Extreme tourism is at the height of its popularity today. This popularity is easy to be explained as extreme form of entertainment is the opportunity to experience the "thrill" that is missed in everyday life... this is emotions boom, risk and awareness of one's greatness and weakness. Extreme tourism is for the strong and courageous, for those who love risk and danger, who is not afraid to test his endurance. A new extreme attraction has been opened in the Australian city of...

The idea is to create a palm sized hearing device that will include an array of noise management systems but will look like a common mp3 player. The device will be easy to use, featuring an LCD screen and headphones with integrated microphones. It will include noise reduction and will be able to control feedback and wind noise. The device will also include a special function that will adjust to the changing environments of standard, music, indoors, and party.

Why not develop a new lithium-ion battery able to store more energy than its predecessors without overheating? The battery will use a graphite current collector and imide salt in the electrolyte of the battery, which will increase the life of the battery as well as allowing it to withstand high temperatures. The battery will have an energy density of 225 watt hours per kilogram; 50 percent higher than the lithium-ion batteries used in electric vehicles.

My idea is to create an application for smartphones which will use phone's GPS and accelerometers to sense and pinpoint the location of potholes. The great challenge there will be how to teach the phone to tell the difference between a pothole and a speed bump or sewer grate.

A new catalyst able to extract hydrogen from urine was discovered. I suppose it could have applications as fuel and as a way to clean municipal waters. An inexpensive form of electrolysis is to be used to break down urea, which contains four hydrogen atoms per molecule. A nickel based electrode will oxidize the urea, and then a voltage applied across the cell will break down the molecule. Since the hydrogen bonds in urine are weaker than those of water, urine is a less...

An integrated chemical chip able to regulate the delivery of neurotransmitters could be implanted in the body to help control muscles chemically. The chip will be built upon previously developed ion transistors able to transport both positive and negative ions as well as biomolecules. By combining two transistor types into complementary circuits similar to traditional silicon-based electronics it is possible to create an integrated chip able to work with common signaling substances...

I want to have a battery charger to recharge standard alkaline batteries. This will keep them from the landfill for a little while longer. The charger will use a microprocessor to control the trickle charge and prevent overheating and will be able to charge both AA and AAA batteries. The charging cycle will take about 4 hours depending upon the quality of the battery and amount of charge left in it. The device will also recharge Ni-CD, Ni-MH, and RAM batteries by automatically...

My idea is to create a mobile phone application based on GPS which will help to define single people within a radius of 0.5 - 0.7 miles. It will be of great help not only for pickups but also for people who are eager to make the acquaintance. The application will also have a chat function so as it is possible to send short messages to each other and make an appointment.

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 device to project a laser image onto the road in order to make drivers more aware of bicyclists. The device is meant to be mounted on the handlebars of a bike, where it will project a bright green bicycle symbol on the road in front of the cyclist. The symbol will be visible by day or night, and will shine steadily as well as flashing off and on.
