In this episode of Hardware to Save a Planet, host Dylan Garrett talks with Luke Iseman, founder of Make Sunsets, about tackling climate change through stratospheric aerosol injection. They explore the challenges of scaling hardware solutions, the urgency of immediate climate action, and the ethical debates around geoengineering. Luke shares his vision for using sulfur dioxide balloons to cool the planet, sparking a thought-provoking discussion on innovation and sustainability.

Luke Iseman founded Make Sunsets, a pioneering company dedicated to combating climate change through stratospheric aerosol injection. With a background as a hardware startup veteran and former director of hardware at Y Combinator, Luke has a wealth of experience in launching innovative hardware solutions across various sectors, including precision agriculture and affordable housing. His current venture aims to cool the Earth by releasing sulfur dioxide into the stratosphere, a process inspired by natural volcanic eruptions that have historically led to global cooling.

Luke's work is particularly relevant in the context of the need for urgent climate action and he seeks to respond rapidly to the escalating effects of climate change. Notably, he has successfully engaged over 700 customers, generating significant interest in his cooling credits, which offer a tangible way for individuals and organizations to contribute to climate solutions.
