    I thought I would make reference to this forum dicussion occurring at the YachtForum site for those who might find the subject of interest and care to contribute to it.

    Hi all,
    This reply is a bit aside from the main "diesel-electric" discussions, but it fits well within the alternative-drive philosophy.

    With a small team of thermo-dynamic engineers we're currently working on an "air-only" or "air-electric" drive solution.

    In the "air-only" solution - which we will first apply to catamarans, because they're much less power-hungry - 2 compressed-air engines will drive the props via shafts. The engines run since more than 5 years in a car, a genset, a mini-tractor, etc. We plan to install 2 x 25kw engines in a 40-45 ft cat by next summer (in Europe).

    In the "air-electric" solution the main drive will come from electric motors, with electricity being supplied by one (or more) compressed-air gensets. This solution will apply to larger vessels, first stage will be a 65 ft cat.

    In both configurations range will be increased by heating the compressed air between tank and engine with an external heater-burner, using any kind of fuel, at a rate of 2-3 liters / 24 hours.
