Yesterday, Governor Bobby Jindal signed into law the Advanced Biofuel Industry Development Initiative, the most comprehensive and far-reaching state legislation in the nation enacted to develop a statewide advanced biofuel industry. Louisiana is the first state to enact alternative transportation fuel legislation that includes a variable blending pump pilot program and a hydrous ethanol pilot program.
The legislature found that the proper development of an advanced biofuel industry in Louisiana requires implementation of the following comprehensive “field-to-pump” strategy developed by Renergie, Inc.:
(1) Feedstock Other Than Corn
(a) derived solely from Louisiana harvested crops;
(b) capable of an annual yield of at least 600 gallons of ethanol per acre;
(c) requiring no more than one-half of the water required to grow corn;
(d) tolerant to high temperature and waterlogging;
(e) resistant to drought and saline-alkaline soils;
(f) capable of being grown in marginal soils, ranging from heavy clay to light sand;
(g) requiring no more than one-third of the nitrogen required to grow corn, thereby reducing the risk of
contamination of the waters of the state; and
(h) requiring no more than one-half of the energy necessary to convert corn into ethanol.
The legislature calls for a decentralized network of small biofuel manufacturing facilities each capable of producing 5 - 15 million gallons of biofuel per year. Variable blending pumps, directly installed and operated at local gas stations must offer the consumer a less expensive substitute for unleaded gasoline in the form of E10, E20, E30 and E85.
It is not entirely clear what crop this legislature was tailored for. Some believe it was tailored for sweet sorghum, considering that Renergie, Inc. was involved in developing the language. Sugarcane certainly should meet most if not all of the criteria listed above. Both are more energy efficient than corn, and neither has the same food-vs-fuel stigma that corn has.

U. S. Sugar Corp going out of business

Clewiston, Florida (where U.S. Sugar Corp is headquartered) may have to re-think its title, “America's Sweetest Town."

Tribute to my brother, Burton Tew Jr.
Burton has lived a most fascinating life, and is widely respected for his breadth of knowledge. He has been invited to speak at an array of forums on an incredibly wide range of topics. By training, he is a chemical engineer, but he can hold his own on topics that reach far beyond the realm of his formal training. It helps that he was born with a photographic memory. Burton has a great sense of humor, and the jokes in his memory bank that he can draw on is truly amazing. My personal favorite, is Rindercella, which he can still do on call, and every bit as funny as Archie Campbell's version. He and his sweetheart, Louise, raised six children, Leah, Patricia, Cindy, Bart (deceased), David, and Ronald. They presently have a pretty sizeable group of grandchildren, and are now at the age where great-grandchildren are part of their lives. Burton served on a mission in England (1948-50) and later with Louise as a missionary couple in San Diego (1992-93). Dad lived to age 78, so Burton has now surpassed him. God willing, he will have a few more birthdays yet to come.

Tew Family Crest
A long time ago, back when I was in college, I got the genealogy bug for a while. One of the projects I tackled was to create a Tew family crest based on a written description in a book about family crests, not based on any picture, per se. I thought I had long since lost the picture I had created, but it resurfaced the other day, so I scanned it.
Speaking of family names, I found a website that actually shows where each surname is most concentrated within in the United States. In the case of the name, Tew, the intermountain west and the southeast are where it is most concentrated. The states that light up the most are Utah, Alabama, and North Carolina.

Flex-fuel vehicles...what say you?
As a matter of course, at 7:00 pm, I find myself switching between O'Reilly's Factor (Fox News) and Olbermann's Countdown (MSNBC). While I'm not in full agreement with the positions of either of these polar opposites, occasionally I get sucked in to issues I have some passion for. Such has been the case with Bill O'Reilly over the past four days, with his Talking Points focusing on our need to reduce our dependence on OPEC Oil, controlled by Mideastern Oil Barons. I agree with him that these people who really don't like us very much, yet they are benefiting enormously from our consumption of their oil at current oil prices. Bill's answer in part is to mandate flex-fuel vehicles, and follow the lead of Brazil in becoming more oil independent through greater usage of home grown ethanol. Bill has been to Brazil several times and I am very happy that he aggressively challenges those who have jumped on the latest bandwagon to pooh pooh ethanol for various reasons.
From my perspective, ethanol has gotten a bad rap, because our ethanol is derived from corn, which is a lot harder to justify socially and energetically than ethanol from crops like sugarcane that have a much better energy balance, and less impact on world food supply.
Could we produce ethanol profitably from sugarcane in the U.S. at present oil prices? Right now, the sugarcane farmer is barely breaking even at the 20 cents a pound he is getting for the sugar he is producing. So, the simple answer would seem to be that if the farmer were getting more than 20 cents a pound for sugar converted to ethanol, and if the infrastructure were already in place, he would be better off producing ethanol. It takes roughly 12 lbs of sugar to produce one gallon of ethanol, and on an equivalent volume basis, ethanol will only take you about 70% as far down the road as gasoline. Therefore 12 lbs sugar x 20 cents/lb = $2.40/gallon or $3.40/gas-equivalent gallon. How much cheaper it would be to produce ethanol directly from sugarcane juice than from fully processed raw sugar? The Brazilians should be able to answer this question. Apparently, they can produce ethanol at around 85 cents/gallon and I believe that they sell sugar at the world market price which is currently around 10 cents/lb. Could molasses and lower strikes of sugar be routed toward ethanol production, while only the highest strike of sugar (A-strike) be used toward the production of traditional sugar products? Is Brazil's claimed 8:1 energy output:input ratio valid? How much different is our ratio?
