A lot of times, we are stuck out in public without our phone chargers handy. This leaves us vulnerable especially when we need to make an important call. This idea about a twirling battery is really cool. The concept is to simply twirl the cell phone battery around a finger a few times for a quick bit of juice to send a text or make a call. 130 twirls will give you approximately two minutes of talking time. The same idea could also be applied to batteries for other devices.

I've just found out that there was a microbial fuel cell based charger developed. It can allow cell phones to draw their power from the dirt. The device uses a conductive surface that is able to harness the free electrons that are created by soil microbes during their metabolic process. Plans are to distribute the charging device in Sub-Saharan Africa, where many people have cell phones but lack power in their homes to charge them.

A new Ipad accessory allows the Ipad using chef to explore recipes and change pages without needing to touch the tablet itself. The Chef Stand + Stylus is made up of a stand with a non-slip rubber base and a magnetic tipped stylus. The stylus allows the user to wake up the device, turn pages, or scroll without needing to touch the screen.

The idea is to develop a back panel reflector that will harnesses solar energy to power laptop screens. A mirror on the back panel pointed at the sun will be able to direct the sun's rays toward the screen to add natural light to the LED backlight.

A new device will be able to analyze the sweat in a person's fingerprints and determine the substances in their body. The device will be small and quick, with the entire analyzing process taking only a few minutes, and will be powered by safe and disposable cartridges. The results will be linked to a record of the user's fingerprints, so the results will be difficult to dispute.

The lockable thumb drive will require the user to set its combination rings correctly in order to access the device. Constructed of a solid aluminum alloy, the drive combination lock will consist of five rings displaying every letter in the alphabet. The password will be set by the user and will be simple to change. The manufacturer will reset the device in the case of forgotten codes.

For many, the sound of the drill is a big cause of anxiety when it comes to visiting the dentist. I have an idea to create a device which will cancel out the noise of a dentist's drill helping people overcome their fear of a check-up. This new device will allow patients to listen to music on an MP3 player, while the sound of the drill will be blanked out. Patients will still be able to hear the dentist's voice because not all sounds are to be filtered out. The device will be...

I've just came across the idea of creating a laptop computer that can be rolled into a cylindrical shape The concept consists of a flat panel display wrapped around a central cylindrical column. A power plug detaches from the top of the column, the power cord also acts as the carry strap, and the speakers and USB ports are stored inside the column. Once rolled out flat, the device can be used as a 17 inch tablet computer or can be tilted into a notebook shape, with the lower half...

The idea is to create a portable ultrasonic detector that will use non-invasive technology to check gold bars for flaws or signs of counterfeiting. The device will use computer controlled phased array probe to produce easy to read images that even untrained personnel can interpret.

A designer from India invented a unique jeans design, which helps to protect wallets from pickpockets. The main feature of these jeans is that there is a copper wire in their seams. The wire is connected to a special device consisting of capacitors, a 3-volt battery and a magnetic switch. This electric device is placed in a case and can be activated by the user at any time. Its mechanism of action is simple - once a thief feels about for the wallet in your pocket, he is...
