It is a concept easy to grasp at: it is a system designated to create power out of the Radio Frequency energy in order to charge batteries. Since we are surrounded by these Radio Frequency devices the potential for creating this system is rather immense. People that need to charge their batteries on regular basis can have this system at handy. Some of the items that create Radio Frequency are WiFi and cell phone antennas, items that are of common use at home and not only.

The Nokia Prototype, a device for the future, is planned to be conceived to generate power from the Ambient Radiation, thus being able to charge batteries without needing an AC outlet. Markku Rouvala, a researcher from the Nokia Research Centre in Cambridge, UK, together with a group of researchers strive to develop a way through which phones are capable of topping off their batteries by taking power from ambient RF signals.

The type of radiation could come from usual devices, such as: WiFi transmitters, TV antennas, cell phones… Markku Rouvala affirms that the device they had developed, now at the stage of a prototype, could get as much as 50 milliwatts of power. This power would be enough in order to charge a phone that is switched off. He also said that even if one is getting microwatts, one is still able to gather energy, as long as the circuit doesn’t use more power than it’s receiving.

This method of generating power is not at all a new discovery; this method is being used to produce power for wireless sensors and RFID tags. According to Technology Review report, a researcher at the University of Washington created a temperature and humidity sensor that was capable to take the power it needs to activate from a signal that was emitted by a 1-megawatt TV antenna at 4.1 km distance away, but the device required only 60 microwatts.

The Nokia prototypes are to be planned to generate much higher levels of energy from ambient signals, such as the Radio Frequency that can become a energy source for battery power. To obtain 50 milliwatts would need around 1000 strong signals and an antenna able to get such a wide range of frequencies.

On the other hand, researcher and physicist Steve Beeby, is working on vibrational energy and he affirmed that if the other researchers could get 50 milliwatts out of RF Ambient, then he would definitely be put out of business. Rouvala states that it was possible to insert this into a product within a period of three to four years. This technology to be created would not be applied to power a phone alone, but it would be combined with other energy-gathering technology like solar cells.

Carrying around a laptop and a standard projector isn't something I'd wish to anybody else than my enemies, but since I don't have any enemies, I thought it would be a good idea to tell you about a pocket projector. Sure, there's nothing really new about pocket projectors, only that you don't get to see such things too often...

... and since $280 is really a decent price for a projector that you can take anywhere, let's check the FAVI mini pocket projector now, shall we?

Shortly called FAVI PMJ-1000, the pocket projector pictured above comes with the following specs and features:

- 4.4" x 1.9" x 0.6"
- 180 grams
- can connect to PC/laptop, as well as video games, cell phones, DVD players, iPod Touch, iPhone and more
- Image Size (diagonal) 6" - 100"
- Contrast Ratio: 80:1
- Max Compatible Resolutions: 800 X 600, 1024 X 768, 1280 X 800
- Luminous Flux: 12 lumens

For your money, you'll get 1 year Parts Warranty, and 45 days Labour Warranty. Also covered by a 14 days Money Back warranty, the $280 pocket projector here could become your next best friend. My final confession is that I don't buy things I don't really need, and I am really sorry because I don't need a projector, because it would really be a pleasure to own my friends with this pocket beauty... really!

One of the things I always hated about USB drives is the fact they can't fit inside my wallet, and if they do... I obviously end up with a fat pig wallet inside my pocket. Now, things have changed a little, and I am sure most of you would really enjoy having some flash memory... as large as a credit card!

Introduced by TopTech Products as "World's Slimmest, Most Convenient USB Flash Drive," the Slim Data USB Card is a very interesting addition to anyone who's on the road for long periods of time... but also to those who want the kind of "USB credit card" nobody in the neighborhood has!
<-300x250 Medium Rectangle - center->
Available in blue, "smoke" gray, red, and clear finishes, the Slim Data has only 4GB in size, but since you'll get a limited lifetime warranty with that... I guess it can't be that bad. After all, think about these - $24.99 price, made of durable transparent plastic, fully supported by Windows, Macintosh, and Linux, USB 2.0 and 1.1 compatible... and able to fit inside your wallet just like a regular credit card!

If all the above isn't enough to make you want such a great product, then I guess you'll do what I have done - get some 8 GB flash drive, and then carry it around in your pocket. Just one advice - be extremely careful with your little gadget, because we all know how bad can be to see your precious data disappearing...

I love Dell. I don't know how many times I told you before, but here it comes again - I love Dell! Even more, they don't even pay me to love them... it's something like your mother's love, haha! Anyway, Dell is not my mother, and they earned my love and respect by releasing a bunch of outstanding products, and being lucky enough that I missed all their bad ones.

Now, that we settled the problem regarding my feelings towards Dell, let's check the Dell 4310WX, shall we? Before moving on, just another confession - I never had the chance to work with a Dell projector, but since prices are going down, I may get one...

The Dell 4310WX DLP is now available for purchase, and it comes for a not-so-small price of $1,099. What will you get for this sum? Good question, so let's see the main specs of this projector:

- 1,280 x 800 resolution (16:10 aspect ratio)
- 3,500 lumens brightness
- 2,000:1 contrast ratio
- remote control with integrated laser pointer
- one VGA input
- two component/analog D-sub inputs
- HDMI 1.3 and DisplayPort input
- Ethernet jacks
- 5W built-in speakers
- 280W bulb rated at 2,000 hours (regular usage), or 2,500 hours (Eco-Mode)
- password protection option and Kensington lock slot for security

Apart from allowing you to move around in presentations without breaking a sweat with the help of the remote control, the Dell 4310WX also comes with closed captioning support, allowing deaf or hard of hearing watchers to easily follow the dialogue.

Regarding its design, the Dell 4310WX seems a bit bulky and with a dusty look, but that's just me. After all, I still have an old Dell CRT monitor somewhere around, and despite being bulky and with a dusty look, it works like a charm... after almost a decade! While the 4310WX won't probably work for as long as that monitor, 2,000 hours ain't that bad - almost 2 years with a daily running time of about 4 hours.
