New Laser System Targets Mosquitoes
An anonymous reader writes "In the Cold War the so-called 'Star Wars defense system' proposed using lasers to destroy incoming Soviet missiles. In a 2007 brainstorming session aimed at combating malaria, Dr. Lowell Wood, the architect of that system, proposed modifying his original idea to kill mosquitoes. The cover of today's Wall Street Journal contains an article that highlights this initiative as well as a few others, like using a giant flashlight to disrupt mosquitoes' vision and using the insects to vaccinate, in the war against malaria. The system is intelligent enough to avoid noncombatants like humans and butterflies and can even tell the difference between females, the blood-drinkers, and males. My favorite quote: 'We'd be delighted if we destabilize the human-mosquito balance of power.'"
TFA is a bit thin on details, I wonder how the performance of this system compares to one of the numerous CO2+odor attractant trapping systems already in use. Frickin lasers(pew pew pew) are certainly cooler; but the whole exercise is rather silly if a simple mechanical system that runs on propane and pheromones is more efficient.
If you read David Brin's "Earth", you will note that there is an explanation of how "Star Wars" technology was modified to control infestations of africanized bees(killer bees) in local apiaries. The book was published in May of 1991.
The premise was that honey bees flapped their wings at a lower frequency. Targeting the higher frequency enabled the device to precisely target only the invading killer bees.
I know a guy who owns property in rural Alaska (a very swampy area), and in summer the mosquitos are terrible. He has been experimenting with the propane powered mosquito traps, and has found that he can't leave them out overnight. The problem? They catch so many mosquitos that the trap fills up and causes the whole thing to burn up.
His solution so far has been to run 3 of them at once for short periods of time during the day when he can periodically empty them.
I'm not sure how much propane they use, but he has also complained about that. Since he has to fly it all in, and propane bottles aren't the most efficient use of weight/space in a plane. I also wonder about the environmental effects of using those on a large scale. How much C02 do they actually produce?
I was thinking about that a while ago.
A rotating laser leveling system like the dewalt uses dual lasers with a 600 feet range and rotates faster then the camera can recover. I was thinking of a way to widen the beam on a vertical axis to flood the cameras I first attempted to insert a filter but lacked any that could readily be used without modification. I then attempted to mount mirrors at various angles but the beam was too narrow.
Then a friend came around with a cop who took him to my house after his car was broken down and stranded on the road. The police have cameras now that read license plate numbers and they can press a single button and it retrieve registration information from it. Anyways, his video display went blank when he pulled in the drive and asked me what I was doing. I said rigging an automatic gate opener and attempted to claim I wanted to open a gate and the garage doors when I entered the drive way plus maybe turn a few light on.
The cop then told me that it was illegal to mount lasers like that to a car. It's covered under the radar jammer laws in which a cop uses laser radar. He also mentioned that it blinded his cameras in the cruiser which is what attracted him to me. He was cool with it but warned me that I could be in some trouble. I mention this because if you do attempt to do it, keep in mind that it might already be illegal in your area and if everyone else is without it, it isn't going to be hard for a cop around you to figure out you have something like that. Especially at night when you can't see them coming.
On the other hand, if you do get something figured out, let me know because I'm still interested. I just don't want a ticket or jail time over it.
