vacuum

AvE tears down a broken Dyson Animal vacuum and its expensive replacement, criticizing the molded plastic, flimsy switches and overall engineering, with his usual profane commentary.

Thunderf00t, a physicist, critically assesses the Hyperloop concept, covering the vacuum, pressure, safety, and cost problems of high-speed tube travel. He argues the media accepted the claims uncritically.

Adam Something argues that the Hyperloop is impractical, covering the costs and engineering problems of running trains in a near vacuum compared with conventional rail and metros. The description admits some wrong numbers in the original cut.
