Hugh Pickens writes "Watch a video of comedian John Hodgman speak after Barack Obama at the recent Radio and Television Correspondents Association dinner in DC and discuss the central question of our age: "how we can heal the great and shameful division that has plagued our nation for so long — the age old conflict between jocks and nerds" and ask Obama: Are you now, or have you ever been, a nerd?"

Rollable E Ink Displays Get Real 116

An anonymous reader writes "Two years ago Philips unveiled a prototype of a functional electronic-document reader, called the Readius, which could unroll its display to a scale larger than the device itself. Unfortunately, that was only a prototype. According to Cnet, however, Polymer Vision, which spun out from Philips in 2006, has redesigned the Readius and turned it into a real product that it is going to be available by the end of this year. There are some notable differences between this Readius and the prototype version, in particular, the ability to display 16 shades of grey instead of just 4 and the connectivity options. What doesn't make sense though, is given the energy efficiency and easy-to-read high contrast functionality of E Ink, why other than Motorola with its Motofone, has no other cell phone manufacturer incorporated E Ink technology into its handsets?"

Creating Power From Wasted Heat 186

Roland Piquepaille writes "Today, about 90 percent of the world's electricity is created through an indirect and inefficient conversion of heat. It is estimated that two thirds of the heat used by thermoelectric converters are wasted and released. But now, researchers from the University of California at Berkeley have found a new way to convert this wasted heat into electricity by trapping organic molecules between metal nanoparticles. So far, this method of creating electricity creation is in its very early stage, but if it can scale up to mass production it may lead to a new and inexpensive source of energy."
