Sun Microsystems has received $44 million in funding from DARPA to work on a way to connect multiple silicon chips using lasers instead of traditional wires.

Wires are a major bottleneck in multi-chip systems today because they slow down the rate at which the chips can communicate. Sun is now aiming to fix that problem by switching out the wires for tiny lasers. The company believes that if successful, the new technology could allow the chips to work up to a thousand times faster.

Unfortunately, Sun is only giving the project a 50% success rate, so we may not be seeing tiny lasers inhabiting our computers any time soon. Hopefully they can get it done though, because as Alan Huang says, “This would be a way of breaking Moore’s Law,” and we’d love to see some blazing-fast computers in the near future.

Today’s heads-up displays worn by soldiers are bulky and probably quite uncomfortable. DARPA is seeking to solve all that with contact lenses that sport a display to overlay graphics and information on top of the soldiers’ vision.

Specifically, the agency is looking for “information on technology areas for the creation of micro- and nano-scale display technologies for the purpose of creating displays that could be worn as transparent contact lenses”, and they want that information within three to five years.

This sounds like a very ambitious project, but with DARPA behind it maybe, just maybe, we’ll actually see it come to life. Perhaps this is a job for UW scientists and their contact lenses with circuits?

DARPA is funding research at the University of Wisconsin at Madison aiming to develop an energy-efficient, heat-resistant mechanical nanocomputer.

The scientists are essentially trying to create a mechanical version of today’s silicon computer chips that’s able to perform in extreme environments such as space, car engines, and battlefields. Instead of using transistors and other electrical components, a mechanical nanocomputer would rely on gates, pillars, levers, and pistons to perform calculations.

The mechanial parts mean that this computer is more rugged and can operate at much higher temperatures. It also uses less energy, mainly due to the fact that it doesn’t need a power-hungry cooling system as it produces very little heat unlike its electrical counterpart.

Although mechanical computer designs have been around for a while, this is the first attempt to squeeze such a computer into a tiny package. Imagine itty bitty parts moving inside of your cell phone when it needs to calculate something. Although this new tech probably won’t be used in our gadgets, it could prove to be very valuable in demanding space and military applications.

The Defense Advanced Research Projects Agency (DARPA) will soon award a contract for development of an unmanned aircraft that is capable of staying in the air for up to five years at a time.

DARPA’s project, called Vulture, aims to create a craft that can fly uninterrupted over an area for extended periods of time while performing intelligence, surveillance, reconnaissance, and communication missions. Read more »

Dean Kamen’s “Luke arm” has, unfortunately, arrived at the end of its two-year funding. Its fate now rests with the Defense Advanced Research Projects Agency (DARPA), which will hopefully allow the project to continue and provide more funding.

If DARPA gives the green light, the Luke arm (yes, named for the prosthetic of Luke Skywalker in Star Wars) will begin clinical trials. Pending those and the approval of the FDA, veterans could have a chance at wearing this arm by next year. Read more »
