and for my english friends:
From the Teutonic technology will soon arrive on the markets a new type of fuel use, hear! hear! none other than ... piss.
It will serve, they say, to reduce air pollutant emissions. But, I might add, not only in the atmosphere. It will decrease also ... on Earth.
From now on, no more forced stop in an emergency little squares, motorway services in behind the bushes or under the viaducts to hide from prying eyes of other car drivers.
In a little will be enaugh to adopt a container to keep in the car, possibly with a funnel for easy pouring, and you're done.
"Dad! I pee!"
"Have you not seen the bin behind the seat? Make it there, because then we fill up!"
