What stops us from creating a nuclear fusion reactor as we already have the hydrogen bomb working on the same principle of fusion?


I have been out of physics for some time now since my childhood, so please bear with me if the question below feels too novice.


I grew up with the understanding that the nuclear fusion reaction is still a dream of many people as it's a source of clean energy without the side effects of nuclear waste as we observe in nuclear fission.


Now recently I was just checking the principle on which the hydrogen bomb works, and I was shocked that it uses nuclear fusion to generate all that energy. This contradicted my understanding that nuclear fusion is not a dream but it actually is a reality.


So if we already achieved nuclear fusion why can't we create a nuclear fusion reactor out of it to generate all the power we need? Also why can't we have the small scale fusion reaction on Jupiter (as mentioned in my other question) that can help us take over the outer planets of solar system.



Also I just wanted to know if we can continue this fusion reaction to generate precious heavy metals – is it possible?
