I also had another thought. In countries like Africa where Sunlight is available in abundance efforts have been made to make solar based distillation process to convert dirty pond water into drinking water. That sounds to me to be a much cheaper option and such systems are affordable too. This technology is available today!

Such a technology will be a real boon for countries like India where so much water goes down the drain during the season of Abundance ( monsoon season) and then in summer people have to walk miles to fetch a bucket of water to drink. This technology will enable people to harvest their own sewage to convert it back to potable water

Agree with Colin,The distance covered is great and in this case who will not like the idea of being able to use the wasted water and use the converted bi product specially when it is a commodity as useful as electricity.Feels like a dream coming true but tell you we are still miles away from the Reality of making use of the same in commercially viable options.

I agree with Colin. Something to watch. In general, the integration of biotechnlogy, materials technology and electronics is bound to wield many exciting new applications. And the field is still wide open. The future of our kids may depend on it.

Generating enough electricity from sewage to run a water treatment plant sounds like a serpent eating its own tail, but these OSU researchers may be onto something. There are many other efforts underway to create bacteria-powered fuel cells, but more conventional approaches have always won out in specific applications areas--usually because keeping bacteria strains alive is a job for pros not consumers who just want the energy generated. However, sewage treatment plants have a vested interest in keeping those bacteria happily generating electricity. And if such plants can generate enough electricity to become self-sustaining, then it might be possible to solve at least some of the world's clean water woes too! This is definitely a technology to watch (and keep our fingers crossed that is becomes commercially viable).

As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
