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:
“In all her products, Nature only develops her simplest germs. One would say that it was no great stretch of invention to create birds. The hawk which now takes his flight over the top of the wood was at first, perchance, only a leaf which fluttered in its aisles. From rustling leaves she came in the course of ages to the loftier flight and clear carol of the bird.”
—Henry David Thoreau (1817–1862)
“We have much studied and much perfected, of late, the great civilized invention of the division of labour; only we give it a false name. It is not, truly speaking, the labour that is divided; but the men.”
—John Ruskin (1819–1900)
““Art” is an invention of aesthetics, which in turn is an invention of philosophers.... What we call art is a game.”
—Octavio Paz (b. 1914)
