World leaders looked at a Formula 1 car made from recycled plastic and a microwave-sized device that can generate hydrogen fuel Tuesday as they looked to promote innovation to slow climate change at the U.N. summit in Glasgow.

Speaking at the summit, President Joe Biden said that “our current technology alone won’t get us where we need to be.” He added, “we need to invest in breakthroughs.”
