Comments (53)Wayne, here's the headline...Crystal power Palmtop Nuclear Fusion Device Invented By Michael Schirber LiveScience Staff Writer posted: 27 April 2005 01:00 pm ET The nuclear reaction that powers the Sun has been reproduced in a pocket-sized device, scientists announced today. Researchers have for years tried to harness nuclear fusion to power the world. But its cousin, nuclear fission -- the breaking apart of atoms -- is the only method so far commercially viable. The latest invention is not in the same league as efforts to build complex commercial reactors. The new device creates a relatively small number of reactions, and requires more energy to operate than it produces. The Real Deal (AP) - Previous claims of tabletop fusion have been met with skepticism and even derision by physicists. In one of the most notable cases, Dr. B. Stanley Pons of the University of Utah and Martin Fleischmann of Southampton University in England shocked the world in 1989 when they announced that they had achieved so-called cold fusion at room temperature. Their work was discredited after repeated attempts to reproduce it failed. Fusion experts noted that the new UCLA experiment is credible because, unlike the 1989 work, it did not violate basic principles of physics. "This doesn't have any controversy in it because they're using a tried and true method,'' said David Ruzic, professor of nuclear and plasma engineering at the University of Illinois at Urbana-Champaign. "There's no mystery in terms of the physics.'' -- Associated Press But the configuration is so small and simple that its creators think it may inspire unforeseen applications. "I certainly find it interesting that you can heat a cubic centimeter crystal in your hand, then plunge it in cold water and it will cause nuclear fusion," Seth Putterman from the University of California Los Angeles told LiveScience. Putterman's lay description greatly oversimplifies how the compact apparatus works. Specifically, Putterman and collaborators heat a pyroelectric crystal, lithium tantalite, from minus 30 degrees Fahrenheit to plus 45 in a matter of minutes. This generates an electrical charge -- 100,000 volts -- across the tiny crystal, which is housed in a chamber filled with deuterium gas, a heavy form of hydrogen. The high voltage is focused onto a needle-thin tip, which strips electrons from nearby deuterium nuclei and then accelerates them at a solid target containing deuterium. When two deuterium nuclei collide together at high speed, they fuse to form helium. The Sun also fuses atoms in thermonuclear reactions that create light and heat. The byproduct of the newly discovered lab reaction is a particle called the neutron. The scientists detect about 1,000 neutrons per second. Because neutrons are so penetrating, Putterman said that a hand-held neutron source might one-day be used to do geologic surveys or to look into cargo containers for nuclear devices. "Current neutron generators are extremely cumbersome," Putterman said. "They are about as big as a dentists X-ray machine, so you canÂt carry them into the field." Pyroelectric crystals could also provide a beam of ions for use as a microthruster in a miniature spacecraft. The research is described in the April 28 issue of the journal Nature....See MoreO/T but..do you do 'Thanksgiving'...?
Comments (88)In my family, in the Pacific Northwest of the United States the Thanksgiving meal always included: A big plate of crudites with onion dip. a crystal platter with black olives, enough for every child to slide a big black olive over each of her fingers. a big roast Turkey, when Grandma was alive it would be a 24 pound bird. with stuffing made with toasted bread cubes, onions, celery and sage and other herbs and chicken broth. gravy made with giblets. Mashed white potatoes made with butter and cream. Sweet potato sliced and baked with lots of butter and with small marshmallows baked on top. Cranberry sauce. One puts this on the turkey. I saw a movie set in England where someone very kindly tried to reproduce a Thanksgiving meal for his American wife and he served raspberry jam with the turkey. a heartfelt sentiment which is more important than food. If I were in England and couldn't find cranberries I'd look for lingonbery jam, for they are a bit closer to cranberries in taste, though the berries are smaller. Brussels Sprouts Rolls or biscuits and butter. and for dessert pumpkin pie with whipped cream on top. Now that I've lived in California for 30 years I've seen many Thanksgivings that had all of the above foods but also had in addition to pumpkin pie, a very rich pie made of pecans. Most of , no- all of the African Americans I've known always have sweet potato pie in lieu of pumpkin pie and in my opinion it is a far superior pie. Nowadays we usually start with a big salad often a Caesar salad as it is simple and the rest of the food is so rich. I love Thanksgiving, it is such a heartwarming holiday with none of the commercial stress of Christmas when one is rushing around trying to find a parking space and then the right gift for every one. Although it takes a large effort to cook a large Thanksgiving meal. I often feel closer to God on Thanksgiving for God is Love, and love is a familiar feeling on that day along with gratitude. Most Thanksgivings I've been at have always had one or two persons who were invited at the last minute when someone found out they had no family locally to go to . I have been that person myself several times when new to an area. Thanks for asking, Lux....See MoreOT: Hurray! the snakes are back
Comments (7)I had a green tree snake who lived in my last garden. He was quite beautiful, and harmless to humans. Here, unfortunately, my daughter had a brown snake in her flat (downstairs). She was certain it was the deadly one, and as she has worked with a wildlife service, I'm sure she was right. They used to be very common in these parts, and in the past I have had a few encounters I'd rather not think about. They actually chase you! The other day, when I was digging out a giant marauding salvia, I saw a baby brown snake (didn't rear at me, so maybe not the deadly kind) and a giant ant with a bright green head - both at the same moment, and scurrying in opposite directions! There used to be snake skins everywhere on roads, but you never see one now. Instead we have an exploding population of bush turkeys, so I was quite happy to see the baby snake. I just hope he's not a deadly one! The builder's son caught a funnel web behind my garage a few days ago (also deadly). He took it to the local hospital so they could extract the venom, as they're short of the anti-venom at the moment. This is a prime spot for funnel webs, as there are a lot of sunny drystone walls in this garden, and I'm told that's their favourite hangout. Carol, when we came to Australia 50 years ago, all I'd heard about were sharks, snakes and spiders. My parents bought a house in Palm Beach, a northern suburb of Sydney, which in those days had a lot of native bush, including our 'garden'. There were loads of brown snakes and spiders, and sharks in the water! I got used to it, and was later amazed to learn that most other Australians were quite alarmed by them! I never saw a bush turkey in those days, but did see koalas and wallabies - sadly long gone. Trish...See MoreOT - possum penthouse in my roses
Comments (20)I don't think we have possums here, not sure though. Don't want them here, just started to grow some fruit trees. I know nothing about possums, but I have a couple possum fur lined rain coats. Possum fur is not pretty, but it's very warm in the wet snow/ ice rain. On the country property there is a huge hole next to the house. Is this a fox hole/raccoon hole? I hope it's not a possum hole. We can hunt/ trap here, might have to trap them and drop them off at a church......should I flood the hole and see what comes out? I'd love to have a fox in the yard....See MoreHalloBlondie (zone5a) Ontario, Canada
