The idea is to place timers on the doors of individual toilet cubicles. This will let people know how long it is since someone else last used the cubicle and see which one has been vacated and "aired" for the longest time.

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.

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.

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

Why not create a thermostat that will keep track of each time the home owner adjusts the temperature, eventually setting itself to the most favored temperatures. The thermostat's heating and cooling cycles will be set by a single wheel, and it will also be controlled from a distance by smartphone. In addition to learning the owner's preferences, its integrated sensors will also keep track of light, humidity, motion, and light. The thermostat will automatically adjust itself...

A newly developed liquid in conjunction with bacteria-killing gas will use viruses to help break down the resistance of antibiotic resistant bacteria, rendering them vulnerable to conventional cleaning products. The liquid will take advantage of virus infecting bacteria called bacteriophages. The bacteriophages have been engineered to restore a gene in the bacteria that they have lost in the process of becoming resistant. The liquid should cost only a few dollars per liter.

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.

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...

The benefits of sun exposure have been known for a long time. Sunlight is involved in reactions of insulin synthesis, it maintains a balance of skin microflora, vitamin D and serotonin (the so-called hormone of happiness, which controls appetite, sleep, mood and emotions) are produced under ultraviolet light. But the sun is a medication that should be taken strictly in graduated way. Doctors of all the countries are sounding the alarm and warning people about the harmful effects of...

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"...
