The magic word is cooked. Mother Nature converted geothermal energy into oil energy when making oil 100-200 million years ago. If we have to supply that energy ourselves, it is tough to get >1.5 EROI. They've just breached the 1 EROI barrier in the lab.

I haven't escaped from reality. I have a daypass.
Actually Mother Nature was very inneficient too -check this piece out:
http://www.eurekalert.org/pub_releases/2003-10/uou-bm9102603.php
-98 tons of biomass per gallon of Gas...!
It's only because there was such a huge amount of stuff to start with that we get anything out. As the bottom of the article says modern processes can be more efficient. I believe Cane Sugar has a higher EROI (around 8?)
What we need is an efficient way to take the algae and concentrate it by extracting the water -possibly by using a solar furnace to boil away the water content.
I think the main take-away from the article is that we have been living in an age where we are saturated with almost free energy and in future we will be forced to appreciate the value of that energy much much more. And I am also coming to think that it means an end to many of the things we now take for granted and we are heading rapidly towards some sort of 'chaotic boundary'/'phase change' -call it what you will. I am loathe to say "the signs are all around us" as that is too close to what a religous nut might tell you about Doomsday -but they are aren't they?! :o)
