| Wind energy pollution removers 
Wind turbines are being used to generate electricity in several countries (Denmark for example). Why don't they have turbines that exist to remove polluting particles from the air and perhaps transfer them to the base of the station. If some of the emissions of automobiles could be captured by a "windmill" then instead of using the power to generate electricity it could be used to gather the particles and concentrate them into something that is no longer floating in the air, but contained in a solid lump. Since the air cleaners are run by wind energy, there are no electricity costs to run them. Reward: I hate air pollution. So if you can invent this, you would make me happy. That would be my reward.

| Extraterrestrial Trash Dump
We all know that if the amount of trash on planet earth keeps increasing at the current rate, we won't have any place for it! And there is that useless moon floating around earth way up there in space. So why not send our trash up there to be buried on the moon? A little strange I know, but it could be a possibility. And I'm not sure exactly how all this would happen, like if the garbage would stay underground or not. But it has potential, don't you think?? Please take the time to reply to this!! I would appreciate it a lot!Reward: Ummmm... I could live with the Nobel Peace Prize!! LoL!!

| 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
