 Floating wave energy extractor.

* Anchored to the sea bottom.
* A new method for tapping offshore wave energy.
* Ideal for high wave offshore.
* Ideal for distant offshore.
* Electrolysing of sea water to generate hydrogen.
* As the system is anchored, it can be installed anywhere in the offshore(far distant offshore).

S.D.E. Energy Ltd. is a Tel Aviv, Israel manufacturer and marketer of Sea Wave Power Plants - utilizing sea wave energy to produce electricity economically, and in an environmentally-friendly manner claiming that their system can generate electricity for 2 cents per kWh.

Basically, the buoys are placed on a breakwater and they move up and down, according to the frequency of sea waves. The buoys' movement press a hydraulic liquid, which is regulated by systems that convert the energy to circular systems that operate an electric generator.

The buoys, which make 10% of the system, are placed in the water, and the rest of the whole system, which makes 90%, is set on land with the option being located on up to 500 meters from sea shore. In the event of storms, the system is easily accessible for technical service. Additionlly, the buoys are neutralized and laid down on the jetty or the shore.

The Syphon Wave Generator

【出展リンク】：　http://www.youtube.com/watch?v=asbn_Z_OWvI

The Syphon Wave Generator will convert ocean waves into electricity. It works like a hydroelectric plant with ocean waves dropping water from the top of the waves, through a turbine generator, to the bottom of the wave. It will convert renewable solar energy into electricity.

Wave Energy Device

【出展リンク】：　http://www.youtube.com/watch?v=tt_lqFyc6Co

http://waveenergy.nualgi.com/

It is a floating device tethered with chains to piles driven to ocean bottom. The wave action raises the heavy partially buoyant piston that drives the overhead crankshaft by half turn. The receding wave drops the piston completing the balance half turn. One revolution is obtained for every wave. Using gear box and generator the current is produced continuously.

Researcher Creates Strongest Metal Foam Ever

by Bridgette Meinhold, 02/01/10

Spongy metal sounds like a bit of an oxymoron, but it’s actually a real material that is capable of absorbing large impacts without damage. Metal foams have been around for some time, but new research by Dr. Afsaneh Rabiei of North Carolina State University, has revealed the strongest metal foam ever. It can compress up to 80% of its original size under loading and still retain its original shape. The applications for this type of material are too numerous to fathom, but one of the most anticipated uses for the spongy metal is in automobiles to lessen the impact of crashes and protect the driver and passengers.

Metal foam is exactly what you might think – a cellular structure made from metal with tiny pockets of space inside. What makes Rabiei’s metal foam better than others is that she’s been able to make the tiny pockets of space more uniform. And that apparently is what gives it the strength as well as elasticity it needs in order to compress as much as it does without deformation. Many tests are being performed in the laboratory to determine its strength, but so far Rabiei says that the spongy material has “a much higher strength-to-density ratio than any metal foam that has ever been reported.”

Calculations also predict that in car accidents, when two pieces of her composite metal foam are inserted “behind the bumper of a car traveling at 28 mph, the impact would feel the same to passengers as an impact traveling at only 5 mph.” Applications for this amazing material are numerous and life changing. Naturally, this metal foam could be integrated into the bodies of cars to minimize the impact from crashes, but it could also be used for body armor or even in artificial limbs. It’s even foreseeable that the metal foam could be used in buildings and help absorb shocks from earthquakes.

発泡金属は多くの空洞を含むスポンジのような形状をしており、これ自体は新しいものではない。しかしAfsaneh Rabiei博士率いる研究チームが開発した素材は従来のものより空洞の大きさが均質であるため強度及び弾力性に優れており、形を保ったまま元の大きさの8割にまで圧縮することも可能という。

Rabiei博士曰く、新素材は従来のものと比較して非常に高い強度・密度比であり、計算上では車のバンパーにこの素材を組み込むことで時速28マイル（およそ45km）での衝突時の衝撃が時速5マイル（およそ8km）で衝突したのと同等になるとのこと。

現在様々な強度検証実験が行われているとのことで、将来的には車や装甲などの衝撃吸収素材以外にも、地震の衝撃を吸収する素材として建築物への応用も考えられるそうだ。
