I've never been a casino gambler and never one to throw $10 bills out the car window to see how far they fly. Both ventures are about as productive, about the same as burning incandescent bulbs, and make it a $20 spot for summer light if you have a/c - pay more to light your path and pay again to make the journey cool. Always amazes me why anyone wants to throw money away every time a light switch is flipped on for an incandescent bulb - and to throw that money to BIG UTILITY on top of it. An equally great idea is to invent a gasoline engine for a car that only gets 8 mpg! Wouldn't the demand be great? That's about the same as inventing an incandescent bulb today and expecting anyone to buy them - 1/4 the efficiency of a CFL. 8 mpg vs 32 mpg. It's a no-brainer.
