Vending business occupies a leading position in the list of the most profitable and popular types of the third millennium business. Through vending machines you can buy almost any product, ranging from household appliances to fresh products, such as pizza, carrot and even meat. Manufacturers of vending machines are constantly improving machines and accommodating them to the customer needs. A good example of improved vending machine can be the one which appeared on one of the...

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...

The idea is to create a lighting system able to alter its lighting automatically based on the emotional flavor of the room. The lighting system will consist of some the world's most efficient and compact lights. The lights will be equipped with sensors to alter the lighting based on the number of people in the room. The sensors will also be able to read the emotional environment of the room, and adjust the lights to suit the mood.

Why not create 'air conditioned' clothing as a way to deal with the restrictions on electricity during the summer heat? It is possible to develop jackets and shirts, as well as cushions and mattresses, with built in fans. The jackets will include two electric fans powered by a lithium ion battery pack. The fans will draw the air in at up to 20 liters per second, circulating it through the jacket where it will dry off sweat and evacuate through the collar and cuffs.

Why not create an electric drive that can be attached to any manual wheelchair, creating a long distance alternative for wheelchair users. The drive will resemble a pair of headphones, with two circular hubs connected by a curved section. Each hub will contain a 24-volt motor powered by a lithium-ion battery with a range of almost 20 miles. When attached to the center of the wheelchair's wheels, the device will be able to propel the wheelchair at speeds up to 12 mph. Steering...

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).
