Parachutes open under the water and connected to pipes to collect oil spills

Each parachute uses a configuration called disk-gap-band. It has 80 suspension lines, measures more than 50 meters (165 feet) in length, and opens to a diameter of nearly 16 meters (51 feet). Most of the orange and white fabric is nylon, though a small disk of heavier polyester is used near the vent in the apex of the canopy due to higher stresses there.

We add a textile goretex type pipe to each vent in the apex of each canopy, goretex to avoid gazes problems and to select them according to molecules sizes.

We can use as many parachutes as it is necessary to collect all pollutions, in a reverse cascade.

Most 80 suspension lines are fixed to anchors or concrete blocks around each leak.

Pioneer Aerospace, South Windsor, Conn., built the parachutes for testing and for flying on the Mars Science Laboratory.

Another huge parachute was formally installed on the re-entry capsule of Shenzhou-VI manned spaceship, ensuring its safe landing on earth.

The parachute was handmade, with 1,900 small pieces of cloth stitched together, and can endure maximum temperatures of 400 Degree Celsius. Its main parachute covers an area of 1,200 square meters.
