About WIRED MAGAZINE: ISSUE 15.07 - How Slick It Is! Fill 'Er Up With Cooking Oil, Not Crude Oil

John Voelcker

No need to battle other eco-warriors for a spot on the Prius waiting list. If you want to drive a green machine, just troll craigslist for an old diesel car or truck. Any diesel engine can run on vegetable oil — either used (fryer fat) or fresh out of the 5-gallon jug (Costco, baby!). The conversion process can be embarrassingly simple. Rudolf Diesel encouraged the use of veggie oil in his original engine, and later models require minimal tinkering to guzzle Wesson instead of Exxon: a booster pump here, a high-flow filter there. Los Angeles based Lovecraft, the cottage-industry leader, has modified more than 1,000 vehicles and sells DIY kits for the mechanically inclined. The company will convert almost any diesel rig, but Mercedes, Volkswagen, and Ford are optimum choices. It's the perfect excuse to fry every meal. Do it for the environment.

Mercedes-Benz 300SD, 1981 85

Blue book Value $3,200 (average)
Conversion cost $700

The 300SD can run on vegetable oil without modification — until the fuel filter chokes on the more viscous liquid (the conversion kit includes a bigger, high-flow heated filter). But Lovecraft prefers the 300SD because its fuel tank sits high up, behind the rear seat: Gravity helps the oil flow without stressing the pump.


Volkswagen Jetta TDI, 1996 2006

Blue book value $3,800 - 8,950
Conversion cost $950
Various Veedubs used this turbodiesel motor, but it's most common in the Jetta. The conversion requires changing the electrical relays, replacing the glow plugs, and various other mods. But you get startling results: It performs better on vegetable oil than on regular diesel, though Lovecraft hasn't studied it enough to say why.


Ford F250 Diesel, 1995 2000

Blue book value $6,325 - 12,900
Conversion cost $950
Need a green pickup truck or van? Ford's ubiquitous 7.3-liter Powerstroke V8 has been known to last 500,000 miles and makes for a straightforward conversion. Lovecraft installs a heat exchanger to thin the grease so it combusts easily. And although the company usually swaps in custom glow plugs, if the stock plugs are working well, the engine starts fine on veggie oil.

Making Water From Thin Air

A company that developed technology capable of creating water out of thin air nearly anywhere in the world is now under contract to nourish U.S. soldiers serving in Iraq.

The water-harvesting technology was originally the brainchild of the Pentagon's Defense Advanced Research Projects Agency, which sought ways to ensure sustainable water supplies for U.S. combat troops deployed in arid regions like Iraq.

"The program focused on creating water from the atmosphere using low-energy systems that could reduce the overall logistics burden for deployed forces and provide potable water within the reach of the war fighter any place, any time," said Darpa spokeswoman Jan Walker.

To achieve this end, Darpa gave millions to research companies like LexCarb and Sciperio to create a contraption that could capture water in the Mesopotamian desert.

But it was another company, Aqua Sciences, that developed a product on its own and was first to put a product on the market that can operate in harsh climates.

"People have been trying to figure out how to do this for years, and we just came out of left field in response to Darpa," said Abe Sher, chief executive officer of Aqua Sciences. "The atmosphere is a river full of water, even in the desert. It won't work absolutely everywhere, but it works virtually everywhere."

Sher said he is "not at liberty" to disclose details of the government contracts, except that Aqua Sciences won two highly competitive bids with "some very sophisticated companies."

He also declined to comment on how the technology actually works.

"This is our secret sauce," Sher said. "Like Kentucky Fried Chicken, it tastes good, but we won't tell you what's in it."

He did, however, provide a hint: Think of rice used in saltshakers that acts as a magnet to extract water and keeps salt from clumping.

"We figured out how to tap it in a very unique and proprietary way," Sher said. "We figured out how to mimic nature, using natural salt to extract water and act as a natural decontamination.

"Think of the Dead Sea, where nothing grows around it because the salt dehydrates everything. It's kind of like that."

The 20-foot machine can churn out 600 gallons of water a day without using or producing toxic materials and byproducts. The machine was displayed on Capitol Hill last week where a half-dozen lawmakers and some staffers stopped by for a drink.

"It was very interesting to see the technology in action and learn about its possible implementation in natural disasters," said Rep. E. Clay Shaw Jr., a Republican from Florida whose hurricane-prone district includes Fort Lauderdale.

"It was delicious," Shaw said.

Jason Rowe, chief of staff to Rep. Tom Feeney, another Florida Republican, called the technology "pretty impressive."

"I was pretty blown away by the things it's able to do," Rowe said. "The fact that this technology is not tied to humidity like others are makes it an attractive alternative for military bases in the Mideast where humidity is not really an option.

"It seems like it's a cheaper alternative to trucking in bottled water, which has a shelf life," said Rowe, who described himself as a fiscal hawk.

Once deployed, the machines could reduce the cost of logistical support for supplying water to the troops in Iraq by billions of dollars, said Stuart Roy, spokesman of the DCI Group, Aqua Sciences' public affairs firm.

The cost to transport water by C-17 cargo planes, then truck it to the troops, runs $30 a gallon. The cost, including the machines from Aqua Sciences, will be reduced to 30 cents a gallon, Roy said.

Several systems on the market can create water through condensation, but the process requires a high level of humidity.

Aqua Sciences' machines only require 14 percent humidity, Roy said. "That's why this technology is superior and why they are getting the contracts."

Deathbed Confession Says Aliens Were at Roswell

xnuandax writes ;

"The army's explanation of weather balloons in the Roswell, New Mexico incident 60 years ago has been dealt a serious public relations blow. Late Army Lt. Walter Haut had signed a sealed affidavit prior to his death last year asserting that he had witnessed the wreckage of an egg-shaped craft and its extraterrestrial crew while working at the Roswell Army Air Field. An article at News.com.au reviews how Haut had worked as public relations officer for the Roswell base and was involved in the original weather balloon explanation of events at the time. This recent evidence would seem to confirm speculation that egg-shaped saucers are notoriously difficult to fly safely at low altitude." Source : Slashdot

Tangible Display Makes 3D Touchable

moon_monkey writes;

"Researchers in Japan have developed a display that makes 3D objects solid enough to grasp. The system, created by engineers at Japan's NTT, combines a 3D display with a haptic glove, making 3D items that look real but also feel solid to touch. Two cameras are used to image an object, to make the 3D image. A computer also uses this to render a solid representation. It could be used to inspect products remotely, or even to shake hands with someone on the other side of the world, the researchers say."

to rate sample images based on
how much it turns you on (or off).

---

One frequent theme in my e-mail inbox is "Where can I find good porn?"

If you've written to me, you know that I do try to reply to everyone except the most obvious trolls, even if it takes me a while to get to you. And I answer questions as best I can.

But this is a difficult question to answer. What does "good porn" mean to you, and how much are you willing to pay for it?

Recently, one reader expressed frustration that on the occasions I do link to or recommend adult content, it's not free. "I have followed many of the links I find in your columns, but they all seem to wind up at commercial sites that want my credit card," he writes. "I don't think you want to be a shill for commercial porn, but sometimes I get that feeling."

Of course I am not a shill. I am selective, in that I rarely write about things I don't like unless I just can't keep my trap shut, but to be honest, I don't pay much attention to whether the adult sites I link to are free.

I have neither the time nor the patience to click through gallery after gallery of boring pictures or to sit through a series of low quality 1-minute clips. I'm 35, no longer on a Top Ramen budget, and frankly, what I like was hard to find even in the glory days of free porn.

If I can have a reasonable guarantee that the content I'm buying is what I want it to be, I'm willing to pay for it.

Yet I sympathize with the desire for recommendations from someone you know. Porn, like sex, can get awfully personal. If you feel an affinity for my taste, it's natural to ask me what I like and where to find it.

Daniel Gluck, executive director of the Museum of Sex (NSFW) in New York, sympathizes with the situation as well -- so much so, he's trying to do something about it.

The result is the fledgling MoSex Index (NSFW), an attempt to combine the best of social content with "taste networking."

"Our social content engine is similar to Digg or Reddit, where members can post content and others can rate it. Based on content thresholds, who is doing the rating, karma and reputation, links make it to the homepage," Daniel says.

"But -- and I think this is an extremely important aspect of the project -- we've also incorporated a collaborative filtering element. On other sites, you rate or (don't) rate; we have a degree of rating based on a 7-point Likert scale that adds weight to your like or dislike. We take that intelligence and form 'taste profiles,' which combine to form 'taste networks.' When people in your taste network find content they like, that content gets recommended to you."

The MoSex Index is barely launched, and like any community-based project, its usefulness will depend on the quality and quantity of its membership. So far, the user group has been small, with 70 testers posting links and adding ratings.

"Even with the small group, we're seeing semi-accurate predictions, on a broad scale, of what users might like," Daniel says. "Just with our museum staff, we can see who is most similar to whom. That's one of the aspects that's been most interesting to the staff, seeing whose tastes match."

When you create your MoSex Index user profile, you answer several questions about your sexual orientation, gender and preferences, then rate sexual situations based on how strongly they turn you on or off. Finally, you rate several pictures on how they affect you -- does the pin-up art thrill you or bore you? What about a Hustler photo of an all-female three-way? Or two 1950s male bodybuilders posing nude in a natural landscape?

July 2, 1928: America's First TV Station Goes on the Air

1928: W3XK, the first American TV station, begins broadcasting from suburban Washington, D.C.

The station was an outgrowth of the work done by Charles Francis Jenkins in devising a way to transmit pictures over the airwaves, a process he called "radiovision." He sold several thousand receiving sets, mostly to hobbyists, and, after receiving permission to start an experimental TV transmitting station, aired programming five nights a week until shutting down in 1932.

Jenkins essentially brought the wrong technology to the field: His receiving sets relied on a 48-line image projected onto a 6-inch-square mirror to create the picture, rather than using electronics, the technology that determined the future of television.

An interesting aside: Jenkins was also the first to air a television commercial. He was fined by the government for doing so, a practice that was discontinued, unfortunately, as the medium matured.

Chinese Company OKs Deal on Sudan Oil

AP Writer

China's No. 1 oil company, CNPC, and Indonesia's PT Pertamina have agreed to co-develop a Sudanese offshore oil block, ignoring international efforts to isolate Sudan over the crisis in its Darfur region, a report said Monday.

The agreement, signed Thursday in Sudan's capital, Khartoum, calls for a six-year exploration phase and shared future oil production under a 20-year concession, the CNPC-backed China Petroleum Daily reported. LINK
