As we all know, the lightsaber is an sophisticated weapon, for a a lot more civilized age. [Alex Burkan] is doing what he can to bring that technology to fruition, and even secured a Guinness world record in the process.

The build counts on an electrolyzer, splitting water into hydrogen and oxygen gas which is stored in a small tank. This gas can then be released and combusted in a burning stream, creating a weapon with a vague resemblance to a movie-spec lightsaber. With the hydrogen torch burning at temperatures of thousands of degrees, it’s hot enough to melt steel just like in the films.

While the concept of operation is simple, actually building such a device in a handheld size is exceptionally difficult. [Alex] highlights crucial features such as the flashback arrestor that stops the gas tank exploding, and the output nozzle that was very carefully created to produce a surprisingly long and stable flame.

The resulting device only burns for 30 seconds, so you’ve only got a short period of time to do what you need to do. However, unlike previous designs we’ve seen, it doesn’t use any external gas bottles and is entirely self-contained, marking an crucial step forward in this technology. video after the break.
