Nice thought Carleton but it wont work. Just think of the chaos which could occur in places like Seattle. 20 or 30 people sentenced to fry on one of the three clear sunny days they have a year! (ya just gotta love using a "smiley face" emoticon in THIS conversation!)

The good people of Seattle would have to contract out the executions and that would lead to use of fossil fuel. Hmmm, maybe a line of chained prisoners walking to a more southern state?

We could use ethanol I suppose, just call it a "Flexecution".
