By now, most of us know the end of Monsters Inc. The Monsters discover that the screams they've been using as a power source are not the most optimized way to do business. Which, you know, is good to find out given the terror they've been puting generations of kids through. Thanks to the adventures of Sully, Mike and Boo, they find out laughter works even BETTER than the sreams. What I want to know, Theorists, is WHY that is and, more importantly, did the Monsters actually make a big MISTAKE?

    I'm shocked that the video didn't mention how hard it would be to consistently make someone laugh. Humor isn't reliable, it's really subjective.

    The "reverse" of a speaker sounds fancy when you say it like that, but it's called..... a microphone!!! And it's really trivial, basically the same as a speaker, definetly somthing a kid could make.

    So it would seem that screams are the non-renewable energy reasource of the monster world. And laughter is the renewable energy source. Do you think they had protests in the monster world to switch to renewable energy, like the human world.

    The reason they don't harvest the energy from adults is because if a kid sees it it's probably their imagination and when the kid grows up the thing the imagined it or forget it. But when adults see it they're going to organize and come flooding in the monster world with swords lightsabers harpoon and guns. It's much more risky to deal with adults then kids. Cuz we're all adults have weapons all the monsters have are the things they were born with. And they are not designed to attack because all they have to do is exists near the kid because everything is scary in the dark.

    Converting sound into electricity? You mean a microphone? Seriously, that description of the kids' project is a decent description of how a dynamic microphone works. And yes, you can use a speaker as a microphone just fine. The quality probably won't be that great, but it'll work.
