Driving down highways, you will see a lot of litter. Much of it is fast food packaging or other disposable paper. Education does not seem to be the answer, as we have been told not to litter for years - yet, it still piles up. More meals are being eaten on the road or sidewalk, as our lives become faster. What I believe we need is a paper that degrades quickly when exposed to the sun's UV rays. It would seem that the addition of titanium dioxide in its anatase form to the pulp would...

Current wind turbines are EACH equipped with a generator and a gearbox. We know large generators (such as used in electricity power plants) are more efficient, would it make sense to connect an array of wind mills via driveshaft to one large generator on the ground. Advantages: 1) high(er) efficiency generator 2) use only one big generator, not many small ones 3) big generator on the ground is easy to maintain (no climbing in towers) 4) individual wind mills can be cheaper...

This would be a good project for an Environmental Science/ Education Student. The physical object is quite simple, but the institution of the system would require much research and involvement. The actuall object: A backpack that holds a 32oz thermal mug, a set of flatware, and a lenin napkin. The hard part: One would need to do a cost analysis comparison between cost of waste removal and landfill use to the cost of distributing such a kit to all citizens of any given urban area....

In an effort to re-use the million of tons of building rubble produced each year, a way to recycle concrete with lightning was found. The lightning bolts of a short duration are more likely to pass through a solid. The idea is to produce lightning bolts and direct them to the concrete. As the lightning follows the path of least resistance, it separates the material into its fundamental components. A concrete recycling plant using the lightning method could be a reality in as...
