UM students make cheap and portable solar charger / light source for developing nations

Solar power is the most egalitarian of all energy sources, yet residents in many parts of the world still lack access to electricity. Three University of Michigan engineering students have created an affordable solution to this problem -- to the delight of camping geeks everywhere -- with the Emerald, a portable solar panel that does double duty as both a cellphone charger and personal light source. We've seen the personal solar panel idea before, but the price of entry made it an untenable solution for developing nations. Solar-powered light bulbs have been around for a while too, but the Emerald's light lasts for eight hours on a charge (as opposed to the bulbs' two to six hours), and it's able to fully charge a phone in the same time it takes an outlet to do the job. They aim to sell the device for the low, low, price of under twenty bucks for customers in the developing world, which is 90 percent cheaper than other solutions and 100 percent more awesome.

Memristor- A groundbreaking Technology

Researchers in computer science and neuroscience have been steadily working to uncover the core design principles underlying intelligent behavior, and inventing key technologies needed to build machines that emulate it. Now, with a recent discovery at Hewlett-Packard Labs, the field is poised to make a massive leap forward by being able to finally build large, brain-like systems running on inexpensive and widely available hardware.
In May 2008, USA’s Defense Advanced Research Projects Agency (DARPA), with a track record in promoting high risk, high reward projects (such as the precursor of the Internet), jump-started the process via the Systems of Neuromorphic Adaptive Plastic Scalable Electronics (SyNAPSE) initiative. The goal of this research program is to create electronic neuromorphic machine technology that is scalable to biological levels. SyNAPSE is a complex, multi-faceted project, but traces its roots to two fundamental problems.
