The systems do work. They are quiet, don't vibrate like a diesel and are much less harsh on the environment. If you do a bit of digging, you'll find quite a few craft that rely on electric engines as their sole means of propulsion. I think that if we took all of the home-built, the experimental and the commercially-built units together, we'd find there are a couple of thousand electric boats out there.
The problem is the energy storage system. I think that the interest in the field is growing quickly, and with the price of oil being what it is, a lot of very good research is going to be done in this are over the next decade.
I'm thinking we'll all be using electric in fifteen years.
Yes. I agree. Thank you, no one seams to pay attention to anyone else. They may not be perfect, but storage tech is changing daily.
