Found this article on cnn.com about wave energy. Thought I would share it.

Very interesting.

So, I figure there must be about the same number of homes on STX (article referred to 15,000 homes; I'm guessing there are about 50,000 people/2.5peoplePerHome = 20,000 homes).

I wonder what the effective cost per kWh is (2.2 MW for 9M euros... how long do they last... what's the maintenance cost... and install cost... integration into existing power grid...)

And I'm guessing that you'd want them on the east end of the island (is that where the most consistent waves are, given predominant easterly winds?). So, are they ugly? Are they navigational hazards? What happens in hurricanes?

good stuff to consider...

The article had pictures of the wave machine..................big red wiener bobbing about!
Solar, wind & water are an abundance here & we should harness them & give WAPA the boot.

Yeah, hard to tell how obscene they'd look from Point Udall... but, at 140m length.... ouch!!!!!

Ohhh, I know how to tell... so let's just say 1/2 mile from Pt Udall... this is how it'd look:

The article said they were located about 3 miles off the coast. I wondered the same thing about hurricanes, maintenance, etc. But, depending on the longevity, maintenance, etc, 9 million euro (18 million dollars) might make it a renewable system that is affordable. Since it is just a prototype I guess we will have to see how it goes.
