That is crazy when you think about it! About a year ago there was a lot in the media about the importance of conserving water, which didn't have much of an impact in Scotland, where we're practically drowning in it! Though this summer has been unusually dry, so I'm sure it won't be long before someone tries to make money out of it.
Hmm... we were discussing the theories about water-powered vehicles recently. Maybe the technology for that is indeed out there, but it won't be released on a gullible public until water is seen as a very scarce and expensive resource...
