let's talk about fuel baby, let's talk about nano and me...

mmm Do you smell something? Oh wait, it's just the fuel. I know this isn't directly related to bioarchitecture but one might need a biocar to park in a biogarage, and well you get my drift.

So, in an article I was reading on Ecogeek, they were saying how researchers at University of Dayton have been able to use an array of carbon nanotubes to perform the same catalytic activity that Platinum produces in a standard fuel cell. Platinum is good at splitting up the oxygen (O2) molecule into two oxygen ions (O+) at the cell’s cathode. Platinum is a pricey metal if you were not aware and for a typical passenger car, the platinum catalyst can cost about $4,000. That's quite pricey.

The carbon nanotubes are doped with nitrogen. The full name of these wonders are nitrogen-containing carbon nanotubes, or VA-NCNTs. The Nitrogen prevents the carbon from reacting with oxygen to form CO, a process called “poisoning”. The CO builds up on the surface, and reduces the effectiveness of the catalyst over time. But these VA-NCNTs keep carbon unreactive, and thereby prolong the catalyst’s lifetime.
Go carbon!

I want to know though what will the wastes then be? And how can we reuse them?
