This week on the show, we're sharing the debut of Positive Charge, a new GeekWire podcast from reporter Lisa Stiffler and producer Laura Scott about the innovations that could help save the planet. 

In this episode, they dig into the high-stakes race to harness the power of the sun and make fusion energy real, visiting two Seattle-area startups chasing this dream, and asking whether limitless clean power is finally within reach.

Also out this week: their debut episode on the "forever chemicals" in our water and the companies figuring out how to destroy them. Follow Positive Charge wherever you get your podcasts, or at geekwire.com/positivecharge.

Positive Charge is presented with support from Amazon Sustainability.
