Set it up in Venezuela. Electricity isn't necessarily cheap, but gas is almost nothing. You'd need a pretty large generator, but I think I paid $0.25 USD for a 10 gallon tank of gas in 2010, and it's cheaper now than it was then.
I'm getting investors in on this. I have a hard enough time relating the concept to them, and taking their capital to Venezuela would call for an incredibly sly pitch on my part. And keep in mind most Americans don't like Venezuela (save, of course, when they pull into a Valero to fill up). But it is definitely interesting and I'd like to see the math on that. I'm not sure how fast an industrial generator would go through 1 gallon of gas.
