Putrid Power

The search for energy sources leads to some interesting places.  Earlier this week it led to the deep fryers of the Calgary Stampede.  Today, it delves into the sewers of British Columbia.

Regardless of your opinion on Stampede cuisine, this power source is undeniably less pleasing to the senses:  Sewage.  In places such as Vancouver, sewage is being harvested for hydroelectric and heat energy.  The two sources even work together as the hydroelectricity powers the heat extraction.

What is especially attractive about this normally repellant substance is that the supply is pretty much unlimited.  So far the results have been quite positive with B.C. paving the way in North America.

It will be interesting to see what the future holds for this power source.  Sewage is something that any large city has an enormous supply of, and if there continues to be promising results, it would be hard to see any reason not to use this resource.
