I don't understand the last two paragraphs (before "Power Points").... the article is mentioning "for the greater good" and some counter-arguments to points that haven't been made in the article itself! The benefits of their technology is clear, but they're defending it against arguments that have (presumably) been made without telling us what they are...
It's badly written. Another thing is people eat bacteria shit in the form of yogurt and cheese all the time. So it's not like they should have a problem putting it in their cars.
Those are some cool bugs though...
If you could break down sewage like that, you could link them up with an RV's toilet or people's drainage fields and let them pump their own shit into their gas tanks. Eventually.
