Correction: At 00:13:11, Chris mentions “50 cycles per second” when referring to early electrical systems in Canada. The correct figure is 25 cycles per second. At the time, some parts of Canada—particularly in Ontario—operated on 25 Hz power before the country standardized to 60 Hz. While certain regions may have used 50 Hz at various points, it was not the primary standard in Ontario during that period.

What can space travel teach us about the future of energy? In this episode of On Energy, Chris Hadfield speaks with aerospace engineer Lauren Lyons,whose career spans NASA JPL, SpaceX, and Blue Origin. They discuss the technologies that are powering space exploration, including solar-powered satellites and water-propelled spacecraft. Together, they explore how innovations beyond Earth could help reshape our methods of energy storage, usage, and our overall perception of energy at home.
