"Bedrock, a two-year-old, Brooklyn-based startup, aims to make the process up to 10 times faster with its electric, autonomous underwater vehicles (AUV) that can navigate along the ocean floor in waters up to 300 meters deep. Bedrock is still in the early stages of testing this tech—it has only built one AUV so far—but it raised $8 million in a seed round last March and is hiring 'aggressively' to grow the current team of ~20 full-time employees, its CEO and co-founder, Anthony DiMare told us."

"But, with the current slate of nuclear plants under construction, there is at least some hope that nuclear is regaining acceptance, and can make a growing contribution toward arresting the growth of global carbon emissions."

Maddie Stone writes in The Verge on innovative ways that wind turbines are being repurposed. “That makes it just the second ‘blade bridge’ in the world.

"In December 2021, RMI’s startup accelerator, Third Derivative (D3), announced First Gigaton Captured, a four-year partnership with the Jeremy and Hannelore Grantham Environmental Trust to find, fund, and scale the most promising carbon removal startups. First Gigaton Captured will focus on specific areas for innovation in direct air capture technology, and qualified startups are encouraged to apply when applications open in March."

"Operating the power plants of the future based on fusion would produce no greenhouse gases and only very small amounts of short-lived radioactive waste."
