    The IC engine equivalent of a BSOD is...running out of gas,ignition failure,throwing a rod,dropping a valve etc.etc.etc.

    The nice thing about H is tat ican be trickle charged form a solar setup to fllup a tank a day from home. To wipe out petrol stations in general I reckon. Honda have been working on such a home setup.
    H2 is a very diffcult fuel to burn in an engine -it wants to explode all the time and at all mixture ratios.
    Combustion chamber temperature control is critical.
    Pivotal have even gone as far as water cooling their "pistons":

    don't think any engineers would be stupid enough to run windows on an electric bike.

    Depends what kind of engine too - there has been some amazing work done on Sterling engines lately...
    I believe that combustionproblmes can be relatively easily fixed by tweaking, as opposed to innovation. The advances in direct injection engines, and high speed engine management by computers will be able to deal with that easily enough.. (IMO)

    I think most engineers are already reluctant to run windows on a computer!

    oh contraere, most engineering design programs don't (or are a complete prick to make work) run on any other OS.

    And Bogan, I'm pretty sure that even if the design programs run in windows, much new technology in terms of computers in vehicles, mechatronics etc run under Linux?

    All very interesting. However one person says H2 has a lower 'energy density' than petrol, one says the opposite. I'm lazy today and can't be bothered googling it, so what's the answer? Or does it vary?

    Never tried before. Off to the garage now, I'll report back soon.

    Remember the 'pop' of a test tube of Hydrogen in high school? Just bigger.

    It's a long while back now but yes I do remember Mr Jansen showing us that.
