00:00But not just for NASA. Other institutions and companies are also researching this technology,
00:07including DARPA, General Electric, the US Navy, several universities, the Japanese space agency
00:14JAXA and some Chinese institutes, just to name a few. Why is this so revolutionary? RDE's can
00:21theoretically be up to 25% more efficient than conventional rocket engines. That means more
00:29thrust from less fuel. For spaceflight, that's like a free upgrade from economy to business class.
00:36That means you can carry 25% more payload with the same amount of fuel. Or put differently,
00:43you can make your rocket 25% smaller. These engines can be built smaller and lighter.
00:49In space travel, where every gram counts, that is worth its weight in gold.
