I couldn't resist this. A blog post on the GenGreen Life web site this week reveals two innovations in hydrogen-powered car research.
One of the problems, it seems, with hydrogen fuel cell cars is that the fuel tank needs to be extremely strong in order to store enough compressed hydrogen for a decent driving range. A tank made of carbon nanotubes would do the trick but would add about $30 thousand to the price of the car. But researchers at the University of Delaware accidentally discovered that inexpensive hydrogen tanks of great strength could be made using keratin fibers found in chicken feathers, a plentiful and renewable resource.
The other discovery noted in the article was that hydrogen can be derived very efficiently from urine. I know, I know. But think of it - you're on the road and running low on fuel and you need to find a bathroom and there's no gas station for miles. Voila! Talk about killing two birds with one stone.
