Good morning, Whitewater
In the City of Whitewater, the Whitewater University Tech Park Board meets at 1 PM.
At Lakeview School, the pennies for patients drive continues today.
On this day in American history, in 1879, Thomas Edison invented the incandescent light bulb:
Here the inventor gave a practical illustration of his invention. He was standing just under an ordinary gas chandelier in which two of his lamps were burning. He took one of the lamps out, and it appeared simply as a glass globe. He placed it back in the burner, and immediately a brilliant horse-shoe of golden light illuminated the globe. Mr. Edison then, by turning a screw in the lamp, brought the light down to a spark, turned it off completely, as gas can be turned off, and turned it on again to a brilliant incandescence by a twist of his fingers. He certainly demonstrated that in his own laboratory at Menlo Park, the electric light is as obedient to his will as the gas light is to the general public. The light from each lamp is of about the power of an ordinary gas-jet, but Mr. Edison claims that by increasing the electricity, he can raise the power to 15 gas-jets.
Eighty-four lights are burning night and day in the laboratory, and they are all supplied with electricity by an 80-horse-power engine, which is stationed in the basement of one of the buildings. This engine, in addition to feeding these lamps, furnishes the motive power for all the machines in the laboratory, and at night feeds the electric lights which have already been erected in Menlo Park, in anticipation of the proposed grand illumination. The wires which are to convey the electricity to the lamps for the grand display are to be above ground, so that all spectators can see and investigate them. They will lead directly from the lamps to the generator in the laboratory, and any person can trace them from point to point.
