slave bacteria

 some bacteria "eat" glucose and "emit" hydrogen + CO2

Instead of reastaurants or other food institutions throwing all that food away, let's mix it all up in a vat containing a large population of bacteria that will break it down into its constituents, relaesing Hydrogen and CO2. The hydrogen can be fed directly into a fuel cell and the CO2 can be pumped into a nearby greenhouse (or paintball tanks).

Bacteria emit hydrogen gas http://www.politica...com/news/read/14875
Seems like someone is already baking this idea, sorry [jrjones1] [kuupuuluu, May 25 2006]

       Slave bacteria isn't uncommon in labs - bacteria is utilised to perform all sorts of useful tasks, but it's not been exposed to the open market as far as I'm aware. The 'waste' elements, as you say, can be used to power other facilities in the restaurant. [+]

       What kind of bacteria emits elemental hydrogen? Don't they produce CO2 and H2O? Why would they waste all that energy?

       Interesting. Maybe they are metabolizing so fast it's effectively anaerobic? So they forego oxidizing the hydrogen in favor of just breaking down glucose faster?

       Perhaps you could come up with an idea of your own, rather than just copying something in the news at the moment?

       Tsk, tsk, [Loris], you're supposed to welcome them to the halfbakery, point them towards the help file, and THEN jump all over them with hobnailed boots.
