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 Link to comment Share on other sites More sharing options...

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. Link to comment Share on other sites More sharing options...

And the pressure to keep the gas together. Maybe they could out produce enough energy, we'll see Link to comment Share on other sites More sharing options...
Strange Posted April 2, 2018 Share Posted April 2, 2018 There have been attempts to build fusion power generators for decades. We are not much closer. It is just really hard. https://en.wikipedia.org/wiki/Tokamak https://en.wikipedia.org/wiki/ITER Link to comment Share on other sites More sharing options...

Strange Posted April 18, 2018 Share Posted April 18, 2018 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 Link to comment Share on other sites More sharing options...
