"Actually it only requires a small percentage of the city’s daily output. And producing enough electricity for 8,000 home isn’t too bad for a pilot plant using waste."

Proof, please. How MUCH of the city's daily output??? And 24 MW is, in my book, an insignificant amount of power.

"Sounds way better than algae oil."

Not really. Methane from poop isn't a transportation fuel, which is what is needed most.

Here are two web sites that covered the Renton, Washington project, www.msnbc.msn.com/id/5335635 - 58k - Cached - Similar pages

One link I posted to one site doen’t work so if You google , “Distributed Energy Renton Washington” and then find among the first few sites, “Distributed Energy/ Fuel Cell Uses Bio-gas From Sewage to Generate.....” it has some more details. If you have any trouble locating them let me know.
But the math is: the city discharges 86 million gallons of waste/day and the gas generation uses about 1 million gallons/day. That’s less than 2%.
CNG(mostly methane) can be used as a motor fuel and is. So far what algae oil has generated is extravagant claims and press releases. I’ve already posted many of them so I’ll not repeat them here.
