Climate expert Ari Matusiak spends his days working to rewire America's energy system, and he has an idea: instead of tech companies building new power plants for their AI data centers, they should invest in energy-efficient upgrades to your home. He lays out how this swap could lower your power bill, reduce the strain on the grid and help communities reclaim control over the thing tech companies need most — power. Hosted on Acast.

In seven years as a political prisoner in Venezuela, activist Leopoldo López kept asking one question: Who holds the keys to freedom?

Grammy-winning musician Jacob Collier has a name for the feeling that moves through a great piece of music: the wiggle. Watch him break down the idea into its three parts — melody, rhythm and harmony — with nothing but his own voice, a grand piano and Louis Armstrong’s “What a Wonderful World.” Turns out life, like music, was never made to run in straight lines.

After working for years in film, fashion and graphic design, visual artist Kelly A. Boesch found a new collaborator to work with: AI.

3D printing promised to reinvent how we make things, but it's mostly stuck producing prototypes with a high level of waste. Designer and TED Fellow Schendy Kernizan found a different way — by printing objects directly into a tub of gel. He explains how this technique eliminates the constraints of gravity, pushing the limits of how we can manufacture objects across medicine, fashion, space travel and more.Following his story, pulled from a short film he made for TED, Kernizan speaks with Lily James Olds, director of the TED Fellows program, on where this fascination with making things first came from. They talk about what kind of objects Kernizan’s is most excited to build, how he overcomes setbacks, and what keeps him motivated. Hosted on Acast. See acast.com/privacy for more information.

What does a war look like when you sit still long enough to draw it? Reportage artist and TED Fellow George Butler sketches the people that the news passes by: a 99-year-old survivor of the Holodomor famine in Ukraine, a man gathering books blasted into a rose garden, an architect whose home was hit by a Russian missile. Urging us to slow down in the age of immediate news, Butler shows how a drawing reveals what a headline can't. Hosted on Acast. See acast.com/privacy for more information.
