Wave Powered Generator to Power Homes 258
Eh-Wire writes "A Scottish company, Ocean Power Delivery (OPD) and it's Norwegian backer, Norsk hydro are set install three wave powered generators 3.5 miles off the north coast of Portugal for the Portuguese renewable energy group Enersis. This will be the world's first commercial wave powered generating system. Providing the initial three generators perform as expected, an additional thirty wave powered generators will be installed by the end of 2006. It's estimated the wave powered generator farm will displace 6000 tonnes of carbon dioxide that would otherwise be emitted from conventional electrical generating plants."

From their site:
A typical 30MW installation would occupy a square kilometre of ocean and provide sufficient electricity for 20,000 homes. Twenty of these farms could power a city such as Edinburgh.
And:
The 750kw full-scale prototype is 120m long and 3.5m in diameter...
So this isn't very different from the power density of, say, wind turbines. It has the advantage that you can locate the 40,000 12m long 3.5m diameter devices - not to mention X00,000 anchoring cables - out of sight in the ocean, instead on the top of ridges where they stick out like sore thumbs and chop the occasional bird migration.
Still, you'd need something lime X000 km^2 to provide all of the UK's electricity this way. With that amount, people will start complaining. Also, their site gives no estimation of cost per kw. A salt ocean with high waves is a very machine-hostile environment, so these devices will have a very finite life time, and at the sizes they give, they are anything but cheap.
So while this is very clever, and nice, it doesn't get us off the hook for a sustainable energy source. Floating nuclear plants, now - that's a thought. Its the ultimate in "not in my back yard".

There's a problem in this. First of all, the little crappy windchop that surfers hate is in the short period bands, 5-8 seconds or so. And these pods will not suck off any of that energy - the chop will go right on through. Whereas the surfable energy - the long period stuff, will be knocked down substantially. Not good. Also, the bulk of the ocean's wave energy is in this chop. So they are throwing out the baby to drink the bathwater.
They need to redesign it to not have any selectivity for periods over 10 seconds - or wavelengths over 100 meters. Take the bulk of the energy, sap it out, and make the oceans smooth and glassy while the long period waves cruise on through and generate stoke for surfers worldwide.
The pod design is really cool. There are a few things they could do to gear it up also - like load the bulk of the weight and volume at the links to maximize leverage, and broaden the aspect ratio closer to 0.5...I'm envisioning links 10m long and 5m wide with never more than 5 connected serially. That saps the oceans of the wind chop, while leaving the longer period surf (which is more rare anyway) alone. Smaller, easier to deploy (and replace) units, which a physical design using more leverage. And surfing would actually benefit from such a change.
