Rubber is a complex hydrocarbon. Fundamental in its composition is isoprene. The organic chemist can make isoprene from such common stuffs as turpentine, petroleum, starch, coal tar or acetylene. News of goldenrod as a likely rubber source gave the casual daily press opportunity to picture farmers sneezing as they harvested the autumn-gorgeous weed. But goldenrod pollen is one of the lesser causes of hayfever. Ragweed, more widespread, is the chief cause...
...Barjot would generate his power in Polar regions where water under the ice is 32° F. (freezing) or warmer and the air above 20° below zero or colder. He would pump sub-ice water into a surface tank partially filled with butane or some other hydrocarbon of low vaporization point. In the tank the ice water would freeze and release it? comparative heat; the heat would volatilize the butane; the gaseous butane would run a low-pressure turbine. To condense the butane to liquid, after it had rotated the turbine, he would pass it through brine made from...
...water is actually most mysterious, should be studied, said Dean James Kennell of New York University. He reminded his audience that in a world where the active constituent of the atmosphere was hydrogen instead of oxygen, fires would be extinguished, not by throwing on water, but by some hydrocarbon such as gasoline...
...Paris National Automobile Exposition setting forth that it would henceforth manufacture this conveyance, the economy of which arose from its burning fuel, vaporized charcoal or raw wood. The wood is piled by the driver's seat, where he feeds it into a stove, which manufactures hydrocarbon gases which are then yalved into the motor in the ordinary way. An 80% reduction in fuel cost for light trucks was claimed. The truck could carry fagots enough for a 60-mile run without stopping; could refuel with anything driftwood, barrel staves, roots, cigar boxes...
