Elon Musk is going to pay $100 million towards a prize to come up with the best carbon capture technology. (Or so he tweets. Details are scarce so far.)
The maverick tech CEO’s promise is not particularly notable for its generosity. With a net worth of over $200 billion, $100 million is 0.05% of Musk’s wealth.
But still, the richest person in the world’s tweet brings attention to an often-overlooked technology that has been around since the 1970s but has mostly been relegated to niche corners of the energy community.
