Most of the Chinese DIY Inventions featured in the Atlantic are not technically inventions, but they are creative and determined home-brews of existing technology, constructed by industrious people who happen to be Chinese. What makes these constructions awesome besides their creators’ persistence is how awesomely dangerous most of them are. Homemade motorcycle airplane? Check. Submarine? Several, actually. What about a helicopter whose motor you start the same way your great grandpa did in proud service of the RAF when the Tommys battled the Prussians to be Lords of the Skies over Verdun? Hell yes. And don’t mess with the dude (frame #17) who made a multi-chamber cannon mounted on a wheelbarrow to defend his farm.
