1000 Ampere magnetohydrodynamic (MHD) liquid metal pump demonstrates Lorentz force in laboratory model. The following setup is an MHD conduction pump which uses magnetic field of permanent magnet and DC current to create perpendicular Lorentz force that drives the flow.

Thanks for the great video about this fascinating property of electromagnetism "engage the caterpillar drive"

@MitzpatrickFitzsimmons 2 года назад

Wow.. just excellent! I am compelled to say this is on the cusp of where science meets art.

Fantastic!

Awesome 😎👍 😊

Does exist a video of AC resonant MHD drive and is its efficiency greatly increased due to not causing electrolysis to happen?

@kevinkostlan7934 Год назад

I want to stick my hand in it! A hand has so much more resistance than the non-toxic GaInSn metal that the current will harmlessly flow around.

At 1 volt it would also have a hard time actually breaking past the skin layer on your hand.

Cool

Can v x B electric field produce static differential charge concentration in solid conductor?

@pablo-3987 2 года назад

Nice video, Thank you for sharing. Would you suggest an alternative conductive fluid, cheaper and non toxic, even if less conductive?

@MHDTechnologyLaboratory 2 года назад

Saltwater or acid solution would be the cheapest from electrolytes. They of course will be 4-5 magnitudes less conductive than metals. If you have more resources you can choose from low melting temperature metals like: lead, tin, bismuth and their eutectic alloys. You will have to melt them, however, they will cost about ten times less than this.

@martyschrader Год назад

The injection of that much electrical power must have heated the metal up considerably, did it not? I thought the idea was to extract heat, not inject more of it into the system.

@MHDTechnologyLaboratory 11 месяцев назад

Not really, because the voltage is low and resistance of the metal is small. Maximum applied current was 1000 amperes using voltage of around 1 V, making total power of ~ 1000 W. Some parts of electrical connections were getting warm, though.

@madjimms 11 месяцев назад

do this in normal air with tens of millions of volts and you can go REALLY fast.

I am building a theory around this being the queens chamber in the great pyramid of Egypt.

@nakrul987 Год назад

can you make a fountain?

@MHDTechnologyLaboratory 11 месяцев назад

Sure, why not.

Doesn't your metal get hot at that amperage

@AltumNovo 2 года назад

The current results from the macro flow of the liquid rather than just charge moving through it I think

@MHDTechnologyLaboratory 2 года назад

Not really. The wires have more ressitance than liquid metal part of circuit so only the cables got warm. And even that happened only at highest amperage.

@phonotical 2 года назад

@@MHDTechnologyLaboratory oh so, in the video you were only running at low power?...

@MHDTechnologyLaboratory 2 года назад

Not really. Some clips are at 1000 amperes, some are at 500. After 1000 ampere runs we let cables cool down.

Please help me. I want liguid gold from lead.

@philipp594 10 месяцев назад

Aren't most liquids that conduct electricity very distructive to other components? Galium infuses into pretty much everything and salt water will corrode most metals.
