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.

Why not use sunlight and ethanol to create hydrogen at ambient temperature and pressure? This could make production less expensive while delivering higher yields. The process will involve mixing a powdered form of a photocatalyst and ethanol in a container and then agitating the substances while they are exposed to ultraviolet light. A semiconductor inside the container will generate electrons, which will be captured by gold nanoparticles in the catalyst and react with the alcohol...

The paper thin, mercury free OLED lights will be the most energy efficient kitchen lights. It is difficult to perfect white lights that are powerful enough to be suitable for kitchen use, but the OLED lights are supposed to be as bright as the typical compact fluorescent. They will also be incredibly thin and have a life span of more than 12,000 hours. The system efficiency of 71 lumens per watt will be greater than the standard requirement for undercabinet lighting, and the lights...

The idea is to create solar window shade that will harvest the sun during the day and use it to power its OLEDs at night. The shades will be made of a semi-translucent, flexible fabric that will allow the sunlight to gently seep in. The integrated solar cells will block the sun while harnessing its energy, which will power the leaf-shaped OLED's. A central cord will control the blind, allowing it to be opened, and the whole shade can be easily rolled up for storage.

Technologies are constantly developing and becoming cheaper. They make our life more comfortable and joyful. A virtual window in a wall is a great example of such development. It can display any dynamic pictures you like: from the magnificent scenery to the life in the deep sea or the view from the orbital station window. Winscape virtual window provides the effect of presence in front of the real window. The view from the window changes depending on the position of the...

Static electricity occurs as a result of charges difference (negative and positive) between two objects. Sparks, which occur during discharge, cause irritable effect on the human body. How to minimize this affect? Below are several static control methods. * Increase the humidity of your home. You can do this with a humidifier. The humidifier will add moisture to the air. This moisture will make the air more conductive, which will decrease the ability of things in your home to...

The newly improved radiator booster will increase the efficiency of wall mounted radiators, directing the heat back out into the room. The booster will be designed to turn on when the radiator reaches a temperature over 86F, and it will cost under a dollar a year to run. Since it will distribute the heat out into the room, the radiator booster should help to encourage lower thermostat settings.

The new light alarm clock will make getting out of bed just a little bit easier, gently increasing the light for a more natural alarm. The light is meant to simulate the natural sunrise, slowly increasing its glow over a period of 30 minutes, and can be programmed to include chirping birds or music. It will also dim slowly, easing the user into natural sleep.

A self cleaning cloth will be able to destroy bacteria and toxins when exposed to light, which could be used to make safer clothing for farmers and medical workers. The cloth could be developed by incorporating the unusual compound 2-anthraquinone carboxylic acid (2-AQC) into the fabric. The compound will bond to the cotton without changing its properties, and produce hydroxyl radicals and hydrogen peroxide when exposed to light, which instantly will kill bacteria and break down...

If you are tired of the same old boring wallpaper designs on your wall then you'll find my idea interesting. I suggest creating digital wallpaper. There would be digital paper or some kind of very thin screen on your wall. A small computer box would also be on the wall. You would be able to download any image you wanted to see on your walls. In such a way you could change wallpaper every day.
