I was listening to NPR Science Friday and overheard an amazing discovery. Scientists at Penn State were able to use bacteria to convert biomass (sewage, old food, anything organic) into hydrogen, at 90% efficiency. If this process can be scaled up, you could use 5% of our national electricity consumption to create enough hydrogen to fuel our entire transportation sector. Every car, truck train and plane! All with a little bacteria and leftovers! Someone in industry please invest in this technology!
