i found a schematic of a DC voltage doubler and my big question is, what will this due to battery life?

reason this could be a big deal is because we use fans in our helmets to help keep us cool, and most use a 9V batt. well if we can still use a 9V batt. yet get the fan to turn faster, it would be great.
