Here’s a design to stop global warming
Here is one from Mr Yanagisawa
https://www.behance.net/gallery/1902587/Cyclus-Step2
It’s just 2 planetary gears on a spring.
Here is a 100 to 1 planetary gear made on a 3d printer:
2 of these 100 to 1 planetary gears stacked on top of each other will make 10,000 to 1 and will require ceramic bearings inside the planetary gears to move with a spring.
A mantle clock spring has 30lbs of strength so the planetary gears must have less than 30 lbs of strength.
A simple motor and USB and someone saved the world for millions of people
This will let people have a fan in extreme heat alerts and will let people make calls.
This product will save millions of lives.
I hope someone will make this device
