A visit to X: The tech moonshot factory is working on climate change

As we look ahead to 2020 and think about tackling giant problems, climate change is high on the list. So, we wanted to re-air an interview with the leader of a company that thrives on tackling giant problems. X, Formerly Google X, is the division of Alphabet devoted to moonshots. Its climate-related graduates include Dandelion, which harnesses heat from geothermal energy, and Malta, which uses salt to store excess energy produced from solar and wind farms.
