ION ENGINE

Study

Among rocket technologies, there's an ion engine.

It's an engine that uses 10 times less fuel than a chemical rocket, but why don't you use an ion engine in real life even though it's so efficient?

pu1. Ion engines consume less fuel, but they are very weak. The size of the force is like lifting a piece of paper. It's hard to escape the gravity of the earth
Nevertheless, the reason why it can be used in rockets is because it is weightless in space. Because in zero gravity, if you keep applying even a weak force, you'll get faster and faster
