From Alex Green
The amount of salt on Yorkshire’s motorways over the winter, combined with bright winter sunshine, made car windscreens opaque within minutes. So yes, from drivers’ point of view as well as the environment’s it is time to use a safer alternative to de-ice roads – such as that in the patent described in “A greener antifreeze” (20 December 2003, p 29).
