Old CD's can be put to a new use and turned into dumbbells, providing an incentive to workout while also reducing waste. The dumbbell kit will consist of a handle and two sets of dumbbell caps. The discs will slip onto a spool running through the center and attached to the handle, and the caps will close to keep them secure. Discs can be added up to a maximum weight of 5 pounds, including the 2.2 pound handle.

Wine bottles made from a paper based glass will cost less to produce than conventional glass and will have only 10 percent the carbon footprint. The paper wine bottles will weigh only 50 grams, instead of the 500 grams of a standard wine bottle. Its shape and dimensions will be the same, however, so it can be easily integrated into existing displays. The wine itself will be contained within a foil bladder similar to a wine box. The paper wine bottles could be useful for...

The Sunflower is the first heliostat created for residential use, designed to allow homeowners to focus the sun into a gloomy room on onto a solar panel.

It can redirect up to 50,000 lumens of sunlight and can be installed on an existing post or optional PVC stand. Beyond feeding solar panels and dark rooms, other...

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...

The idea is to develop a method of spinning starch in fibers, which will lead to inexpensive paper products and biodegradable bandages. Starch is the cheapest and most abundant of the polymers, but becomes a thick paste when it contacts water. To counteract this effect, it is possible to add a solvent to the starch to enable it to be dissolved in a fluid without losing its molecular structure. An electrospinning device will overcome surface tension and allow the starch to be...

A designer from India invented a unique jeans design, which helps to protect wallets from pickpockets. The main feature of these jeans is that there is a copper wire in their seams. The wire is connected to a special device consisting of capacitors, a 3-volt battery and a magnetic switch. This electric device is placed in a case and can be activated by the user at any time. Its mechanism of action is simple - once a thief feels about for the wallet in your pocket, he is...

I am thinking of creating some fish saving device. It can be an aquarium which records the water temperature, ph level, oxygen level, amount of food eaten etc. and automatically fixes the problem by adding food and/or by adding oxygen or heating the water according to the settings defined.

I'm a soccer player. It is a real disaster for me to have a game on a sunny day as I hardly see anything and often lose the ball. My idea is to create sunglasses that are contacts so as I could look into the sun and see the ball.

I want my house to repel heat in summer and absorb heat in winter. My idea is to create paint (or vinyl siding) that becomes darker when it is cold and lighter when it is warm. With such paint I would accomplish my goal.
