After expanding through the nozzle, the air's temperature would drop greatly (due to the Joule-Thomson effect).
[10] In 1905, the company acquired Hampson's three patents on the liquefaction and separation of atmospheric gases.
[12] In 1900–1901, Hampson also conducted adult education courses; specifically, a series of lectures at the University College in London.
From these lectures came two books: Radium Explained (1905) provided a lay audience with an account of recent developments in research on radioactivity, while Paradoxes of Nature and of Science (1906) presented scientific curiosities that were contrary to common experience; e.g., how ice could be used as a source of heat.
[17] Hampson regarded credit—broadly interpreted as debt or borrowing in any form—as responsible for many of an economy's ills.
All sales would be in cash; debts would not be legally recognised; factories would be run as a cooperative of their workers.
