Daniel Schnitzer: Inventing is the easy part. Marketing takes work

Solar-powered LED lightbulbs could transform the lives of rural Haitians, but as Daniel Schnitzer found, they don't simply sell themselves. At TEDxPittsburgh, he shows how smart health and energy products for the developing world are useless unless the market works too.

Holly Morris: Why stay in Chernobyl? Because it's home.

Chernobyl was the site of the world's worst nuclear accident and, for the past 27 years, the area around the plant has been known as the Exclusion Zone. And yet, a community of about 200 people live there -- almost all of them elderly women. These proud grandmas defied orders to relocate because their connection to their homeland and to their co...

Henry Richardson : What does the world's largest machine do?

In 1967, Homer Loutzenheuser flipped a switch and connected the power grids of the United States, forming one interconnected machine. Today, the US power grid is the world's largest machine, containing more than 7,300 electricity-generating plants. So how exactly do these power plants work?

Wolfgang Kessling: How to air-condition outdoor spaces

During the hot summer months, watching an outdoor sports match or concert can be tantamount to baking uncomfortably in the sun -- but it doesn't have to be. At the TEDxSummit in Doha, physicist Wolfgang Kessling reveals sustainable design innovations that cool us from above and below, and even collects solar energy for later use.

Al Gore: How to make radical climate action the new normal

A net-zero future is possible, but first we need to flip a mental switch to truly understand that we can stop the climate crisis if we try, says Nobel laureate Al Gore.

How can a super-thin 3-inch disk levitate something 70,000 times its own weight? In a riveting demonstration, Boaz Almog shows how a phenomenon known as quantum locking allows a superconductor disk to float over a magnetic rail -- completely frictionlessly and with zero energy loss. Experiment: Prof. Guy Deutscher, Mishael Azoulay, Boaz Almog, o...

John C. Moore and Eric Berlow: Dead stuff: The secret ingredient in our food chain

When you picture the lowest levels of the food chain, you might imagine herbivores happily munching on lush, living green plants. But this idyllic image leaves out a huge (and slightly less appetizing) source of nourishment: dead stuff. John C. Moore details the "brown food chain," explaining how such unlikely delicacies as pond scum and animal ...

TED-Ed: The world's biggest battery looks nothing like a battery

As of 2020, the world's biggest lithium-ion battery is hooked up to the Southern California power grid and can provide enough power for about 250,000 homes.

Renée Hlozek: The death of the universe

The shape, contents and future of the universe are all intricately related. We know that it's mostly flat; we know that it's made up of baryonic matter (like stars and planets), but mostly dark matter and dark energy; and we know that it's expanding constantly, so that all stars will eventually burn out into a cold nothingness. Renée Hlozek expa...

Eleftheria Pissadaki: A mathematical model for predicting Parkinson's

What if we looked at Parkinson's as an neurological electrical problem? Brain researcher Eleftheria Pissadaki and her team study dopamine neurons, the neurons that selectively die during Parkinson's. They discovered that the bigger a neuron is, the more vulnerable it becomes because it simply requires more energy. This new insight is reframing t...
