Nano Liquid Batteries

John Katsoudas [ TEDxIIT ] We all know that burning gasoline for transportation contributes significantly to an oncoming global calamity – climate change. We also know that switching to electric vehicles – or EVs – can improve the situation. I bet all of you, like me, care about the environment and most of you, like me, don’t own an electric vehicle.

Dame Helen MacArthur [ TED Vancouver ] When you’re a child, anything and everything is possible. The challenge, so often, is hanging on to that as we grow up. And as a four-year-old, I had the opportunity to sail for the first time. I will never forget the excitement as we closed the coast. I will never forget the feeling of adventure as

Graphene

Graphene

Shou-En Zhu [ TEDxDelft ] Nano materials and nanostructures exist everywhere in our natural world. Take a look at the wing of a dragonfly. If we zoom in 100,000 times and look at the transparent membrane, we can see the nanostructures which are invisible to the naked eye. Graphene is transparent. This is a molecular model of graphene. To make it visible, it

BILL MOYERS: So if we now have representative government in name only, and are governed instead by corporations and their lobbyists, what’s to be done? Tim Dechristopher wrestled with that reality and decided what he would do. As a result, he spent almost two years in prison.

This perfect storm is mounting a grim reality, increasingly grim reality, and we are facing that reality with the full belief that we can solve our problems with technology, and that’s very understandable. Now, this perfect storm that we are facing is the result of our

Better Biofuels

Better Biofuels

Jonathan Trent [ TED Edinburgh ] Some years ago, I set out to try to understand if there was a possibility to develop biofuels on a scale that would actually compete with fossil fuels but not compete with agriculture for water, fertilizer or land. So here’s what I came up with. Imagine that we build an enclosure where we put it just underwater,

Climate Change is Simple

Climate Change is Simple

David Roberts [TEDx TheEverGreenStateCollege ] This talk started out of a Twitter conversation. I haven’t decided whether to be embarrassed about that or not. But I was on Twitter one day and a relatively prominent left of centre pundit, piped up and said “You know, climate change seems like a really big deal, why are so few people talking about it? Why have
