I came across of this web site, where a new technology is being implemented. Although, it is for trucks only for now, but the company is actively pursuing other options and vehicles for their technology. I understand that to move this concept to yachts would require lot of R&D, but we just never know. I wrote to them and their answer was that it could be installed in vessels, as well. So, take a look, read the technical part, think about the torque they create, and tell me, if this is really crazy?
