By Brett Israel, UC Berkeley News. For GSS Energy Use chapter 10. Excerpt: Yearly 70 percent of the energy produced in the United States each year is wasted as heat. Much of that heat is less than 100 degrees Celsius and emanates from things like computers, cars or large industrial processes. Engineers at the University of California, Berkeley, have developed a thin-film system that can be applied to sources of waste heat like these to produce energy at levels unprecedented for this kind of technology. The thin-film system uses a process called pyroelectric energy conversion, which the engineers’ new study demonstrates is well suited for tapping into waste-heat energy supplies below 100 degrees Celsius, called low-quality waste heat. ...The new results suggest that this nanoscopic thin-film technology might be particularly attractive for installing on and harvesting waste heat from high-speed electronics but could have a large scope of applications. ...The research will be published April 16 in the journal Nature Materials. The research was supported, in part, by grants from the Army Research Office and the National Science Foundation....  http://news.berkeley.edu/2018/04/16/thin-film-converts-heat-from-electronics-into-energy/
