Elon Musk will give away $100 million in XPrize Carbon Removal contest

There's a total of $100 million up for grabs from Tesla CEO Elon Musk for anyone who can combat global warming by capturing carbon dioxide from the atmosphere. 

Musk and his XPrize Carbon Removal contest are looking for workable solutions for reducing the planet's CO2 emissions at scale in a "durable and sustainable way." The contest started on Earth Day and will last four years, ending on Earth Day 2025, or April 22, 2025. Everyone from high school students to startups, as well as universities, companies, individuals or community-based organizations, are welcome to apply. "We're looking for pragmatic solutions," Musk said during a live talk on Periscope this week. "It doesn't need to be perfect, but it's gotta be something that — fundamentally — if we scaled it up, would it work? That's it."
