Question

The nuclear fusion could not be used as an experimental and control source of energy till now .
why?

Answer 1

Answer:

In theory, it's possible to shoot some energy at hydrogen and get even more energy back. The process is called thermonuclear fusion, and if we could ever get fusion power to work — a big if — we'd never have to worry about our energy problems again.

It's not a completely crazy notion. Nuclear fusion already takes place in the sun's core, after all. And the promise of fusion power has led researchers to try their best for decades upon decades. Occasionally, they even make some advances — as happened this past winter, when a group of scientists got closer to fusion power than they ever had before.

Trouble is, the scientific and technical hurdles ahead are still enormous — in fact, we still don't have a full grasp on what all the hurdles might be. Still, the potential pay-off is so massive that countries have sunk billions and billions of dollars into fusion research.

So here's a guide to how far humanity has come on thermonuclear fusion — and how far we still have to go.

Thermonuclear fusion is the process that occurs when two atoms combine to make a larger atom, creating a whole lot of energy.

Fusion already happens naturally in stars — including the sun — when intense pressure and heat fuse hydrogen atoms together, generating helium and energy. This process is what powers the sun and makes it so hot and bright. Researchers who work on fusion energy are essentially trying to make tiny stars here on Earth.
