Vinegar + water + bacteria + electrons = hydrogen?

Currently the most cost effective means of producing hydrogen is through steam reformation of natural gas. While this process is efficient, it does produce CO2. Electrolysis of water produces only oxygen and hydrogen but takes more electricity than the energy you can get from the hydrogen produced and is at best 50-70 percent efficient.
