I have been wanting to make this laser FOREVER and i could have made a hour long video on it. But dont worry, I have much more planned for this laser!

There were never any planes in danger and I can prove it with science. First of all, we never turned the beam on more than 4 amps (50 watts)because we were having cooling issues and couldn’t really monitor it up on the car.. (we tried 6 amps once but it was too bright.)
So assuming the beam stayed perfectly collimated, the beam would have an area of 430 square centimeters. If the laser was running at 25% power (4 amps/50 watts) that would be about 110mw/cm2 from the telescope. However, your pupil is only half this size fully open, so a pilot could theoretically receive a 50mw/cm2 exposure. A decent amount, but you have to remember even the smallest plane is traveling 150 miles per hour which would limit total exposure time to only 3ms( time it takes to cross a 9 inch beam). That puts it at the cusp of the maximum exposure limit, which is defined as “about 10% of the dose that has a 50% chance of creating damage under worst-case conditions.” Here is the chart im referencing https://en.wikipedia.org/wiki/Laser_safety#/media/File:IEC60825_MPE_W_s.png
So even under perfect conditions, this would still be 10x less than the exposure that carries a risk of damage. That’s assuming perfect conditions, but in reality it was a hazy night, the laser would not be perfectly collimated, the atmosphere would distort the beam, the windows in the airplane would deflect some of the beam, unless the pilot was staring directly at the beam they would receive a smaller dose, I tried to keep the beam moving when up in the sky, and most planes are moving faster. all of this meaning the pilot would be exposed to a much lower amount of laser energy in the real world than under perfect conditions. even at full power this laser is still within the safety factor of the maximum exposure limit. Plus do you know the odds of hitting a plane with a laser when your trying not to? just pick a random star in the sky and wait for a plane to fly over it.

“The bread is holding out wel… oh no wait the bread is on fire”
2020 in a nutshell
So cool. Queens on fire!
when i have seen the cooper penny i was like: I dont want to use a laser ever again.
It's dangerous weapon, not toys! It will causes hire in neighborhood or hurt someone accidentally.
How is this legal?
No harm to insects would be done….
uhm R I C K Y uh he sels lezres
Bro… Im pretty sure you’re on a list somewhere now…
A couple of lists actually..
You are crazy my friend
"some aliens just got a vibe check"
Where do I get this laser?
In 13:52 you can see the laser burn everything in its path.
My electric scooter is 250 watt lol
Haha Nice
For the Mavic mini do you need a drone license
I really enjoy your videos such a cool guy wish I had more buds liked you I like a think tank
@ 8:27 when there is the small explosion, I slowed the video playback speed down to 0.25 to see the explosion better. I noticed what looks to be a drone of sorts being flown at the gate. Was this the new Mavic, or something else?
Alle Tiere im Lichtbereich werden damit getötet! 5 dislike!
QUEEN´S ON FIRE! QUEEN´S ON FIRE! sorry queen nothing personal…………….BAM,BAM,BAM!
And on behalf of our queen your karma will come believe me I guarantee it
At 8:29 when you claim it burnt instantly I slowed the footage and it was a firework fired at the board not a laser that made the explosion its clear to see slow it to -0.25 you clearly see it now I'm questioning if your an honest guy or a down right good actor who has everyone fooled there's other things that give it away to
Who else wants him to do uranium
welp seems AT-RTs are real now
Your wild and crazy man and I'm enjoying the videos. Exspecially the aluminum vs the glass cubes. Just keep in mind that rocks can explode under enough heat and your head was kinda close to it. If you blow your head up then who's cool videos will I watch. Be safe man and keep burning!
id like to see you up scale this to 10 000 watt.
Hey backyard scientist I think I have ur zinc penny
not street legal?
So we got from a laser that can penetrate a solid rock into a childs party piece. I'm confused at what was the point.
"oh noooo… The cameras drunk :("
