Invention
Nikola Tesla filed a patent in 1896 for a vacuum capacitor. The original use was to enhance the quality of the electrical components for handling "currents of high frequency and potential". These components were necessary for the DC impulse research which Tesla was studying. Commercial products have been available since 1942.

Famous quotes containing the word invention:
“Heredity is a strong factor, even in architecture. Necessity first mothered invention. Now invention has little ones of her own, and they look just like grandma.”
—E.B. (Elwyn Brooks)
“His mind was great and powerful, without being of the very first order; his penetration strong, though not so acute as that of a Newton, Bacon, or Locke; and as far as he saw, no judgment was ever sounder. It was slow in operation, being little aided by invention or imagination, but sure in conclusion.”
—Thomas Jefferson (1743–1826)
“The rage for road building is beneficent for America, where vast distance is so main a consideration in our domestic politics and trade, inasmuch as the great political promise of the invention is to hold the Union staunch, whose days already seem numbered by the mere inconvenience of transporting representatives, judges and officers across such tedious distances of land and water.”
—Ralph Waldo Emerson (1803–1882)
