The "Perpetual Motion" Pump That Actually Works
On a usual day, Steve Mould's catalog of science videos draws somewhere under three hundred thousand views between them. Right now it is running well above that, and nothing new went up this week to explain it. The older videos are doing it on their own.
The busiest of them is "The "Perpetual Motion" Pump That Actually Works," about ram pumps. The description calls them probably his most requested topic, and says building a transparent one that worked was really hard. The quotation marks in the title matter. A ram pump uses a stream's own flow, with nothing plugged in, to push part of the water uphill, which is why it looks like cheating and isn't.
Close behind is "This Device Goes Past Equilibrium," on counterflow heat exchangers, which can swap the temperatures of two liquids. Then comes a left turn into biology with "Hooded Seals are Really Weird..."
He is the largest channel by subscribers among similar science channels. Hank Green is the one having a notably busy stretch there.
