An inflatable plug designed to prevent terrorist attacks could be used to help keep tunnels and subways from flooding. The flood-stopping plugs will be made using some of the same materials and processes that are used to make space suits. The plug will consist of three layers, which will help it maintain pressure, and will have a circumference slightly larger than the tunnel entrance, which will ensure a tight seal. It can be inflated using either air or water.

If your dog or cat has fleas, get fresh pine shavings and let your pet sleep for several days at these shavings. Fleas cannot stand the strong resinous smell, so they run away quickly. There is another way to deal with fleas. Take tobacco (you can crumble cigarettes for this) and make tobacco decoction. Then give your pet a bath with this decoction. Of course, the animal won't like such a bath but after this procedure relief from fleas is guaranteed.

A new concept vending machine will use face recognition to analyze passing people and attract them with targeted advertising. The vending machine will feature a 65-inch, HD, see-through display. The machine will use Audience Impression Metric (AIM) to recognize the demographic of people as they stand in front of screen, using the AIM information to determine the most attractive advertising content. When no customers are nearby, the vending machine will display a large clock...

If you are a person who travels a lot you know that it can be very tiresome to wait for the flight. Many flights depart with a delay; among charters the value of delays reaches 50%. If you wait for the flight in the check-in area you have to stand as there are no vacant seats there. Your legs and back begin to ache after standing for a long time. I can provide you with a solution to this problem. A suitcase with a folding seat of a Sitting Pretty series (Walkin'Bag trademark) are more...

The first front center airbag will be designed to protect front occupants in the event of a side impact crash. The airbag will deploy form the right side of the driver's seat, absorbing the impact energy between the driver and the passenger in the front. The airbag will also function as a restraint if the driver is the only person in the front of the vehicle. The front center airbag will be designed to work with other airbags to form a more complete vehicle occupant restraint...

Skiing and snowboarding are sports that I am fond of. Why not have googles that give you all kinds of statistics while you slide down the mountain? They will come with GPS and have a screen in the glasses. The display will tell you things like your contact information, external conditions, speed, altitude, distance, temperature and number of runs. You can even use them as a stopwatch and a clock to keep your progress.

My idea is to use piezoelectricity to generate energy. Piezoelectricity is the charge that accumulates in response to applied mechanical strain, such as the vibrations of vehicles driving on roads. The piezoelectric sensors are inexpensive and can be installed during regular repaving. When utilized on a single lane, two mile stretch of road, the sensors could produce up to 44 megawatts of electricity each year, which is enough to power 30,800 homes for a year.

A new solar powered communications module lets snow sports enthusiasts power their gadgets with the sun and control them with a Bluetooth enabled glove. The module includes speakers integrated into the helmet, a microphone in the chin strap, and a Bluetooth unit for sending and receiving data. To create the built in, curved solar panel solar cells are divided into small chips, allowing the cells to be spread over the arching surface and reducing chances of damage from stress. ...

A new technique using gold nanoparticles will make it easier to analyze old, dry fingerprints, possibly adding new evidence to cold cases. Why not develop a new method of targeting amino acids in sweat by combining antibodies that will bind to amino acids with gold nanoparticles. The antibodies will bind to the amino acids, and the gold nanoparticles will help to bring the details of the fingerprint into sharper focus.

Red wine has been proved to have certain medicinal properties as an active anticoagulant. Actually this fact was known in the ancient times. "Heart wine" was popular in medicine of that time.
