Re: HHO gas vs perpetual motion

1) Time is homogeneous.
2) Noether's theorem.
3) Mass-energy is locally conserved.

Anybody who is sufficiently crazy to store a 2:1 v/v mixture of hydrogen and oxygen deserves to die that loud messy death. The ignition threshold is 0.02 millijoules. A fat cosmic ray can set it off.

Some people go cute by snapping a pre-mixed methane or propane gas-oxygen burner by turning off the gas first. Do that with oxyhydrogen and like as not you'll be picking pieces out of your hide after the burner head ruptures. Oxyhydrogen has a tremendous LEL-UEL range, 4-94 v/v-%. It has the highest flame velocity of any gas- dry flame arrestors are not a barrier to propagating ignition.

Hypography?

Hypography [n.]: A combination of "hyperlink" and "bibliography" - ie, a list of links to electronic documents. Comparable to discography and bibliography, but not cartography.

We have been online since May 2000, and aim to be the best place to find and share science-related content of all kinds.

Share the love!
