Tampa Bay Desal Plant
My parents mailed me this article from the Atlanta Journal-Constitution. At the bottom I cranked out some math to compare our's with their's:
Tampa Bay Desalinization Plant
(from Atlanta Journal-Constitution, Feb 17,2008)
Largest in the United States
Cost: US$158M (opened five years late and $48M over-budget)
Annual electric bills: $8-10M
Daily output (average): 25M gallons/day = 100M liters/day
Note: it takes 44M gallons of seawater produce 25M gallons of drinking water (leaving 19M gallons of salt concentrate)
TB Desal Plant
$158,000,000 construction cost / 100,000,000 liters/day = $1.58 per liter per day (not counting maintenance or fuel)
CV Solar Still
Our prototype made 2 liters and cost $213. Or $106.50 per liter per day (not counting maintenance)
So,
TB Desal Plant
$1.58 per liter
CV Solar Still
$106.50 per liter
Surely the cost goes down over time and maintenance is a huge factor, just trying something to size up the competition.
Another way to think about it - the closer we get to a dollar per liter the better off we are.

Hey Bri:....you forgot and important cost element....i.e., operating costs prorated over an extended period of time (i.e., yearly, 5-years, more !)..... as I see it, all / most of the cost to your efforts have already been absorbed in the construction.... I wonder what the de-salination people could offer regarding their 5-10 years costs???......poppi
