Yes. It's a methane extraction process. To me, that says that the primary process is still required.
I think it`s part of sewage processing, or can be made so. For example, the Hyperion treatment plant near Los Angeles uses it to produce most of the electricity needed to run the plant - the methane process itself generates more power than it uses. It also makes the next stage of processing easier.
The results from that plant are impressive. It handles a huge amount of waste, uses less energy to do so, produces fertiliser and performs the necessary function of processing sewage, so I think the methane generating process is useful.
I think using it for cars is more about publicity than substance, though.

"In fact, does this process use more power than normal sewage processing?" Yes. It's a methane extraction process. To me, that says that the primary process is still required.
"If it does, are the results better?" I say "no" because in an environment like Detroit, the yield equates to work commute for one adult. The article immediately touts the car as an electric alternative. I took that as, by extension, they are thinking their Petroleum-methane hybrid is a viable alternative to my currently-in-use petroleum-electric hybrid. I would like to know the origin and at what volume of electricity went into pumping, mixing, collecting then compressing the methane. Then, since the car still uses petroleum, what was the resulting petroleum fuel efficiency? My particular Fusion has been well into the 50`s of MPG. This year, between 04-10 and 05-10, I went 700+ miles on 14 USgal.
