Sunflower-Inspired Pattern Increases Concentrated Solar Efficiency

There are only a handful of concentrated solar power (CSP) plants in the world. The technology could potentially generate enough renewable energy to power the entire U.S., provided that land and sunlight are in ample supply. Researchers have now come up with a design that reduces the amount of land required to build a CSP plant, while increasing the amount of sunlight its mirrors collect.

Pollution Reducer & Heat Generator

New technology from North Carolina State University and West Virginia University can reduce air pollutant emissions from some chicken and swine barns while also reducing their energy use by recovering and possibly generating heat. A proof-of-concept unit incorporates a biofilter and a heat exchanger to reduce ammonia emissions.

Self-Healing Electronics Could Reduce Waste

When one circuit within an integrated chip cracks or fails, the whole chip – or even the whole device – is a loss. University of Illinois engineers have now developed a self-healing system that restores electrical conductivity to a cracked circuit in less time than it takes to blink.
