Kent in England is about to become an enormous lorry park.
Today’s invention is to help it avoid becoming the world’s biggest outside toilet.
It consists of a fleet of motorcycles each of which carry a portable toilet, together with a pull-up shower screen.
Lorry drivers could call for one of these to turn up beside their truck and pay to use the facility.
Once the bike’s tank was full, as it were, it would be taken to a disposal facility and emptied (possibly somewhere near Westminster).
