"Re-industrializing and rearming Europe is a project that's going to take at least 10 years. We need all the capital we can get flowing into the ecosystem."

Bill Gates–backed nuclear start-up TerraPower just got cleared to start building its first power plant

“Globally, only about 25 significant reactors have been built using sodium cooling, and most of them weren’t used to generate power; the US hasn’t built one since the 1960s and hasn’t operated one since the 1990s. This is a radical design, and the company could still face many hurdles before getting approval to operate it.”

"Despite current limitations, our research could serve as a foundation for the design and fabrication of multi-dielectric photonic crystal sails. It may provide a pathway to experimentally validated, scalable, lightweight devices for laser-driven propulsion, enabling future interplanetary exploration with minimal onboard mass," said Dimitar Dimitrov, an assistant professor at Tuskegee University.
