He founded Sunpower Inc., [35] which researches and develops FPSC systems for military, aerospace, industrial, and commercial applications. A FPSC cooler made by Sunpower was used by NASA to cool instrumentation in satellites. [36] The firm was sold by the Beale family in 2015 to become a unit of Ametek. [37]
A refrigerator designed to reach cryogenic temperatures (below 120 K, -153 °C, -243.4 °F) is often called a cryocooler.The term is most often used for smaller systems, typically table-top size, with input powers less than about 20 kW.
Swanson was born in Davenport, Iowa in 1945. [1] He graduated in 1969 with Bachelor of Engineering and Master of Engineering degrees from Ohio State University and, in 1975, received a Doctor of Philosophy in electrical engineering from Stanford University. [1] He then joined the university faculty at Stanford and began research in solar cell ...
SunPower Corporation is an American provider of photovoltaic solar energy generation systems and battery energy storage products, primarily for residential customers. The company, headquartered in San Jose, California, was founded in 1985 by Richard Swanson, an electrical engineering professor from Stanford University.
The first experimental machines were built in the 1990s, when (commercial) cryocoolers became available, capable of reaching a temperature lower than that of liquid helium and having sufficient cooling power (on the order of 1 Watt at 4.2 K). [6] Pulse tube coolers are commonly used cryocoolers in dry dilution refrigerators.
Pulse tube cryocoolers are used in niche industrial applications such as semiconductor fabrication and superconducting radio-frequency circuits. [1] They are also used in military applications such as for the cooling of infrared sensors. [2] In research, PTRs are often used as precoolers of dilution refrigerators.
Maxeon was spun off from SunPower in August 2020. Maxeon was the primary provider of solar panels for SunPower through March 2024. [ 2 ] Beyond the United States, Maxeon has sales operations in more than 100 countries and has the rights to use the SunPower brand in countries outside the United States.
The Science Center of Iowa is a science museum located in Des Moines, Iowa. The museum opened in 1970 in Greenwood-Ashworth Park and was called the Des Moines Center of Science and Industry. [1] It was renamed the Science Center of Iowa in 1985. [1] It moved to its current location in 2005. [1]
