THE PORTER SCHOOL OF ENVIRONMENTAL STUDIES (PSES) at Tel Aviv University - Israel To excel as a multidisciplinary research & educational entity. To promote environmental awareness & shape policy in cooperation with research institutes, government, industry, and environmental NGOs.

From bios, meaning life, and mimesis, meaning to imitate. Biomimicry From bios, meaning life, and mimesis, meaning to imitate. A new discipline that studies nature’s best ideas and then imitates these designs and processes to solve human problems.

Termite-Inspired Air Conditioning Eastgate (Harare, Zimbabwe) uses only 10 percent of the energy of a conventional building its size, saved 3.5 million in air conditioning costs in five years, and has rents that are 20% lower than a newer building next door.

Abalone Inspires Lightweight Building Materials The shell of the Abalone is a remarkable ceramic that is twice as tough as our high-tech ceramics. Mother-of-pearl is composed of alternating layers of calcium carbonate and protein. The combination of hard and elastic layers gives nacre remarkable toughness and strength.

Tests showed that this technology reduces energy requirements. Nautilus inspired fan A three-dimensional spiral is found in the shells of Nautilus. Flow through these geometrically consistent forms with far less friction and more efficiency. PAX Scientific has designed propellers, impellers, and aerators based on this shape. Tests showed that this technology reduces energy requirements.

Drugs (gifts) from the Sea Yondelis® is a marine derived antitumoral agent discovered in the colonial tunicate Ecteinascidia turbinata and now produced synthetically. Yondelis binds to the minor groove of DNA interfering with cell division and genetic transcription processes. Yondelis® is currently being developed by PharmaMar in partnership with J & J

Researchers at the U.C. Berkeley developed microfibers, inspired by the gravity-defying gecko, that can keep objects from sliding down near-vertical surfaces.

DaimlerChrysler engineers mimicked the musculature and cube shape of the fish to develop a car that is aerodynamic, with a protective outer core. The concept car improves the drag coefficient of today's compact cars by more than 65 percent.

Giant algae (kelps) as biowave Biopower Systems is developing a so-called wave energy conversion system, or biowave. It modeled its device on the motion of kelp.

The design for the Japanese Shinkansen bullet train is based on the beak of the kingfisher bird.

The lotus plant could ball up rainwater and pearl off dirt from its surface, leaving it clean and dry . German company draws on the Lotus Effect to make its facade paint. When the paint dries, it is highly water & dirt repellent, keeping buildings cleaner.

Biofouling Hydrodynamics - negatively affected, increased fuel consumption, degradation of ship performance, frequent docking, spread of invasive species The University of Bremen has created an artificial sharkskin that mimics natural sharkskin's innate resistance to biofouling.
