SEABASED WAVE POWER GENERATOR
Seabased's wave power technology utilizes the water motion in waves to directly drive the wave power plants. The active element is a unique directly driven permanent magnet linear generator. The generator is specially designed to take advantage of the slow movement of the waves that is transferred to it via a buoy (point absorber) on the ocean surface.The buoy action is transferred directly to the generator with no intermediate mechanical gearing since the generator is optimized to output high power even at slow speeds.The movement of the waves (about 15 wave cycles/min) causes the translator (corresponding to the swiftly turning rotor of a conventional generator) to move up and down within the stator, thus converting the kinetic energy of the wave to electric energy. Very powerful neodymium-iron-boron magnets are mounted on the translator. They create an alternating magnetic field which penetrates the stator windings. The stroke length of the translator is limited by end stops at the top and bottom.

HORNIMAN MUSEUM
VISITING HORNIMAN MUSEUM
Victorian tea trader, collector and public benefactor Frederick John Horniman began collecting specimens and artefacts from around the World in the 1860's. Horniman's key mission was to bring the world to Forest Hill and he opened part of his family house to the public so they could view the riches he had collected. As the collections increased they outgrew the family home and in 1898 Horniman commissioned Charles Harrison Townsend to design a new Museum.
The original collections comprised natural history specimens, cultural artefacts and musical instruments.

VISITING THE SITE. CANVEY ISLAND
Canvey Island is an Island lying off the South Coast of Essex in the Thames Estuary, England. The Island is about 3 meters below sea level and periodical flooding continued to blight the small population. The island was mainly agricultural land until the 20th century when it became the fastest growing seaside resort in Britain.
