Millions of American households rely on oil for heat. Growing up in New Hampshire, Kathy Hannun was familiar with this decades-old and environmentally-taxing approach. As part of Google’s innovation lab, X, she began unearthing a solution — indeed from underground...

This week on How I Built This Lab, Kathy discusses how her company, Dandelion Energy, has made geothermal energy accessible for heating and cooling homes across the northeastern United States. Plus, Kathy explains why widespread adoption of geothermal heat pumps is important if we want to reach our climate goals.




This episode was produced by Sam Paulson and edited by Casey Herman, with music by Ramtin Arablouei. Our audio engineer was Katherine Silva.

When Madeline Haydon decided to turn her homemade, plant-based coffee creamer into a business, she didn’t fit the mold of a typical founder. She was a woman of color, pregnant with her second child, and had no experience in the food industry. At first, almost all of her sales were through Amazon, and she struggled to convince investors to take a risk on her. But over 10 years, she grew nutpods from a $30,000 Kickstarter campaign into a leading coffee creamer brand, now available in 15,000 stores across the US. 




This episode was produced by Alex Cheng with music by Ramtin Arablouei. It was edited by Neva Grant. Our audio engineers were Gilly Moon and Patrick Murray.

Every summer for the past seven decades, 50 high school seniors—one from every state—descend on Mobile, Alabama to take part in one of the country’s most lucrative scholarship competitions for teen girls. 




The Competition takes you behind the scenes of the Distinguished Young Women (DYW) program, and follows seven girls as they experience the highs and lows of competing for two weeks, away from home and under the most high-stress circumstances. Some girls enter for the money, some for prestige. All of them are used to being the best and the brightest. But only one will walk away with the top prize.




Host Shima Oliaee (Dolly Parton’s America, Pink Card) was Nevada’s contestant in 2001. More than 20 years later, she returns to Alabama as a judge. What can two weeks with 50 of the country’s most ambitious teens tell us about girlhood in America?

As co-founder of Twitter and founder of Blogger and Medium, Evan Williams literally helped change the conversation: he understood that real-time connectivity—being able to write a post and have people read it seconds later—was the future of engagement online. A Nebraska farm boy who dropped out of college, Ev ran into several business failures before starting Blogger, and—after it sold to Google—launching Twitter with Jack Dorsey and others. Ev also came to learn that he understood product better than people, a trait that would contribute to his eventual ouster as Twitter CEO. After that crushing blow, he returned to his first love by starting Medium, a blogging site for posts that are neither too short or too long.
