While this laser beam isn’t on the shark’s fricking head, it is firmly attached to its dorsal fin with a temporary clip. Why did someone go and clip a powerful green laser to a shark? Because they can. Duh.
During the shooting portion of the pentathalon at this year’s summer Olympics in London, athletes will be shooting with laser pistols instead of airguns. The new laser pistols are calibrated to feel and recoil just like an airgun, only they’re safer and cheaper. Safe and cheap. That’s exactly what I want in my sporting competition.
On 15 March, the 192 laser beams of the National Ignition Facility (NIF) at Lawrence Livermore National Laboratory in California, fired a record 1.875 megajoule shot into the laser’s target chamber that was focused to a final 2.03 megajoules. The shot, which was just a demonstration, nonetheless represents a milepost in an effort to get past the break-even point in coaxing fusion energy from a tiny frozen fuel pellet.
Fusion is awesome stuff, but currently it isn’t efficient in that it takes way too a whole hell of a lot of energy to end up with less than you had to begin with. But with the magic of a magnetic field and “lasers”, scientists could sustain a fusion reaction long enough to get an actual energy return. Hooray!
As if riot police don’t already have enough fun toys at their disposal, cops in the UK are currently testing “laser” rifles that when pointed at someone, can temporarily stun and blind them.
