Biofuels of the future
Finding a truly renewable energy source is a task scientists the world over are faced with. Transforming plants into "biofuels" was once a great hope, but the process requires energy and so may actually contribute to global warming. This week we explore whether a new generation of biofuels could succeed where the previous one failed.
We head to the beaches of Brittany to speak to a team of scientists working on creating biofuels out of seaweed. Could the slippery stuff be the answer to the energy crisis?
Surprising but true, researchers in Scotland are transforming Scotch whisky by-products into a green source of fuel. We check it out.
And in the south west of France, farmers are managing to turn leftover fat from cooking duck into a fuel to power their farm equipment.
