OK this splits water into oxygen and hydrogen - not new.  Then it is used to
run a fuel cell - not new.  The fuel cell is a buffer.

What must be new is that is uses a small amount of electricity to split the
water.  Is that so?  If so, are there any figures released?

If it uses a small amount of electricity to split water then maybe this can
be used in autos.  Produce oxygen and hydrogen overnight, or at work, and
run a fuel cell to power the car.  If the electricity is so small to split
and make the gasses, then maybe a battery can do it, or a solar cell auto
roof.

This report is useless unless it at least gives some figures to real world
use.

More information from reuters
http://www.reuters.com/article/newsOne/idUSN3145191020080731?sp=true

"Nocera's catalyst is made from cobalt, phosphate and an electrode that
produces oxygen from water by using 90 percent less electricity than current
methods, which use the costly metal platinum."

So, getting better. 90% less electricity to do it. Still vague in real world
running cost predictions.  Also, cheaper to make!!!  More encouraging.

The PV cell on the roof and fule cell, may be only viable in the sunbelts.

Being a closed loop is good idea too.  Reuters say 5 years to seeing it in
use.

Trust YOU not see the bleeding obvious mistake.

It's very slightly more efficient than the current best by maybe around 10%.



Did you ever learn physics ?



Agreed.
