Prototype SunCat batteries enable solar charging

Solar-powered phones like the Samsung Blue Earth are great eco-friendly concepts, in theory.

But let's be frank with ourselves. We won't see these sun-worshipping devices replacing mainstream handsets in the near future. Meanwhile, we still have a mountain of gadgets that need to be juiced regularly, which is why designer Knut Karlsen's idea of integrating flexible solar cells onto rechargeable batteries could be a more immediate solution to reducing our carbon footprint.

Have your way with Windows

If your computer handles a heavy load of programs, deleted files, and temporary downloads, asking Windows to do your bidding is akin to disciplining a two-year-old child. You'll get your way in the end, but only after some resistance. Here are six top-rated, perfectly legal performance enhancers for Windows XP and Vista that help you regain control.

Easy Vista ManagerLaying out a smorgasbord of tweaks for all your computer's categories, this premium, easy-to-use performance-perfecter has Vista's particular traits in mind. Each of Easy Vista Manager's categories, ranging from hardware and software to network and security, is chockablock with detailed information about your computer and what you can tweak, including a few surprises that might help you save on energy overall--your own and the computer's. While the 20 use trial period isn't the most generous we've seen, Easy Vista Manager's thorough view into Vista's ins and outs makes it well worth the download


RAMBooster
While most of the all-in-one optimizing applications include a tool to rev performance by freeing up choked RAM, you can do that on your own with a freeware program like RAMBooster. The small application may register as a little old-school, but it has what it takes to give your PC some extra fire. RAMBooster includes a few program defaults for those still new to the process, but you can modify them to your liking. An icon in the system tray serves as your memory conscience, gleaming red and black if all's well. As your quotient of available memory falls, the icon switches to yellow, a sure sign it's time to do some tweaking.



Glary Utilities

A brawny freeware application, Glary Utilities will helpfully put the squeeze on inefficient settings without charging you a cent. The good-looking optimization suite includes a Registry cleaner, and a privacy minder that sweeps away Internet Explorer tracks. In addition are tools to cut out junk files, remove invalid and dead-end shortcuts, and manage start-up programs. A file-shredder is also included, to securely reduce deleted files to ribbons. While you'll be able to perform many of the same actions from Windows' various maintenance folders, Glary Utilities and its optimizing kin conveniently centralize the tools and streamline the process.



Auslogics BoostSpeedBoostSpeed supersizes Auslogics' freeware disk defragmenter and Registry defrag into a strong package that includes some services unique to this all-in-one premium download. If you're already a fan of Auslogics' applications, its free-to-try suite will not disappoint. Optimizing the program's RAM, disk space, and Registry are Auslogics BoostSpeed's top tools, along with the file shredder and performance monitor. In addition, the application features a decent uninstall manager, start-up manager, browser tweaker, and manager for customizing Windows' interface and routines.



PerfectDisk

A defragmenter at its core, PerfectDisk tops robust performance-tending features with an attractive, logical interface. Its defragger comes equipped with a tool to analyze your data patterns and to use that information to more efficiently store your data in the future. This tack introduces a preventative element that helps lubricate your PC's internal gears. Offline defragmenting is another key feature of this free-to-try application that can optimize parts of your drive that can't be touched while Windows is going.



Tune-Up Utilities
TuneUp Utilities 2009 earns high praise for its capability to get to the heart of Windows' maintenance tools in a faster, prettier, and easier-to-use format. The modules tackle temporary files, superfluous registry entries, and start-up routines, and do so in a way that gets you maximum speed. In addition, the free-to-try application also packs on a host of performance accelerators, enhancers, and tweaks. There's also a file shredder, file recovery tools, and a tool to quickly analyze your problem areas. A button programmed with general presets gives those new to the optimizing game a one-click option for boosting performance.

Top 8 Ways to Speed Up Your Computer

Over time, the speed of computers with Microsoft Windows can decrease. This appears as the system taking more time to respond to a user’s actions like opening files, folders, surfing the Internet and other tasks. However, there are things you can do to speed up your computer.
The following is a list of ways you can improve your computer's performance. These steps are intended to be used in order. The key is to do the simplest and least invasive thing first until your system starts responding better.

Golden Rule: Do No Harm
If you want to improve the speed of your computer, that’s great. However, above all, do no harm and beyond the scope of this Windows forum, ask for help from those you know if you get in over your head. Remember: you have time. You can stop most processes I discuss without causing harm. Caution and common sense go a long way when working with computers; problems are often much easier to fix than they appear.

Steps to Speed Up Your Computer’s Performance
1. Make Sure Your Hardware is Sufficient
Above and beyond everything you can do with software to optimize the function of your computer, making sure you have the proper hardware to support Windows is critical. Here are minimums that I recommend:

For XP – A computer with a Pentium processor, at least 512MB of RAM (operating memory), preferably 1 to 2 GB of memory and an 80GB hard drive or larger.


For Vista – A computer with any dual-core processor, 2 to 3 GB of RAM and a 160 GB or larger hard drive.
These hardware configurations will minimize Page Filing (swapping programs in and out of memory and onto the hard drive) and assure that your computer has enough horsepower to run the operating system. Upgrading memory (RAM) is the cheapest and easiest thing you can do to improve the performance of your computer.

2. Clean Your DesktopIs your Windows Desktop dotted with files? Have you noticed that your computer has been running slower and slower? Do you see the hard drive light often flashing while you wait for the computer to respond to an action? There are steps you can take to fix it. Read this article.

3. Scan Your Windows System for Errors
An operating system is a collection of files that perform different functions. It is possible, over time, that one or more of these system files has changed or become corrupted. If this happens, the speed of your system may decrease. By using a utility called “System File Checking”, it will inspect these files and correct any problem it finds.

4. Scan for Viruses, Spyware and Adware
Every Windows computer is vulnerable to viruses. Viruses are nasty little programs that cause both major and minor problems for users.

Spyware and Adware are programs created by companies to find out more information about customers, so they can better market products to them. Usually these programs are not created for malicious purposes. Spyware and Adware can load into computer memory and slow it down.

Periodically scanning and removal of Viruses, Spyware and Adware is a great way to improve computer performance.

5. Uninstall Unused ProgramsOver time, you may have accumulated programs on your computer that you do not use. When a program is installed, it creates connections between the program and the operating system. Even if you don’t use these programs, they can slow down your system. If you have the original program’s installation disk or file, removing programs will free up space on your computer and may speed up your system's performance.

6. Adjust Visual Effects for Better Performance
Windows provides a number of interesting visual effects including animated windows and fading menus. If you do not have enough operating memory (see above number 1), these effects can slow down your computer. Adjusting or reducing visual effects can make a difference.

7. Don’t Automatically Start ProgramsPrograms use operating memory (RAM, also called system resources). Unless you always use these programs, you can keep them from loading at Windows startup and speed both the booting of your computer and its performance.

8. Defragment Your Hard Drive (After you have tried everything else)
The more information and programs you have on your computer, the more it is likely that Windows has placed parts of the same file in different locations on your hard drive. It may do this for hundreds of files and programs, depending on how much space is available. Defragmenting the hard drive places all information for each file in one place. The result can be a faster computer experience.

Important Note: Before you even try this, backup all your work onto a different computer, hard drive, CD or disk. Also, you should only do this if you have a reliable source of power for your computer. Doing this when there is a brown out or power problem in the neighborhood, is not a good idea. If a computer turns off while it is defragmenting a drive, it will create more problems than not defragmenting it in the first place.

Windows 7 shipping this Fall... according to Compal, anyway

While Steve Ballmer himself declared that Windows Mobile 7 would be coming out next year, we've got a somewhat less reliable source suggesting that the desktop version of Win7 will be landing this fall. Ray Chen, president of Taipei-based Compal Electronics, was quoted as saying that "according to current planning," Windows 7 should be on its machines by "late September or early October." For those unaware, Compal is responsible for crafting HP and Acer laptops, and honestly, we're not exactly sure how this bigwig secured these dates. Of course, it stands to reason that everyone else in the industry is either 1) clueless or 2) just better at keeping secrets. For what it's worth, we're taking this with a huge spoon of salt, and just between us, you should probably do the same.

Waterproof and Fireproof USB SentrySafe

I’ve always thought it would be cool to own a safe for all of my valuables. Especially one of the SentrySafes that are both waterproof and of course fireproof. The problem is that I can never really think of enough items to jam in the safe that I would like to keep safe from a fire. Well now it’s not only practical for paper files and jewelry, it’s also a great way to store data that you want to keep safe from thieves and damage from either a fire or flooding. It wouldn’t be a big deal to store an external hard drive and other items within your average safe. However, it doesn’t have the extra perk of a USB cord/slot.

Cool & Geeky Gadgets

Japanese cell phone maker KDDI has teamed up with Hitachi to one-up your iPhone as the iPhone can’t manage 3D content. The Hitachi WOOO H001 will show you 3D versions of your phone’s still images and video.
But that’s not all, the phone also will give you a 5 megapixel camera, Bluetooth, microSD slot, and a 1Seg TV tuner. No word on price, but the handset should hit the Asian market by spring.

It’s an interesting looking phone for sure. But how many of us are really hankering to see our pictures in 3D if it’s not in hologram form?

Solar energy

Solar energy is the radiant light and heat from the Sun that has been harnessed by humans since ancient times using a range of ever-evolving technologies. Solar radiation along with secondary solar resources such as wind and wave power, hydroelectricity and biomass account for most of the available renewable energy on Earth. Only a minuscule fraction of the available solar energy is used. Solar power technologies provide electrical generation by means of heat engines or photovoltaics. Once converted its uses are only limited by human ingenuity. A partial list of solar applications includes space heating and cooling through solar architecture, potable water via distillation and disinfection, daylighting, hot water, thermal energy for cooking, and high temperature process heat for industrial purposes. Solar technologies are broadly characterized as either passive solar or active solar depending on the way they capture, convert and distribute sunlight. Active solar techniques include the use of photovoltaic panels, solar thermal collectors, with electrical or mechanical equipment, to convert sunlight into useful outputs. Passive solar techniques include orienting a building to the Sun, selecting materials with favorable thermal mass or light dispersing properties, and designing spaces that naturally circulate air.
