This technology is essentially the same as hydro, but rather than relying on constant running water, or a lake used for that purpose, the power source is the rise and fall of the tides.
WREN has undertaken a study to look at potential for a barrage type system at three points on the Camel in and downstream of Wadebridge with Vergerg’s Spectral Marine Energy Converter. This system, explained in the video below, has the advantage over barrages that it has little impact upon intertidal ecology and fish survival.
So far, the potential energy source does not appear to justify the capital costs, but if the installation were part of a future flood defence scheme, then the paybacks from the energy supply would pay for the flood barrier.
We also have students looking at various aspects of the tides in the Camel estuary, including monitoring tidal flows at various points, and looking at the modern potential of the old ‘sea mills’ idea.
Vote for locally owned energy
The Wadebridge Renewable Energy Network (WREN) has applied for two grants from Energyfund Cornwall to make a significant step forward for locally-owned community energy. However, to have a chance of winning them it needs to demonstrate support through on-line voting by its supporters for both projects.
The 5 Wren note made its debut at Wadebridge Museum on 30th July.
The Wren is Wadebridge’s local currency, the only one in Cornwall.Read more...
A £10,000 fund is available for community projects to benefit people living in Wadebridge, St Kew, St Mabyn and Egloshayle.
The money comes from the Middle Treworder Solar Farm under a “Section 106” agreement made when it was given permission to go ahead, and is available as grants to voluntary and not-for-profit organisations and community groups in the area around the solar farm.Read more...
