Newbie with Possible(?) Rose Emergency
Comments (13)I think you'd be better off aiming for roses that need no chemical sprays, especially with small children playing in your yard, and especially if you imagine spraying and then walking into the house in the clothing you've been using for poisonous chemicals. It is possible to grow roses organically, though you have to be careful about which varieties you choose. If I had your problem, I'd mainly water and mulch well (maybe with tree bark if you can get it), while paying attention to which ones can make it under those conditions. For those that can't, then replace them with better, more disease-resistant varieties when you get around to it. When you mow now, throw the grass clippings toward your roses, and if you have any tree leaves anywhere, rake them over that way too. Fertilize next February/March with more organic "fertilizers" like alfalfa, grass clippings, tree leaves, and composted manure on top of your mulch, watering it in well. Then add more mulch on top of that. Enjoy your small children while you can! Any day now they'll be wanting to help you with the roses, and will have a great time doing your work with you. With this in mind, aim for low-thorn varieties with your eventual choices if you can. Best wishes, Mary...See MoreThe Long Emergency
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 MoreEmergency heat source?
Comments (26)I live in MN (slightly colder than WI), and always choose old houses (1910 at the moment), have had numerous power and furnace outages, and never have needed generators, propane heaters, etc. When the electricity goes out, my (high efficiency) gas furnace still works. If the furnace goes out, I turn on the electric oven and open the door, and put on more clothes. Best of all, I subscribe to the utility company's "protection" plan (e.g., covering appliances like the furnace, stove, refrigerator, and others) so that individual problems (vs. widespread ones) will be dealt with quickly (e.g., the last time my furnace went out, I called at about 10 p.m. and they came out at midnight, since the weather was cold). Most electrical outages are not so prolonged that you need to worry about the pipes, since the house retains some heat for quite a while, although they can be if there is an ice storm or a lot of wind & snow damage (but check to see if your furnace will still function before stocking up on things you may not need and that pose some risks of their own. Lots of caulk helps stem the leaks around doors and windows, as does replacing them with modern ones - I've done most of them by now (and can't throw away the wavy glass storms, which I've put back on three "replacement sash" windows (most were full replacement windows, which tends to fit tighter). Getting an energy audit is also a good idea to see where the problems are greatest and to prioritize any changes toward more energy efficiency. I would agree that gas inserts are nice, and do help with the heat....See MoreGenerator for Emergency Power
Comments (11)As I understand it, you're asking to create an extension cord from your RV, with both 240V and 120V outlets. You would unplug the pump from the house, and into the RV "extension cord". In this way, there's no way for the house power to be connected directly to the RV. I don't know of any way that you can provide both types of circuits (240 and 120) according to the NEC unless you install a sub-panel. However, to install wiring for just the pump, you could do this with 10 gauge 2-wire (plus ground). If you use UF cable, bury it to a depth of 24". Alternately, use individual 10 gauge THWN installed in conduit buried to a depth of 18". Then, at the outlet (and plug) end, simply hook the two conductors to the screws on the outlet (or plug) (the two conductors can be attached to either point). Connect the ground to the outlet (and plug), and also to the junction boxes if they are metal. There is no neutral in this circuit, and therefore no 120V power is available. If you decide to install a sub-panel, you'll need to use 3-conductor (plus ground) wire. Please see the FAQs at the top of this site for more information. Just make sure that whatever you do, that there's no way for the RV output to be connected to the house power....See Moredvd94
