Oil prices are at an all time low, but that's not going to stay like that forever. One day, we'll run out of oil, and we're going to be in trouble. Which is why this machine could be something we desperately need. It makes oil by combining hydrogen and CO2.

Made by Sunfire, it uses the Fischer-Tropsch process, truning carbon monoxide and hydrogen into liquid hydrocarbons.

The only problem? It requires a lot of electricity to turn water into steam. Will this machine be mainstream?
