RE: Mosquitoes & Bill Gates

A mosquito laser is a proposed device designed to use lasers to kill mosquitoes, primarily aiming to reduce malaria infection rates.
The concept originated in 2007 during a brainstorming session for the Bill & Melinda Gates Foundation, where astrophysicist Lowell Wood, known for his work on the Strategic Defense Initiative (”Star Wars”), suggested using lasers to target mosquitoes.
This idea led to the development of prototypes by Intellectual Ventures, including a system known as the Photonic Fence, which uses infrared LEDs and retroreflective materials to create a detection field monitored by charge-coupled devices (CCDs).
The system identifies insects based on their size and wing beat frequency, allowing it to distinguish between species and sexes, particularly targeting female Anopheles mosquitoes that carry malaria.

The Photonic Fence, as developed by Intellectual Ventures, uses a non-lethal laser to analyze an insect and a lethal laser to kill it, with the latter potentially being a blue-violet laser similar to those in Blu-ray players.
The system is designed to minimize collateral damage by targeting only specific mosquito species and sexes, and it can theoretically kill up to 50 to 100 mosquitoes per second at a range of approximately 30 meters (100 feet).
Despite early media attention and a prototype built from consumer electronics parts, the device remained under development as of 2017 and was not deemed safe for human eyes at that time.

More recently, a new device called the Photon Matrix, developed by a team led by Jim Wong from Changzhou, China, has emerged as a crowdfunded project on Indiegogo.
This device uses LiDAR technology to detect mosquitoes within 3 milliseconds, measuring their distance, orientation, and body size, and then employs a galvanometer-directed laser to kill them.
It claims to kill up to 30 mosquitoes per second, with a range of 3 meters (9.8 ft) for the Basic Edition and 6 meters (19.7 ft) for the Pro Version.
The Photon Matrix incorporates millimeter-wave radar to detect larger objects like people and pets, preventing the laser from firing in their direction.
It can operate on a wall outlet or a rechargeable power bank, with up to 16 hours of use on a single charge.
The device is claimed to be safe for indoor and outdoor use, though its safety certifications and compliance standards remain unclear.
The company plans to begin shipping units in October 2025, with full production expected by March 2026.

In contrast, other products like the Bzigo Iris use a safe, eye-safe laser to mark the location of mosquitoes for easy manual elimination, rather than killing them directly.
Meanwhile, some commercially available devices, such as the LASER HAND Indoor Mosquito Killer, use UV light to attract mosquitoes and electrocute them, relying on physical trapping rather than lasers.
While the mosquito laser concept has evolved from early prototypes to modern crowdfunded devices, the practical deployment and real-world effectiveness of these systems are still under evaluation.
