Argentinian-born artist Cesar Saez is building a giant banana, to be filled with helium and floated in a geostationary orbit over Texas:
Basically, the banana will be constructed like a blimp. Filled with helium, it will float between 30 and 50 km up in the sky. It will have a semi-rigid structure made of bamboo and a skin made with synthetic paper. Thanks to extra load in gas and a valve system, it will keep its shape at all times. The final size of the piece will be 300 meters in length. The expected launching date is August 2008 from around Baja or Sonora, north-west of Mexico. The total costs for this project is roughly estimated at one million dollars.
