Banishing energy-hogging treatment plants and rotting pipes

Every year, Americans produce 12 trillion gallons of wet sewage and burn 21 billion kilowatt-hours of electricity to clean it to drinking-water standards. Why not put the smelly stuff to good use? Thanks to clever new technology, sewage will be reclaimed to provide power, produce fertilizer and, eventually, yield clean water. In other words, sooner than you think, you'll be drinking your own urine.

Oceanlinx, an Australian company that makes devices capable of converting the juice from ocean swells into electricity, has signed a deal with the state of Rhode Island to produce two separate offshore facilities that could end up powering more than 15,000 homes. One of the facilities will boast a bunch of the devices, each of which will be about 60 feet wide and 30 feet tall. Read more about how they work here. They're big, but they'd sit far enough offshore so they wouldn't be an eyesore.
We wrote about the technology at the beginning of last year—at that point the company was called Energetech—and back then everyone was a bit more optimistic in terms of the timetable. Now it will be at least two years before the devices start generating electricity. But at least things are moving along again.—Gregory Mone
