Invention number 2: the genetically engineered, lawn mowing slug

Posted by Andrew Cooper on September 14, 2008

A while ago on this blog I invented the nuclear powered tea pot as a way of illustrating the difference between an invention and an innovation.

I’ve just been outside looking at our lawns (that makes them sound rather grand, they aren’t but there are two of them) and the slugs who, as it’s now dark, are happily grazing on them.  

It’s been a great summer for slugs, thanks to the fairly constant rain, and dozens of them have grazed our lawns every evening.  Unfortunately, they don’t graze sufficiently well to prevent me having to mow the lawns, which I did this afternoon.

I have, therefore, invented the lawn mowing slug.  This is a species of slug which has been genetically engineered to sleep harmlessly in flower beds (i.e. without eating all the flowers) during the day and then move onto the lawn in herds (or whatever the collective noun for slugs is) and graze systematically from one end to the other, thus obviating the need for mowing.  

Obvious, isn’t it?  Why has no one thought of this before?  Please feel free to patent and develop the idea, particularly if you are a genetic engineer.  Do drop me a line when you’ve cracked it.
