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.. |
|

"I only told you to blow the bloody leaves off !" |
|
| |
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. |
