I have set myself a goal of building a fusor in 2 yrs. I am looking for any help, but especially I am looking for book suggestions, websites, articles, everything I need to know​ to build a fusor. I hav2 always been interested in physics, but I need a solid base not just a patchy and vague sort of understanding. Even if you can't give me any concrete suggestions, I would appreciate a detailed outlining of all the fields necessary. E.g, high voltage, vacuum, plasma, electromagnetic fields... these are just a few broad ones, i would really appreciate more detail if possible.

Thank you all very much in advance!​

I understand how the the solar system sort of balances with itself and how we all orbit the sun (why we dont fall out of solar system or away from sun), but what keeps earth at its distance? How does earth's orbit not decay and we wind up falling into the sun?
