It’s a prime example of unnecessary complexity and risk. You get comparable results from a box fan pointed at a wire screen (mosquitoes get trapped on the mesh by the airflow), but nobody writes breathless articles about a box fan.
You can install a mosquito killing laser outdoors and have a large area of no mosquitos. How effective is a fan for that use case?
Given that the laser is pure vaporware, I’d say it’s infinitely more effective.
It was patented by Intellectual Ventures so was probably never going to be a real product. When the patent expires maybe someone will touch it.
IIRC it's nearly impossible to ensure that the laser (or its reflection from something!) never ever hits the eyes of people, and so it's not a viable product due to liability issues.
A system that zaps mosquitoes indoors (for example in the bedroom) is at least as valuable as one that zaps mosquitoes outdoors. Also easier & safer to implement. Activate it and close the door to the room, after clearing out pets. Let it run until it beeps. Re-enter toom. Sleep soundly without all the damned buzzing and biting.
Much safer would be to use directional speaker, which would "hit" mosquito with frequency that corresponds to wing length and damage it.
Making it human safe with light curtain drives cost and as someone already mentioned it is patented. So it’s an expensive product for riches with integrated patent troll lawsuit. Not good starting situation for development.
