I actually think about mines quite a lot. They're a scourge. And it's depressing that the most common demining tools are a length of poking wire and patience. Too often held by children.
My thinking was always along the detection and defusing line, but another Australian has come up with an idea which is elegant in it's application of brute force: he basically built an armoured earth tiller that explodes them in situ. (Although, looking for the link, this isn't a new idea either)
Interesting note on Wikipedia about neutron imaging. Finally a practical application for the Farnsworth Fuser?
Indeed! I was reading about that, but alas it looks like the project is being derailed somewhat by the requirement to stop the plant from reproducing in the wild, (using a growth co-factor) so as to prevent genetic crossover into the environment. Bah. As if this wasn't one plant that you WANT growing everywhere like a weed. (And as if nature isn't going to take that gene out in it's first field patch.)
This is exactly the kind of application of genetics us Mad Scientists have been telling people about for years. But now it's here, Monsanto has already poisoned the well. Grrrr.
