Haha .. and as usual Link choruses .. prove this .. where are your url 
references for your facts .. or, are Link simply meant to believe you?

And, one example (Wikipedia) "The advantage of HVDC is the ability to 
transmit large amounts of power over long distances with lower capital 
costs and with lower losses than AC.  Depending on voltage level and 
construction details, losses are quoted as about 3% per 1000 km. High-
voltage direct current transmission allows efficient use of energy 
sources remote from load centers." http://en.wikipedia.org/wiki/HVDC

Any water used is condensed and relooped. Haha where are your facts re
water usage? I would be delighted to partake in informed discussion Tom
