| Hydraulic car 
I am not an engineer but it seems to me that a light car should be able to be propelled for short trips by human power. I suggest a bicycle drive connected to a hydraulic pump that in turn feeds an orbit motor or perhaps directly to an automatic transmission. I suggest hydraulic power rather than mechanical drive because a relatively small hydraulic pump can produce tremendous pressure. Heat from the oil flow could be cooled through the existing oil cooler or directed to an interior heater for cold climates. It likely could not develop highway speeds but most urban traffic now flows at less than 60km/hour. For longer trips perhaps it could be supplemented with a small gasoline engine similar to those used on bicycles occasionally. I welcome advice or suggestions.

| Pollution Vacuum
We've invented vacuums for dirt on the ground, why not for our air? We have the technology to compress oxygen, why not our pollution? I doubt there is any use for the brown cloud of dirt that lingers on top of cities, so my idea is to suck it up like you would oxygen and either store the containers some where, or launch them into space on the next expedition.As another, very expensive and expansive idea, we can create a huge (I don't use that word lightly) funnel-like tube, resistant to the atmosphere. This tube can penetrate the atmosphere and suck up all the burdening gases (and maybe everything else with it). It's a very dangerous idea, and I've no idea of the physics.Reward: Recognition.

| Magnetic Bumper
My idea is to insert magnets into the bumpers (front, back, side and rear) of cars. This, if developed properly, could prevent all vehicular accidents. I'm not sure if it's feasible, but I really want to know about the possibilities. Any information would be great.Reward: Credit for the idea and maybe a development role would be fantastic. Let me know me know about the possibilities.
