Hey, Suzanne.

 EC>> Holy cow.  There is no energy to "harvest" in water.

 ST>  The above line says they're harvesting sunlight.

So it does.  Guess I was too quick on the trigger.

It's as if it is at the bottom of a deep well.  It's mechanical energy can 
be increased by raising it up to the top, but that requires even more energy 
than the increase, and so is no energy source.

 EC>> Already most of our energy comes from the
 EC>> sun, so that is not new.

 ST>  Of course, it's all relative.  <g>  The sun is so ooooooold.  :-)

Huh?

 EC>> What these guys seem to be predicting is the
 EC>> development of a better way to
 EC>> capture energy from the sun - as it arrives.

Now that agrees with your first point.

 ST>  You mean like a fuel cell?

You must have deleted the comment that you are responding to, but yes, the 
so-called fuel cell is nothing but a storage device.
