Making a battery that doesn’t fail fast has long been a Holy Grail of technology. Mobile devices that require a lot of energy, such as mobile telephones, digital cameras, and notebook computers, usually use rechargeable lithium ion batteries. The problem is that their capacity is dismal. A notebook computer, for example, usually runs only about two hours.  Now, a research team in Korea has developed a new material for anodes, which could lead to a new generation of better batteries. The team used highly porous silicon to craft anodes that would attract more lithium ions. In addition, the silicon anodes make the lithium ions travel faster, meaning quicker charges when it’s necessary to plug in for more juice.

You can't be serious? If you can't tell a recorded disc from an original one with your bare eyes you need to check your glasses.

Electronic gyros are nothing new, they've been around in r/c helis for several years. And they're not very expensive. Cheapest goes for 20 bucks.

Umm.. the difference between a pressed(original) cd and a copy(burned) is that a pressed cd's data (0 and 1) are represented by physical pits and peaks whereas a burned cd's information is represented by burned (reflective and not reflective) marks on a flat plain. Make a system to differentiate peaks (which are reflective, but does not reflect into the target sensor) from non-reflective burn marks. Then you can tell which is a copy, and which is an original.

Great another way to entice road rage... turn the mobile off while blocked in traffic.
