I've never really understood why diesel and tarmac NEED to be able to get along. Why not work on preventing diesel spills in the first place?
To be fair, if minds like these never came up with new stuff, we'd never get anywhere, and likely would still just be getting around to cutting the corners off square wheels. But the sheer expense of such a system is going to prevent their employment for many years, maybe decades to come. Solve THAT and you may have a goer.
Shit, this positive thinking lark is hard work ain't it? Foc it, it'll never happen
