Nah, lasers too big. It would be a simple birdshot shotgun. Its detection and aiming.
When they are high up, they can be hard to spot and hear.
But a pair of sensitive mic's and a camera designed to look for them could easily be paired with some AR glasses.
I've seen that video a few times, I never got to the part where he wanted to continue the class and pull out a AR-15 and the class is all NOOOO!!!!!! and people start leaving. Holy shit...
When fuel gases (H2 and CH4) for fuel cells are produced from fossil fuels and biomass, there is a high possibility of presence of hydrogen sulfide (H2S). Because H2S can poison fuel cells and cause long lasting damage, it is necessary to rigorously remove H2S from fuel gases before use in fuel cells.
After they are converted into hydrogen, the H2S content can stay between a few ppm to more than 1% depending on the production methods [3], [4], [5], [6], [7], [8], [9], [10], [11]. Research has shown that even the existence of ppm levels of H2S is enough to poison fuel cell components and cause irreversible damage [12], [13], [14], [15], [16]. The international standard for hydrogen fuel quality (ISO 14687) will be mandatory in the EU from November 2021 and currently states a maximum concentration limit of 0.004 ppmv for sulphur compounds [17]. With the potential damage caused by poisoning of fuel cells and particularly stringent legislative requirements, it is vital to thoroughly remove H2S from fuel gases before use.
"Green" or "Non-Green" and climate change isn't even a consideration in the production of H2
Non-Green H2 can't be used without spending a huge amount of extra energy/$$$ (if it's even possible) to remove H2S, making it viable to be used in a Fuel Cell
Killed someone out of gross negligence, and 3 years is to much?
Yeah, don't agree with that. A person lost their life. Not injured. DEAD.
Gross negligence like leaving something on your lawn that is clearly dangerous and then hurts someone. Maybe.
Or you're operating a vehicle unsafely at a jobsite and kill someone by accident.
But you're hired to deal with tools that are DESIGNED to be lethal.
The bar to account for safety is so much higher than typical involuntary manslaughter.
IMO, she should be getting 5+ years, and the producer (hiree) should be facing a year for putting a 26 year old in charge of such a thing.
How much experience could a 26 year old possibly obtain properly to be the one in charge of such a thing.
Apprenticing, sure. But it's negligent on the person hiring such an inexperienced person as well.
