Demining ideas

So something that I want to do someday is to create demining machines. If any of you out there want to try my ideas, feel free.

1) A tower crane with a 1000 gallon forest fire helicopter-borne water dump bucket (like they use with the Chinooks). Yep, that simple. Fill 'er up, swing it out, and dump. Rinse and repeat. It should set off most antipersonnel mines. If you repeat the process several times per patch you should be able to make it relatively easy to do a manual survey for 100% clearance.

2) A waterjet on tracks. Basically, you have a modified Bobcat on tracks that pulls a water tender. You run a high pressure water pump off a PTO or hydraulic motor-water pump accessory to power a series of nozzles on a flexible fiberglass or Kevlar composite pole. You'd likely need to pulse the jets so that the jerk (dF/dt) sets off the mines; you can do this with high flow valves and an accumulator upstream. The nozzles would be angled about 45 deg. to the vertical and held maybe 10 inches off the ground. The nozzles themselves would be protected from frag by copper collars. The driver/operator cab of course would be armored and have portal windows, likely made from AlON (aluminum oxynitride).
