Despite the fact that the world’s richest increased their wealth dramatically during the pandemic, there were still some moments of philanthropy that might even warm the heart, and hands, of Bernie Sanders himself.

The latest is from Elon Musk, the man battling it out with Jeff Bezos for world’s richest person, who has announced an initiative that targets innovation related to climate change.

In a competition announced late last week, Musk says he will give $100 million in prize money for the person or team who can develop the best carbon capture technology.
