    Replace Diesel Generator by turbine

    For the first application (ferry in toronto) a quiet and green alternative to the huge battery bank is maybee a mcro turbine :

    Since you will have to heat the boat some part of the year, you could use that microturbine to do so and have it charge your battery bank.

    The weigth of the smaler turbine (off grid) is more than 500 kg.
    This limit the marine applications but the product is great :
    Electricity generator oil free and almost maintenance free...:)

    Capstone mini-turbine

    This company is the same one that was employed to provide the small turbine/generator for the Super Flywheel Patriot LeMan's Race Car that Chrysler was working on:

    The Patriot hybrid-electric racing car
    Chrysler designed and built a hybrid-electric, turbine-powered, liquid natural gas-fueled racing car for racing; the company said it could reach 200 mph for short durations, with competitive handling. The powertrain included a two-turbine alternator, an ultra-high-speed flywheel and an electric traction motor. All components were water-cooled.

    The traction engine was a four-pole, three-phase, 525-volt AC induction motor, weighing 143 pounds, with a maximum speed of 24,000 rpm; it had an aluminum housing, was lubricated by oil, and had an 8:1 motor to final drive ratio.

    The turbo-alternator was a compoounded twin-spool turbine with two alternators, fuled by natural gas, with a 100,000 rpm high speed and 50,000 rpm low speed; an intercooler was placed between the low and high speed compressors. A single point combuster was used; the alternators were three-phase AC induction. The whole thing weighed 186 pounds and was water-cooled; materials used included composites, ceramics, titanium, and stainless steel.


    I brought up this 'flywheel energy storage' subject on several postings here

    Tri-Engine Hybrid

    Do you know of anyone who has used your electric engines as an addition to an existing gas/diesel engine?

    The purpose being to use the gas/diesel engine to get up to planing speed and use twin electric engines to maintain the plaining speed. My understanding is that it takes less than half the power to maintain planing speed than to get to planing speed.

    You could also use the electric engines as "re-generators" when running on the gas/diesel engine. Hopefully doing away the the need for a diesel generator.

    Perhaps this could work on a smaller catamaran like the 23' C-Dory.

    New Company, New Subject Thread

    I was going to just make an additional reply to this older subject thread, but it appears to have strayed off subject in several instances, so I thought a new begining was applicable considering the fellow who really brought this relatively new technology to the yachtng scene has also a new begining.

    And then his new website:
    E Motion Hybrids

    New Subject Thread

    Hi-Jacked Subject Thread

    Well forget that idea. That new subject thread I started got hi-jacked.


    There is an interesting new article out in ProBoat magazine #142, Apr/May 2013. Eric Sponberg posted an interesting synopsis of that article over here.

    Yobarnacle, if you are replying to threads jus so you get notyfied of new replies, there is a better way. On top of the page there is a button called thread tools. Under it you can choose subscribe. And later if you stop being interested you can unsuscribe.
