Why not develop wearable solar and thermoelectric power systems for soldiers to reduce the loads they typically carry? My idea is to use solar cells to generate power during the day, while at night thermoelectric devices would harness the difference in temperature between body heat and night air. The systems could be woven into the soldiers' uniforms, and the electricity stored an advanced form of storage device.

Why not create a solar handbag able to generate enough power to charge a mobile phone and still will look fashionable? The bag's outer layer will be made up of 100 small silicon solar cells that will be arranged in a decorative pattern. Conductive embroidery woven into the surface will deliver the harnessed solar energy to a lithium-ion battery within the purse. The solar cells will have an efficiency of 9% and will be able to generate two watts, even without much daily sunlight...

Do you still use rake to pick up leaves in your yard? I suggest a new idea how to make your yard clean easily. What about a vacuum with a bag attached which you can place on your back? It could look like an industrial blower but it would pick the leaves up instead of blow them away. It could have either electrical or gas engine. Such a vacuum will definitely save time and make the yard work a little easier.

The idea is to create a microchip to block delivery of pain messages to the brain. The chip will be imbedded in the body between the source of pain and the brain. It will be wired to a larger implanted device which will contain a battery and a computer processor. If the chip detects a pain signal headed to the brain, it will send out small 10-volt pulse to block the signal and relieve the user of the pain.

I want to create a mobile phone application for those who don't want to waste time standing in line. One will have a possibility to check as well post line conditions with the app running on a mobile phone.

A newly developed technology allows users to charge their cell phones by yelling at them! The technology works by transforming sound waves into power in a similar way that speakers transform electric signals into sound. Currently, the device consists of a sound absorbing pad that creates vibrations when hit by sound waves. The pad is connected to zinc oxide wires that compress and release, which creates a current and generates the battery.

The idea is to develop an animated sign language translation system that will automatically convert words into gestures for deaf viewers, which could help improve the spread of information during disasters. Subtitles are not always enough for people who use sign language as their main form of communication. The new system will be able to convert the text into sign language delivered by a suit-wearing avatar in a virtual newsroom. The system will also able to use synonyms to replace...

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 with that artificial rainbow is fantastic. A rainbow machine has been already created. It uses reclaimed rainwater and sunlight to create rainbow effect. The machine applies jet pumps and custom fountain nozzles to spray water in the air, and then the sunlight shines through to create the rainbow effect.

The idea is to create a new ring mouse. It will be worn on the hand and controlled by the thumb, using a new optical touch technology. The Ring mouse will weigh less than half an ounce and will have a wireless range of about 30 feet. The ring will be worn on the index finger, with the left and right click and touch control tracking arranged around the top of the ring and controlled by the thumb. Primarily intended for presentation controls, the new mouse will also be useful...
