How to kill a mosquito

How to kill a mosquito at 30 feet

Interesting question… Are we talking vaporize, ignite, or heat up until death for the mosquito? I’ll assume we want to minimize damage to surroundings so let’s just heat them up till they stop functioning. We’d need to figure out the temperature at which a majority of mosquitos will die. Since they seem to love hot weather, let’s assume we need to hit 100°C for them to fry. Estimating the average absorption coefficient for a mosquito when illuminated with the spectrum of your favorite LED source (50% of incident radiative power absorbed?), cross sectional area presented to the beam (1mm2?), and mosquito heat capacity (likely somewhere near that of water, 75.3 J/mol.K), and average weight (2.5mg).Another limiting factor will likely be time-on-target for the beam. According to Wolfram Alpha the max speed of a mosquito is 1.4km/h or 0.39m/s, which means a transit time of 0.26second to fly through a 10cm diameter beamFrom 2,3,4 we can determine the radiometric power needed.

Solar Decathlon

Solar Decathlon

The U.S. Department of Energy Solar Decathlon is a collegiate competition made up of contests that challenge student teams to design and build full-size, solar-powered houses. The winner of the competition is the team that best blends design excellence and smart energy production with innovation, market potential, energy and water efficiency. Simply put, there’s nothing else like it. In 2009, we installed a low voltage distribution system to control the lighting and peripherals in the Alberta/University of Calgary entry. Team Alberta came in 6th place out of 20 contestants.
