Prior Art – 01/08/2018 Prior Art - Sea Piston Maximum Wave Energy Enabler 2018 Description: This invention relates to a device for enabling maximum energy generation from a piston that uses wave energy or tidal range to generate energy. The Innovation: The Innovation is an adaptation that extends the device above the water. For example a tidal range of 10metres would be a height of approximately //:: 1. Internal sleeve at 10 metres for the tide 2. Plus an amount to account for variable waves, (lets say 1 metre, so a minimum of 11 metres), HOWEVER, 3. The float or outer sleeve will need to cover the inner sleeve and not float away, so add ‘mooring’ of another 9 metres, total height of the inner sleeve will be 20 metres. 4. The outer sleeve will need to be at least 21 metres. The outer sleeve must cover the inner sleeve when the tide is out. 5. Further, if the energy producing mechanism is underwater surface then no further height may be needed. However, where mechanisms such as pumps or generators are above the water surface then the height of such mechanisms must be added to the structure. 6. So, calculation of height of structure plus 3 metre generator will be as follows: 7. For this example: Tidal range 10m + Variable waves 1m + Mooring 9m + Generator 3m = Total height of 23 metres. 8. The Outer Sleeve or float may also be attached to the Inner Sleeve so that a pump action can be achieved, this will make the conversion of Ocean Energy into Linear Energy. 9. However, because of the mooring height attachment may not be necessary and so the adaptation allows us both to attach the inner and outer sleeves together or to have the choice of no physical attachment that allows the outer sleeve to act as a free floating ‘plunger’ while the Inner Sleeve houses a piston and either fixed to the Ocean Floor or (neutrally floating at deep sea). 10. Various shapes can be used and the device can be used in any depth of water, on the beach (awaiting tide) on rocks, close to shore or deep sea.
