Helical engine

Okay kiddo, so imagine a toy car. It moves forward because there's a little motor inside that makes the wheels spin. Well, scientists are working on something called a helical engine that works kind of like that toy car, but much bigger and more complex.

You know how when you screw in a light bulb, you turn the screw around and around? That's called a helix, and it looks like a spiral. Now imagine millions of those helixes all fitted together in a big engine. When the engine runs, it creates a twisting motion that pushes the engine forward. This is how the helical engine works.

But why is this a big deal? Well, regular engines use fuel like gasoline to make them go, and that can be bad for the environment. The helical engine, on the other hand, can use other sources of energy like nuclear power. Plus, it's much more efficient, which means it can go farther and faster with less energy.

Scientists are still working on perfecting the helical engine, but if they succeed, it could change the way we travel and power our machines. Pretty cool, huh?
