A Silicon Valley startup is proposing to turn carbon dioxide emissions from coal and gas power plants into cement that can be used for everyday construction.
Critics are unsure whether Caldera, the startup, can make it a financially-feasible process.
From ASLA's blog: "Some scientists raise doubts the firm can pull it off, arguing that the idea has been explored for more than 15 years. There have been earlier failures, largely due to the costs involved. Beyond the costs of the actual process, infrastructure costs associated with scaling this up (and dealing with potentially massive amounts of that toxic acid) also need to be addressed."
