    Look at the raw amount of energy it takes to put the shuttle in orbit.

    It takes 383,000 gallons of liquid hydrogen to put a shuttle in orbit. That's 1,450,000 liters, just to make things easy. Per liter, liquid hydrogen will yeild 9.3 MJ. That makes for 13,485,000 MJ.

    Gasoline contains 34.8 MJ/L. An equivalent amount of gasoline would be 387,500 liters, or 102,366 gallons.

    So, assuming you could actually use gasoline to launch a space shuttle (which you can't), it would be 1/4 the volume of gasoline.

    It's really not the incredible figure as you described it.

    Now, consider the above, and consider the properties required to achive such a goal, AND then consider if this is a truely a renewable fuel source? Remember, we only have one planet Earth.

    you could, but the tanks required to do such and the injection required to do such would be cost prohibitive. Why not nitromethane? It is a controlable fuel source- based upon carbon- and creates many times the energy of H2. I already know the answer, but what I am seeking here, is simple-why not do something, and again on the other side- why not do something?

    BTW- what was the most powerful explosion ever created on our planet? What was it's fuel source?

    It is. We can make it as quickly as we use it, and the raw quantity is present to allow us to take a portion of it without significantly impacting the environment. The biggest challenge is getting the source of electricity, which isn't an issue if solar, wind, or other sources of electricity get pushed into wide adoption and drop in price.

    I was just pointing out that the point Leighton was making about the raw quantity of hydrogen necessary to put the shuttle in orbit really isn't as remarkable as he was making it out to be. I wasn't really going into the differences of fuel sources for use in the shuttle program.

    Now understood, thanks for clarifing. I am sorry if it appeared I was jumping the proverbial gun.

    But there in lies the problem. Myself and Powerman were discussing this very issue- infrastructure- whom pays for it and how do you build it, and then at what cost? We do not have a Utopian society here in America- so someone has to pay for it, someone has to build it-this above all is why I do agree with, in part, of what Powerman was stating. Have you any ideas?

    True and that is pure liquid hydrogen which weight is a fraction of water.
    The hydrogen the OP is talking about is electrolysis from water which contains NO usable forms of hydrogen.

    What many people that have these devices on there vehicles confuse is the h20 (water)and h2 liquid (hydrogen) which i might add is kept very very cold and compressed. So after everything is said and done the OP is for a lack of better words "steam cleaning" the carbon off his pistons thus increasing efficiency for the time being. Until it comes to the warmer months like ALPHA said and he hyrdo locks his engine, which I hope doesnt happen and removes the water device he has on there. :)

    PLEASE READ all of the link.

    It'll happen just like everything else related to widespread infrastructure growth in the US. The government will push for it to happen. It's too early for both the sources of electricity and the technology surrounding the hydrogen itself, so it won't happen for a little while, but the "green" initiatives around wind and solar are pushing electricity generation in the right direction to make them viable as main sources (rather than the ancillary sources they are at the moment) for electricity 20-30 years down the road.

    Oh come on BR, I live in wind alley, have a look at goggle earth and see where the wind mills are here in the upper midwest- Avoca IA. you wouldnt belive how many wind mills there are, 100's of them- yes hundreds. Most of which- are locked.....why?

    Like I said before it's not that we cant- it's greed, not need, that fuels all of this.

    I will not go political with this- as it's not allowed here. But of this I will simply state, the energy you CHOOSE to use is not of your choosing, for now- perhaps a fair market trade enviroment for energy- one that we can choose from- not one that is choosen for us. You know, The American way, open and fair competition.
