While we are on fermented foods it is good to mention raw dairy products and whole food eating.
Raw dairy has resurfaced mostly in organic food stores. People seeking the highest ingredients for their diets. Raw dairy has not been pastuized meaning it contains all the beneficial bacteria and the enzymes / nutients that help the body digest and assimilate the foods. Raw milk is available in California and proves to reinstate the claim for milk's incredibly beneficial properties to health. All the enzymes still intact the body can assimilate far more nutrients. Not only can it assimilate the nutrients but it does not have to deal with processing the unassimiable wastes regular milk leaves in our colons. The weight of the undigested substaces pasturized milk leaves in our bodies seems to outweigh it's digestable benefits. Raw cheese is the same story.
Whole food eating is nature's answer to supplementation. Many supplements we take are simply wisked away through our kidneys leaving the body when you take a leak. The same vitamin C you get in a carrot however has calalysts and enzymes coming along with it, helping the body to use the substance. There have been many cases where science has isolated an active ingredient in say a healing herb only to find the active ingredient doesn't have the same beneficial effect when used on its own. Many folks I know say it is better to get your vitamins and minerals from the food you eat not through supplementation. The above mentioned phenomenon being the cause for argument. All in all it is another case of man vs. nature. Nature often times providing the perfect and complex combination of factors which often times produce better results.

www.nytimes.com/2006/01/31/science/31nuke.html"How to Listen for the Sound of Plutonium" by David E. Sanger and William J. Broad 1/31/06 NYTIMES This article explores the latest ideas for detecting the unsanctioned production of weapons grade plutonium by "rogue" nations, specifically Iran. The ideas range from detecting the electrical signature of centrifuges in the power grid to robotic butterflies to sniff the air unnoticed. The best way to catch clandestine nuclear developers may be through the detection of uranium hexafluoride gas. Another way is to search for a type of antimatter: antineutrinos. Last year Iran complained to the U.N. about the crash of two unmanned U.S. aircraft that were allegedly used to search for nuclear weapons facilities.

“Corn Power Put to the Test” by Mathew L. Wald 2/7/6 New York Times www.nytimes.com/2006/02/07/science/07fuel.htmlThis article points out the idea that Ethanol requires a substantial amount of energy to produce, and examines some ideas to make corn power a more sustainable energy source. The article explains four methods for “greening” of ethanol production. The first way is to use the residual corn with starch removed as cattle feed. The Cattle manure can be used for methane production, “Cow Power”. The second way to save energy of production is to bring cows closer to the production facility. Usually the leftover corn has to be dried to ship to where livestock eat it. By having the cows nearby this step can be skipped, saving energy. The third technique to increase efficiency is being accomplished by burning CO and H produced from the left over corn plant instead of natural gas. By using “partial oxidation” steam is used to break up the plant’s carbohydrates into these two flammable gasses. The fourth idea is to turn manure directly into gas. These ideas are steps to take us away from fossil fuels. I made a separate chart to help me understand the Electron Configuration listing the elements and configurations vertically down a sheet of paper. I recommend for people having trouble with this information to try rewriting it in a different way. Just writing can help understanding in a different way than reading does. Please help. My student question for the week involves Question 3 in the homework. There were some questions like this in the last chapter also. It seems to me that there can be more than one answer, or the answer depends on your point of view. I expect science to be more black and white, right or wrong. Can someone help me with this concept in general and Question 3 specifically?

I didn't realize these are questions. Are they? I tried going to the link but you need to register / or have credentials to see the story. If I was asked to create fuel from natural gas there is a couple of things that come to mind.
1) Easiest thing is just burning the raw manure, and using that to power a steam generator. 2) Collect all of the manure, and put it in a pile. Then take a huge hood / vacuum and suck up all of the methanol / hydrogen gas. Take this mixture and use a centerfuge to seperate the gases.
I don't understand all this about how corn fuel takes more energy to produce then its worth. I dont see that. I can goto the store and buy a gallon of corn alchohol for less then a gallon of gasoline. So how is it more worthwhile to use gasoline? I would use corn alchohol to power my tractors and other farm equipment. It will never get more efficient unless we start using it.

What is question 3?
I thought they Debunked that whole fuel from a cows ass back in the late 90's.
Plus what really kills me about the whole US fuel consumption arguement is that everyone looks a transportation needs. SUVs this and price at the pump that. The lion share of fossil fuel consumption in this nation has nothing to due with automibles. most raw materials go into utilty production, producing electricty, purify water, heating skyscrappers. So if you really want to save the world, yes cut down on aimless driving, but mostly turn off the lights when your not in a room and put on a freakin' sweater. As long as your house stays above 45-50 degrees your pipes won't freeze, after all it is winter and we do live in the midlatitudes.
And don't forget it took more raw ore to make your laptop than it did to make my 96' chevy Blazer.

Check out this NASA articale I found from 2003 Inside the Electrostatic Levitator at NASA's Marshall Space Flight Center in Huntsville, Ala., a metal sample is suspended by electromagnetic energy. At the start of the experiment, the red glow of the pointing laser is reflected on the metal sphere, where the heating laser is aimed to melt the solid sample. As the sample melts, it glows red, then yellow, and white at its hottest. Then, the laser is turned off and the sample cools, changing from a liquid drop of molten metal alloy to a solid sphere. Data taken during this phase change helped Dr. Kenneth Kelton, a physicist at Washington University in St. Louis, Mo., validate a 50-year-old hypothesis that explains why liquid metals resist turning into solids.

It is an orb of metal be levitated in a relative 0g environment be super heated by laser, causing it to melt and the resolidify.

Here's one of the answer to your domestic energy problems. Ever since that article came out about how the Gulf Stream is slowing, the Brits have been scrambling to fix some huge holes in the global pollution issue. I'll see if I can't find that article on the Gulf Stream, as I remember it is a bit lacking in hard evidance but without that current, see ya later Northern Europe. UK 'should pursue' carbon capture Capturing carbon dioxide could be economic, the committee believes Capturing and storing carbon dioxide from power stations could help Britain meet its energy needs while curbing greenhouse gas emissions, MPs say. to check out the full article go to: news.bbc.co.uk/2/hi/science/nature/4695478.stmF.Y.I. the U.S. houses 26% of the globe's recoverable coal reserves. Hello increase in GNP. Other reserves: 23% Former Soviet Union 12% China 8% Australia 7% Germany 5% S. Africa 2% Poland U.S. Department of Energy

On a some what similar note, Sweden has released a plan to become oil-free by 2020. Allow me to reiterate for those who read fast, [glow=green,2,300]OIL FREE[/glow] No industrialized nation has even come close to announcing a goal of this magnitude. They also detail that they won’t have to produce a single new nuclear plant in order to meet their goals of oil free living. An interesting side note to this article is that these plans were released in late 2005 and though I could find numerous foreign and hippy media sources for this article. I couldn’t find it on any of the big US media groups. Those of you who know me know I am not big into conspiracy theories but really WTF.

There was something bothering me about those robotic Butterflies joe mentioned earlier, and it didn't hit me til right now. But a year ago it was discovered that Homeland Security had a pilot program implace that used trained bees to shiff out bombs and other undesireables in US airports. If i remember correctly it only takes a few weeks to train an entire colony of bees for security detail and they are more effective then dogs.

Attack of the killah bees,, we on tha swarm!
COW POWER, VT we have extensive methane reclamation transfer into electricity here. If you pay an extra 0.25$ on you electric bill they buy more cow power.
Also new grass clippings into pelets being used for heat and electric production up here.

A friend of mine does this show: Internationally recognized "spiritual peace-maker" Dr. John Davies will be my guest on the next radio/web broadcast of Sufism: The Heart of Islam on Monday, February 20th at 5:30 pm Pacific time. During the show, Dr. Davies will talk about his landmark study on the effects of group meditation on casualties and violence during the Lebanese Civil war. Dr. Davies found that by bringing groups of Muslims and Christians together to meditate on peace, the casualty rate would drop, overnight, from about 12 a day to under 3 per day. This profound effect vanished as soon as the meditation groups disbanded. His results were published in the Journal of Conflict Resolution in 1988 and he has been studying this powerful phenomenon with groups around the world ever since. Dr. Davies specializes in conflict management and transformation across ethnic, religious and national lines and has brought together conflicting parties in over 20 countries on six continents. He is currently working with Hindu and Muslim groups in India and Pakistan. The scientific rigor that he brings to his work, coupled with its radical implications for our world, are sure to impress and inspire you. I hope you can join us. The show airs live over the web at www.kwmr.org and in parts of the San Francisco Bay Area at 90.5 or 89.3 FM on the radio dial.
