Engineers turn waste into electricity in Indiana project
News & Analysis  
1/29/2007   Post a comment
Environmental engineers in Indiana are engaged in a pilot program to build energy-recycling facilities that they claim will significantly lessen U.S. dependence on fossil fuels like gas and petroleum. The program aims to build a $12.5 million industrial waste conversion center, a $5.5 million hog waste conversion facility (including a 2.5-mile pipeline) and a shared methane-to-electricity conversion site. The buildings are due to be operational by 2008.

TI fellow on DLP: We did it with mirrors
News & Analysis  
1/29/2007   Post a comment
Solid-state physicist and Texas Instruments fellow Larry Hornbeck won an Emmy for his invention of the digital micromirror device, the microelectromechanical system at the heart of TI's digital light processing (DLP) technology for projection displays. In addition to advancing the state of the art for digital cinema, front projectors and HDTV, Hornbeck's MEMS micromirror is enabling 3-D metrology systems, confocal microscopes that eliminate the out-of-focus "haze" normally seen around fluoresc
