Is it costly to switch my gas Hummer over to cow burps?

I was using drip from Texas gas wells but it's harder to steal what with the Boarder patrol chasing the Mexicans. I heard Nancy (give us a grin) Polosi say that we need alternative fuels and wondered if all that hot air in the Congress could be used to heat Washington DC..I am committed to Green for sure, that's why my Hummer is green baby.|||Thanks for the good laugh.Love the part about the Boarder patrol chasing the Mexicans.Great sense of humor.You get a star for great question.Best of luck.
