Contemporary light bulbs may soon be replaced with flexible sheets of glowing LEDS. The LED sheets will be produced by slicing a gallium nitride wafer to create millions of tiny LEDs. The LEDs will be mixed with binders and resins to form a sort of 'ink', which will be then deposited over a large surface using a standard screen printer. A layer of silver ink will provide electrical contact and a layer of phosphors will be used to change the color of the LED light. The LED...

Why not develop lightweight and translucent curtains able to absorb sound more effectively than conventional curtains, while also allowing the sun to shine through?

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.

I want my house to repel heat in summer and absorb heat in winter. My idea is to create paint (or vinyl siding) that becomes darker when it is cold and lighter when it is warm. With such paint I would accomplish my goal.

The idea is to create a new LED bulb able to be controlled by any Android device. It will set the precedent for a new generation of energy efficient home systems. The bulb will include a built in radio to interface with Google's open source wireless protocol. Besides the bulbs, the protocol will also be used to control thermostats and appliances, leading to a new type of self-adjusting systems.

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.

It would be really great to have sound filters for windows. They could work much like the mosquito nets. In case you fastened such a filter on the outside of your window it'd keep out all the street noise, but would let in the fresh air.

The idea is to create a USB charging device that will flip open to draw power from electrical outlets already fully occupied. The device will open to extend a flat conductive "power tab", which will work via its two holes. The prongs of one of the plugs that will be occupying the outlet will be run through the holes and then plugged back into the outlet. The power tab will draw enough energy to charge a mobile device, sending 1 amp through the USB cable. A flat "power tab"...

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.

The idea is to develop a water reclamation system that will recycle bathroom sink water to use for flushing the toilet, which could save up to 6000 gallons of water each year. The system will consist of a box under the sink that can hold up to 5.5 gallons of used sink water and a pump which will transfer the grey water to the toilet's water supply. Such a system is supposed to save up to 65% of potable water per flush.
