As most of the troops leave the area, I am sure that this DIY solution will still be made by the locals. It'll be like radiation detectors in Japan's Fukushima area. It is a sad state of affairs. Perhaps the mindset that is creating the IEDs will start to evolve past violence sometime soon.
Cabe, this is a great development. Many of our casualties in Iraq and Afghanistan, if not a majority, are from IEDs. Being able to detect the chemical signature from a distance will help minimize this. It is all we can do to use our technological edge to remain one step ahead of the terrorists.
Researchers have been working on a number of alternative chemistries to lithium-ion for next-gen batteries, silicon-air among them. However, while the technology has been viewed as promising and cost-effective, to date researchers haven’t managed to develop a battery of this chemistry with a viable running time -- until now.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies.
You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived.
So if you can't attend live, attend at your convenience.
