How we can turn the cold of outer space into a renewable resource | Aaswath Raman

What if we could use the cold darkness of outer space to cool buildings on earth? In this mind-blowing talk, physicist Aaswath Raman details the technology he's developing to harness "night-sky cooling" -- a natural phenomenon where infrared light escapes earth and heads to space, carrying heat along with it -- which could dramatically reduce the energy used by our cooling systems (and the pollution they cause). Learn more about how this approach could lead us towards a future where we intelligently tap into the energy of the universe.

He details how “climate capitalism” — the strategic use of market forces and government policies to make polluting the planet cost more than advancing climate solutions — can flip the script and actually make sustainability profitable.

A bold plan to rewild the Earth — at massive scale | Kristine McDivitt Tompkins

A bold plan to rewild the Earth — at massive scale | Kristine McDivitt Tompkins

The first step to saving nature is the rewilding of our own minds, says conservationist and former Patagonia CEO Kristine McDivitt Tompkins. With an unwavering commitment to protecting ecosystems, she and her late husband Douglas Tompkins created vast conservation parks across South America that allowed ancient flora and fauna to flourish once again. Now, she's carrying that legacy and mission forward with a bold plan to connect parks across geographic boundaries, creating a system of continental-scale wildlife corridors — before it's too late.

Can dogs detect the next pandemic before it begins? | Glen J. Golden

What if animals like dogs, ferrets, mice and raccoons could help sniff out the next pandemic? Exploring the science of smell, neurobiologist Glen J. Golden delves into the development of a "mechanical nose" that could detect diseases by identifying specific odor profiles. Until that technology is fully developed, he explains how we can train humanity's furry allies to identify illnesses — and help stop the spread in its tracks. Hosted on Acast.
