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.

I would definitely consider the new ultra books in particular the Asus ultra book that is both a tablet and laptop in one it won't be cheap but for travel the size and weight will be important, I think you should go with 8,it will hard to find new with out it. I would definitely not get 17" for travel. I think anything in the newer released laptops will cover your needs. The ultra book convertible is the best of both worlds, I think being able to use it in tablet mode will come in very handy. I personally own the Asus tf300 transformer tablet which I love but you want something bigger it sound like and your gaming needs would probably dictate a laptop. I don't mind a refurbished as long as it is factory refurbished with some warranty.

make sure your camera is able to utilize the full 4 gig I know most of the earlier ones can not use larger than a 2 gig card, my cannon can only use up to 2 gig cards and it is not very old. The format of some of the new very large size memory cards is not accepted by many cameras. Look up in your camera documents and manuals to find the max size card it can use and the formats. Also make sure you format the cards using the camera you will be using it with. when googling your camera I found this info "Length limited only by storage (maximum single movie file 1GB) Â AVI (Motion JPEG compression)" so you can not do a movie file larger than 1gig. Canon PowerShot S3 IS Review more about your movie mode Movie functions Powerful video functions make the PowerShot S3 IS far more than just a high-performance digital still camera. A dedicated movie button means users do not need to switch modes to start recording, so spontaneous moments can be instantly captured in full motion. Users can record smooth 30-frame-per-second VGA quality movies of up to 1 GB with stereo sound, or create 60-frame-per-second QVGA clips for sharp slow-motion playback. The Movie mode also allows users to pre-select exposure and white balance, zoom throughout the camera's focal range, and manually adjust focus while shooting. A Photo In Movie feature enables the capture of full resolution digital stills during video recording. also with mine I make sure to only buy the High Speed SD cards it makes a world of difference, they are more expensive but so very worth it. the higher the speed the better.

Adware: Computer script, code, or program which delivers banners or other types of advertising to a users computer. Delivery of the adware is often accomplished when program developers include the script, code or program as part of an application, and can also be contained within cookies received from some websites. Adware should not be confused with the free program "Ad-Aware" from Lavasoft, which can detect and remove adware and many other types of intrusions. AntiVirus: A software program which helps protect a computer against being infected by a virus. BIOS Basic Input/Output System is the program which runs when you start your computer, and which communicates between the devices in your computer. The system BIOS is normally stored in an EPROM chip (Erasable Programmable Read Only Memory) located on the motherboard. Browser: A software program used for viewing Internet websites. Popular programs include Microsoft Internet Explorer, Mozilla, Opera, Firefox and Netscape Navigator. Cache: A place to store something (more or less) temporarily. Web pages youve visited are stored in your browsers "cache" directory on your hard drive. ISPs (Internet Service Providers) sometimes cache web pages, which speeds up access times for users since the page is being read from cache memory and not downloaded from the actual web site. Web browsers usually have an option to let you adjust the size of your browser cache file. CD: Compact Disc. Most often used for music and photo formats, but also used to store other types of data. See below. CD Burner: A CD drive that is capable of writing data to a CD (Compact Disc). The process if often referred to as "burning". A small laser is used and the process does generate a small amount of heat, hence the term. CD-R (Read Only). Once data is burned to a CD-R, the CD cannot be over-written with new data. CD-RW (Read and Write). Can be used repeatedly. Data may be erased and re-written, much like the older floppy disks. Client: A software program that is used to obtain data from a software program on another computer. For example, Internet Explorer, Nestcape and Firefox are a type of Client. Codec: Video and Audio. Short for compressor/decompressor, a codec is a program used for compressing and decompressing data. Codecs can be used in software, hardware, or a combination of both. Some popular codecs for computer video include MPEG, Indeo and Cinepak. It is normal to have multiple Codecs for audio and video installed on your computer. Cookies: Cookies are small text files that Web sites place in the browser cache, so it can recall specific information. Typically passwords and user IDs are stored. They are also used to recall preferences for page content or personalized pages. Cookies can also be used to build a profile of which sites you visit and which banner ads you click, if any. Advertisers use this information to deliver targeted ads. Some sites use temporary cookies (called session cookies) that are deleted when you exit your browser. Others place persistent cookies which remain on your hard drive until you delete them. Cookies are not generally considered to be Spyware unless malicious or intentionally intrusive. Please refer to the definition of Spyware. Copy: A secondary representation of an original. If you copy a file or a folder, the original is not usually erased. CPU: Central Processing Unit. The main processing chip of a computer which plugs into the motherboard. Its speed is expressed in Megahertz or Gigahertz. For example, older computers may have CPUs that are rated at 300-600 Megahertz, which is considered slow by todays standards. Current CPUs are generally 1.5, 2.0, 2.5 Gigahertz or better. Many people refer to the entire computer case or tower as a CPU, which in broad terms, is acceptable. Desktop: The operating system user interface, which is designed to represent an office desk with objects on it. Rather than physical telephones, lamps, in/out baskets, etc., the operating system desktop uses program and data icons, windows, taskbars, and the like. Basically, it is the screen you see after your computer completely finishes "booting" or starting up. Desktop Icon(s): Generally, desktop icons are shortcuts. A shortcut is a "pointer" to a file. Creating a shortcut allows you to quickly access a program or document no matter where it is stored. For example: you might create a document using Microsoft Word and then store the document in a folder called C:\My Documents\ My Memoirs. Instead of having to search through your hard drive and folders to find the file each time you want to work on it, you can place a shortcut to the file on your Desktop. When you wish to work on the document, you simply click on the shortcut to open the file. Remember, a shortcut is simply a pointer. Deleting a shortcut will not remove the original document or file from the computer. However, some Icons on the desktop are programs and while Not recommended, some people use the desktop as a place to store files, programs, and downloads. To determine if a desktop icon is a shortcut or an actual program file, use the mouse to right-click the icon and then select "properties". If the icon is a shortcut, a shortcut tab will be visible. DVD: Digital Video Disk. Used to store Digital Videos such as Movies etc. However, new technology is allowing DVDs to be used for other things, such as storing data, music, etc. If it seems confusing, that is because it IS confusing. Manufacturers are still trying to agree on standard formats. Current DVD formats include: DVD+R, DVD+RW, DVD-RAM, DVD-R, DVD-RW, DVD-ROM. Perform a search using a search engine on the Internet, with the words "DVD Formats". You will find many sites further describing the technology. Download: To transfer data from a remote computer to your computer. Driver: A "driver" is simply a file (software) which contains instructions to control a hardware component or peripheral device of a computer, such as a modem, disk drive or printer. If you do not have the current device driver for a specific device, the device may not function properly. Very often, drivers..or updated drivers...can be found on a manufacturer's homesite for a particular device. Just as often, updated drivers are not listed because they do not need to be updated...or the manufacturer has not issued any updates. It is a good idea, when installing a purchased device such as a CD or DVD drive, to visit the manufacturers' website and check for updated drivers for the specific device. Error Message: An error message is a warning which is displayed whenever an error occurs during the operation of the program. A record of the type of error, its location, and its cause, is normally stored in an error log. Very often, the error log can be found within the programs folder, and can be viewed if opened with Notepad. Fatal Error Message: A system or application (program) error which stops or locks-up the computer and will normally be resolved by restarting the computer. Ordinarily, there is no permanent damage to the computer itself. A fatal error indicates a major problem with an application or program. A fatal error can also be generated due to some hardware problems. HDD: Hard Disk Drive. See next definition. Hard Drive: (Hard Disk Drive or HDD) The main device a computer uses to permanently store and retrieve information. Drives are sealed units typically found inside the computer. They may contain one or more disks within, depending upon the size of the drive. However, no matter how many disks the drive contains, the unit itself is considered to be one hard drive. To add a Hard Drive, one would install an additional unit. Older consumer hard drives started out small -for example 250 Megabytes- and were limited for a number of years, to approximately 2 Gigabytes in size. This was due to various technical issues. In recent years, the 2 Gig limitation has been eliminated, and drives of 80 Gigabytes or more are now common and affordable. Hardware: The physical and mechanical devices that make up a computer system, to include the CPU, motherboard, hard drive, monitor, keyboard, and mouse. IDE: Integrated Drive Electronics. A Hard disk drive with built-in electronics necessary for use on a computer. It includes on-board diagnostics. IDE also refers to the interface to which disk drives connect. Install: Adding a program to your computer which usually involves running an installation application for the desired program. For example, an installation file for the program "Irfanview" is named iview350.exe The 350 represents the version of Irfanview the installation file will install. The prior version of the program was iview325.exe ISP: Internet Service Provider. An ISP is a company that provides access to the Internet. For example: Verizon, Comcast, Cebridge, Direcway, MSN. ISP's provide dial-up, Cable, DSL, and Satellite service. Malware "Malware" is short for 'malicious software' and is usually used as a catch-all term to refer to any software which causes damage to a single computer, server, or computer network. Memory: Also referred to as RAM, or Random Access Memory. Enables a computer to store, at least temporarily, data and programs. The more memory you have, the more programs you can have running simultaneously and the more data can be held for faster access by your machine. Memory does not "remember" your data. Memory is dynamic, so when the computer is switched off whatever programs or data that were in memory disappear. You must save your data to a storage device such as a hard drive or removeable disk, if you wish to keep it after the computer is turned off. Hard drive storage space is NOT memory. Menu Bar: A menu bar is usually a horizontal assembly of words or icons you click on to open a menu or perform a function. They can be located at the top or your computers screen, the top of your browsers window, or at the top of a webpage. Motherboard: The main circuit board inside a computer, containing the central processing unit, the bus, memory sockets, expansion slots etc. Peripheral(s) A piece of equipment (mouse, printer, scanner, etc) attached to a computer to perform tasks that a computer cannot do itself. RAM: Random Access Memory: The most common computer memory which can be used by programs to perform necessary tasks while the computer is on. An integrated circuit memory chip allows information to be stored or accessed in any order and all storage locations within are equally accessible. RAM Types: Basically, there are two types: Dynamic RAM (DRAM) and Static RAM (SRAM). Dynamic RAM (or DRAM) is used for main system memory. SRAM: Used for Level 2 Cache. It is used as a computer's secondary (or L2) cache, which is a holding area for data outside the processor. It is not integrated into the processor as primary cache, so it is expandable. SDRAM: (Synchronous Dynamic Random Access Memory) is a newer type of DRAM that can run at much higher clock speeds than conventional memory. SDRAM synchronizes itself with the CPU's bus and is capable of running at 100 MHz. SIMM and DIMM: SIMM stands for Single In-line Memory Module DIMM stands for Dual In-line Memory Module. SIMM and DIMM simply refers to the way the memory is packaged (the physical appearance of the memory). SIMMs must be installed in pairs. For example, if you have eight RAM slots on your motherboard, you have to add SIMMs two at a time. You couldn't install seven SIMMs and leave one slot empty. DIMMs can be installed one at a time. Ram modules have contacts on them. They are gold or tin (a dull silver color). If you use one type, you should not mix them with the other type. There is parity and non-parity RAM. You can tell if your RAM has parity checking by counting the number of chips on the 'stick'. If the count is odd, you have parity checking. You cannot mix parity RAM with non-parity RAM. When handling RAM, it is important to keep the contacts clean, and not touch the contacts with fingers etc. Registry: A Windows database that holds configuration information. In simple terms, when you start your computer, the BIOS gives it an identiy by describing the devices it has available. The Operating System, or "OS" ( Win95, 98, ME, XP etc.,) then starts to "load", and it's configuration is defined by entries in it's registry. Software (programs) installed on the computer almost always enter values to the registry. Doing this allows the OS to knit everything together for a smooth running system. Therefore, it is important to properly "install" and "un-install" software (programs). Since the Registry is a critical database, it is usually ill-advised to make changes in it manually, unless the user is experienced in doing so. Ribbon Cable: IDE devices use a ribbon cable to connect to each other. Ribbon cables have all of the wires laid flat next to each other instead of bunched or wrapped together in a bundle. IDE ribbon cables have either 40 or 80 wires. There is a connector at each end of the cable and another one about two-thirds of the distance from the motherboard connector. Safe Mode: Safe mode is primarily used to troubleshoot problems with Windows by only running the bare essentials of the Windows operating systems and device drivers. Once entering safe mode, the user can execute commands and load devices one at a time. For example, if your Win98 computer "hangs" while booting, you can start in "safe mode" and load device drivers one at time to locate the problem. Safe Mode is also used to remove or delete files which are otherwise "locked" or "in use" during normal operation. Additionally, a "system restore" can be performed in safe mode which allows the user to restore their system to previously recorded settings. For most Windows computers, Safe Mode may be entered by continuously tapping the F-8 key as the computer "boots" or starts. Software: A program of detailed instructions which enable computer hardware to function. Spyware: Installs and gathers information from a computer without permission, and reports the information to the creator of the software or to one or more third parties. It provides the consumer with little or no control over removing the software. Spyware can change system settings, install keystroke loggers, collect and report consumer's personal information, use computer processing capacity without permission, and deliver spam or ads without consumer's notice and consent. Taskbar: At the bottom of the Windows screen, it contains the Start button, icons for open applications, the Quick Launch area, and the Tray or notification area. Trojan: A program that is installed without your knowledge and carries a destructive payload. Once your computer becomes infected by the worm or virus, it can be very difficult to repair the damage. Trojans usually come attached to another file, for example: .avi, .exe, or even .jpg. Many people do not notice or see file extensions, so what may appear as "fun program.zip" in reality could be "fun program.zip.exe." The difference here is the added .exe extension. Once the file is opened, the Trojan quietly installs itself. Title Bar: The band across the top of a window containing the title of the application in the window. Toolbar: A row, column, or block of onscreen buttons or icons that, when clicked, activate certain functions of the program. Ordinarily found across the top border of a program window. Tower: Vertical case for a personal computer often placed on the floor next to or under a desk. Uninstall: To properly and completely remove a program from the computer. This is usually done via the programs' own uninstall utility, or by using Add/Remove in Control Panel. Update: A new release (or version) of a piece of software that is generally understood to be an error correction release and does not contain new functionality. (as opposed to Upgrade) Updates are usually numbered by a change in the digit after the decimal. eg: V1.1 to V1.2 Upgrade: The process of installing a newer and more powerful version of a software package or hardware. It can also be a new and more powerful version of an existing system. Virus: A program capable of causing harm to files or other programs on a computer. A virus usually duplicates itself and may even change its name to avoid detection. Viruses arrive in a number of different ways, the most common of which are via attachments to E-mail. Windows Explorer: (Explore.exe) A file manager you can use to view and manage drives, folders, and files.
