On November 17th, 2023 the average global temperature was temporarily 2 degrees Celsius warmer than pre-industrialization, an event with ominous climate implications. To slow global climate change, we need to find ways to supercharge natural carbon removal processes like ocean alkalization, and do it in a way that is good for the planet. 

That’s exactly what this month’s Watt It Takes Guest, Ben Tarbell, Co-Founder and CEO of Ebb Carbon, is doing.

The team at Ebb is approaching carbon removal in a way that is both novel and as ancient as the ocean itself; integrating with existing facilities that process seawater, they use electrochemistry to remove acidity, and return the alkaline seawater to the ocean where it can then absorb more carbon.

Ebb has raised $23M, has a team of 40, and is deploying their carbon removal system. I spoke to Ben about his journey, from his childhood spent obsessed with building and engineering, to his career in solar, to prototyping the Ebb System in a bathroom-less empty warehouse, to opening Ebb’s first site and starting to meaningfully remove carbon via the ocean.

Cardiac Cowboys

Cardiac Cowboys

The heart was always off-limits to surgeons. Cutting into it spelled instant death for the patient. That is, until a ragtag group of doctors scattered across the Midwest and Texas decided to throw out the rule book. Working in makeshift laboratories and home garages, using medical devices made from scavenged machine parts and beer tubes, these men and women invented the field of open heart surgery. Odds are, someone you know is alive because of them. So why has history left them behind? Presented by Chris Pine, CARDIAC COWBOYS tells the gripping true story behind the birth of heart surgery, and the young, Greatest Generation doctors who made it happen. For years, they competed and feuded, racing to be the first, the best, and the most prolific. Some appeared on the cover of Time Magazine, operated on kings and advised presidents. Others ended up disgraced, penniless, and convicted of felonies. Together, they ignited a revolution in medicine, and changed the world.
