UMN energy conversion

In the lab, University of Minnesota researchers show how a new multiferroic material they created begins as a non-magnetic material then suddenly becomes strongly magnetic as the piece of copper below is heated a small amount. When this happens, it jumps over to a permanent magnet. This demonstration represents the direct conversion of heat to kinetic energy.

I hated the first half of this video, but it started to grow on me around the second act.

[Phil Schaf]

it’s surely funny how a small jumping flake of metal completely stuns me. great!

[Seth MacFarlane]

At 0:04 is where it really gets interesting.Your welcome

[Tom Wardrop]

I liked the part where the metal flake moved.

What temperature is this at?

[Angel Gdo]

Some of this heat energy is lost in a process called hysteresis.

I had not much readed about this still so i dont know details. Maybe you readed more and as physic you can answer me some doubts if you want. 1 - Do you think this metal can replace a classic turbine transforming traditionally heating into electricity? in this process you loose more than 50% of energy i think. 2 - Maybe loosing less energy? 3 - and for big amounts (Big metal, scalability) like in a nuclear central powers of MW? 4 - Metal must be replaced or infinite uses? Tks Lot

WOW NO CHANCE REALLY SUPER I HEARTY WISES WE ARE WAITING FOR THIS TO CAME OUT

That "incandescent piece of metal" is yellow-orange because it's copper.

Ну и как много энергии при этом выделится?

[prestorjon]

wow, just wow. From watching the video though, it does look like it takes quite a bit of heat, eventhough their release said that they hoped it could be incorporated into a hybrid car's exhaust... significantly less than the incandesant piece of metal they have it on... of course it's probably a deficit in my science-fu.

About time we stopped boiling water in a bucket via the means of lumping together the most heaviest metals around.

I'll take two L-sized suits with a built-in rectifier, please.
