Beep... wrong again Travelwp, you get confused by the flimflam man Trump....[And Trump is not the Second Coming of Jesus, perhaps the Devil but not Jesus]

"By the end of 1887 Westinghouse had 68 alternating current power stations to Edison's 121 DC-based stations. " Edison fought hard to discredit the use of AC, even electrocuted an Elephant to prove it unsafe and to promote his DC. Nicolas Telsa invented AC motors and generators.

Semi correct about a Blackman and the lightbulb. However Edison did not invent the bulb, it was a slow evolution with many failures. Some actually attribute the light bulb to ancient times along with the DC batteries.

"Latimer who was black improved upon Edison's original design. Latimer created a light bulb with a more durable filament made of carbon. He sold the patent to the US Electric Co. in 1881, and a year later patented a process for efficiently manufacturing the carbon filament. He even wrote a book in 1890 on electric lighting, the first of its kind. " Edison Labs research lightbulb improvements but did not actually invent the bulb.

Latimer was an inventor known for working closely with Alexander Graham Bell, who invented the telephone (though some claim that invention is actually Latimer's)."

As I said, the light bulb evolved and was probably invented or observed many times going back to antiquity.
"In 1802, Humphry Davy invented the first electric light. He experimented with electricity and invented an electric battery. When he connected wires to his battery and a piece of carbon, the carbon glowed, producing light. His invention was known as the Electric Arc lamp. And while it produced light, it didn’t produce it for long and was much too bright for practical use."

Telsa [Elon Musk] did not invent the electric car did he, No they have come and gone, but probably here to stay.

Latimer beat Edison by 2 years, so Biden was not telling a Trumper.
Latimer received a patent on January 17, 1882 for the "Process of Manufacturing Carbons", an improved method for the production of lightbulb carbon filaments.

The Edison Electric Light Company in New York City hired Latimer in 1884, as a draftsman and an expert witness in patent litigation on electric lights. While at Edison, Latimer wrote the first book on electric lighting, Incandescent Electric Lighting (1890) and supervised the installation of public electric lights throughout New York, Philadelphia, Montreal, and London. When that company was combined in 1892 with the Thomson-Houston Electric Company to form General Electric, he continued to work in the legal department. In 1911, he became a patent consultant to law firms.

Electric lighting is a sorted history... Edison did not invent the light bulb, he had the money to dev**e a staff of technicians a long hard effort to make it commercial.

Biden was not making a Trump like lie. Biden pointing out that a black-man was one of the keys to modern incandescent lighting so much so that Edison hired him based on Latimer's patented work.
