Submission + - An Electric Boost for Bicyclists (nytimes.com)

gollum123 writes: Detroit may be introducing electric car designs and China may be pushing forward with a big expansion of its highways and trains, but people and delivery workers in New York, postal employees in Germany and commuters from Canada to Japan — are among the millions taking part in a more accidental transportation upheaval- the electric bikeIn turn, the booming Chinese electric-bike industry is spurring worldwide interest and impressive sales in India, Europe and the United States. China is exporting many bikes, and Western manufacturers are also copying the Chinese trend to produce models of their own. From virtually nothing a decade ago, electric bikes have become an $11 billion global industry.In the Netherlands, a third of the money spent on bicycles last year went to electric-powered models. Industry experts predict similar growth elsewhere in Europe, especially in Germany, France and Italy, as rising interest in cycling coincides with an aging population. India had virtually no sales until two years ago, but its nascent market is fast expanding and could eclipse Europe’s in the next year.. It began in China, where an estimated 120 million electric bicycles now hum along the roads, up from a few thousand in the 1990s. They are replacing traditional bikes and motorcycles at a rapid clip and, in many cases, allowing people to put off the switch to cars.

Submission + - Wireless network modded to see through walls (technologyreview.com) 1

KentuckyFC writes: "The way radio signals vary in a wireless network can reveal the movement of people behind closed doors, say researchers who have developed a technique called variance-based radio tomographic imaging which processes wireless signals to peer through walls. They've tested the idea with a 34-node wireless network using the IEEE 802.15.4 wireless protocol (the personal area network protocol employed by home automation services such as ZigBee). The researchers say that such a network could be easily distributed by the police or military wanting to determine what's going on inside a building. But such a network, which uses cheap off-the-shelf components, might also be easily deployed by your neighbor or anybody else wanting to monitor movements in your home."

"Ultimately, the energy capacity of lithium iron phosphate is lower than that of other lithium-ion battery materials, making Ceder's advance of limited value, says Jeff Dahn, a professor of physics at Dalhousie University, in Halifax, Nova Scotia. This battery is good for acceleration, but not as much for long range."

Emphasis mine. As has been pointed out above, the practical use for rapid-discharge is in conjunction with other types of high-density storage. I envision it as analogous to the RAM and HDD paradigm.

Submission + - The darkside of Google taking over your ISP's emai

SlinkySausage writes: "Google is offering ISPs the opportunity to turn over their entire email system to Google, with all customer email hosted as Gmail accounts. This would allow Google to rapidly grow its userbase (it trails a distant third to Yahoo Mail with only 51million users compared to Yahoo's 250million and Hotmail's 228 million users.) There are some obvious benefits to end users — Google is offering ISPs mailboxes of up to 10GB per user. But APCMag.com has posted an interesting piece looking at the "dark side" of the deal, not least the fact that it simply reinforces the attachment people have to their ISP's email address, making it much harder to change ISPs if a better deal comes up. Question is: is a 10GB ISP mailbox for every ISP user a sufficient benefit to outweigh the numerous downsides?"
