| New insights into the one-in-a-million lightning called 'ball lightning' Posted: 07 Aug 2013 10:00 AM PDT One of the rare scientific reports on the rarest form of lightning -- ball lightning -- describes better ways of producing this mysterious phenomenon under the modern laboratory conditions needed to explain it. The phenomenon puzzled and perplexed the likes of Aristotle 2,300 years ago and Nikola Tesla a century ago.  |
| Self-healing solar cells 'channel' natural processes Posted: 07 Aug 2013 08:56 AM PDT To understand how solar cells heal themselves, look no further than the nearest tree leaf or the back of your hand. Researchers have developed a regenerative solar cell that uses branching channels to best mimic natural processes.  |
| SkySweeper robot makes inspecting power lines easy and inexpensive Posted: 06 Aug 2013 11:55 AM PDT Mechanical engineers have invented a robot designed to scoot along utility lines, searching for damage and other problems that require repairs. Made of off-the-shelf electronics and plastic parts printed on an inexpensive 3D printer, the SkySweeper prototype could be scaled up for less than $1,000, making it significantly more economical than the two models of robots currently used to inspect power lines.  |
