You will find it here, and clicking through the side show of previous innovations, and their history, is fascinating. I enjoyed this part of the accompanying write-up from Hugo Lindgren:
On his blog, Marginal Revolution, Cowen furthers his point by declaring sarcastically that “there is no great stagnation” and providing links to silly products or applications of technology, like a machine that tosses popcorn into your mouth from up to 15 feet away. It’s called The Popinator. Someone thought this up — first as a marketing stunt, but now they’re trying to make an actual product. Someone also thought up the Ostrich Pillow, a big, comfy thing that you can stick your head into and nap in public places. My favorite of Cowen’s collection is a gun for shooting salt pellets at insects — the Bug-A-Salt! I also like the remote-controlled cockroach, a technology which has not yet been commercialized. But maybe one day.
Cowen’s point is that under the hood of our hallowed free market is a bazaar of nutty, half-cocked ideas which do not advance the greater cause of humanity one tiny bit. But there’s another interpretation, too, which is: The sheer volume and range of these inventions demonstrate a rapidly growing range of problem solvers with the tools to turn their ideas into tangible things.
