Why not create an automatic streetlight which will be able to switch off and on as cars go by, potentially saving energy and reducing costs? The streetlight will consist of an automatic lighting system, PC, lamp, and camera able to capture an image of any passing car. The image will be processed by the computer, which then will instruct the light to switch on.

Why not create bomb sniffing plants? They will be able to screen the air and provide a warning system for dangerous substances such as explosives. Plant proteins will react to airborne pollutants or trace chemicals from explosives with visible responses, such as blanching white.

I have one more idea of creating a new streetlight system in order to save money and reduce energy waste. The system will use motion sensors to dim its lights to 20 percent power when no moving vehicles or people are nearby. The system will reportedly cut energy consumption and CO2 emissions by up to 80 percent. The streetlights will use LED bulbs that will be wirelessly linked. This will allow the lights to create a 'pool of light' that will follow the pedestrians and eliminate...

The idea is to develop a new sensor integrated steering wheel able to provide a quick vital sign check for the driver and easy to integrate into mass produced vehicles. While there have been many new systems for monitoring stresses while driving, most of them are too complex for commercial use. The simpler steering wheel system will be able to monitor blood pressure and stress levels through reflected light and electric conductance. The driver will need only have his hands on the...

The idea is to create a fingerprint scanner able to tell the difference between living and dead tissue, preventing the use of a severed digit being used to foil fingerprint scanning devices. Fingerprint scanner able to identify dead tissue The scanner will work by reading the difference in the amount of light absorbed by living tissue versus dead tissue. The amount of light absorbed by a living finger will vary, changing from 550 nanometers when it is first placed on the sensor...

A new device will be able to analyze the sweat in a person's fingerprints and determine the substances in their body. The device will be small and quick, with the entire analyzing process taking only a few minutes, and will be powered by safe and disposable cartridges. The results will be linked to a record of the user's fingerprints, so the results will be difficult to dispute.

The idea is to equip cars with the airbag system for pedestrians to reduce the force of an impact on people outside the car. The airbag will be contained beneath the hood just next to the windshield, and will automatically deploy if the sensors in the front bumper detect contact between the car and a person. The system will work in conjunction with the Pedestrian Detection technology, which will detect if a person walks in front of the car and will automatically activate the brakes...

Isn't it great to have a temporary refuge that allows visitors to enjoy the wilderness while preserving the pristine environment? The self-supporting solar powered cabin will designed to be transported by helicopter to the desired area and set up on pipe piers, with minimal impact to the site. The water will be delivered by snow melted by the solar system; appliances will be powered by the solar electric system. There will be a supply of bioethanol available for emergency needs,...

The new forearm crutches will be made to stand up to rigorous use, featuring an internal shock absorber and more comfortable arm and hand supports. The most unique feature of the crutches will be the rotating, articulating feet which will allow the foot of each crutch to lay flat against the ground during the entire stride, lessening the torque in shoulder joints. The feet will be available in a variety of styles, including snowshoe and sandshoe, complete with an ice pick and a...

The idea is to create a new invisible vapor coating which will protect electronic devices from water damage. The coating will be a "nano-scale film barrier" that will cover all the interior spaces of a device. Since the product will work at the nanoscale level it will be virtually invisible, and will not distort displays or affect the user's tactile experience.
