The world's first lightsaber with plasma as the blade of light is developed

When I created a lightsaber that heats metal at high temperature and published it on YouTube, I was criticized that 'this is just a heated stick, not a lightsaber', so I actually made a fictitious item that appears in science fiction movies The

Hacksmith, a YouTube channel that creates it, has developed the world's first lightsaber that actually produces a plasma blade. The whole story of development that can only be said to be 'awesome' that brings together technology and funds is available on YouTube.

4000 ° PLASMA LIGHTSABER BUILD (RETRACTABLE BLADE!) --YouTube


James Hobson, the host of the Hacksmith on the YouTube channel, has recreated a number of fictional fiction items in the real world, such as Iron Man's Repulsor and Thor's Hammer .

Lightsaber has also tried many times over the past four years.

Occasionally there was a fuss about fire trucks being dispatched.

Version 1 is a nickel-titanium alloy wire heated at a high temperature ...

Version 2 uses tungsten titanium alloy.

However, when I actually tried to fight ...

It turned out to be extremely dangerous.

After that, he also developed a titanium Cairo Ren type lightsaber that was output by a 3D printer. These lightsaber developed in the past were very similar to the lightsaber that appeared in the movie in terms of appearance and sound, but ...

The internet was flooded with comments such as 'It's just a hot stick' and 'It's not such a lightsaber.'

So Hobson decided to make a new lightsaber that was closer to the original. The lightsaber that appears in the movie is a 'blade of light created by plasma' that melts objects. In order to realize this scientifically, the hypothesis that 'lightsaber plasma is controlled by a magnetic field' can be considered, but it seems difficult with modern technology.

So Hobson decided to make a lightsaber with a plasma blade using the phenomenon of

laminar flow . Laminar flow is a flow created by the movement of each fluid element.

First of all, from the design of the design. The design of this lightsaber is

steampunk style.

I will actually scrape the brass to make a pattern.

Shaving while pouring water ...

I will carve out multiple parts.

Welding work.

I will combine each part.

This is the completed one.

When the handle is completed, the next step is the core part, 'How to create a blade of light?' Since the blade of light requires a considerable amount of energy, a power pack is required separately from the main body. The power pack uses

liquefied petroleum gas for home use, such as for barbecues.

It is said that plasma will be generated if the flow of liquefied petroleum gas is concentrated at one point using a special nozzle and laminar flow.

This is the nozzle, and the price is quite high at 4000 dollars (about 420,000 yen). This nozzle is used to control the amount of oxygen inhaled and raise the temperature of the flame to create plasma.

So, to the experiment. Wear goggles for your safety ...

When ignited, a fluffy flame blows out from the nozzle ...

It becomes a lightsaber in no time. It is a blade of blue light.

It is also possible to actually cut things.

You can also use the flame

reaction to change the color of the flame. With boric acid ...

To green.

I will change the color steadily.

Calcium chloride to make it amber.

Red

with strontium chloride .

It turns yellow with

sodium chloride .

When you line up the five colors, it looks like this.

We also designed a power pack to control these ...

Finally it looks like this.

When you output with the touch of a button, a blade of light appears like a real lightsaber.

In addition, the state of testing with the newly developed lightsaber was released as member-only content at the time of article creation, and is scheduled to be released to the public on October 14, 2020.
