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.

      First: What's more impressive than the lasers that fry* the mosquitoes is the targeting and detection system that drives this crazy thing. Many people are looking at this and wondering how you pick out your targets. The system first scans the surrounding space and *listens*. What it is listening for is quite interesting. See, Malaria is an interesting disease because only specific mosquitoes carry it, and only the females. Since there could be many side effects to zapping any insects within range, or even any mosquitoes (regardless of species or gender), the laser targeting system listens for the precise wingbeat frequency of the female [wikipedia.org] Anopheles Stephensi mosquito and then zaps only those.

      *Technically speaking, the mosquitoes will not be fried in the final product. In addition to potential danger to other occupants of this system's effective bubble, it is planned for deployment to very poor areas of the world where electricity will likely be at a premium. As a result, they are also experimenting with the minimum amount of energy a laser strike must possess to render the mosquito infertile, because that interrupts the cycle necessary for Malaria transmission between humans.

              The sarcasm between the lines here is of course that some species by being cute are somehow magically important and we should intercede at great cost and labor to do whatever we can to prevent their extinction, regardless of the accepted fact that 99% of all once extant species are now extinct. Humanity is so conceited about how it subjectively assigns meaning to niche species that it thinks that a healthy biosphere is one frozen in time where nothing changes, nothing adapts. Never mind that without mass extinctions in prehistory, there would be no animal life as we know it whatsoever.

              I hope so. It also made me wonder about Poison Ivy. That plant is damned lucky that it is hardy, because I can't think of a worse thing to happen (evolutionarily speaking) than to develop a defense which is exceptionally annoying to a sentient creature with access to landscaping equipment.

              I'm sure it worked great as a defense for creatures whose only real option was to 'Avoid that greasy trefoil', but once you add a machete and herbicides into the mix it's amazing how fast a true advantage is turned into a significant disadvantage. I hate that plant so much that I'll cut it off at the roots if I'm just walking through the forest and happen to see it.

              Odd considering that other plants (and domesticated animals ancestors) won the genetic lottery simply by having a useful feature which humanity exploited.

        I think this would be a sudden enough change that evolution wouldn't have time to have any effect. It'd be a pretty radical change over a short period. Unless there are currently large male mosquitoes whose wings beat at lower frequencies, there won't be many mosquito Casanovas for the skeeterettes to find. And since they use wingbeat frequency to find each other, the females will think it's another female anyway.

        But, if the skeeters do evolve, there's always a firmware update.

    This lazer device use was banging around in the early 1980's. A couple of grad students from Florida created it. I don't recall how they were able to track the bugs. But they also "tuned" the lazer so that it lasted just long enough to only vaporize the wings. There's just one problem with this device, if the target is between the lazer, and a person's eye.

    This shows that IV is quite capable of producing actual, useful products. Its business model is not limited to patent licensing revenue, which makes it more like, say, IBM, than a typical patent holding company.

    Maybe, just maybe, IV is not the evil parasite that many on Slashdot made it out to be. In fact, it seems to be in the business of shooting evil parasites with lasers, which is pretty cool.

    You'd take a pan and tilt servo controlled laser, and put sound sensors around the laser. Move the laser towards the loudest noise, fire when the noise is equal on the sensors. Bingo, dead mosquito. Just like a sun tracker!

    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.

The island where I vacation every year in Candada is rife with the buggers. you can see dozens of swarms of skeeters the size of a small house (the swarm not the skeeters) hovering near the tops of the treelined fields at dusk, and the flies along the beach in some areas make it impossible to inhabit without a beekeepers suit (they bite through tshirts). One year I had to run a 1/4 mile off the beach because I was being swarmed by the flies. I could feel them bouncing off the back of my head as I ran... not fun times.
