6 FAQs about [Caltech solar power from space]
What is Caltech's space solar power project?
Formed in 2011, Caltech’s Space Solar Power Project was made possible from more than $100 million in donations from Donald Bren, chairman of the Irvine Co. and a Caltech trustee, and his wife, Brigitte.
What is Caltech's space solar power demonstrator?
Caltech’s Space Solar Power Demonstrator, launched in January, includes an array of different types of advanced solar panels to test which will work best for a space solar power station, as well as a test system designed to unfold into a 6-by-6-ft. structure that could be used to hold solar panels, alongside Hajimiri’s energy transfer system.
What is the goal of the Space Solar Power Project (SSPP)?
The Space Solar Power Project (SSPP) aims to harvest solar power in space and transmit it to the Earth's surface. Wireless power transfer was demonstrated on March 3 by MAPLE, one of three key technologies being tested by the Space Solar Power Demonstrator (SSPD-1), the first space-borne prototype from Caltech's Space Solar Power Project (SSPP).
How much did Caltech spend on a solar power station?
Caltech’s $100 Million Gambit A NASA artist's rendering from 1999 of a solar power station in orbit. Like many other space-based solar designs, it required many connected parts, which translates to considerable launch costs. In 1941 Isaac Asimov, the science fiction writer, published a short story called " Reason ."
Will Caltech launch a solar array in 2022 or 2023?
That's a lot of money, and, importantly, the work has been spread out over a decade. A team at Caltech is aiming for the first launch of a test array in late 2022 or 2023. "This is something that's pretty daring," says Ali Hajimiri, a professor of electrical engineering and a co-director of Caltech's Space Solar Power Project.
How did the Caltech effort start?
The Caltech effort to develop space solar power began after philanthropist Donald Bren learned about the potential for space-based solar energy manufacturing as a young man after reading an article in Popular Science magazine.
