Okay, so this doesn't quite fall under the purview of consumer electronics or gaming, but it DOES qualify as science-fiction. Well, except for being real. TechEye reports that the British Army is working on developing a force-field to protect their vehicles from anti-tank rockets.
The force-field works via a super-charged electromagnetic field. Super capacitors are built into the armor and filled up with “huge amounts” of energy. When a threat is detected, the energy is discharged to deflect the missile. The field would only be up for a short time, so the timing will have to be very exact.
Scientists working on the project believe that the technology will be perfected within about 10 years. The goal is to use this new deflection system to reduce the weight of armored vehicles by up to 70%. Pretty badass, right?
