The world’s first commercial-scale wave power generators are online in Portugal.
A couple of questions I have about these:
How many of these facilities can you put in before they start affecting shipping traffic? What’s the maximum wave these can deal with (ie what happens when there’s a tsunami)?
Gosh, I hope this doesn’t cause the earth’s rotation to slow at a rate of .00000006 mph per day, thus ripping a hole in space-time and opening a doorway to the fourth dimension.
It obviously won’t bother the ocean traffic, and it has cost a mere 9 mil to supply the anual needs to 150 000 city houses.
Pedro, the article talks about these three devices powering 1500 homes, not 150,000.
Just for interest I thought I’d check what the numbers look like for real industrial-scale power, 1GW.
€9m for 2.25MW peak scales to €4billion per GW peak, which would require about 180km of shore frontage and nine hundred thousand tons of steel to construct. According to the article numbers. Best number I have seen for wave capacity factor is 40%, so for 1GW average generation you would need €10billion, 350km of shore and over two million tons of steel.
