these are pretty cool little inventions

 

picture a piston anchored to the seafloor

with a cord above attached to a buoy

 

as the wave passes the buoy rises and falls using buoyancy

this is the generator

 

i think this passive collector unlike turbines would be very compatible with sealife

Hi,

here is the link to the pdf by Milton Maciel about sugarcane in Brazil. Keep that link for reference next time someone moves the Amazon 1500 miles to the South.

Hi,

just to correct a few errors:

In Brazil sugarcane is NOT grown on clearcut rain forest land, but has been grown for centuries in the state of Sao Paulo, south of the Brazilian mountain range known as cerrado.

 

And the soils in these canaviais get better from year to year, and have done so for centuries on end. You are 1500 miles off. Consult a world map, or a map of Brazil.

 

Or google for "Milton Maciel". He has laid this out nice and clear in English. He has grown organic sugarcane in Brazil for decades. He knows what he is talking and writing about.

 

By the way, the photosynthetic efficiency of sugarcane in Brazil is 4.8 percent. Pimentel is wrong on this one as well. By a factor of fifty or so. (Seems to be his standard margin of error).

 

The energy balance of corn as grown in the US is negative all the time, no matter if you turn it into chicken feed or ethanol. Stupid chemical agriculture is stupid chemical agriculture.

 

There are better ways. Sweet sorghum from Icrisat in India comes to mind.

Cool, that certainly seems a lot less intrusive and very innovative. :thumbs_up
