Without running the numbers I would expect that you would burn more gas powering these than running a standard AC.

As an engineer I find it insulting that the poster seems to think GM has not thought of this and run the numbers. These sound like some clever kids but their quote about gas usage makes it very clear they have no idea how to calculate efficiency.

See Post 73, I'm sure that this was not the first time this was reviewed.
