Modern Uses
Dynamos still have some uses in low power applications, particularly where low voltage DC is required, since an alternator with a semiconductor rectifier can be inefficient in these applications. 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 modern mind is in complete disarray. Knowledge has streched itself to the point where neither the world nor our intelligence can find any foot-hold. It is a fact that we are suffering from nihilism.”
—Albert Camus (1913–1960)
“Through a series of gradual power losses, the modern parent is in danger of losing sight of her own child, as well as her own vision and style. It’s a very big price to pay emotionally. Too bad it’s often accompanied by an equally huge price financially.”
—Sonia Taitz (20th century)
