THE VANISHING INVENTION
In 1998, a Valencian professor made an amazing claim. Professor Antonio Cervilla discovered
how to use water as a substitute for petrol. The scientist said that you could drive from Bilbao to
Valencia on just half a litre of water. His invention uses a molybdenum compound to break down
water into hydrogen and oxygen. Unlike other methods, no electricity is required and the
reaction happens at atmospheric temperature. This impressive technology is based on the way
plant enzymes break down water. The use of molybdenum is the perfect choice because,
although rare, it is cheap and found all around the planet.
 Since the claims were made, nothing more has been heard about this fabulous technology.
There is no explanation for the disappearance anywhere on the internet, apart from a list of
similar inventions which have also vanished. An inventor from the Philipines called Daniel Dingel
developed a water-fuelled car but was arrested and sentenced to 20 years in prison. If this
technology were to become widely available, it would prove disastrous for petrol station owners
and would also save the planet from the impending environmental catastrophes being caused by
pollution.

A. addition

A. enzyme

D. invented
