Oh it must. Or at some point when significant parts of the ocean are blocking out the sun. I am all into algae and I think without it all life on earth would cease or at least not have become what it is today.
Alga will probably be what saves the world some day. Maybe not all humans but the world in general.
significant parts of the ocean are blocking out the sun how much would be significant? How many MILLIONS of square miles would that be?
A lot. I think to power London England you need to cover pretty much same amount of surface all all of England just for that city. Crazy.
40 mega watts (or was it 400) might seem like a lot..but small steamers pump out gigawatts.
