The first all-electric school bus in the state of California pausing outside the California capitol building in Sacramento. Since 2015, the Canadian manufacturer Lion Bus offers a full size school bus, eLion, with a body made out of composites. It is a regular production version that is built and shipped in volume since early 2016, with around ...
Belgian engineer Zenobe Gramme who developed the DC generator accidentally discovered that a DC generator also works as a DC motor during an exhibit in Vienna. 1876: Paper capacitor manufacturing started. 1876: Russian engineer Pavel Yablochkov invented the electric carbon arc lamp. 1876: Scottish inventor Alexander Graham Bell patented the ...
Each school day in 2015, nearly 484,000 school buses transported 26.9 million children to and from school and school-related activities; over half of the United States K–12 student population is transported by school bus.
Moore School of Electrical Engineering. The Moore School of Electrical Engineering at the University of Pennsylvania came into existence as a result of an endowment from Alfred Fitler Moore on June 4, 1923. It was granted to Penn's School of Electrical Engineering, located in the Towne Building. The first dean of the Moore School was Harold Pender.
It was built by Moore School of Electrical Engineering at the University of Pennsylvania. [1] [2]: 626–628 Along with ORDVAC, it was a successor to the ENIAC. Unlike ENIAC, it was binary rather than decimal, and was designed to be a stored-program computer.

This became the classic means of measuring the charge-to-mass ratio of the electron. Later in 1899 he measured the charge of the electron to be of 6.8 × 10 −10 esu. [33] Thomson believed that the corpuscles emerged from the atoms of the trace gas inside his cathode-ray tubes. He thus concluded that atoms were divisible, and that the ...
