The future drive for boats: MHD drive without propellor

[hartiberlin]

Have a look at this great
experiments.

This could be scalled up by using higher voltages and arc
discharges or BackEMF spikes from big coils.

I already posted some info here:

Here is the new video:

This is probably the future of boat drives in seawater.

Thanks for showing.
This concept might be rebuildet at home

Thanks for posting this video Stefan!  I always thought we needed superconductors for MHD....I guess not.  That looks like a lot of thrust even at that scale.  And the sea already has salt...right?  Excellent idea here.

Great solid state thruster and easy to replicate!

I wonder, would it also work in reverse as a saltwater flow to electricity generator?

If so it could be the basis for a great solid state wave power generator.

I think if the flow between the plates remains fairly laminar then it should work as a generator, I will try it soon.

The only downside, which shouldn't be flippantly overlooked, is the electrode and electrolyte chemical reactions, which could be a major pollution and toxicity issue for marine life if this form of propulsion was broadly introduced. If using non-inert electrodes, then they will disintegrate, and form various salts of the electrode metals suspended in the remaining electrolyte.

Even when using inert electrodes in sea water, to avoid electrode disintigration due to ionic reactions, there will still be generation of chlorine gas, which is highly toxic, (and is usually not formed when non-inert electrodes are used).

It seems there is always a price to pay for our actions, and it's not always payable with money. Let's hope the price of this possible technology is negligible.
It is a very interesting concept, as most simple concepts are.
