I was looking at a candle that I lit, just watching the flames dance on the wick and for some reason started comparing it to a lightsaber. The fire on a candle sits on a wick, just as the blade of a lightsaber sits on its hilt. However, the flame is free-flowing while the lightsaber is a straight laser. Flames go a certain distance based on heat, but today's lasers continue to travel until something stops it. Right now I feel pretty stupid thinking about something that doesn't exist, and I'm no scientific inventor but I like to dream. And now I'm not sure where I'm going with this...if you have any input or feel like talking about your own concept ideas feel free.
