Looking for some evidence that we officially live in the future. Here you go: the Brits are "using supercapacitors to create deflector shields for tanks." Zzzzzap!
Essentially, they're working on creating huge bursts of energy to be unleashed whenever a projectile is about to hit a tank or other heavy vehicle. This would deflect any rockets or bullets. It would then be able to quickly recharge. The trouble is figuring out how to get the timing right, as if the burst comes too soon or too late its all for naught.
But still, force fields! Awesome!
