GOOD NEWS IDEAS #103 - #107
#103 - Dandelion Rubber?
Most of us think of dandelions as yellow weeds. But it turns out one Russian variety may be able to produce rubber as part of its growth cycle. If this turns out to be successful, it could be planted twice a year in good climates and be more productive than the rubber trees that presently provide natural rubber. Because it is a weed, it is tough and resilient. The trick will be to adjust its DNA to produce significant amounts of the rubber. Research is going on both in Germany and in America.

#104 - Nuclear Waste Storage
Just as interest is heating up again for nuclear fission power reactors, so is the ongoing question of where to store the waste. Sandia National Laboratory has a new answer that is surprisingly simple--drill very deep boreholes and bury the waste two kilometers deep (about 1.2 miles) in hard, crystalline basement rock which is available in most of the United States. This means no long distance transportation and a wide dispersal of the waste materials. Why didn't we do this 25 years ago? We didn't have the drilling technology to go this deep. If this solution works out, it lowers the cost of storage as it makes it much safer.

Drilling Deep Under the US to Dispose of Nuclear Wasteby Phil McKenna
A Texas company named MileMeter is proposing a new way to purchase your insurance--based on the miles you drive. In a sense, you get what you need and no more. And, also, low mileage drivers aren't underwriting high mileage drivers. This idea is very interesting to me because it is also a potential model for how road taxes might be raised for electric cars, many of which will never need a single gallon of gas. Brookings Institute did research on this kind of insurance and found that it will probably lower driving miles by about 8% if it were adopted.

#106 - French Cars
Electric Motors in Each Wheel
Even as the first electric cars are rolling out (think Nissan's Leaf), new design ideas are flourishing. One area of focus is where to put the electric motor or motors. Michelin tire company is the leader in the concept of an "active wheel" in which both the electric motor and the suspension are located inside the wheel. That would mean four wheel drive and no need for a special place to put the motor which means more room for storage space and batteries. It looks like the French have done it again. By the way, be sure to watch the video at the site. It is very impressive!
#107 - Cleaning Water Cheaply
The present paradigm for cleaning water is to use a lot of complex expensive equipment to do it. But maybe not in the future. Research done on the cactus plant indicates that these plants have a very efficient way of removing both pollutants and bacteria from dirty water. Norma Alcantar at the University of South Florida and her team looked into the way the prickly pear cactus gets its water. They found that its "mucilage", a kind of gum it uses to store water, causes the impurities to clump together and settle out. The researchers will now look at the best way to apply this technology cheaply.
