Cornell University is currently working on a technology that will
capture carbon dioxide before it gets into the atmosphere. A group of scientists proposed making a call that would use aluminum as an anode and carbon dioxide paired with oxygen as a cathode. The reaction between the cathode and anode would create electricity while also making a oxalate byproduct.
The group reported that their electrochemical cell generated 13 ampere hours per gram of porous carbon (as the cathode) at a discharge potential of around 1.4 volts. The energy produced by the cell is comparable to that produced by the highest energy-density battery systems.
This technology could do great things, such as reducing the carbon footprint and increasing natural ways to make more electricity. These types of technologies are even attempted to be used in vehicles!

Things that can help save the environment and also give humans something tangable such as renewable energy are always a plus!
