Biden promises trains will travel at thrice the speed `of light, or something.

“What we’re really doing is raising the bar on what we can imagine. Imagine a world where you and your family can travel coast to coast without a single tank of gas on a high-speed train close to as fast as you can go across the country in a plane,” Biden said at the White House.

He added: “I tell the kids, the young people who work for me, tell my kids when I go on college campuses: they’re going to see more change in the next 10 years than we’ve seen in the last 50 years. We’re going to talk about commercial aircraft flying at subsonic speeds — supersonic speeds. To be able, figuratively, if you may, if we decide to do it, traverse the world in about an hour, travel 21,000 miles an hour. So much is changing and we have got to lead it.”

The globe’s circumference is 24,901 miles. Biden’s proposed rate of air travel would be more than 15 times faster than the Concorde’s cruising speed.
