    Hi Rich, thanks for pointing out the energy balance paragraph. I had to read
    that rapidly before work this morning.

    >>In this respect, the
    >>formation of a mixture of hydrogen and alkanes from aqueous-phase
    >>reforming of glucose, as accomplished in the present study, is
    >>**essentially neutral energetically**, and little additional energy is

    >>suitable fuel cell; this would allow the use of biomass-derived
    >energy to

    >>with high yields to renewable energy. [emphasis mine]

    I would bet, that by the time you add that little item called TRANSPORTATION
    you would turn this into a negative. One must spend energy to distribute
    this fuel so that I can put it in my tank where I life.


    for lots of creation/evolution information
