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.

An inflatable plug designed to prevent terrorist attacks could be used to help keep tunnels and subways from flooding. The flood-stopping plugs will be made using some of the same materials and processes that are used to make space suits. The plug will consist of three layers, which will help it maintain pressure, and will have a circumference slightly larger than the tunnel entrance, which will ensure a tight seal. It can be inflated using either air or water.

I suggest using a plastic metamaterial to build a cloak that makes objects invisible to sound waves. The cloaking device will be made of stacked sheets of plastic filled with holes that will be sized and arranged to redirect sound waves by either blocking them or absorbing them. The device will work for audible frequencies between one and four kilohertz, which is the same frequency as the higher two octaves on a piano.

So, this is for all the modern, edgy, punk youth out there. Or possibly weird, zany, old people. Basically, it's just coloring highlighter on your eyelids as eyeshadow. It's very cool. It brings out the color of your eye with he contrast. I tried it on my friend, and the only advise I can give you, if you try it, is to avoid rubbing it in your eyes! If I were to ever make this idea into something, I would start by calling it EyeLighter. Get it, the play on words... Anyway, then of...

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...

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 organic laser uses a protein found in jellyfish as its light source, creating the first organic laser. The laser uses a single cell as its optical gain media. The cell was engineered based upon a species of jellyfish that uses green fluorescent protein (GFP) to create bioluminescent light. An inch long cylinder with mirrors at each end was built, and then a cell that express GFP at the required level was placed inside the cylinder. The cell based device created short bursts of...

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...
