Pee power. Scientists may have found a way to extract hydrogen from urea, one of the main major components in ordinary pee. That compounds is way for the body to get rid of toxic ammonia that comes out at the end of various metabolic processes.
In many rural areas, urea would be the ideal source of nitrogen for fertilizing plants but it may also be a source of power one day.
Hank Greek at EcoGeek says:
Gerardine Botte at Ohio University has figured out an easy and efficient way to break the bonds in urea to produce hydrogen. The process consumes roughly one quarter of the energy needed to electrolyze water. And, yes, the world has a fairly plentiful (and renewable) supply of urea. Maybe not enough to power all our cars, but it’s a start.
And all this time, I was only interested in the nitrogen. 🙂
Best Buy! This next story is about the role of national retailers in transforming the economy to greenness. Joel Makower gives us Best Buy as an example. He sums it up really nice as to the role of these big companies:
While cutting-edge innovation will likely come from countless start-ups, it will be up to the mass merchandisers to accelerate market uptake beyond the green devotees and early adopters.
Canadians can! The country up north is one of my favorite countries. I’ve also wondering what the government was doing to encourage corporate sustainability. Our friend Tyler Hamilton at Cleanbreak has a summary.
In other news, Robert Rapier reminds us that thermodynamics wins.
Celcias reports that the 100th coal plant has been defeated. I’m sure Lester Brown would be proud!
Finally, is the big battle between Google and Microsoft? Earth2Tech suggests otherwise.
