Colonizing Mars: The Simple Device That Could Turn CO2 Into Vital Fuel

Researchers have developed thermoelectric generators that, even under modest temperature differences, can power a CO₂ conversion process.

This technology, tested in lab settings, could be particularly useful in geothermal installations on Earth and potentially support life on Mars by utilizing the planet’s abundant CO₂.

Readily available thermoelectric generators operating under modest temperature differences can power CO₂ conversion, according to a proof-of-concept study by chemists at the University of British Columbia (UBC).

The findings open up the intriguing possibility that the temperature differentials encountered in an array of environments—from a typical geothermal installation on Earth to the cold, desolate surface of Mars—could power the conversion of CO₂ into a range of useful fuels and chemicals.
