Laser-wielding device is like an anti-aircraft system for mosquitoes

> "Importantly, the device additionally uses millimeter-wave radar to scan its field of view for larger objects such as people and pets. If any of these are detected, its mosquito-zapping laser will not fire."
I note the startup doesn't actually disclose the laser output power anywhere, or what regulatory class that power level falls in. It's federal law[0] that commercially-sold lasers are labelled with this information.

> 5 milliwatts is wimpy. We can do better.
A 1-watt laser is an extremely dangerous thing. It’s not just powerful enough to blind you—it’s capable of burning skin and setting things on fire. Obviously, they’re not legal for consumer purchase in the US.
Just kidding! You can pick one up for $300[1].

and there are things that can be done.
heat and motion detectors that disarm the system if people/pets are present fields of fire that are above 99.999 % of peoples eyes fields of fire very close to walls, where mosquitos alight, but it is almost impossible to get in the way for humans multiple laser turrets that indivualy dont have the power to hurt a human badly, but can zap a bug through co ordinated action.....perhaps set up outdoors with artificial breath and infra red bait traps to bring the mosquitos above a crowd. more robust systems to be used in agricultural contexts. this will be about comfort and protecting vulnerable populations, mosquitos/other bugs wont be going anywhere, chemical control has proven to cause ecological probelms worse than the bugs, and the attempts at useing biological methods is only a partial solution.
A human eye being transparent up to the fragile retina, yes, a laser would penetrate the eye and be concentrated in an extremely small spot on the retina. That's exactly the reason why we have safety around lasers, and why everything above 5mw is strictly for enclosed use. 40 watts shot at random in the void is definitely dangerous by all measures.
I’d want to see some third-party testing around eye safety before putting this in my home.
Instead of laser, they should have made a mechanical hand with fly zapper, fragile/soft enough to not injure people and pets, yet strong enough to kill mosquito. Or even like in that movie where kung-fu master catches a fly using chopsticks :)
This isn't the best example, how is it supposed to hit your retina if your eyes are closed?
Microsoft alum fights malaria by zapping mosquitoes with lasers | ZDNET https://share.google/qd3yWi72Zk9yRyxoh
"The concept of a laser-based mosquito defence system took off back in 2007, when astrophysicist Lowell Wood (one of the architects of the USA's famous Reagan-era "Star Wars" missile defence initiative) raised the idea of a smaller, mosquito-targeting laser system at a Bill & Melinda Gates Foundation brainstorming session on eliminating malaria.
Over the following years, prototypes were built, using freely available parts from cell phones and laser printers. A device was patented and demonstrated by a company called Intellectual Ventures, which was more interested in owning the patent than making a product. "
I really hope that after copyright protections (insanely long, IMO) get revamped in the LLM aftermath, we start focusing on patent law. Patents were always in my mind a way to protect small_inventor from big_bad_corp, and give them a breathing room to get a product to market. We should really focus on this, and make patents moot as long as a) a working prototype is not demonstrated, b) the patent holder doesn't pursue the tech, c) a small domain-specific timeframe (less for medicine for example) and d) it's really really generic (i.e. a method to have LLM agents work in a loop - no, bobby, everyone can do that.)
The fact it doesn't do houseflies is a huge downer though.
