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.

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.

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 a device which is attached to a tire and study its pressure, compare it with an ideal one, check if it is intact, etc. and fix the problem once it is detected.

The idea is to create polymers that could be used to make paint that can heal its own scratches when exposed to UV light. The new polymers are to be using a method known as supramolecular assembly. Polymers made of small molecules will be formed into chains bound by metal ions. When these molecules are exposed to UV light, they will become temporarily unattached, forming a liquid that will fill in the scratches in under a minute. The molecules will reassemble and resolidify once...

The underwater heart rate monitor will work without chest straps, using instead an infrared sensor attached to the earlobe and capillary activity to measure heartbeat. The heart rate monitor will be attached to the strap of the swimmer's goggles, where it will monitor the heart beat and communicate the rate by a voice transmitted by bone conduction technology. The rate will be communicated as the swimmer moves, and will be set to deliver the information from every 10 seconds to...

I travel a lot and often use my digital camera to take pictures of landmarks and the landscape. All the pictures are time stamped to tell me when they are taken but there is no information on where they are taken. I think that building GPS system into cameras could be cool. This will help to store the location, direction and possibly the pitch and also will add more life to the pictures. By the way, it may be possible to create a 3D map using this technique in future.

I am fond of these Discovery channel programs when they show night life in forests. This seems to be so exciting. I suggest organizing some kind of night tours and let tourists observe animals do their staff at night (it is advised to use night viewing devices so as not to scare them away with flashlights).

The idea is to create a camera clip which will allow photographers to access their cameras quickly and easily. The clip will secure the camera to the user's belt by a plate attached to the bottom of the camera. The camera will be released by quick release button, and a twist lock will be engaged to prevent accidental release. The clip plate will be also compatible with any Arca-Swiss style tripod head.
