Hi, I'm curious, how would I create an electric field to a noble gas in a sealed vacuum and how much energy is needed to create plasma from air? You see, I'm building something, and theorizing. A plasma theory that uses the simple concept of convection, the hot air will make the craft rise, and then the sudden cooling to descend. For one, this is a very early topic I started last year about 3 months ago. I have done alot of research so far, but school got in the way so there isn't as much as I'd like to know. The inspiration from when one day, I thought about Halo 4 and how much I wanted to play it. Then I started reminiscing about it and I remember some kind of purple electricity from the bottom of covenant hovercrafts. Perhaps this theory will be like that. I don't expect much excitement from this, but it would be cool to make a plasma-based hovercraft. Also, It would be nice if someone could lead me to a page all about plasma going down to the atom, subatomic particles, and energy itself, and what should I use/do to create the plasma. This concept is practically a hot air balloon, but it isn't. It's super heated plasma from the bottom of a hovercraft. Thanks in advance for all support!
