Hand cranked dynamos are used in clockwork radios, hand powered flashlights, mobile phone rechargers, and other human powered equipment to recharge batteries.

Famous quotes containing the word modern:

    The poverty of our century is unlike that of any other. It is not, as poverty was before, the result of natural scarcity, but of a set of priorities imposed upon the rest of the world by the rich. Consequently, the modern poor are not pitied ... but written off as trash. The twentieth-century consumer economy has produced the first culture for which a beggar is a reminder of nothing.
    John Berger (b. 1926)

    The susceptibility of the average modern to pictorial suggestion enables advertising to exploit his lessened power of judgment.
    Johan Huizinga (1872–1945)
