When Nikola Tesla built the Wardenclyffe Tower in 1901, he was on to something that was way too advanced for the early 1900’s with the development of a wireless communications tower, broadcasting, and also demonstrating the transmission of power without interconnecting wires. Wireless communications is revisited today with our vast cellular phone and wireless technology. Wireless charging looks like the next step in to the future to power small gadgets and devices.
Dr. Matt Reynolds, who is an assistant professor in the electrical and computer engineering department at Duke University, has developed safety gadgets for construction workers. The wirelessly powered safety gadget is a called a SmartHat and is worn by construction workers to alert them of dangerous construction equipment that is nearby them. The SmartHat has a built in beeper and microprocessor with no batteries and is powered by radio waves that are naturally occurring in the air. Big bulldozers and backhoes have wireless network transmitter installed on them and when they get close to a construction worker wearing a SmartHat, the beeper will sound off.
Harnessing radio waves to power small devices may not be anything new, but it is promising to think up of wirelessly powered cell phones, laptops, digital camera and other small devices. The other question is how big of a device can run off of only radio waves? Only time and innovation will tell with our drive to alternative energy power sources.
Dr. Reynolds of Duke University stated: “We are on the cusp of an explosion in small wireless devices than can run on alternatives to battery power. Devices like this can live on and on."

Electronic devices powered by our human bodies are within reach for some scientists. Several gadgets are being researched and developed with examples such as sensor studded clothing to give off vital signs and movement signals, a disposable electrocardiogram machine the size of a Band-Aid that monitors a patient's heart, a cell phone implanted in a tooth, contact lenses with heads up displays, and other miniature electronic devices that can plug people into computer and communication networks. Using regular batteries to power these devices is out of the questions, so new ideas are being researched and developed to scavenge energy from the human body.

Motorola has released the Droid X today at all Verizon stores nationwide. The Driod X now joins the iPhone 4 and HTC EVO 4G in the battle for the superphone top spot. Apple's iPhone is flawed with reception problems on the AT&T network and could result in users switching over to Verizon to purchase the HTC Android X. July and August should be interesting months to see how well the Droid X sells to consumers.
Battery life on the Droid X is impressive with an eight-hour talk time and 10 days standby time. The Droid X is equipped with a 1540 mAh Lithium (Li-ion) battery, which is bigger than the 1500 mAh Evo 4G Lithium (Li-ion) battery and 1420 mAh iPhone 4 Lithium (Li-ion) battery. This should put the Droid X ahread of the iPhone 4 and EVO 4G by actually having a cell phone battery that will last throughout the whole day.
Motorola Droid X Pros:
- Long battery life
- Google Android OS v2.1
- Bright, colorful, glossy 4.3 LCD screen
- 8GB built-in memory; 16GB card pre-installed
- 8-megapixel camera with dual-LED flash, HD video recorder
Motorola Droid X Cons:

Technology is always advancing with faster processors, more memory capacity, and longer lasting batteries, giving the consumer a portable electronic device that is at it's peak innovation. Digital cameras will always fall in this category as the megapixel size will always increase every time we run to the electronics store to check out what's the latest and greatest digital camera out there. If we rewind all the way back to the first digital camera aimed at photojournalists in 1991, we would see the release of the Kodak digital camera system DCS 100 that was equipped with a 1.3 megapixel sensor using a Nikon F3 camera. In 1994, the Apple QuickTake 100 camera was one of the first digital cameras to connect to a PC via serial cable available to the consumer market. The Kodak DC40 and Casio QV-11 followed in 1995, and Sony Cyber-Shot Digital Still camera in 1996. So, back to the question of how long do digital cameras last?
Picture of the Kodak DCS 100 with the Nikon F3 Camera 1991:
Digital cameras can last a very long time if they are taken care of properly. It is not unheard of to get 5 or more years use out of your digital camera. After 3-5 years, the batteries will have trouble holding a charge. Many people will purchase a replacement digital camera battery to get the full camera use out of one charge. While others will store or sell old digital cameras because there are faster, higher resolution, higher capacity, and improved digital camera designs with limitless photo options available at such bargain prices. Most digital cameras come with a lithium-Ion battery and can be discharged / recharged 300-500 times over a lifespan of 3-5 or more years. Some digital cameras take disposable AA batteries and can use rechargeable AA Ni-MH or Li-ion batteries that can last just as long. Digital cameras are very fragile and should be put in a storage case after each use. Digital cameras do not like to get wet with spilled soda or left in direct sunlight. Your digital camera will last a very long time if it is well taken care of for each use.
Some people like to have the latest and greatest digital camera. Every few months new digital cameras are released and can become expensive to buy a new camera after every release. Some of the latest digital cameras are the Sony Cybershot DSC-W370, Canon PowerShot A3100 IS, Kodak Slice, Olympus SP-800UZ, Samsung NX-10 and many more brands that look absolutely amazing. Many of these cameras are exceeding 13-14 megapixels with incredible image quality and high speed picture snaps. Not to mention how cool the new digital cameras look with their giant LCD touchscreen features and slim cases. It's probably safe to say a new digital camera purchase should last you 3-5 years before replacing it with something new on the market.
