A new robotic wheelchair will go where no wheelchair has gone before--climbing over curbs and tackling stairs. The wheelchair will feature four independently powered wheels mounted on five axes. Sensors next to the wheels will scan obstacles to determine if they can be rolled over, signaling the wheels to change to legs if necessary. An on-board computer will help keep the chair steady and the legs properly aligned, allowing the legs to step on or over the obstacle. The legs will...

Such a situation seems to have happened to everyone... You have been watching a football match or some other sports event for nearly two hours and nothing spectacular has happened. So you decide to go and fetch a beer. The moment you're in the kitchen, you hear the commentator yelling and the audience roaring. You forget about beer and run back to the living room to see what's going on, but by the time you're there it's all over. Of course, they might show you a replay, but it's not the...

The device will be a combination of phone charger and LED flashlight, merging two useful objects into one and perhaps making it easier to find your phone in the dark. The device itself will be charged by a USB port, reaching a full charge in about 5 hours. It will be controlled by a single button, and a blue LED will flash to indicate phone charging. The same single on/off button can be held for two seconds to operate the flashlight, which will consist of a 1W LED.

I wish we had a store where it was possible to buy all the staff for the case of disaster. People would be able to find some special devices there, i.e. modified in some way so as to be the most helpful. For example, an ordinary flashlight could combine a radio and a cell phone charger as well.

Why not create piezoelectric artificial trees able to collect rainwater and generate electricity? The tree will be able to use water from rainfall as well as the natural water table as irrigation; wind energy will provide power for the LED lights.

The new pod makes catching big waves easier, adding a bit of thrust to allow the surfers to reach big waves without the need for a tow. The device is designed to fit on a variety of boards, including surfboards and rescue boards. It fits flat against the underside of the board and relies on a pair of aluminum impellers to provide up to 20 lbs of thrust and 12 mph of speed. The surfer controls the device through a wireless wrist worn remote control, and the rechargeable battery...

My idea is to create a blanket which can change the temperature whenever we want. Such a blanket will retain the warmth in the winter and keep our body cool in the summer.

A new solar panel system will be able to track the sun while floating on the surface of artificial waterways, increasing efficiency without taking up any space on land. The floating panels will use reflectors to increase the efficiency of the solar energy capture during different times of the day. The panels will also use the water to help stay cool, reducing costs to 20 percent less than conventional, ground based systems.

Below are the tips which helped me greately to stop smoking: * Inform someone that you're going to quit smoking. By telling people, you are not only making the commitment to yourself, but to others as well. After that, make sure the people you hang around most often are aware of your plan. You'll be surprised how supportive people are, even if they themselves are smokers. * Define a quit date. I recommend giving yourself somewhere in the vicinity of two to four weeks. This...

A new sort of super glue for molecules could be created using the same bacteria that eats flesh and causes strep throat. The idea is to develop the binding agent by isolating the protein FBab from the Streptococcus pyogenic bacteria. The FBab protein creates a chemical bond between amino acids, and attaching fragments of the proteins to molecules will create a bond powerful enough to withstand chemical detergents. The technology could eventually be used to join enzymes on...
