| Efficient wind turbines in cities 
Create a huge cone shaped Helium balloon with a big funnel like opening in the center. Now place a wind turbine in its center to generate electricity, tie this structure to ground and release it up at a very high altitude to get high-speed winds. Ropes should be tied in such a way that the concave side of the balloon faces the direction of coming wind.The Concave shape will trap more wind and will result in greater efficiency of turbine. At high altitude there is more wind (look at kites). No need of high (expensive) towers and can be easily placed in cities.Reward: Thank me at zyxRationalist@yahoo.com

| Soil Dam
We are worried about soil erosion filling our water dams with soil, leaving us with no more water in them and loss of rich soil from higher areas. So what if it is possible to build a dam or small dams near the place where soil erosion is taking place? It may stop the soil where it belongs and not fill our water dams.PS. If u happen to know any Dam Builders please inform them about this idea on this website. Reward: send bcc mail to everyone, ask them to goto creativitypool.com and search for "zyx", because more people know about it the greater are its chances of implementation.
