We’re flushing free energy down the drain, but not for long

Clean energy can take many forms. We most often think of it as solar panels gobbling up radiation from the sun or massive wind turbines twisting in the sky, but if we rethink things a bit we can come up with a whole bunch of interesting ways to harness forms of energy that are wasted every day. The city of Denver is in the midst of one of the most extensive trials of unconventional green energy collection ever, with a new 250-acre facility for "art, education, and agriculture," according to NPR. What makes the massive indoor areas of the new National Western Center so unique isn't what will be inside, but what will be happening beneath the feet of visitors.

The sewer pipes that carry wastewater swiftly to a treatment center will play a huge role in the comfort of everyone that visits the center. A closed-loop heat exchange system will be used to keep the buildings cool in the summer and warm in the winter, and the wastewater that would be flowing out of the site anyway is what makes it possible.
