Simple Solar Water System Devised to Kill Pathogens

(Greg Riegler/Flickr)

Engineering and food science faculty at Purdue University in West Lafayette, Indiana designed a solar device to kill waterborne bacteria that the inventors say can help provide clean drinking water to millions of people in developing countries. Civil and environmental engineering professor Ernest “Chip” Blatchley and food science biologist Bruce Applegate, with . . . → Read More: Simple Solar Water System Devised to Kill Pathogens

Protocols Linking Underwater Devices to Internet Proposed

Tommaso Melodia (University at Buffalo)

Engineers from University at Buffalo in New York are proposing a common set of wireless protocols for connecting underwater sensors, like those detecting tsunamis, to the land-based Internet. Electrical engineering professor Tommaso Melodia and graduate student Yifan Sun will present their proposal next month at ACM’s International Conference on . . . → Read More: Protocols Linking Underwater Devices to Internet Proposed
