Alex Gendler: Building the world's largest (and most controversial) power plant

In 2018, a single power plant produced more energy than the world's largest coal-powered and gas-powered plants combined. China's Three Gorges Dam relies on running water, and is capable of producing more energy than any other power plant on Earth. So what allows Three Gorges to generate all this power? And how do hydroelectric plants work in th...

Hannah Bürckstümmer: A printable, flexible, organic solar cell

Unlike the solar cells you're used to seeing, organic photovoltaics are made of compounds that are dissolved in ink and can be printed and molded using simple techniques. The result is a low-weight, flexible, semi-transparent film that turns the energy of the sun into electricity. Hannah Bürckstümmer shows us how they're made -- and how they cou...

Taylor Wilson: Yup, I built a nuclear fusion reactor

Taylor Wilson believes nuclear fusion is a solution to our future energy needs, and that kids can change the world. And he knows something about both of those: When he was 14, he built a working fusion reactor in his parents' garage. Now 17, he takes the TED stage at short notice to tell (the short version of) his story.

James Gillies: Dark matter: The matter we can't see

The Greeks had a simple and elegant formula for the universe: just earth fire wind and water. Turns out there's more to it than that -- a lot more. Visible matter (and that goes beyond the four Greek elements) comprises only 4% of the universe. CERN scientist James Gillies tells us what accounts for the remaining 96% (dark matter and dark energy...
