Powerless Leaf Blower

use one large foam wing to blow leaves off cement
  [vote for,

This is a giant foam wing that gardeners can wear on one arm, and swing through the air in a figure 8 blowing leaves off surfaces like cement.

This will save on the noise that leaf blowers make and will save on gas and the environment.

       //blowing leaves off surfaces like cement.   

       Is that using air to blow leaves off hard surfaces, or is that using air to blow cement off surfaces?   

       //one large foam wing...will save on gas and the environment.   

       Borderline, from the polystyrene wikipedia "In expanded polystyrene, these are usually hydrocarbons such as pentane,..Extruded polystyrene is usually made with hydrofluorocarbons (HFC-134a),which have global warming potentials of approximately 1000–1300 times that of carbon dioxide."   

       Then there's the recycling..."Most polystyrene products are currently not recycled due to the lack of incentive to invest in the compactors and logistical systems required".   

       As for disposal "When polystyrene was burned at temperatures of 800–900 °C ... "a complex mixture of polycyclic aromatic hydrocarbons (PAHs) from alkyl benzenes to benzoperylene. Over 90 different compounds were identified in combustion effluents from polystyrene."   

       Now, if you were talking about balsa wood..

       Human power does not equal "powerless".

       //Don't use expanded polystyrene, then.   

       What, and use compressed polystyrene? Any passing prankster* could expand the wing to A380 size.   

       *with a lot of equipment, pentane and a great deal of patience.

       Wouldn't a circle be more efficient?

       // expand the wing to A380 size //   

       This is, in fact, exactly how the wings of the 787 are produced ....   

       Not a lot of people know that.
