I think those interested in energy independence and alternative energy sources should look into the new Oslo plant written about here in Reuters. If we build one of these plants near the nation's capital, we could probably power the entire world. What's the energy source you ask (as if you haven't figured it out yet)? Human sewage. Does that sound horrific? So does the millions of gallons of oil we spill into our environment sound better (and that includes all the oils and oil based products we dump down the drain, toilet, and into our gutters -- this means you)? The article even examines the inconsistent supply of the new plant's "fuel source." It gave me a chuckle.
Okay, I'll get off of my soapbox. Check out the article for an interesting way that people deal with energy and waste.
