MIT engineers make converting CO2 into useful products more practical

Glad they're finally making ice cream sandwiches out of it.

Could do with more caramel drizzle, though.

I was wondering about total cost in energy. In the sense that wind and solar basically convert a barrel of oil into X times a barrel of oil of energy. They are looking to make it economically feasible which should likely mean its ends up being efficient enough:

"Currently, ethylene sells for about $1,000 per ton, so the goal is to be able to meet or beat that price. The electrochemical process that converts CO2 into ethylene involves a water-based solution and a catalyst material, which come into contact along with an electric current in a device called a gas diffusion electrode."

People really gotta stop taking MIT articles as meaningful.
