Idea - Energy recovery - Charging on board

[DISAR]

I just had an idea which is not totally CRAZY!

How about this. To have a charger inside the boat charging the batteries, and the charger to have power supply from the sea/water and speed of the boat. Kinetic energy transformed into electric.

I am a few years ahead...:rofl:

[ozzie-crawl]

been thinking about plutonium power cells myself dont tell the greenies :spy:

[DISAR]

As you have the cooling lines, there will be one for charging. Only the charger is missing

IN: water
OUT: +5 Amps, 2-...s

[Meniscus]

I'm thinking that the efficiency of the charger would have to be very high.

It seems to me that if you were interested in generating power to charge the batteries, I'd do it with the motor. A brushless motor is using power to turn a shaft. If you turned the shaft with something else, then you'd get power (generator). So, why not put another set of windings around the motor to generate power while you're consuming it to turn the shaft? Yes you would use more energy than it provides, but it may lead to some longer runtimes or additional power available for the run.

LOL!

[DISAR]

Or to put another motor between coupler and flex, which will be the generator. In commercial ships it is similar, some they have a shaft generator.

Wow, just think - you could remove the batteries and let the generator power the motor directly, and it would run forever!

I was thinking Caterpillar drive, stealthy, never hear it coming.........

I am not an electronics/electrics specialist but without the batteries you will have the boat steady in water forever.:beerchug:

I just give an idea and someone who is well involved in the business of these motors-escs-chargers may come up with something in the future. Honestly, the thinking is correct the technology is missing. USA is far beyond in technology and we should see someting like that

[cyberhoops]

I like the creative thinking, but we are going to need some serious technology advances for this one.

We have a water towed generator on our Hunter 34 sailboat for crusiing. In this case the generator is able to produce about 12 amps to trickle charge the on-board batteries and it is only a small drag on the 3 ton sailboat. But it would not scale down very well to FE boats. Even at 80% efficiency the drag induced to turn even a small generator would be killer.

A generator and motor are very similar - and the amount of force needed to turn the shaft of a generator is much like trying to turn the shaft on one of our brushless motors.

What you are trying to achieve is Perpetual Motion where a motor drives a generator which drives the motor but still has extra power to drive a load. In this case your prop. A lot of wizards have tried but it hasn't been done yet.
A couple of Aussies have made a Zero Point Generator. Which basically produces energy from the magnetic ether all around us. Old Nickola Tesla was going to give the world free energy using his discoveries & principals until the "powers that be"shut him down. Just like they've shut these guys down.

Here's what you want just slightly smaller.

Do a google on Nikola Tesla... Electromagnetic generators.
And ...Scalar Technology.
Also... have a look at some of the videos on the sidebar of the one posted above. Like this one.

You'll be lost in there for a long time surfing around if you are really interested.

Paul, did you see my picture album on Tesla? http://forums.offshoreelectrics.com/album.php?albumid=34

I'll have to check out the links provided when I'm not at work and have time to read in depth, but what you explained is exactly what I was trying to get at.

[DISAR]

Very nice info, so there is "something" actually but for well "unknown" reasons it cannot be further developped. If it is free energy what the power and oil companies are going to do?

[egneg]

All that is needed is a flux capacitor!

LMAO! I knew I could count on you Egneg! :laugh: :thumbup1:

Regardelss of what anyone thinks, immutable physical laws deny the possibility of true perpetual motion. You would be $$$ and time ahead to simply buy packs with a larger capacity, or run 4P.

Yep, just for you I do have a real nice bridge for sale......

Just wait on the fuel cell tech to develope a bit more. Then we can enjoy hours of run time... for the low cost of just a couple limbs. Then again that was the attitude toward lipo back in the day. It all gets some what affordable.

[Meniscus]

True, we have a local guy that's working on fuel cell cars and will be applying to boats soon. We'll have to see how that works out. I just can't figure out what he's going to do with the heat!

I 've met a guy recently who wanted advise on building a "machinery" or something like that, which takes advantage of the Archimede's law of buoyancy, and it can rotate in water forever by itself hence producing electrical energy in the end.
I tried to help but the idea is really crazy.:thumbsdown:

[Blackjack-sven]

If you think about perpetual motion and what it means, free energy for life will never happen as an object needs to produce energy without any friction at all and transfer this energy to something that is not attached to it, for if it is attached to it it will produce friction causing the free moving object to slow down over time even if it is .0000000000001 of a trillionth of decade. The theory of producing power while driving anything is only a way to increase drive time without adding too much more weight to the vehicle. And until then I think some liquid naquata coupled to a fusion chamber will have to do.

Hi Meniscus.
Sorry I missed your other post.
Being an electrician, Tesla is a bit of a hero of mine. He discovered most of the principals of electrical & electromagnetic energy that we use today. He invented transformers, coils, 3 phase A/C generators & motors, A/C power transmission & more. He died with over 2000 patents to his name. Edison stole his ideas. Marconi used 5 of his patents to transmit the first radio message. Tesla had already done that & was working on wireless electricity generation & transmission.
It's a sad story what the scientific community did to the most brilliant mind of the age.
Here's something by Tom Bearden that may be of interest to those that would like to know how electricity really works.

You'll have to click on to Tom Beardens' main file.
And then click onto "How Electricity Really Works."
Read through the rest of the site too for some fascinating info. It's all to do with Scalar Technology.

Cheers.
Paul.
