One day France may be not the only place where you see people driving around with chickens in the back of their vehicles.

Scientists in Delaware, USA, have discovered a remarkable, unexpected and inexpensive way to store hydrogen fuel– using carbonized chicken feather fibres.

The question of storing hydrogen as fuel has traditionally been a enigmatic and expensive dilema. For example, a car with a 75 litre hydrogen storage tank made from carbon nanotubes or metal hydrides– currently two of the best ideas – would add $5.5 million or $30k respectively to the cost of that vehicle.

A storage tank made from carbonized chicken feathers, however, would only increase the cost by a mere $200. The green bio-material would also help to resolve the problem on how to dispose the 2.7 billion kilograms of chicken feathers generated each year by commercial poultry production.
