A Ghost Busters-style backpack water cannon for firefighters

A <i>Ghost Busters</i>-style backpack water cannon for firefighters

This is designer Jan Thinius's conceptual "Impulse Gun," and it's basically the Proton Pack from Ghost Busters, but made to fight fires instead of Slimer. Instead of having to rely on running a hose back to a hydrant, every fire fighter has the water on their back.
So, you may be thinking, "Why not just use a fire extinguisher? Isn't that about the same thing?" I thought that, too, but fighting fires with high-pressure water shot out of a nozzle is different as it penetrates deeper into a serious blaze.
Man, it'd be great if some of these futuristic firefighting techs actually came about. At least this firefighting motorcycle is real, and can help tide us over.
