Like Lewis and Clark, I find mosquitoes to be doubly pestilent, as the little red bumps they leave behind are about as annoying as remembering how to spell their name. An article in the current Technology Quarterly from the Economist comes as a soothing poultice:
Researchers at Intellectual Ventures, an innovations company established by former Microsoft executives in Bellevue, Washington, have developed what they call a photonic mosquito fence. It has a series of posts, each of which is equipped with a cheap camera and a light bulb (which will be swapped for a light-emitting diode in future versions). The cameras are connected to a central computer. When a camera detects movement, the computer analyses it to see whether it is consistent with the behaviour of a mosquito. If it is, then the computer trains a laser onto the insect and blasts it into oblivion.
The article also describes an infra-red curtain designed to keep mosquitoes out; not as satisfying as conflagrating the little beasties, I suppose, but in any case more effective than the mosquito net I can't seem to find the time to install over my bed.
