Small Wonder Last Energy wants to make nuclear huge by making it tiny.

BRET KUGELMASS, THE 36-year-old founder and CEO of the nuclear startup Last Energy, is used to skeptics. "If your five closest friends have been misinforming you [about nuclear power], I can't blame you," he says. A slight grin hints at what he'd like to tell them: that nuclear power is far less deadly than our typical sources of energy; that it's still the only large-scale source of electricity and high-temperature heat that doesn't emit carbon; that its detractors often misunderstand it.

But Kugelmass isn't trying to convince skeptics. He wants to prove them wrong. In four years, he's gone from hosting a podcast about the nuclear industry to starting a nuclear company to, in recent months, inking nuclear power deals in Europe worth roughly $25.6 billion. Kugelmasswho has a master's in mechanical engineering from Stanford and became interested in nuclear after selling his aerial imaging company in 2017-now counts eight customers across three countries, for a total of 51 potential microreactors. He intends to have his first one running as early as 2026. "In one week [in March], he says, "we sold more nuclear power plant contracts than any company in all of history."

THE NEW RULES OF BUSINESS TRAVEL

In the era of hybrid teams, everyone is a road warrior-not just sales teams and C-suite execs. It's part of why business travel spending is expected to finally reach, and perhaps surpass, pre-pandemic levels by the end of the year, according to Deloitte. But, as with everything, work trips are not what they were in 2019. From airlines to banks, companies are finding new ways to make business travel easier-and even a little fun.
