28,8Kj ElectroThermal Gun! (Soon handheld)

What size capacitor bank did you use on the smaller size one?

[Gunner]

Larda, could you demonstrate with your bigger or smaller gun with 10kJ charge? And you could shoot to wood plank?

[POLAND_SPUD]

wow..... amazing
I hope you are going to build your next gun with 2" barrel

when I asked how much gases are produced I basically ment that you could measure it somehow to find out whether lenghtening to barrel would increase muzzle velocity and how much longer barrel you can use

[jon_89]

Has anyone tried this?http://www.instructables.com/id/How-to- ... ectrother/. Do you think it would have ok power or horrible power. I am thinking of maybe adding an extra capacitor or two.

[Gunner]

I could try that, looks very cool!

[Gunner]

Could this schematic works?

[Hotwired]

Yep thats the basic idea but the two terminals have to be insulated from the walls if they're made of metal.

[Gunner]

But how close two terminals have to be if voltage is 800V?

[DYI]

Very close, if you're jumping an air gap. This works by passing current through a conductor, so the voltage doesn't have to be absurdly high.

[Hotwired]

Well 3,000,000V can jump 1m so 800V can jump 0.2666... mm

[Gunner]

So is this gun based on it that the air between electrodes becomes to plasma and the so the pressure increases? And Larda uses aluminium powder that turn into plasma?Thanks!

[Gunner]

As jon_89 asked, what is your capasitor bank in smaller one?

[Gunner]

Larda has forgot us...

[Larda]

Sorry, forgot to mark "Notify me when a reply is posted" when i posted, so i missed all the new replays.
Not sure which capacitor-bank i used for the smaller one, i think bank was about 2.5-4Kj.

I have some thoughts of of building a "handheld" version of the ETG, but i am not sure if i am reckless enough to try using it .

[sniper hero]

wow that is incredible !
the sound is so cool and the vids are awesome!
I love this gun so much
