How can I generate power for my home using hydrogen producing bacteria?

Question

This seems hopeful: http://www.energycooperation.org/bioproductionH2.htm

I'm looking for an entire method, a protocol to extract the bacteria, use them efficiently, store the hydrogen, and also burn it efficiently to produce my own power in a small apartment with not much space. Thanks for your ideas on this.

I don't want to power my entire home. Just a light bulb, or perhaps a laptop.

Answer 1

if anyone knew how to do this more economically than other energy sources, then they would be doing it, and nobody is

so, no one can provide an "entire method"

here are a couple of things you can start working on that you will need to solve, invent, develop for the process

*how will you feed your bacteria? if you are going to make enough hydrogen to make it worth it, you will need lots of bacteria and lots of food for them (the caloric energy of the food you give them will have to be several times the amount of energy you will get from burning the hydrogen)

*how will you compress the hydrogen for storage and use? the little creatures must live near atmospheric pressure so your hydrogen will evolve at that pressure. to store it or use it you will need to compress it, this is an energy intensive process

This is really just a fermentation process like is used to make ethanol (for drinking or burning). Every indication so far is that the fermentation to ethanol is much more efficient. That is why fermentation plants to produce ethanol for fuel exist and in a few cases are economical, and commercial fermentation to produce hydrogen for fuel does not exist.
