'Wave farm' project gets green light

Filed under
Sci/Tech

A pioneering commercial wave power plant, producing clean and renewable energy, is to go on line off Portugal in 2006, after a contract was signed this week, project partners announced Friday.

The companies claimed the so-called "wave farm" will be the world's first such commercial operation.

The power generators, like giant, orange sausages floating on water, will use wave motion to produce electricity by pumping high-pressure fluids to motors, Norsk Hydro AS said. The Norwegian energy company is a major backer of the project.

The generators were developed by Ocean Power Delivery, based in Edinburgh, Scotland, which signed an euro8 million (U.S. $6.25 million) contract with a Portuguese consortium to build three Pelamis P-750 wave power generators next year.

The project will order 30 more generators from the consortium -- headed by the Enersis SPGS power company -- by the end of 2006, if the initial phase is successful, Norsk Hydro said.

"We believe wave energy will be the new indigenous, renewable resource in Portugal," Enersis chairman Goncalo Serras Pereira said.

The first, three-generator phase of the wave farm would produce 2.25 megawatts of electricity, enough to supply 1,500 Portuguese homes. Norsk Hydro said producing that much energy in a conventional fossil fuel plant would emit 6,000 tons of climate-damaging carbon dioxide.

"This is a significant milestone for our company and for wave energy," said OPD Managing Director Richard Yemm. "We see this order as just the first step in developing the Portuguese market, which is anticipated to be worth up to euro1 billion (U.S. $1.3 billion) over the next 10 years."

The wave generators produce power by using the up and down, and sideways, movements of the ocean swell, moving the flexible, 120-meter (400-feet) long floating cylinders to pump high-pressure fluids to drive hydraulic motors, which will produce electricity in generators.

Most secure Linux distros in 2018

Think of a Linux distribution as a bundle of software delivered together, based on the Linux kernel - a kernel being the core of a system that connects software to hardware and vice versa – with a GNU operating system and a desktop environment, giving the user a visual way to operate the system via a graphical user interface. Linux has a reputation as being more secure than Windows and Mac OS due to a combination of factors – not all of them about the software. Firstly, although desktop Linux users are on the up, Linux environments are far less common in the grand scheme of things than Windows devices on personal computers. The Linux community also tends to be more technical. There are technical reasons too, including fundamental differences in the way the distribution architecture tends to be structured. Nevertheless over the last decade security-focused distributions started to appear, which will appeal to the privacy-conscious user who wants to avoid the worldwide state-sanctioned internet spying that the west has pioneered and where it continues to innovate. Of course, none of these will guarantee your privacy, but they're a good start. Here we list some of them. It is worth noting that security best practices are often about process rather than the technology, avoiding careless mistakes like missing patches and updates, and using your common sense about which websites you visit, what you download, and what you plug into your computer.
