I assume this is basically a version of waterjet cutting (http://en.wikipedia.org/wiki/Water_jet_cutter), but it's pretty cool that it's portable and in production. (IMG:style_emoticons/default/smile.gif) It uses an explosive instead of a pump to get the water pressure.

[Dahrken]

Not really. Waterjet cutting use a continuous stream of high-pressure liquid, which can be loaded with abrasive for cutting hard materials, while this use an explosive charge to propel a single load of water through the target, like a water bullet and it's definitively single use only..

It's also cheap as hell, from the look of it.

[Yerameyahu]

Hehe. I meant that it uses high-pressure water to damage something, Dahrken. (IMG:style_emoticons/default/smile.gif)

[nezumi]

And an interesting way to kill a person. A bullet made out of water?

[Yerameyahu]

I like it as an alternative to primacord or shock-lock for B&E. Not as compact, though. :/

[Stahlseele]

if you're going to blow it up anyway, why not simply use the explosives without the water to do it?

[Yerameyahu]

Dunno. (IMG:style_emoticons/default/smile.gif) I assume it's safer. The news release is awfully short on 'why this?', right? AFAIK, that's because it's more like a corporate press release: "Provided by Sandia National Laboratories", but PopSci went ahead and bylined it as 'written' by their own person. Hah!

I just read a thread on plastic explosives the other day. You can hit C4 with a hammer and throw it in at fire and it will just burn (giving off poison gas), but if you set it on fire and then hit it with a hammer it will explode. C4 needs heat plus an impact to do its thing. Basically this blade thing delivers a huge amount of kinetic energy with out delivering much if any heat and little oxygen. In the video with the propane tank it exploded but it did not ignite.

It probably does not fail to set off the explosives all the time but it is better than the current practice of using explosives to safely detonate the explosives.

At least that is my interpretation.

It really is cool how simple the idea for the device is.

[Dahrken]

Explosive-launched water to destroy IED or suspected bombs is nothing new, but this specific package seems to have been designed and optimized for low cost, I think because there is a large potential market.

If I'm not mistaken, the impact of the water is strong enough to mechanically disrupt the IED and prevent it from detonating as planned by the builder, but much less likely than a contact explosion (for exemple from explosives tamped on the bomb) to trigger the charge, thus making the preocess safer and much less destructive to whatever is around the IED..

[Yerameyahu]

Seems like it'd be especially useful if your GM makes any significant used of bombs/IEDs in your games.

[CanRay]

Water Cutting Tools have been around for quite some time, and are very efficient and cost effective in areas with a lot of water, or have a lack of availability of steel bits. I think they started using them in Strip Mines, but I might be mistaken.

Their use as a "Disarming Solution" is interesting, however.

Izzit related to this thing?

Looks the same, only bigger. (IMG:style_emoticons/default/smile.gif)

Except for the wound, it leaves no trace. Pretty handy for clandestine killings.

[Nifft]

... or Fire Spirits.

[Dahrken]

... no traces except the blast and shrapnels from the container and detonation system. It's about as clandestine as the IED it is designed to destroy.

... or Fire Spirits.

The hard part about that is convincing the spirit to stay sitting on the thing, because it is rather short ranged. This makes it somewhat impractical outside of an ambush or other situations where you can lead the target into the right spot.

[Badmoodguy88]

Someone could make an impact hammer like in unreal tournament. Except when it makes contact it sets of explosives that propel water into the target at point blank range.

That would actually work as a bizarre melee weapon that would be useful against spirits... or tanks.

[Dahrken]

Such a weapon would be as dangerous for the user (or possibly even more !) for the user that for the intended target, because of that pesky action/reaction law. The same explosion that propel a load of water at a speed high enough to be useful against an heavily armored target will propel the rest of the weapon backward at a lower (but still excessive for the wielder's safety) speed.

[Yerameyahu]

Haha, I really don't think this is a good idea for a weapon of any kind. Like Dahrken said, it's not stealthy at all (noise, size, and there's a huge wound), and it's single-shot. It's a tool.

Make for an interesting sticky bomb if you could get it on, say, a tank turret.

Could make for cheap landmine tech.

[Yerameyahu]

I wonder how the price stacks up, actually. Landmines are *really* cheap already; you'd think precision-shaped 'water blade' devices wouldn't really be cheaper.

[CanRay]

IEDs are even cheaper in places that have seen war within a generation. Unexploded munitions and abandoned bases full of old bombs.

I saw one of those future weapons or similar shows, they had this flat piece of explosive, looked thinner than cardboard. Slide it under a door, it worked as flashbang. Tape it on the door with a bag of water behind it, it knocked the door in.
