Abstract

A generator to produce electricity from flowing sea water comprises a non-magnetic tube 1 on the outside of which are permanent magnets 2. Within the pipe are two electrodes 3 made of a non-corrodible metal. In use, as sea water flows through the tube, it passes through the magnetic field created by the magnets. This process creates electrical energy which is received by the electrodes. The magnets and electrode leads are protected from corrosion by the sea water. The generating unit may be mounted in a bank of multiple units to increase the amount of electricity produced.

Description

An electric generator The invention is of a novel unit for generating
electricity from flowing sea water, as in a tidal flow. It is based on the principle that conducting fluids react in a magnetic field in a similar way to solid conducting wire.
Fleming's rule left hand rule is applicable The generator consists of a tube or duct ( I), the tube being of non conducting non magnetic material, such as a common plastic.
Electrodes (3) are fixed within the tube, the electrodes being of a material not subject to corrosion such as non magnetic stainless steel. The sea water flows through the tube and between the electrodes. The tube is located between the poles of a magnet (2), the flux being normal to both the flow and to the electrodes. The electrodes are connected through the tube wall to a battery or other electrical device. When the water flows an EMF is generated between the electrodes.
There are a number of devices for generating electricity particularly from waves in the sea but none have proved really practical and there is at least one generator using tidal flow, this has multiple turbines. It is expensive and requires much maintenance. The invention described is simple being basically a straight through tube with no moving parts, thereby requiring virtually no maintenance.It is also relatively inexpensive.
The attached schematic drawing shows a basic design.

Claims (2)

1. A unit comprising a nonmagnetic tube on the outside of which are magnets, inside the tube are electrodes, with the magnets and the electroded at right angles to each other so that when sea water flows through the tube electricity is generated.
2. The unit as described in claim 1 is mounted in a bank of such units to enable more electricity to be generated 3 The magnets are protected so they are not corroded by the sea water, the leads from the electrodes are similarly protected a, if- a; 1 2 336.
