2000-09-18 – Landmines are still a problem.

Landmines are still a problem. So is worn tyre disposal. Combining the two may bring many benefits. Using several easily found parts, it would be a simple matter to rapidly reduce the number of mines found in an area. By reaching a slightly higher area, a row of tyres perhaps 15 wide, of the same diameter, could be tethered together with a rope. The “roll” of tyres is then assembled to point downhill over the mined area. From cover, the chocks are pulled, and a loosely assembled cascade of tyres is released. The amount of bouncing is reduced by the combined weight of the heavy rubber, and the loose restraining action of the rope. The rope is simply knotted at the appropriate place to hold two wooden discs. This prevents them scattering or diverging paths. As a further precaution, the rope is also looped for slack. In the event the tighter line breaks, the slack line will not, allowing the dragging of all the tyres back to the top, to be reset, and run again.

In this way, a large path through a sloped area could be cleared by
unskilled labour. The rope allows the tyre roll to travel quite slowly down the
slope, so avoiding missing any mines by jumping over them. The loose and
resilient nature of the tyres should mean they are never totally broken on a
side, and, of course, there are many spare bald tyres to repair the roll.
