00:00This is Nitinol, also known as Shape Memory Alloy.

00:03It is an alloy made of Nickel and Titanium.

00:06It is called Shape Memory Alloy because it does not forget its shape.

00:10You can twist it however you want.

00:12But when heat is provided to it, it takes back its shape just like it was before.

00:17Like when this spring-shaped wire was deformed,

00:20and when heat was provided, it came back to its spring shape.

00:24And along with it, a metallic muscle was formed, which is lifting this stone.

00:28But why provide heat from outside every time?

00:31You can provide electricity to it and use it.

00:33Now look at this.

00:34Two things are happening here, which is making it spin on its own.

00:38The lower part is in contact with hot water,

00:40which is causing the upper wire to bend due to the cold area.

00:45As soon as it comes in contact with the heat below, the wire straightens.

00:48And this cycle is going on.

00:50By the way, yes, you are imagining it right.

00:52This can be a new way to run a generator, and it is absolutely possible.
