Ocean Generated Electricity Idea


Some claim the UK is the world leader in developing marine energy technologies and the sector must continue to bring forward innovative new technologies. If the eco-friendly energy requirements of the future are ever to be met then the device known as Searaser goes a long way toward achieving that goal.

Imagine if you will a big aquatic bicycle pump type action device that works to turn wave power into clean electricity. If you can then you get some idea of the innovative new eco-energy source recently introduced by green energy  company  Ecotricity.

 These so-called Searaser machines pump salt water to onshore generators. Having already been tested at the prototype stage their performance much praised by ministers of the government. These people were impressed by the simplicity of the design as the devices employ the rising and falling of large floats to pressurise water.

This technology differs from other wave power generation in that electricity is not internally generated. Hostile ocean environments in which machinery is routinely battered and corroded mean most such technologies are not cheap to produce or maintain but this device is

It is not only cheap to produce with few moving parts but has a great advantage over other designs. This comes through the fact that in Searaser salt water and electricity-generating equipment never meet. This gives the devices far greater potential for cheap energy production especially in the UK, which has vast potential in terms of available wave and tidal power.

Large numbers of such devices could significantly contribute to replacing use of coal and gas power plants. This would mean a huge reduction in CO2 emissions helping control global warming.  It has always been the case that survival of machinery in hostile marine environments has been problematic.

In fact to date only the Strangford Lough – Ireland – based Marine Current Turbines  are producing electricity for the National Grid. All the same Ecotricity founder Dale Vince believes  that these new devices have the potential to produce lower cost electricity than any other renewable energy type.

He confidently expects  that there will be 200 18 metre-deep Searaser devices operating around UK shores by the end of 2016, powering 236,000 homes from wave energy. This energy generation comes through the devices working exactly like  bicycle pumps.

They have need of neither lubricating nor hydraulic oil and the structures are flexible enough to cope easily with the heaviest of seas. Welcome UK government plans to more than double marine energy  subsidies will help speed the process. This is a great step toward a much more environmentally friendly way of generating power and will hopefully lead to much bigger things.
