Nothing on our planet could function without pooower! Even though energy is all around us, harnessing that energy and turning it into power is a massive challenge. Powering our day-to-day lives makes up almost half of fossil fuel emissions, which is causing climate change! Tai tries to find out if there's a better way to power the planet.

In this episode Tai talks to:

- Richard Randell, engineer and PhD candidate at Stanford's Mechanical Engineering program

- Daniel Ddiba, research associate at the Stockholm Environment Institute. He conducts research into how poop can be used as fuel for industries and other applications in African cities

- Jim Green, chief scientist at NASA, who tells Tai how NASA's planning on providing power for future colonies on Mars, 140 million kilometres away.
