    I used to work at a fast food burger place and one day, this other employee was talking to the manager in the kitchen. He leaned against the grill putting his hand on it for balance (I know dumb right?). anyway, he laid his hand on the hot grill and burned it real bad. The manager laughed about it too. So I don't know about putting your hand through that lightsaber blade. Personally, I think lightsabers are cool, but I would rather have a laser or plasma GUN (rifle or pistol). That would be a lot more practical AND realistic to build an effective one. Though I can't see someone building a decent one any time in the next 120 years.

    Cool, have you looked into elongated toroidal plasma fields? Much like onions the more layers you have the more dense the blade. If it behaves like a tornado then you could improve plasma density. Another cool idea would to power it with a space time Crystal. There is a substance similar to wootz steel if embedded with the right isotopes would create a lot of energy. Similar to a nuclear battery. Providing you can get the carbide in the steel to resonate. Then you would have a means to preheat the plasma with the energy it provides. Another way is understanding the subatomic bonding. all a lightsaber would be is a device that splits that bound. But it’s questionable to how efficiently it would do this. I’m not all key up on the math side but I’d say that would be a way to go. Considering all matter and energy is a spectrum. If done right you might be able to recreate Luke’s lightsaber. The way I see it there’s a a few core components power cells, constrictor coils, and something that can create vortices in a medium in which to create plasma. The medium could even be subatomic in nature. Heavy ion bombardment generally would be an approach to consider. Most cutters don’t cut, they push things out of the way with in specific vertices. So the real question, how would this be achieved within a hand held device? Thats where it’s non to clear where to go? I’d say Yes it could be done ,but it’s a question of how risky it would be? Thinking about it if using glow in the dark elements. you might even be able to colour the plasma to get various shades of lightsabers. I’d say go for the coffee bean approach . so if the hilt was the bottom of the field the blade would simply sit between the emerging field lines. Hey presto a lightsaber. I’m sure haven’t got it all, but I think a it’s a fair deal. Over to you. An good luck! Glad the hand survived. I love to see you next creations.
