I have a question i have to write a short note on water powered cars??
Answers
Answer:
To fuel a hydrogen car from water, electricity is used to generate hydrogen by electrolysis. The resulting hydrogen is an energy carrier that can power a car by reacting with oxygen from the air to create water, either through burning in a combustion engine or catalyzed to produce electricity in a fuel cell.
The name ‘water-powered’ cars is misleading. The power to move the vehicle actually comes from the burning of hydrogen, which is derived through electrically splitting water molecules into hydrogen and oxygen gases through electrolysis. In burning the hydrogen gas water vapor is produced, meaning that the combustion is clean, which is why it is of interest to the automotive industry who are striving to adopt cleaner technologies.
The water-powered car has long been shrouded in skepticism and controversy ever since it was invented. Many scientists believe that the energy it takes to split hydrogen from water outweighs the energy output you get from the hydrogen combustion to power the car. Therefore the energy you expend to split the water may as well be used to power the car, in other words, you may as well look to electric vehicles.
Water Fuel Cell
Stanley Meyer claimed to have invented a water fuel cell that used less energy to power the electrolysis to split hydrogen from water than conventional science would dictate. However, in 1996 an Ohio court found these designs to be fraudulent. There was nothing revolutionary about his invention, the cell was using conventional electrolysis, and while his invention is now in the public domain, no vehicle manufacturer has yet tried to copy his work.
