Electromagnetic 'Shaky Board' for Energy Conversion
[Category : - RENEWABLE ENERGY]
[Viewed 1202 times]
This patent has been published as a UK patent and a Utility Model in Denmark.
It relates to a new design for an energy-generating device called an electromagnetic 'Shaky Board'. It is so called because it uses the shaking motion of the board to move permanent magnets inside of wire coils, to induce a current. This current can then be collected and stored for later energy consumption. It is the movement of the board itself that is converted into energy, which means that it does not have to align quite so carefully with the kinetic forces, but prefers to be disrupted by them. The new invention would essentially be a wind turbine. The key point again is the fact that the new design prefers turbulent or variable force directions over a steady direction. As the current turbines prefer a steady force direction, this new design could complement them and be used in environments where the current designs would not typically be used. While a traditional wind turbine generates energy from a rotating blade motion, this new design uses an oscillating sideways motion to do the same thing. The design is built around electromagnetic induction and a very basic implementation of it. The electromagnetic device requires that the magnet can move freely inside of the wire coil. It can therefore be suspended at either end of the coil, by being attached to horizontal poles or bars, that can themselves move freely from side to side. The poles are then fixed at either side by supporting structures that suspend the magnet inside of the coil. Small (non-magnetic) springs should also be placed where the unit supports the pole ends, so that when the pole moves in one direction, it can be sprung-back the other way, to help with further movement of the magnet. Another embodiment allows the magnets to move freely inside of the wire coil tubes, instead of suspending on horizontal bars. Because it requires turbulence, vertical poles can be placed in-front of the structure, to generate a more turbulent flow and can even be made to interact with the wind vanes, using springs, for example, to produce further rebound movement. Alternatively, (elastic) rope can be attached loosely to the board and the ground, to again pull it back if it moves too far. The Shaky Board movement is therefore translated into the movement of the magnets, which induce current in their enclosing electric coils, which can then be stored for energy consumption.
