[Electric Boats] Re: New "battery" Tech

 

I agree with Victor. This technology seems more suited for propulsion directly rather than use the compressed air to spin an alternator/generator, and then use the resulting electricity to spin a drive shaft.

The description given said that 10 cylinders (I visualized scuba tanks) at 300bar represent 20Kw for 10 minutes, which translates to 3.3Kwh. Without many actual specifications, this system sounds bulky, complex and perhaps as heavy as regular AGM batteries. To be fair, the engineers were working towards solving different problems than we have with lead/acid energy storage, like the ability to stay "charged" for a decade in adverse conditions.

Fair winds,

It konsists of two 100liter carbo fiber tanks, with 300bar pressurised air. They had invented a new type of air motor. The plan was to produse a small car in France for the European market. The system should be suitable for boats too, if compressed air are available, or if you can produse it in an easy way.
