Looking for cars that run on CO2, producing oxygen as result. Wink

That's not how physics works. Breaking up CO2 into carbon and oxygen requires energy, it is impossible to produce energy this way.

But CO2/Methane reaction releases water, and only about half as efficient as gasoline/oxygen Cheesy

Given the relatively cheap production and renewability of methane, might be a good idea.

Why would you want CO2 to react with Methane, instead of burning the methane? That seems like a terrible way to get carbonmonoxide.
CO2 + CH4 → 2 H2 + 2 CO

+1
And I don't see why methane would be anyless effective than other hydrocarbons
CH4 + 3O2 => 4H2O + CO2
