An aquarium full of electric eels could be a go.

Re: How can i have constant electricity on a boat

Our solution is variety and options. This includes shore power, 7KW diesel generator, solar photovoltaic array, wind generator, large AGM battery bank, and small inverter. In addition we are misers with use of 12VDC,- LED lights, efficient refrig/freezer, etc. I haven't seen any effective "Hydro power" as you mention. Multiple sources seems to be most effective

You should have plenty of room on your new 45' Hunter for a small nuclear reactor.

All trolls are nuclear scientists, right?

A VERY long shore power lead is a good idea, too

We have a couple of large solar panels, a wind generator, and the power from our alternator and we are always off the grid. We have four six volt batteries that are staying well charged. We are finding this more than sufficient as full time live aboard's.

Cheers, Kara

But you can't do a double circumnavigation that way. He's going to need a good 60,000 feet of cord!

He's got to keep that aquarium running!

Re: How can i have constant electricity on a boat

Use a battery to power a battery charger which can then charge the battery. Simple really!

Re: How can i have constant electricity on a boat

Well for heat ya could rub two sticks together! and for extra power ya could use a old world war 2 hand cranked telephone hooked to the batterys ! Ya could crank it while your laying on the bunk in your hunter !! Thats when your paying guests are sleeping of course !!

Can't you guys be serious for one dang minute!? Nuclear Reactors are a non-starter. I mean it was a reasonable idea until stupid hollywood came out with "Manhattan project" and ruined it for everybody.

The obvious solution is lasers. big lasers. And satellites.

Re: How can i have constant electricity on a boat

This problem has a simple solution.

Instead of using antifoul on your bottom have eight copper/iron cell pairs line it, they are immersed in an electrolyte so they will each produce 1.2 to 2 volts. Wire them together in series and you have a twelve+ volt battery, voila! Just keep away from lakes...

To supplement this you could also wire up a lightning rod to the system and go sailing in the Gulf of Mexico.


Have fun.
