“Hydrogen is an odorless colorless gas which, given enough time, turns into people”

“As an anonymous wit is supposed to have put it: "Hydrogen is a light, odorless gas which, given enough time, changes into people.”

“…he was doing a breath hydrogen test. If you know the amount of hydrogen someone is exhaling orally, it's a simple matter to extrapolate the amount they're exhaling rectally. This is because a fixed percentage of hydrogen produced in the colon is absorbed into the blood and, and when it reaches the lungs, exhaled. The breath hydrogen test has given flatus researchers a simple, consistent measure of gas production that does not require the subject to fart into a balloon.”

“I was standing outside myself trying to stop those hangings with ghost fingers... I am a ghost wanting what every ghost wants-a body-after the Long Time moving through odorless alleys of space where no life is, only the colorless no smell of death...Nobody can breath and smell it through pink convolutions of gristle laced with crystal snot, time shit and black blood filters of flesh.”

“How wonderful to find in living creatures the same substance as those which make up minerals. Nevertheless they felt a sort of humiliation at the idea that their persons contained phosphorous like matches, albumen like white of egg, hydrogen gas like street lamps.”

“Natural gas is highly explosive, invisible, poisonous, and odorless. Yet we accept natural gas, even though it kills not two but 400 Americans a year, because it was introduced before we got crazy about risk. We accept coal, even though mining it is nasty and filthy and kills dozens of people every year. By contrast, we're terrified of nuclear energy. Chernobyl, the worst nuclear power disaster ever, killed only 30 people. Some say the radiation may eventually kill others, but even if that's true, natural gas kills more people every year.”
