Alexander knew the significance gas lighting could have on a civilization as it was capable of transforming the dark, economically useless night into a productive time almost equal to the day, and almost doubling it's industrial output.

He also knew that none of the challenges of collecting the gas by heating coal through pyrolysis was nowhere substantial enough to be unassailable.
