Does it exist? No.

Is it possible? It seems unlikely.

We got, the sun, we just need a mini version of that

Oh, of course. Why did no one think of that before?

Because it could get pulled in by gravity? Building a self sustainable "sun" on earth is a dangerous thing. It is also the path to unlimited energy, we can have two sun, if not three. It is just a bunch of gas as I've heard from taxi driver. It is not a solid planet

Star is doing fusion just because of pressure caused by outer layers of the star. If this pressure is not enough, you have just cloud of gas in cosmic space.

Human made fusion reactors have to simulate this pressure using different methods than gravity. e.g. powerful superconducting electromagnets, and concentrated lasers are used to do it.

But energy produced by fusion does not compensate energy required to cool down superconducting electromagnets and lasers, yet.

I see, that makes sense, with the electromagnet part. And the pressure to keep the gas together. Maybe they could out produce enough energy, we'll see

There have been attempts to build fusion power generators for decades. We are not much closer. It is just really hard.

Pretty glaring emission...

It's only 20 years away!

Probably doesn't require its own thread, but here is a story on China's work to build a fusion reactor: http://www.bbc.com/news/blogs-china-blog-43792655
