It appears someone is beginning to take the human war on mosquitoes seriously.  The fact that it was so readily cobbled together is rather good news. It suggests that the next order of magnitude is possible and that works for me.  <\/o:p><\/span><\/span><\/div>\n

The needs of the modern consumer are simple.  He wants to sit in his back yard in a fairly open place on a summer evening and relax with a beverage in hand.  It takes little to make him happy.<\/o:p><\/span><\/span><\/div>\n
<\/div>\n
Lasers can protect a large cube around that consumer as a minimal design plan.  <\/o:p><\/span><\/span><\/div>\n
<\/div>\n
Everyone else in the world wants the same protection, but right now a simple fifteen by fifteen by ten cube will satisfy plenty of paying customers who want their patios back for the whole summer.<\/o:p><\/span><\/span><\/div>\n
<\/div>\n
Establish that market and the crest will follow naturally as need and funding dictates.<\/span><\/o:p><\/span><\/div>\n

Using Lasers to Zap Mosquitoes<\/b><\/o:p><\/span><\/i><\/div>\n

TED \/ James Duncan David<\/span><\/i>At the annual TED conference in Long Beach, Calif., Nathan Myhrvold presented a laser, built using common consumer electronic parts, that shoots down mosquitoes.<\/span><\/i><\/o:p><\/span><\/i><\/div>\n
Can consumer electronics be used to combat malaria?<\/o:p><\/span><\/i><\/div>\n
Nathan Myhrvold, Microsoft<\/span><\/a>\u2019s former chief technology officer, thinks so. His company, Intellectual Ventures<\/span><\/a>, has assembled commonly available technology \u2014 parts used in printers, digital cameras and projectors \u2014 to make rapid lasers to shoot down mosquitoes in mid-flight<\/span><\/a>. If bed nets are the low-tech solution to combat the deadly disease \u2014 caused by a parasite transmitted when certain mosquitoes bite people<\/span><\/a> \u2014 the laser is a high-tech one.<\/o:p><\/span><\/i><\/div>\n
He gave the first public demonstration of the laser, which was cobbled together from parts found on eBay<\/span><\/a>, at the annual TED conference<\/span><\/a> in Long Beach<\/st1:city>, Calif.<\/st1:state><\/st1:place>, which features lectures and demonstrations by experts in a wide range of fields, including technology, politics and entertainment.<\/o:p><\/span><\/i><\/div>\n
After hundreds of mosquitoes (which were kept in the hotel bathroom until showtime) were released into a glass tank, a laser tracked their movements and slowly shot them down, leaving their carcasses scattered on the bottom of the tank. While the demonstration was slowed down for public viewing, Mr. Myhrvold said that normally the lasers could shoot down anywhere between 50 to 100 mosquitoes per second.<\/o:p><\/span><\/i><\/div>\n
Mr. Myhrvold played a slow-motion recorded video<\/span><\/a> that showed what happened to a representative mosquito. As the insect flew, a sudden light beam struck it, disintegrating parts of its body into a plume of smoke. It fell, even as its wings continued to beat.<\/o:p><\/span><\/i><\/div>\n
Mr. Myhrvold said the software detects the speed and size of the image before deciding whether to shoot. It would reject a butterfly or a human, for example, and more powerful laser blasts could be used for locusts. In regions afflicted by malaria, the lasers could be used to create protective fences around clinics, homes, or even agricultural fields as a substitute for pesticides.<\/o:p><\/span><\/i><\/div>\n
The idea was born from a 2008 brainstorming session held on strategies for killing malaria-bearing mosquitoes, a particular interest of Mr. Myhrvold\u2019s friend and former boss, Bill Gates, who has made the illness one of priorities of the Bill and Melinda Gates Foundation<\/span><\/a> (to the point that Mr. Gates released mosquitoes into the audience<\/span><\/a> at last year\u2019s conference).<\/o:p><\/span><\/i><\/div>\n
The idea of lasers \u2014 a miniature \u201cStar Wars\u201d weapons system<\/span><\/a> \u2014 was thrown into the mix. \u201cEveryone was like, \u2018C\u2019mon, be serious,\u2019\u201d Mr. Myhrvold said in an interview after the demonstration. After doing a little bit of research, he said, his team concluded that \u201cthis is feasible. We can actually do it. So we did.\u201d<\/o:p><\/span><\/i><\/div>\n
The breakthrough relied on understanding how the technology that guides the precision of laser printing could be combined with the image-detecting charge-coupled devices, or C.C.D.\u2019s, used in digital cameras and powerful image processing software. Mr. Myhrvold said he thinks there is particular potential in the Blu-ray laser technology, because blue lasers are more powerful than red ones and there are a lot of them being made cheaply now.<\/o:p><\/span><\/i><\/div>\n
He estimates that the devices could potentially cost as little $50, depending on the volume of demand. However, his company would not manufacture them. Rather, it built the technology mostly as a proof of concept. (Among other things, his company is also working on cooking technology<\/span><\/a>.) Other companies would have to take the laser technologies to market, so the timeline for seeing the lasers in common use is uncertain.<\/o:p><\/span><\/i><\/div>\n
The laser detection is so precise that it can specify the species, and even the gender, of the mosquito being targeted. \u201cThe women are bigger. They beat at a lower frequencies,\u201d Mr. Myhrvold said. Since it is only the female mosquitoes who bite humans, for the sake of efficiency, his system would leave the males alone.<\/o:p><\/span><\/i><\/div>\n
