Can Pigeons Poop Soap?

Happy Tuesday,
I came across this article while browsing one of my favorite sites, www.treehugger.com, and thought I would share...

Pigeon d'Or

Run Down:
     Basically, this designer-turned-scientist, Tuur Van Balen, came up with the idea of altering a pigeon's diet so that the pigeon defecates a soapy substance. Theoretically, a specifically developed bacteria added to the diets of pigeons could do this, turning the pest into a "free flying cleaner." His plan was to "1. make pigeons poop soap" and "2. build specially designed coops to house the pigeons where they can be fed, and direct their feces onto car windshields."

Details:
     Amazingly, Balen managed to score a grant to fund his project, yet ethical dilemmas are arising. Will the intention of cleaning up our cities (and windshields!) overpower the animal rights activists? Only time will tell...
