Letter Re: Switchgrass for Ethanol Production
Dear Jim,
I just discovered SurvivalBlog.com in November 2007. I have bought two
of your books so far. We are working on our lists, in the meantime I am building
FIFO shelving
for the canned part of our provisions. We thank God for you, your great work,
and The Memsahib's support of this.
I'm not so sure this article will be a fit, but it is good news nevertheless.
From Scientific American: Grass Makes
Better Ethanol than Corn Does. The USDA and farmers took part in a five-year
study of switchgrass, native to North America. They found that switchgrass
ethanol can deliver around 540
percent
of the energy used to produce it, as opposed to corn ethanol which can only
yield around 124 percent. - BCW
JWR Replies: Switchgrass does seem more viable for ethanol
production than corn, because of it his high EROEI ratio.
I am hopeful that an ethanol production
and distribution
infrastructure will be assembled in the US in the next three or four years.
OBTW, I highly recommend that every SurvivalBlog reader own at least
one "Flex Fuel" vehicle that is E85 ethanol
compatible. Make that a high priority
the next time you buy a new car or truck. Even if there is not yet E85 available
in your area, plan ahead for when it will be. Someday, you may be glad that
you did.
