Leila Conners interviews John Todd about the inspiration behind the water machine and how it works. John Todd was inspired by the interaction of the multitudes of life in the waters around Cape Cod, where he grew up. From that inspiration he invented the water machine, or the ecomachine...also known as a living machine. What the water machine does is use sunlight and a system of vats that contain plants, algae, bacteria, fish, snails...the multitudes...to cleanse polluted water. So in one end runs the polluted water, and out the other flows water free of metals, pollutants and is of the quality of drinking water.

Diane Young Kim of USC Wrigley Institute on Catalina Island in California walks us through their work on growing kelp on "kelp elevators" thus increasing their biomass, and then transforming it into a more carbon neutral jet fuel.

Charlie Blair, co-founder and managing director of Gravitricity walks us through the ingenious solution to energy grid storage based on weights and gravity. Gravitricity will become part of the world's toolbox of solutions when transitioning to 100% renewable energy.

Leila Conners discusses direct air capture (DAC) with Climeworks' Director and Founder, Christoph Gebald. Direct air capture pulls carbon out of the sky and turns it into feedstock for a multitude of applications including carbon negative fuels. DAC can also pull carbon out of the sky and permanently sequester it in the ground and Climeworks is doing that in Iceland.
