Solving Solar’s Biggest Problem Feb 13, 2025

Show notes

We need better, cheaper ways to store solar and wind energy when it’s dark out and the wind isn’t blowing.
One option: Compressing air in underground caverns when energy is abundant, then blowing it back out to create energy when you need it. It’s an old idea, but it has some fundamental problems.
Curtis VanWalleghem, the co-founder and CEO of Hydrostor, thinks his company has solved those problems with a new approach. If he’s right, his firm will help fix the biggest bottleneck slowing down the adoption of solar and wind power.

Teaching AI to Build Stuff in the Physical World Jan 30, 2025

Show notes

AI works well in the virtual world. That’s partly because the internet provides so much data to train AI models. But there’s no analogous data set for the physical world – and as a result, AI doesn’t work as well there… yet.

Edward Mehr is the co-founder and CEO of Machina Labs. Edward's problem is this: How can you use AI to turn robots from dumb, inflexible machines into skilled, versatile craftsmen?

What Claude Shannon Figured Out Jan 16, 2025

Show notes

Claude Shannon is a major figure in the history of technology. Known as the father of information theory, Shannon spent decades at Bell Labs and MIT. But what exactly did Claude Shannon figure out, and why is it so important?
To answer that question, Jacob talked with David Tse, a professor of electrical engineering at Stanford who studied under one of Shannon’s students, and who teaches Shannon to his own students today. David used Shannon's work to make a breakthrough in wireless communication that underpins every phone call we make today.

Turning Solar Energy Into Fuel (The Solar Era, Part 3) Dec 02, 2024

Show notes

Solar power and batteries are becoming cheap and ubiquitous. Great. But there are problems batteries can’t solve – like fueling ships and planes. One way to solve those problems: Use solar power to create hydrogen, and turn that hydrogen into fuel.
Today’s guest is Raffi Garabedian, the co-founder and CEO of Electric Hydrogen. Raffi’s problem is this: How do you turn solar and wind energy into clean hydrogen that’s cheap enough to compete with fossil fuel?
This is the last of three episodes we’re doing about the solar-power revolution. Listen to the previous episodes on your podcast player or at our website: https://www.pushkin.fm/podcasts/whats-your-problem
