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 MoreNeed a new refrigerator, any recommendations on which one?
Comments (114)We purchased a Samsung French door refrigerator - Model RF24FSEDBSR/AA - in November 2014 (now about 2.75 years old), and have had, along with evidently countless others, problems with the ice maker, which quit working just after the one year warranty period was over ... soft ice cubes, water and crushed ice build-up in the chute, dripping water, and massive ice build-up in the back of the unit that evidently blocked the fan and eventually burned out the motor. The first appliance repair company called would not service a Samsung refrigerator (wonder why); the second came out three times ... went through all of the Samsung "service bulletins" in regard to this issue and eventually said they would not continue trying to fix it and to call Samsung (we paid for one service call with this company, the other two were gratis). Samsung "Support" set up an appointment with one of their locally contracted appliance repair companies - we paid for the service call and their assessment was that we needed a new fan/motor. On the next service call he brought and installed the new part. We paid for the part, something like $140. Shortly after the "repair", the unit again began to fail and we called again (after cleaning out the ice build-up several times). The part was guaranteed for three months, but we did not realize this and called again just after the three month period. The solution - again - to replace the fan/motor in the ice maker. We paid again for the part, and the company kindly did not charge us this time for the service call. Fast forward two months, and the ice maker unit is failing AGAIN - we've melted out the ice build-up two or three times in the last six or seven weeks. Over the last few days, a new issue - the "Twin Cooling" unit in the back of the refrigerator has failed - ice build up in the "Twin Cooling" unit, the fan died, and the refrigerator now keeps a temperature of around 50 degrees. The drawer and the freezer are still maintaining a safe temperature, so we are using those alone while we search for another refrigerator; given that we've paid upwards of $500 for repairs that did not work we are not willing to sink more money into repairs. I've read that they have since improved the ice maker, but have made no move to my knowledge to recall or replace defective models or parts. Needless to say, we are not seeking to replace this refrigerator, or any other appliance, with a Samsung model....See Moreconnecting parts of a pellet stove power backup system
Comments (5)Sorry for a late follow-up here (been traveling) but I found a picture, without too much more information, of the transfer switch which you have. It appears it has wired cords on the two "hard-wired" connections and is basically designed for RV/marine applications where this type of connection is common. I'd simply put a plug and outlet connector on the appropriate cords and make this a plug-in device. Not sure about the 300 watts being able to power the pellet stove (fans, igniter, and auger) as pointed out above, and an alternative power-source to recharge the battery during an outage. Just had our first storm last night (early in the season) and while I do have a pretty good portable generator/hard-wired transfer switch setup, I wasn't quite ready for 11 hours of it... however, the gas cans are now full!...See MoreExtra Outlet
Comments (17)What are you smoking today? Your advice on the other thread was potentially dangerous/destructive, this one is just wrong. The two DP breakers there are rated 40 and 30, which are quite likely the range and dryer circuits added recently. It's not an old service. QO panels are current equipment, and this one looks to be in relatively new condition. Your guess is most likely not correct. A 240V circuit to one "yoke" requires that the handles be tied - ie a DP breaker. It is legally impossible that there is another 240V circuit in the house running off two seperate SP breakers. If we theorize that there is, then we must conclude the OP's partner's father is a very poor electrician indeed, which negates the suggestion that we should further seek his opinion. The OP references "two air conditioners". I think this implies window units, probably 120V models. Hot water is probably provided by oil, propane, natural gas, etc. There are no tandems in place. Do you even know what a tandem breaker IS? It's two breakers that fit in the space of one. Look at the picture. Click on it and it gets bigger. Do you see a single space with two handles? No? Neither do I, so there are no tandems in use. The blank is available unless the 40A breaker there is a 'shunt-trip' type (which occupies an extra space next to it). I can't imagine why they'd want a button to remotely trip the RANGE breaker, so I'm going to go ahead and assume this is not the case. There remains one slot open. All of the other advice given thus far in this thread is good. My suggestion is to obtain one QOT120 tandem breaker, install it in slot 15 (assuming that slot accepts tandems on this model), move circuits 14 and 16 to it, then install a QO220 into slots 14/16 to power the suggested baseboard heater. The reason I am suggesting 14 and 16 is because the ratings on their handles are clearly visible in the photo and I can be sure they are 20A circuits. If #12 is 20A also, you could just as well install the QOT in slot 11, keeping circuit 11 there and moving circuit 13 to it also, making 13/15 available....See Morejemdandy
