Yeah, let’s nip the Zero Point Energy and perpetual motion stuff in the bud now on this thread…any substantive discussion in that area risks wasting your time in posting and losing posting privileges. This group isn’t the forum for those discussions.
Thanks.

Subject: Re: [Electric Boats] Re: Charging battery bank while underway..
Getting "more out than is put in" violates the laws of thermodynamics. I'd be interested in reading about it though if you can point me to the article. Perhaps there are substantial efficiencies which can be gained by incorporating whatever ideas the article is putting forth.

I have not heard anything new tech yet.
Buy a gas outboard is not my idea of a good solution.
I am not to fond of the gas generator either, I do like the solar idea but still wanting something new and outside the box type thinking.
I once read an article on an elector-magnetic generator, basically using coils and transformers to overlap the electric energy field to multiply the input energy and get more out than is put in. I know it is untested in the field but it is out there. There is a guy up in Canada that has made a hydrogen generator for his boat... a little pricey but no moving parts and no pollution at all.
I am also working on some zero-point energy devices myself to put into my boat so I can recharge my batteries e-route. If you think about it a little bit... most cruise ships and trains run a diesel generator to power their electric drive system so it is possible... we just need to shrink down that technology and make it affordable.

Just a thought, depending on your budget a simpler solution to your needs might be one of the Torqueedo products. I use one for my dinghy and it would definitely push a boat of the size you're thinking well past the range you've got in mind. All up it weighs around 35lbs, lithium battery included, or get one of the models which are powered by your own batteries and then you can charge underway using the method of your choice and increase range with a larger battery bank as needed.

Of course, I can charge at the dock/campsite/lock with an onboard charger and generator, but here's the question:

A 4 bank charger (15 amps x 4) would put over 800 watts into the batteries in bulk charge. That would certainly be enough to continue cruising with my canoe.
