Amazingly, Project Vanguard, the first satellite powered by solar, launched in 1958. It’s the longest orbiting man-made satellite and is still orbiting the Earth! Once scientists figured out that solar was the best way to power satellites, manufacturers were able to gain a toe-hold, foreshadowing today’s modern solar industry. Vanguard I is tiny – it weighs about 3 pounds and is 6 inches in diameter.

The details about this invention Bell disclosed at a press conference the company held in April 1954 greatly boosted interest in solar energy. John Yellott, a mechanical engineer who probably knew more about twentieth century attempts to use the sun’s energy than anyone else in America, hailed the silicon solar cell as "the first really important breakthrough in solar energy technology." In fact, according to a 1955 Newsweek report, many foresaw the solar cell’s development as an eventual competitor to atomic power. Technical Progress Continues in the Lab Technical […]
