Elon Musk wants your ideas about how to fight climate change — and he's willing to pay top dollar for them.
The billionaire SpaceX and Tesla chief and his Musk Foundation are funding a new Carbon Removal X Prize to the tune of $100 million — the richest incentive prize in history, according to X Prize officials.
The goal of the four-year contest is to nurture the development of technology that pulls enough heat-trapping carbon dioxide out of the air to take Earth off its disastrous warming trajectory.
"We want to make a truly meaningful impact. Carbon negativity, not neutrality," Musk said in a statement released by the X Prize Foundation. "This is not a theoretical competition; we want teams that will build real systems that can make a measurable impact and scale to a gigaton level. Whatever it takes. Time is of the essence."
Anybody around the world can enter the newly announced competition, the existence of which Musk teased last month. Full guidelines will be released on Earth Day (April 22) — the same day that registration begins — and the contest will run through Earth Day 2025, X Prize officials said.

The first big chunk of the $100 million will be doled out in October 2022 — $1 million each to the top 15 teams, as decided by a panel of judges. Around the same time, 25 scholarships worth $200,000 apiece will be awarded to student teams in the competition, X Prize officials said.
The overall winner of the competition will get the grand prize of $50 million, and second and third place will net $20 million and $10 million, respectively.
"The goal of this competition is to inspire entrepreneurs and engineers to build the carbon dioxide removal solutions, many of which have only been discussed and debated," X Prize founder and executive chairman Peter Diamandis said in the same statement.
"We want to see them built, tested and validated," he added. "We hope this X Prize will activate the public and private sectors to get involved in the same way that the $10 million Ansari X Prize brought about the commercial spaceflight industry."
The Ansari X Prize, which offered $10 million to the first private group that could fly a crewed vehicle to space twice within a two-week span, was won in October 2004 by the team behind SpaceShipOne. Shortly thereafter, Richard Branson licensed SpaceShipOne's technology and built his space tourism company, Virgin Galactic, around it. (Virgin Galactic's six-passenger suborbital spaceliner is known as SpaceShipTwo.)
