'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.

Speeding up the Debian installer using eatmydata and dpkg-divert

The Debian installer could be a lot quicker. When we install more than 2000 packages in Skolelinux / Debian Edu using tasksel in the installer, unpacking the binary packages take forever. A part of the slow I/O issue was discussed in bug #613428 about too much file system sync-ing done by dpkg, which is the package responsible for unpacking the binary packages. Other parts (like code executed by postinst scripts) might also sync to disk during installation. All this sync-ing to disk do not really make sense to me. If the machine crash half-way through, I start over, I do not try to salvage the half installed system. So the failure sync-ing is supposed to protect against, hardware or system crash, is not really relevant while the installer is running. Read more

Samsung's first open-source conference kicks off, with Tizen on its mind

The inaugural Samsung Open-Source Conference opens Tuesday morning in Seoul, with keynotes from well-known figures in the open source world and a hackathon focused on Tizen, the company’s in-house mobile operating system. The event kicks off with a speech from Jono Bacon, the former community manager for Ubuntu, who recently moved to the XPrize Foundation, and also includes talks from Linux kernel developer Tejun Heo and Carsten Heitzler, the principal creator of the Enlightenment desktop environment for Linux.

OpenDaylight executive director spells out where this open source SDN efforts stand

So if I compare it to Linux. Linux is in my computer, in my car, it’s in a million things outside of the server room. In the same way I think a large percentage of OpenDaylight will be used and leveraged that way. You will have a few people who grab the code, compile it themselves and deploy it in their environment, but mostly for a proof of concept (POC). If an end user hears about SDN and thinks it’s great, they might find themselves needing to POC 15 different solutions. Do I need an overlay? Well, you’ve got to look at three or four overlays out there because they all do things differently. And if you want to figure out how to use OpenFlow, well there are different flavors of OpenFlow, so you’re going to pull a couple of different ones. Read more
