Here’s a cool idea: Use hot rocks to fight global warming. Heirloom superheats limestone to extract its CO2 and stores the gas far undergroun­d. The treated mineral then acts like a wrung-out sponge, reabsorbin­g greenhouse gases from the air. “We give rocks superpower­s to scrub CO2 out of our atmosphere,” says McQueen, who earned a Ph.D. in chemical engineerin­g from the University of Pennsylvan­ia. McQueen and cofounder Shashank Samala have raised a $53 million round and signed carbon offset deals with tech giants Microsoft, Stripe and Shopify. Rana Abdelhamid, 29
