The air purifier bike concept will let riders clean the air as they ride by filtering out pollutants and creating oxygen. The concept bike will be equipped with an air filter between the handle bars that will screen pollutants and dust and an oxygen-producing "photosynthesis system" that will include a water tank, electric motor and a battery. As the bike is being ridden, air will be forced through the filter and cleaned, allowing fresh air to flow onto the cyclist. The...

A new CO2 scrubbing filter inspired by bird lungs could be applied to both power plants and automobiles. The scrubber will be based on the tiny tubes inside the lungs of birds, called parabronchii. The tubes, with their large surface area, are very efficient at filtering oxygen from the air--a necessary adaptation since birds fly often fly at altitudes where there is very little oxygen. Using the lungs as a model, it will be possible to design filters made of different-sized...

Portable air quality sensors could help people suffering from chronic conditions like asthma and COPD breathe a bit easier by allowing them to check the air condition in their immediate with their smartphones. The system will consist of small air quality sensors that could be carried by the individual or deployed around a particular area. The sensors will be able to measure local concentrations of pollutants, such as carbon monoxide and ozone, and transmit the data wirelessly to...

The Robo-Fish is designed for constant monitoring of marine pollution, detecting sources of contamination and relaying the information back to shore for real-time updates. The 1.5 meter device is based upon the hydro-dynamic shape and motions of an actual fish, which allows it to maneuver quickly and easily, even in weedy areas. It can detect contaminants with an array of micro-sensors, and, since it is constantly monitoring the area, send an alert immediately if it detects...

The new "smog eating" panels will be designed to be attached to the exterior walls of a building, where they will absorb pollutants from the air. The panels will be coated with titanium dioxide, which will break down pollutants into harmless matter when exposed to direct sunlight. The matter will then be washed away at the next rainfall. 10,000 square feet of panels are supposed to clean the same amount of air as about 80 trees.

It was proved that the bacteria in a sheep's stomach that enable it to digest cellulose can also help clean TNT contaminated soil. The TNT breaks down completely, leaving no trace in the animal's feces. Why not plant grasses in TNT contaminated soil and set the sheep free to graze and clear the land at the same time. According to my estimations, a flock of 20 sheep could completely clear an acre of TNT residue in less than three years.

It would be cool to have ear plugs able to filter noise electronically. Using such ear plugs, you can easily talk to a co-worker, while filtering out background noise, by simply twisting the adjustment knob.
