MHD {Magneto-Hydro-Dynamique} and research by Jean-Pierre Petit

Transport and new transport: energy, pollution, engine innovations, concept car, hybrid vehicles, prototypes, pollution control, emission standards, tax. not individual transport modes: transport, organization, carsharing or carpooling. Transport without or with less oil.

for that which is the mhd in the engine 4Temps I see several application, firstly according to which I understood one little controlled the flow of a fluid thus to accelerate or to slow down a gas as well as to make it turn.
So we can direct the flow of gas to either the spark plug or the (diesel) injector for favored either explosion or combustion.
Regarding the braking of a fluid could be placed an 2em floor of tubos (in series), braking the gas output of the 1 (hence increasing pressure) could be more easily recycled gas to pass in an 2e turbos.
Obviously I do not see this type of mounting on cars because the shots should be quite high but on large engines like boats or cogeneration engines the gain could be profitable.
When the gas turbine, we could significantly increase the efficiency of it, since it would allow to add a stage after recompression of the gas.

L'Arène de France show on UFOs
broadcast on France 2 on Wednesday 21 March 2007 to 22h30.
There are Jean-Pierre Small who will try to put one on the MHD ...

Disillusioned report of the sequence by JPP:
http://www.ufo-science.com/fr/news/arene_de_france.html

It begins.
But this is the second debate.

A very good example of MHD is the deflection of a trickle of water with a straw previously rubbed with wool

http://www.sciences.univ-nantes.fr/phys ... s/EauD.avi

What is crazy is that we consume no energy.

In this case, no current travels the fluid in motion (water) because it is already diamagnetic, and it is only necessary for a weak electrostatic charge.

What would happen with a larger load?

not quite true.

you used energy to create your static fields
your static field will eventually run out
and as a bonus you do not create any work

It's been a long time since the static fields were used to attract drops of paint from the other side of the room that is spray painted.

You're scheming Elephant!

indeed, the static field tends to disappear after a certain time and according to the relative humidity of the air:
The more humid the air, the faster the field disappears;
The water molecules present in the humid air "stick" to the "straw" and reduce the field.

Now visualize a sealed enclosure with dry air, a closed water tank and a network of very fine glass tube (capillary type), would not it be possible to raise the water up to the tank? hmm?

To verify: the efficiency of an electrostatic field through glass

I think you dream!

and it is not with that that we will operate my bath heater!

when with your dry air, it will not stay very long.

When the liquid touches the straw like on your film, neighbor, instead of static or MHD (?), It would not rather a phenomenon of adhesion rather?

Yes and I claim my status as a dreamer of high flight my dear,
when in dry air, if the water is cantoned in a closed tank, itself in a chamber with dry air, then this electrostatic charge will be permanent: IT IS CA QUEST GOOD! Image
remains to be seen if the water is still drawn through the glass, or some other material

Yes, and it hurts in the eye, neighbor!
MEUH NO!
The straw does not touch the water, go, try for yourself and you'll see

I do not have any more eye pain :D Image

Ok, I'll do that a little later, busy week ...

look at this diagram, I like this principle
