High pressure water to kill weeds?



What do you think about possibility to use high water pressure pump / beam to kill the weeds?

I see the 12v pumps are generally available…



I like that idea!
(I also like laser beams, high-power projectiles and guided missiles)
The thoughts I have about high pressure water (HPW) are:
1). Added weight to the Y & Z structures
2). Added force from the water jet. (Every action has an equal & opposite reaction)
3). Line pressure & hose rupture.
4). If it works, I think one could get very accurate targeting.
