The lightsabers used by the Jedi and Sith in the Star Wars universe are built on technologies that are beyond our reach. But this does not mean that we cannot do something similar. Engineer and blogger James Hobson, better known by the pseudonym Haxmith, has designed the most advanced version of such a weapon - his blade is in all seriousness capable of melting steel.
Haxmith has long been into the lightsaber theme and has made replicas of Kylo Ren's proto-sword and triple-beam sword in the past. Alas, these were only beautiful imitations, in which two main principles were not observed. First, the lightsaber blade is dynamic, it is formed before the fight and disappears when the weapon is disabled. Secondly, the blade is material, but it consists of a stream of energy with a high temperature.
The main difficulty in creating any variation of a lightsaber is the lack of a compact energy source today, so a portable knapsack and a wired handle connection are used for its operation, as in the case of a proto-sword. Hexmeath used the laminar flow effect to concentrate the burning propane into a long torch emerging from the handle. The gas is heated to a temperature of 2200 ℃ and quite confidently melts the metal, and with the help of calcium chloride and boric acid, the inventor gave the flame a unique personal touch. As befits a true Jedi.
