Wave energy for Portland
Alvin Smith and Geoff White of Dartmouth Wave Energy Ltd visited Weymouth and Portland on October 29 to hold meetings and a talk about their ‘Searaser’ concept.
In fact, Searaser is more than a concept. It is a fully tested system of generating electricity cheaper, cleaner and safer than anything on the market. It is a bit like a cycle pump under the water that pumps water up on a hill with the help of waves rising and falling. And what can you do with water on a hill? You can let it down through a turbine, and hey presto, you’ve got electricity! See a full description at www.searaser.com
In addition this wave driven water pump can be used in reverse osmosis de-salination, something which can be just as important as electricity if climate change hits the world in a big way.
Some good points of this system are: It is modular and ideal for de-centralised energy production; you can’t make bombs from it; it doesn’t need fuel such as palm oil to be shipped across the globe; it doesn’t leak oil; it doesn’t kill sea birds; it can be used for de-salination also; it produces energy cheaper than nuclear and coal; it is suitable for storing the energy it produces; it is un-obtrusive and less likely to meet nimbyistic opposition.
Anybody got four million? That is all it takes, according to Alvin and Geoff, to build up a wave power station to supply all homes in Weymouth and Portland within four or five years.
The only question in my mind is if the bigger models of the ‘underwater cycle pump’ need to be tested in practice before committing further resources. Smaller models have been tested successfully in Dartmouth by Alvin Smith. The question in my mind is: would a bigger model require bigger wave heights?
I am dismayed but not surprised to hear from Alvin and Geoff that to apply for government loans/support is nearly impossible for a small organisation, with the incredible level of bureocracy involved. It is to be hoped that entrepreneurs with sufficient social and green consciousness step forward. After all: they would want to be ahead of the curve in an industry that must become big very quickly, and provide solutions for the pressing problem of clean energy along the way.
