The next generation of mobile devices may be able to use their LCD screens to harvest a variety of light, including their own backlight, to be used as energy sources. The screens will be made up of polarizing organic photovoltaics which will be able to harvest energy from sunlight and ambient light, as well the device's backlight, and convert it into energy to power the device. The backlight of a device will use up to 90 percent of its power, and up to 75% of the light...

The idea is to introduce new polymer-based currency which is supposed to foil counterfeiters. The new bills will make it easier to recognize fakes, and they will last 2.5 times longer. They will feature a metallic portrait, transparent text, raised ink, a frosted maple leaf window, and hidden numbers. It will be possible to check the hidden numbers by holding the note up to a light, with no need for UV lighting.

My idea is to create a new billboard powered by an electrochemical reaction using the acid from oranges as the catalyst. The billboard will be lined with a gridwork of copper and zinc spikes that will keep the oranges in place while also reacting with the acid of the oranges to create the electrochemical reaction, essentially creating a huge battery of oranges.

My idea is to create a wireless keyboard that can be rolled up and packed away, providing tablet users the convenience and comfort of a keyboard. The keyboard will use Bluetooth technology to link with a tablet or mobile device from up to 30 feet away and, once paired with the device, won't need to be re-paired. The silicon keyboard will be water resistant, and will include a Li-ion battery, power switch, and a mini-USB charging port. LED indicators will relay the status and...

It was proved that the bacteria in a sheep's stomach that enable it to digest cellulose can also help clean TNT contaminated soil. The TNT breaks down completely, leaving no trace in the animal's feces. Why not plant grasses in TNT contaminated soil and set the sheep free to graze and clear the land at the same time. According to my estimations, a flock of 20 sheep could completely clear an acre of TNT residue in less than three years.

I'm really fond of the idea of creating a device that helps strengthen the connection between a swimmer's arms and legs, effectively making both of them more powerful. Worn in front of the body, it can be used to generate resistance so the wearer uses more muscle power with each stroke. Worn running down the spine, it helps maintain correct posture.

I have the idea which could help to increase crop yield by 10-20 percent. Why not develop a liquid foam shading system that mimics cloud cover? Such a system will make it possible to automatically shade greenhouses. This foam will filter the sunlight (i.e. will reduce solar radiation and control temperature) while still providing the plants with the light needed for photosynthesis. There also will be sensors to monitor the conditions within the greenhouse.

Oil lamps are still widely used in spite of the fact that they are toxic and not environmentally safe. My idea is to use solar lamps instead of oil lamps. Solar lamps work 6 hours and above; they are available for all people who don't have reliable source of electricity. Solar lamps have changeable solar batteries which are environment-friendly as they are recyclable. Lamps have brightness regulator, they are water- and heat-resistant and can even be used below -4 °F and above 131°F.

Below are a couple of tips which can help you to get rid of bad garlic breath: 1. Parsley and other herbs. Due to the high level of chlorophyll found in parsley, it actually works very well as a breath freshener. If you happen to have other herbs and spices around, you can also try chewing on mint, cardamom, cloves, or fennel. 2. Lemon. Even more readily available than parsley is lemon. One of the easiest ways to make use of this garlic breath remedy is to simply drink...

Tornado can often strike at night when people are asleep and not tuned into the weather channel. As a result many of them are injured or killed. My solution is to create software that the National Weather Service can use to inform people about the tornado (in a single second). It will send text messages to all cell phones/landlines to people in areas most likely to be hit. This will be definitely a great warning system for those who are not tuned into TV, but are carrying phones.
