HOW TO BRING A MOONSHOT DOWN TO EARTH

Want to turn a big idea into a real business? Here's an inside look at how Google's attention-grabbing "moonshot factory" does it-by thinking big, killing ideas quickly, reimagining problems, and every so often, producing a company like Dandelion that just might change everything.

Elaine Weir is retired, which means that-apart from the swimming lessons she teaches a few times a week-she has a lot of time on her hands. So in the summer of 2019, when she saw a Facebook ad for the geothermal energy company Dandelion, she called them up to investigate. "I had no intentions of buying this thing," she says, with a conspiratorial cackle. "But my daughter suffers from asthma, so I wanted to do my small part to reduce our footprint. We were considering an electric car, but then I saw this..."

She agreed to let a salesman come to her home, a 100-year-old Tudor in the New York City suburb of Scarsdale. "He explained this and that," she says. "But when he said I could get rid of the air conditioning, that's when my ears perked up." Like many homes, her HVAC system required a giant, noisy set of outdoor AC condenser units. "I said, 'You mean these don't have to be here?' They're right next to my screened-in porch, and I can hear them in the middle of the night, and they're just plain annoying."

This wasn't the only information that impressed Weir that day. She learned that geothermal energy is the most sustainable way to heat and cool a home-emitting about one-fifth of the annual carbon dioxide that a gas- or oil-fueled system does. Once installed, it's also the most cost-efficient method out there, chopping down the average energy bill by 65% or more. Considering that geothermal technology has been around since the 1940s, Weir wondered, how was this the first she was hearing of this?

That's exactly the question that Kathy Hannun, who founded Dandelion, began asking seven years ago-in a place far, far away from the tidy lawns of Scarsdale. Back then, Hannun was working at X, Google's "moonshot factory" in Mountain View, California.
