Can a Simple Brick Be the Next Great Battery? | John O'Donnell | TED

The world relies on manufacturing, and manufacturing relies on heat - a massive contributor to global carbon emissions, responsible for a quarter of the world's fossil fuel use. Energy entrepreneur John O'Donnell has figured out a better, cleaner way to generate the heat we need to make the stuff we want. Learn how his team turned simple bricks and iron wire into a powerful, unconventional "heat battery" that could deliver industrial heat at scale without the emissions - and why he thinks electrified industrial heat is the next trillion-dollar industry.
Countdown is TED's global initiative to accelerate solutions to the climate crisis. The goal: to build a better future by cutting greenhouse gas emissions in half by 2030, in the race to a zero-carbon world. Get involved at countdown.ted....
