Microbial Fuel Cell Turns Waste Into Hydrogen
Every time I see these stories about bacteria turning garbage/waste/dirt/steel/sunlight/etc into something we can use, I'm always worried about it just being snake oil. Of course, had you asked me this about 50 billion years ago, I probably would have been skeptical of photosynthesis. Assuming this does work, I cannot imagine how difficult it would be to actually capture the hydrogen output and store it... let alone ship it on so it could be used broadly. Um... plus THIS whole thing.
