Military Plans Tests in Search for an Alternative to Oil-Based Fuel - New York Times

Military Plans Tests in Search for an Alternative to Oil-Based Fuel - New York Times:

"WASHINGTON, May 13 — When an F-16 lights up its afterburners, it consumes nearly 28 gallons of fuel per minute. No wonder, then, that of all the fuel the United States government uses each year, the Air Force accounts for more than half. The Air Force may not be in any danger of suffering inconveniences from scarce or expensive fuel, but it has begun looking for a way to power its jets on something besides conventional fuel.

In a series of tests — first on engines mounted on blocks and then with B-52's in flight — the Air Force will try to prove that the American military can fly its aircraft by blending traditional crude oil-based jet fuel with a synthetic liquid made first from natural gas, and, eventually, from coal, which is plentiful and cheaper.

While the military has been a leader in adopting some technologies — light but strong metals, radar-evading stealth designs and fire-retardant flight suits, for example — any effort to hit a miles-per-gallon fuel efficiency rating has taken a back seat when the mission is to haul bombs farther and faster or push 70-ton tanks across a desert to topple an adversary. (The Abrams tank, for example, gets less than a mile per gallon under certain combat conditions.)

'Energy is a national security issue,' said Michael A. Aimone, the Air Force assistant deputy chief of staff for logistics.

The United States is unlikely ever to become fully independent of foreign oil, he said, but the intent of the Air Force project is 'to develop enough independence to have assured domestic supplies for aviation purposes.'

[...]

either Mr. Holmes nor the Air Force would provide cost estimates for the experimental fuel deal in advance of signing a final contract, expected in coming days.

Air Force officials have acknowledged, however, that the cost per gallon of the test fuel will be expensive.

Syntroleum can produce 42 gallons of synthetic fuel from 10,000 cubic feet of natural gas. The raw materials cost about $70.

If the military moves ahead with using the synthetic fuels, the Syntroleum technology could be used by factories elsewhere to produce the same 42 gallons of fuel from just $10 worth of coal, Mr. Holmes said.

"The United States is essentially the Saudi Arabia of coal," Mr. Holmes said. "It can be mined relatively inexpensively. We really believe that one of the things we can do to help our country's energy needs is to use the abundance of coal reserves."

Mr. Aimone said the large plants needed to produce nonconventional fuels did not exist and would have to be designed and built by the industry.

But he added: "We believe there are economic incentives as we invest in this, and invest with the industry at large, because there are vast coal reserves in this country. The economic pressures of rising oil prices can be moderated by the price of coal.""

Insulin Resistance- cause of ADD, diabetes, narcolepsy, etc etc

Insulin Resistance Insulin Resistance Have you been diagnosed with clinical depression? Heart disease? Type II, or adult, diabetes? Narcolepsy? Are you, or do you think you might be, an alcoholic? Do you gain weight around your middle in spite of faithfully dieting? Are you unable to lose weight? Does your child have ADHD? If you have any one of these symptoms, I wrote this article for you. Believe it or not, the same thing can cause all of the above symptoms. I am not a medical professional. I am not a nutritionist. The conclusions I have drawn from my own experience and observations are not rocket science. A diagnosis of clinical depression is as ordinary as the common cold today. Prescriptions for Prozac, Zoloft, Wellbutrin, etc., are written every day. Genuine clinical depression is a very serious condition caused by serotonin levels in the brain. I am not certain, however, that every diagnosis of depression is the real thing. My guess is that about 10 percent of the people taking

Could Narcolepsy be caused by gluten? :: Kitchen Table Hypothesis

Kitchen Table Hypothesis from www.zombieinstitute.net - Heidi's new site It's commonly known that a severe allergy to peanuts can cause death within minutes. What if there were an allergy that were delayed for hours and caused people to fall asleep instead? That is what I believe is happening in people with Narcolepsy. Celiac disease is an allergy to gliadin, a specific gluten protein found in grains such as wheat, barley and rye. In celiac disease the IgA antigliadin antibody is produced after ingestion of gluten. It attacks the gluten, but also mistakenly binds to and creates an immune reaction in the cells of the small intestine causing severe damage. There is another form of gluten intolerance, Dermatitis Herpetiformis, in which the IgA antigliadin bind to proteins in the skin, causing blisters, itching and pain. This can occur without any signs of intestinal damage. Non-celiac gluten sensitivity is a similar autoimmune reaction to gliadin, however it usually involves the

Blue-blocking Glasses To Improve Sleep And ADHD Symptoms Developed

Blue-blocking Glasses To Improve Sleep And ADHD Symptoms Developed Scientists at John Carroll University, working in its Lighting Innovations Institute, have developed an affordable accessory that appears to reduce the symptoms of ADHD. Their discovery also has also been shown to improve sleep patterns among people who have difficulty falling asleep. The John Carroll researchers have created glasses designed to block blue light, therefore altering a person's circadian rhythm, which leads to improvement in ADHD symptoms and sleep disorders. […] How the Glasses Work The individual puts on the glasses a couple of hours ahead of bedtime, advancing the circadian rhythm. The special glasses block the blue rays that cause a delay in the start of the flow of melatonin, the sleep hormone. Normally, melatonin flow doesn't begin until after the individual goes into darkness. Studies indicate that promoting the earlier release of melatonin results in a marked decline of ADHD symptoms.
