    Very interesting. He is now 84 years old and who knows he may see his invention finally go into production!

    The interesting bit for me was his attention to the porting of the intakes, in producing more power from the engine.

    For me it is more like can it be brought to significant production numbers to save a fading industry?
    Seems like wishful thinking.I believe battery powered will be the wave of the future.We have seen huge improvements in the last 20 years.
