iFixit tears down the Nexus Q: made in the USA, and possibly somewhere else

www.engadget.com
Is it possible to manufacture a sophisticated wireless-capable device entirely in the United States? That's vaguely the suggestion of Google's jet-black orb, launched last week at the search (and now hardware) giant's I/O event in San Francisco. Now, the Nexus Q is just dying to get undressed, and that's...

A supercapacitor in your optical drive: DVD-RW used to burn graphene capacitors

arstechnica.com
Reliable high-capacity energy storage is one of the major challenges we face in developing new electrical technology. From long-range electric cars to backups for variable-output alternative energy sources such as wind turbines, the need for inexpensive energy storage—both long- and short-term—will only increase. While chemical batteries are the primary...

Light Hum: a pure analog theremin that converts rays into electro-grooves (video)

www.engadget.com
Who doesn't love a good theremin spectacle? We Engadgeteers are aficionados of the touchless, variable capacitor musical instrument used in countless '50s space films, so a project by student and designer Danne Woo definitely caught our eye. Woo, who appeared on one of our most popular Engadget shows ever,...

New server-class SSDs from Samsung and Intel reach 800GB, up to 800MB/sec

www.extremetech.com
Solid state drives are becoming more important in the server world. Not only are there significant performance gains compared to hard drives, but the price and capacity are becoming feasible for an increasing number of companies. While spinning disks are still cheaper and larger capacity, the gap is shrinking. The...

Light-based 'Metatronics' chip melts minds, not copper

www.engadget.com
Engineers at the University of Pennsylvania have flipped the switch on a new type of computer circuit. Unlike conventional silicon, the new chip uses light -- not electricity -- to perform its logic. By creating an array of nano-rods, light-flow can be treated like voltage and current. These rods...

Metatronic chip replaces electricity with light, swaps resistors with nanorods

www.extremetech.com
Optical engineers at the University of Pennsylvania have created the first computer circuit where logic is performed with light instead of electricity. Dubbed “metatronics,” this light-based logic could enable smaller, faster, and more energy efficient computer chips.The team, led by Nader Engheta, demonstrated that it’s possible to make resistors, inductors,...

The fast and the flexible: Graphene foam batteries charge quickly

arstechnica.com
RPI.edu There are a variety of technologies available for storing energy, each with various tradeoffs in terms of weight, capacity, and performance. For example, capacitors are fast and lightweight but, despite their name, don't have a large capacity. Batteries can hold more charge, but are heavier and take longer...

MIT researchers develop chip that can harvest energy from multiple sources

www.engadget.com
We've seen a number of different devices that can harvest energy from various sources, but none quite like this new chip developed by a team of MIT researchers. It's able to harvest energy from three different sources simultaneously: light, heat and vibrations. The key to that is a sophisticated...
