By burning CO2 do you mean with a naked flame like a fire? or could it be done like a electric heater? [?]

I think they meant "Why would you use energy to split CO2 (to carbon and oxygen) just so that you can burn it (the carbon) for energy?"
CO2 doesn't burn (OK, it would in a room full of magnesium vapour or some such).

Actually CO2 and water is in an equlibrium with H2CO3 - this is a part of an important system known as the carbonic acid system. One could, in theory, bubble atmospheric air through a column with water and thereby dissolving both the CO2 as aquatic CO2 and as carbonic acid. However, this obviously requires energy (as everything else).
