Re: Alternative to Solar

In order to understand the market needs one would need to first define the market. If that is recreational sail (not power) boaters, have your friends yet found out how many boats in each size range...

Re: Alternative to Solar

I once read about an engineer crossing the Atlantic who used a larger copy of the mechanism in a self winding watch to charge his batteries. It was so powerful that he had to disconnect it most of...

Re: Alternative to Solar

I think it would be an awesome device to incorporate into a sailboat design intended to have an electric motor. Going green all the way. Then you could make it really heavy and place it close to the...

Re: Alternative to Solar

" of course the average output of 36Ah "
But 36 Ah is not an output or output rate. It is just gibberish unless you say "36Ah at 14 volts over a 24 hour period" or something similar.

Output...

Re: Alternative to Solar

Here's an inherent difficulty of tidal generators: you know how a tide chart is basically a sine wave, showing min/max peaks every six hours? There's another sinusoidal graph about 90 degrees out of...

Ive got a 38' Morgan 383 i run three 100 watt solar panels and a 300 watt wind. between them i run everything on my boat well. Now i have looked in to a pull behind for power but the consensus i...

Re: Alternative to Solar

It's true that we try to find the calmest spot to anchor but in my experience, those spots are quite often not in the plan. Unfortunately when traveling longer distances, it's a case of choosing the...

Re: Alternative to Solar

Yes maybe you're right but the fact is that a kinetic watch uses absolutely minute amounts of electricity. Multiply the generated power by 1000 and that technology will probably provide enough power...

Re: Alternative to Solar

I've always wondered why the East River around Hell Gate or Woods Hole have not been harnessed somehow to generate electricity. Wind blows sometimes, tide always runs. In Woods, it would seem better...

Re: Alternative to Solar

Considering the fact of being at anchor, I wonder if the pull of the boat against the anchor could somehow be harnessed as a boat continually swings in the wind. Considering the tremendous current...

Re: Alternative to Solar

Once again, we're stuck with the physics of the thing. Lets imagine a 3kt tidal current at anchorage (that's quite a lot) and pretend our collapsible water wheel is 3' in diameter and perfectly...

Re: Alternative to Solar

I'm a big fan of Edison batteries. They last forever. And as long as you don't overcharge them, are perfectly safe. (IIRC, you can overcharge them 25% - and some people do, on purpose -- but more...

Re: Alternative to Solar

This effectively removes the benefit for nearly all cruisers. Such a device would generate 1.6Wh per pound, each day. My solar panels give me 2,800Wh on 5 hours of sunshine. And since I cruise in...

Re: Alternative to Solar

No question about it - juice storage capacity is just as important as charging ability. Seems like most sailboats are not designed to carry a lot of batteries weight where it is most beneficial (and...
