00:07UK promise ISP values over 10,000 seconds, but they are still years or even decades away.
00:14Founded in 2011 by Richard Dinan, Palsar tested hybrid rockets with polyethylene and nitrous
00:22oxide in 2021, also known as laughing as, and in 2022 developed and tested a Hall effect thruster
00:31with an exhaust velocity of 20 kilometers per second. As of January 2024, the company is working
00:38on a so-called direct fusion drive or DFD for short, a conceptual fusion drive with low radioactivity
00:46that provides both thrust and electricity.
