Sugar/Starch To Hydrogen For Vehicles

Posted on Monday, May 28 at 10:33 by drcaleb
“We need a simple way to store and carry hydrogen energy and a simple process to produce hydrogen, said Y.H. Percival Zhang, assistant professor of biological systems engineering at Virginia Tech. Using synthetic biology approaches, Zhang and colleagues Barbara R. Evans and Jonathan R. Mielenz of ORNL, and Robert C. Hopkins and Michael W.W. Adams of the University of Georgia, are using a combination of 13 enzymes never found together in nature to completely convert polysaccharides (C6H10O5) and water into hydrogen when and where that form of energy is needed. This “synthetic enzymatic pathway” research appears in the May 23 issue of PLoS ONE, the online, open-access journal from the Public Library of Science. http://www.vtnews.vt.edu/story.php?relyear=2007&itemno=300 [Proofreader's note: this article was edited for spelling and typos on May 30, 2007]

    Hydrogen from biomass is every bit the dead end that ethanol is when it comes to supplying the fuel needed to keep our society running, even at reduced levels, and for exactly the same reasons.

    Food vs Fuel.

    There's only one source that can provide the amount of hydrogen required: the oceans.

    As a type II diabetic, I can say with conviction that getting the starch out of our food and used for fuel is in everybodys' best interests.

    Hydrogen can now be generated from an Aluminum/Gallium alloy using only plain water. Another step in the right direction.

    starch is found in every plant grown by man as food.

    food vs fuel.

    My point stands.

    Carbohydrates are responsible for the surge in type II diabetes, and not every food man grows have Carbs or Starch in them. Asparagus is but one example. Many others have more fibre than starch, negating the starch.

    Starch, Sugar, Carbs are all added to food, when they don't need to be there. Starches do not need to be food, they can be fuel. My point stands too.

    Your point was to use the oceans as fuel? How?

    When you have hundreds of millions who barely get enough to eat, those starches in grains and rice, become what keeps them alive for another day.

    Our over starched First World diet doesn't reflect the reality faced by hundreds of millions.

    I,for one, will never be in favour of feeding vehicles rather than people.


    In addressing your second question:

    Simple, you use wave generated electricity to electrolyze water, breaking it down into it's two components: hydrogen and oxygen.

    Hydrogen that would be used as fuel, thus leaving biomass out of the equation.

    Wave generation on that scale would also lower reliance on gas/coal fired electrical plants for providing electrical power for home/industrial use, and perhaps render large scale nuclear unnecessary in the vast majority of applications.

    It's an excellent plan, but it will take quite a long time to come to fruition.

    I have no problem making our fat 1st world nation a little slimmer, if we want to continue our energy consumption at the same rate.

    It doesn't have to impact the 3rd world.

    To paraphrase your statement:
    "There's only one source that can provide the amount of food required: the oceans."

    Not if nations keep strip mining it of life the way they are currently.

    Do a Google on "bottom trawling" and it's effects on marine environments.

    Got me on that one......

    So, the plan is to "mine" the oceans of all useable protein, until they are all dead - then break down the (now useless) water into hydrogen and oxygen (which we will need because having wrecked the oceans we have cut off a major oxygen supply), and finally the corporations will have one of their fondest dreams come true - to be able to sell us the very air that we breathe.............Clever! Diabolical! BWAHAHAHA!

    I'd support this idea if someone can show me where the poor come out on top when competing with the energy giants.

    Ethanol, starch etc etc all pretty much equal a shift of food production. While we produce more than we need in the West, attitudes of greed and lust prevent it getting to those that need it. And in those same places where starvation is already a daily fact food will become even scarcer and more expensive as it is diverted to energy production.

    We win, and they continue to lose. Everything changes, yet stays the same.

    I see a trend here; it would seem that most people do not care about whether
    we can have more, etc etc. Our priority must be feed the world first. I agree.
    Once we ensure that every single person on the planet has enough to eat to
    do more than just keep them alive, then we can work on the other problems,
    concerns, wants,desires. One thing I have learned is, its not that the rich
    want more to satisfy their greed, because once you have millions, what more
    can you do with billions or trillions? No it is simple, they need it, because if
    they have it then the rest of us don't. That is the only reason for them to do
    what they are doing. Am I right? Is that the primary argument here?

    So finding alternatives for fuel, so that we can get to work for them, buy from
    them, etc etc, doesn't seem nearly as important as finding ways to feed the
    world! And actually when you think about it, it isn't even that, it is finding
    ways to stop people from preventing others from feeding themselves. Finding
    ways to stop the control of agriculture land, poisoning the water supplies etc.
    That is what I think the argument is over the use of agriculture land for fuel,
    it will be just another monopoly controlled by the few, used for fuel and there
    will be nothing left for the people to grow food. It is happening already in
    some countries due to their land being controlled by corporations.

    *Shakes head in utter disbelief....*

    I cannot honestly believe you're serious.

    Maybe I should just take up drinking.

    If I were the Premier Danny Williams of Newfoundland , I would develop the Lower Church Hill and utilize it to manufacture hydrogen. Construct special container that would house the hydrogen,which would be used to run electric generators. These containers would be transported by ship, built in Nfl. <br />
    <br />
    This could be a very new industry for the good people of Newfoundland, they could start a complete industry from the Lower Church Hill, from water to electric generators.<br />
    <br />
    These generator terminals could be located all along the Eastern seaboard, from Newfoundland to Florida. <br />

    If it's okay with everyone, my share of potatoes can be used for the starch they produce. Potatoes can be planted in the most adverse conditions and the scars and sprouts would not change the amount of starch they produce.
    Harper has already given BC a gift to build a Hydrogen ready highway. We all danced in the streets, to know that all those Hydrogen vehicles can now get fuel all the way to California.
