Derek Muller, creator of the science-themed YouTube channel Veritasium, won a $10,000 bet with UCLA physics professor Alexander Kusenko, who claimed that Muller’s wind-driven land yacht couldn’t travel faster than the wind without any additional power sources. After recruiting science stars Neil deGrasse Tyson and Bill Nye to help settle the debate, the professor eventually conceded that it was in fact possible. Insider reports: Created by Rick Cavallaro, a former aerospace engineer, Blackbird is unique because it can move directly downwind faster than the wind itself for a sustained period. Any sailor worth their salt can tell you that a boat can travel faster than the wind by cutting zigzag patterns; that’s called tacking. But the idea that a vehicle can beat the breeze traveling straight downwind, no tacking involved, is controversial. “I knew this was a counterintuitive problem. To be perfectly honest with you, when I went out to pilot the craft, I didn’t understand how it worked,” Muller told Insider.
Blackbird is so counterintuitive, in fact, that less than a week after Muller released his video (below), Alexander Kusenko, a professor of physics at UCLA, emailed to inform him that it had to be wrong. A vehicle like that would break the laws of physics, Kusenko said. “I said, ‘Look, if you don’t believe this, let’s put some money on this,'” Muller said. He suggested a wager of $10,000, never imagining Kusenko would take it. But Kusenko agreed, and in the weeks that followed, they exchanged data and argued about Blackbird. They even brought in several of science’s biggest names, including Bill Nye and Neil deGrasse Tyson, to help decide who was right. In the end, Muller emerged victorious.
