What the fracking flip?

Sounds like a real phrase some mormons might use instead of swearing, but "fracking" is an actual term to mean getting natural gas from shale.  The Environmental Protection Agency is concerned that fracking will pollute water and air.  The reason fracking is becoming so popular is because it brings natural gas prices down and this natural gas can be an alternative to coal for electric power generators.  Despite protests, fracking is skyrocketing and the US natural gas reserve has as well.  To read more, see http://www.csmonitor.com/

How does this relate to RVing?  Well, does anyone know of an RV that can take natural gas for fuel instead of diesel?  Ever heard of the Avanti Ecostar?  Apparently, it's the first natural gas RV that came out onto the market about a year ago (August 29- September 8, 2009).  For more information on that, check out: http://www.ngvglobal.com/  Also, if you know of any other RVs at this point that are natural gas powered, let me know.  I'd LOVE to hear about it! 

How long do you think it will be until other RVs are natural gas powered?  Maybe the Class A will never be natural gas powered (look at my "glossary of terms" post in June for a refresher as to what a Class A RV is if needed), but very possibly (more) Class B or C will be natural gas powered in the future.  Do you think it's possible, probable, both or neither?

There are a couple of books you might be interested in on Amazon for more information on fracking and the fracking controversy: Collateral Damage: A Chronicle of Lives devastated by Gas and Oil Development and the Valient Grassroots Fight to Effect Political and Legislative Change ... Gas and Oil Industry in the United States & EPA tackles fracking.(MINING)(Environmental Protection Agency): An article from: Environmental Health Perspectives

Good fracking luck!
