Seascraper

A seascraper is a megastructure that is a floating city with a green design. It would generate its own energy through wave, wind, current, solar, etc. and produce its own food through farming, aquaculture, hydroponics, etc.

It will consist of homes, commercial space, recreation areas, etc. and will be located where deep sea current is adequate for the production of power. Tethered to the hull, turbines will reach to depths beyond 800ft and harvest ocean currents.

A seascraper called SEAWER is designed to collect plastic from the Great Pacific Garbage Patch (GPGP) and has the following features:


 * Hydroelectric power plant generating power 24 x 7.
 * Five layers of baleen filters for plastic collection, and plastic recycling and granule manufacturing
 * purification for contaminated seawater
