The idea is to develop carbon-negative bricks made from coal and sewage waste, materials that normally end up in landfills. To make the bricks, the recovered waste material will be mixed with vegetable oil containing glyceride and triglyceride molecules. The bricks will then be heated to break up the glycerides and attach them to the triglycerides, which will form chains of carbon atoms that will surround the particles and bond them to the brick. The manufacturing of the new...

charge a electric car in the highway and city with the car is running at the same time it a very good idea and i can make it easy to work if you can charge a car when is going down tyhe highway person can buy and charge a electric car in the city or at home too

The idea is to create a backpack mounted rainwater catchment systems that will be portable enough to harvest and clean rainwater, as the weather permits. The rainwater catchment and filtration system will be built using off the shelf components from a standard store. An expandable bag will collect and hold the water, while the built in filtration layers will render it clean enough to drink. It will be worn on the back or stand alone, and will also be used in conjunction with...

The Scrubba wash bag is a portable washing machine, weighing just over 6 ounces and able to wash several items of clothing at once. The Scrubba is basically a washboard in a bag. To use the Scrubba, the bag is filled with about 3 liters of water and 3 drops of soap per wash, sealed, and the extra air expelled through a tube. The washbag is then placed on a table or the floor and compressed and rubbed for about a minute, which scrubs the clothes with the interior washboard. Clothes...

A new helmet technology inspired by the brain's natural cerebrospinal fluid allows the head to 'float' inside the helmet, which reduces the forces of an impact. The technology is designed for falls when the head hits the ground at an angle. The helmet contains a low-friction layer between the inner liner and outer shell, which allows the liner and shell to move in relationship to each other and limit the impact.

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 ballistic clipboard will be able to stop bullets and protect against knives while still keeping the papers tidy. Designed with the police force in mind, the ballistic clipboard will provide "multi-hit protection" from a range of ammunition types and weigh under 2 pounds. The device is meant as an additional precaution, and will provide protection against assaults during traffic stops.

The idea is to create a wheelchair that will be propelled by the user pushing and pulling on a center mounted lever. Such a chair will offer a better mechanical advantage while also reducing the chances of repetitive strain injuries. It will be steered by turning the center propulsion lever to the left or right, and brake levers mounted on the handlebar will control the dual disc brakes. There will be eight gears available, and the chair will still be maneuvered by the traditional...

The idea is to create a raincoat that will not only protect the wearer from the rain but also purify the water with charcoal and chemical filters. The water filters and storage containers will be hidden in the coat while the tubes will be left visible to enhance the aesthetics. The collar of the raincoat will collect the rainwater, which will then be passed through the filters at the back of the coat and stored in the hip.

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...
