New silicon-based battery good for "thousands of hours" developed in Israel

If the promises hold up under real-world testing and some of the remaining issues get handled, this could be monstrously huge:

A new kind of portable electrochemical battery that can produce thousands of hours of power – and soon replace the expensive regular or rechargeable batteries in hearing aids and sensors and eventually in cellphones, laptop computers and even electric cars – has been developed at Haifa’s Technion-Israel Institute of Technology.

The unique battery is based on silicon as a fuel that reverts to its original sand. The battery can also be left on the shelf for years and inserted into a device to provide immediate power

Battery technology is the brick wall in front of a whole host of advancements these days. Truly practical electric cars, powered prosthetic devices, wearable computing devices, and all sorts of other things are all held back by the lack of a sufficiently powerful and light power source. There’s a number of companies working on this issue but this is the first one that I’ve heard of that’s both close to a solution and using silicon as the basis of their approach. Fascinating stuff.
