  Yes, I know what you mean! Well thats the price of evolution :)

  Yes we are very lucky. The Caroni river is one of a kind. It has a grea=
t
volume of water and its slope is excelent to get lots of potential. EDELC=
A
(the company I work for) has built three major dams in this river: Guri (=
the
biggest, with around 10000 MW - 20 units), Macagua (with 14 working units
with 2540 MW total) and Caruachi the newest with 12 units and 2160 MW. Th=
ere
is the developing and next construction (finished in 2012) of another one=
,
Tocoma, with the same characteristics as Caruachi. These dams are located=
 in
what is called the "Bajo Caroni" or Low Caroni. Studies had been made and
there are great chances that we=B4ll built more hidroelectrical dams in t=
he
"Alto Caroni" (or Upper Caroni). Nature have been very kind with us, so w=
e
must take advantage of that!

  So Ken, whats your specialty; hidraulics, mechanics, instrumentation?
