Directed Energy Weapon Downs Mosquitos 428
wisebabo writes "Nathan Myhrvol demonstrated at TED a laser, built from parts scrounged from eBay, capable of shooting down not one but 50 to 100 mosquitos a second. The system is 'so precise that it can specify the species, and even the gender, of the mosquito being targeted.' Currently, for the sake of efficiency, it leaves the males alone because only females are bloodsuckers. Best of all the system could cost as little as $50. Maybe that's too expensive for use in preventing malaria in Africa but I'd buy one in a second!" We ran a story about this last year. It looks like the company has added a bit more polish, and burning mosquito footage to their marketing.

Ah, that's a good point, but the counterpoint is that the spayed female mosquito is going to keep attracting males and may keep those males busy enough that, given the short reproductive lifetimes, they miss the chance at fertilizing the eggs of a fertile female. If you sterilize 90% of the females, that may cause the same effect as if you killed 98% of them (similar to a vaccination herd effect). So, not so good to protect you locally but better in the long run. If you have to place the devices where humans can't be because they could accidentally cause blindness, then they're not very useful for direct protection but more useful for limiting reproduction.
That said, I think somebody else put their finger on how it will fail - selection pressure will change the common beat frequency for the female anopheles mosquito. It's probably related to size, and this will therefore select for a different size of female by letting them survive. Hopefully a production version of this thing can take a firmware upgrade that changes the targeted frequency range.

An improvement suggestion (Score:5, Informative)
An improvement in both safety and efficiency would be to use two lasers, each about 60% as strong as the currently used single one.
The targeting computer would aim both lasers at the target frying it even faster than now. But, should one of the "canons" miss, or should an unintended target come into one of the beams, the "collateral damage" will be much smaller, because the other laser will not be aimed at the same spot.
I think, the military lasers should use the similar technique — use multiple weak lasers frying the same target from dispersed locations. An unintended object (such as a civilian airplane) flying into any one of the beams will be safe, and taking out the entire installation will be much harder for the enemy. The set can have a cumulative power twice (or more) than is required to destroy one target, while each individual beam is still (relatively) harmless.
When "healthy", such a setup will be able to destroy multiple targets at a time, and the enemy will only be able to reduce its capacity gradually, rather than all at once.
