapor. The water that comes out of the exhaust pipe is mostly water vapor because it is hot so it is a steam. Some of that water condenses right away when it hits the cooler air and turns back into water droplets that drip out of the tailpipe. But, the water that drips out eventually evaporates and turns into water vapor. Where do you think the water vapor in the air comes from? It comes from evaporation.

lol you mentioned ev's, thats what pulled it off subject lol

Me102288 - 2.5.2011 13:03:12
lol, so everyone thinks global warming is caused by water.. I find that hard to believe, global warming is caused by us and the billions of vehicles spewing noxious gas's into the atmosphere. Earth never had a problem until we "evolved" And your still argue'ina moot point, since engines running hho dont spew humidityy, the emmision is water

Vulcan750L - 2.5.2011 8:34:05
And spamvigilante is right. Water vapor is a greenhouse gas. Water vapor and clouds are responsible for about 75% of global warming. Some global warming is good. If not for not for greenhouse gases, the Earth would be a very cold place, maybe a permanent ice age.

Vulcan750L - 2.5.2011 8:28:37
The other "pollutants", like nitrogen, nitrous oxide, sulfur, and soot particulate matter (carbon) are also good for plants. Some of that stuff is harmful to humans and animals if we breathe in too much of it at concentrated levels. But, you rarely see that kind of emissions anymore due to environmental regulation controls, at least not in the US and Europe. Developing countries like China and India are in the process of implementing similar regulations.

Gravity has no effect on humidity. Clouds, however, will rain if there is too much water droplets built up in a particular cloud. It is possible to have more clouds and higher humidity as the earth warms. Water vapor (humidity) and clouds are not really the same thing. Clouds are tiny water droplets clinging on to tiny airborne dust particles, mostly pollen, and are high up in the sky. Water vapor is all around you, including in your house and the room you're sitting in.

Me102288 - 29.4.2011 18:04:13
yes I know, I have never argue'ed co2 is bad, and humidiity no matter how high will always fall because of our little friend gravity. But anyway, I find it funny he doesnt mention all the other nasty chemicals we have been pumping into the atmosphere for the last what 100 years? Ha I remember a facility in Nanicoke that turned they're scrubbers off at night to save money :-\  Could see the huge yellow stream across the horizon. Sad.

Vulcan750L - 28.4.2011 5:01:02
Water vapor are not necessarily clouds. Water vapor is the water contained in the air. Look up the word HUMIDITY. CO2 is also part of the Earth's atmosphere just like clouds and water vapor are. CO2 has also been around long before man and used to be much more abundant. Having an atmosphere rich in CO2 is not going to destroy the planet.  Plants thrive on CO2. You don't like plants?

Vulcan750L - 27.4.2011 9:20:25
Hydrogen cars do not run on water. They run on hydrogen. Is hydrogen free? We've covered all this already. Why don't you just reread everything I've already told you. You seem to have a memory or comprehension problem. Or are you just really dense and still don't GET IT.

Vulcan750L - 27.4.2011 6:39:24
Hydrogen has to be made from electricity. This results in the loss of energy in the process, whereas, EVs can take the electricity and store it directly into the battery with no conversion loss. Hydrogen also leaks out of any container that stores it. Is this efficient? Would you buy a gasoline car with a gas leak? Is this safe to park or store in your garage? Hydrogen is an explosive volatile gas.

Vulcan750L - 27.4.2011 6:30:02
So tell me, what does a hydrogen car costs compared to an electric car? It costs about 3x as much. Is that competitive? A hydrogen car also HAS TO have very expensive infrastructure put into place BEFORE it can become viable. Electric cars DO NOT have to have ANY infrastructure at all to be viable. But, infrastructure will make it more convenient and give it much more flexibility. Electric hybrids can refuel on gasoline if or when needed like a normal car.

Me102288 - 27.4.2011 5:52:26
we have a 175 foot well.and a reverse osmosis system, we havent paid for water for 10+ years. Cant compet with EV's huh.. Einstien calculated the energy contained in 30 litre's of water equals the equivelent of 30 MILLION gallons of gasoline, compare electricity vs. an atomic fuel? lol not in combustion

spamvigilante - 24.4.2011 19:46:45
I'm sorry that you are so dim as to not realize that in the case of burning hydrogen, the water vapor in the atmosphere WAS NOT THERE. Then, you burn hydrogen and IT IS THERE. Obviously, this simple fact eludes you. ADDITION of water vapor... addition of a greenhouse gas that did not exist prior. HOW STUPID CAN YOU POSSIBLY BE?

Me102288 - 24.4.2011 15:39:23
over simplifying? if you honestly think math states you cant get more energy from using less energy, go lookup a fuk'in wind turbine. I'm tired of ppl over complicating simple things to bullshit other ppl. water vapour in the atmopsphere are called clouds, they been around before Man, and the world didn't destroy itself.. WE ARE THE ONES DESTROYING THE PLANET.

If you wanted you could pipe highly concentrated CO2 released from coal fire electric plants to grow the algae then in turn use the algae as a fuel source which would then turn into CO2 to sue for the next generation of fuel supply.

Theimmortalwhitewolf - 13.4.2011 0:28:53
well there is hope in researching fuels made from algae. Since it absorbs CO2 during its life span it removes CO2 even though it gets released back after its burnt you have a fuel source that will constantly replenish itself through photosynthesis. Blue algae currently researched in Spain, a simple number crunch shows a roughly 170 mile^2 area could meet all the oil needs of the USA.

spamvigilante - 12.4.2011 19:42:08
So if you have the secret to cheap and abundant hydrogen, why is the vast bulk of commercial hydrogen created today from liquified natural gas and resulting in large quantities of CO2 into the atmosphere? Do commercial enterprises like spending more money than they have to in order to create a product for sale? Do they perform this function just to make me happy? DUH! Sorry, the facts prove your spurious claims as dubious at best; fraudulent in most likelihood.
