Laser Kills Mosquitoes Like Brin's Bee Zapper
Physicists have created a laser weapon that targets mosquitoes. It is hoped that by finding an effective weapon against mosquitoes, the incidence of malaria could be reduced. Today, malaria kills about one million people every year around the world.
(Mosquito Zapper)
"We'd be delighted if we destabilize the human-mosquito balance of power," says Jordin Kare, an astrophysicist who once worked at the Lawrence Livermore National Laboratory, the birthplace of some of the deadliest weapons known to man. More recently he worked on the mosquito laser, built from parts bought on eBay.
According to a recent article in the Wall Street Journal, the device is the brainchild of Lowell Wood, an astrophysicist who worked with Edward Teller, father of the hydrogen bomb and architect of the original plan to use lasers to shield America from the rain of Soviet nuclear arms.
Dr. Wood suggested that the old "Star Wars" laser shield idea could be used to zap mosquitoes.
Demonstrating the technology recently, Dr. Kare, Mr. Myhrvold and other researchers stood below a small shelf mounted on the wall about 10 feet off the ground. On the shelf were five Maglite flashlights, a zoom lens from a 35mm camera, and the laser itself -- a little black box with an assortment of small lenses and mirrors. On the floor below sat a Dell personal computer that is the laser's brain.The glass box of mosquitoes across the room is an old 10-gallon fish tank. Each time a beam strikes a bug, the computer makes a gunshot sound to signal a direct hit.
To locate individual mosquitoes, light from the flashlights hits the tank across the room, creating tiny mosquito silhouettes on reflective material behind it. The zoom lens picks up the shadows and feeds the data to the computer, which controls the laser and fires it at the bug.
Not only can the laser target a mosquito, it can also tell a male from a female based on wing-beat.
I'd hesitate to credit this idea to Dr. Wood. Instead, consider David Brin, who wrote about a laser-based bee zapper in his 1990 book Earth:
At least the bee zapper was working. For years their hives had been under siege by Africanized swarms, seeking to take over as they had everywhere else in the area... But a few weeks ago Claire had found a net reference by a fellow in Egypt, who'd discovered that the African strain beat their wings faster than the tame European variety. Burrowing into archaic TwenCen military technology, he had adapted sensor-scanning designs from an old defunct project called "Star Wars..."Like a glittering scarecrow, the cruciform laser system watched over her squat hives. When she had first turned it on, the surrounding fields had come startlingly alight with hundreds of tiny, flaming embers...
