    This should be one step closer to making cheap economically viable biofuels from cheap biomass (such as grass ) closer to reality by economically separating out the lignin in the biomass that would otherwise normally gets in the way of turning the biomass into biofuel;

    It's funny, all these competing technologies, wonder which one will win? H2? Methane? Electric? For transport.

    Don't know which will become dominant...
    But I suspect a combination of all of the above for different applications.

    I am not sure about the medium run but in the VERY long run; electric for everything except aircraft. And magnesium-sulfur batteries would be the battery of choice for virtually all electric vehicles despite the fact that there is currently virtually no research into magnesium-sulfur batteries.

    VERY long term nuclear is probably the answer.

    Solid state aneutronic fusion is showing promise for battery like power applications
    if you are looking really long distance into the future.

    On site direct power generation will always beat energy storage and transmission
    for efficiency.

    I don't know why you would think that. Why not solar and wind (among other renewables ) combined with a supergrid and off-the-grid storage to completely compensate for solar and wind being fickle?

    how did you conclude this?
    If you are still talking nuclear here, wouldn’t it be rather inconvenient if not impractical to, say, have a car powered directly by its own nuclear reactor?

    A big worry there would be terrorists opening new junkyards.

    Yikes! Any psychopathic moron in the world will be able to make a nuke from junk!
