Toronto Western Hospital is launching the largest wastewater heating system in the world.

Yup, the hospital will get 90% of its heating from heat exchangers that suck heat out of Toronto's sewer system and then upgrades the temperature with heat pumps to heat the hospital complex. It's just like geoexchange systems (geothermal) except the heat comes from the sewer instead of the Earth.

If this sounds crappy, consider the hospital will save $700,000 per year on utility costs.

We talk to Ed Rubenstein formerly of the University Health Network and now the VP of Business Development with Noventa Energy, the company that built the $43 million project.

Our full interview with Ed Whittingham on his new podcast "Scrubbing the Sky" involves going beyond energy transition to zero-emissions energy and also capturing carbon from the atmosphere and locking it up.In this episode, we take a deep dive into why some believe we need to go beyond energy transition and directly capture carbon from the atmosphere to avoid the most catastrophic impacts of climate change. Whittingham reveals where the idea for the podcast came from, what can be done to remove carbon from the atmosphere, and who is doing it.Surprise, surprise! One of the key figures in direct air capture of carbon dioxide is Dr. David Keith, a physicist and a co-host of the "Energy vs Climate" podcast along with Ed Whittingham and Dr. Sarah Hastings-Simon.

Ed Whittingham calls himself "a climate citizen at large." He's also the host of the Energy vs Climate podcast, the former executive director of the Pembina Institute and the host of a new podcast called "Scrubbing the Sky."

He says we will have to do more than transition our energy systems to zero-carbon sources to combat climate change.

To stave off the worst impacts of climate change he says we will need to remove carbon from the atmosphere by scrubbing the sky.

We barely scratch the surface of this story in our short radio feature, check out our full interview to learn more about the different ways of removing carbon and about the companies doing it already including Dr. David Keith, a physicist who founded Carbon Engineering. Oh, by the way Keith is also a co-host of Whittingham's other podcast entitled "Energy vs Climate."
