Canals only work to move water from a higher elevation flowing downward... Moving water up from sea level to higher elevations requires pressure ( ie pumping ) and pressure requires a fully contained path ( ie piping ).

Come on everybody, this guy is refreshing his page every ten seconds hoping someone will respond to his short, mindblowing post.
Please oblige him and ask him what he means so he can reply with something witty or just plain obvious.
He's right, you're wrong.
The locks system requires a water source at the highest elevation for the water to fill up the lower locks (After you drain the topmost lock, how else are you going to fill it back up without a pump?). Each time the boat changes chambers, water drains from/fills up the locks allowing the boat to pass. Eventually the water flows downstream like it normally would, only it does it in stages.
You cannot move water from a lower elevation to a higher elevation using the locks system, since the water that flows into each successively lower lock will have come from a higher elevation. Since the ocean is lower than inland areas, you cannot get the water to flow upstream using the locks system without a pump, as the other poster said.

Costs of Other Water Sources
A number of California coastal communities are facing water shortages. Although the communities may have relatively inexpensive existing supplies of water, the supplies are perceived as being insufficient to meet community needs. New water supplies are more expensive than existing supplies, and in some cases the prices are comparable to desalinated water. Table 2 summarizes the costs of various water supplies.
In 1991, the Metropolitan Water District (MWD) of Southern California paid $27/AF for water from the Colorado River and $195/AF for water from the California Water Project. New sources of water would have cost $128/AF from the Imperial Irrigation District and $93/AF from Arvin Edison Water Storage in Kern County (if water was available during the drought). (Source: pers. comm. with Bob Muir, MWD, 1991.)
Noninterruptible untreated water for domestic uses in San Diego is purchased from the MWD for $269/AF; treated water costs an additional $53/AF. The least expensive new supplies, other than desalination, would cost $600-$700/AF. (Sources: pers. comm. with Gordon Hess, SDCWA, 1991 and Robert Yamada, SDCWA, 1992.)
In Santa Barbara, untreated water from the Cachuma reservoir costs $35/AF. Development of new wells to use further the City's groundwater basins would cost $200/AF, while new groundwater wells in the mountains would cost approximately $600-700/AF. Enlarging Cachuma Reservoir, if feasible, is estimated to cost $950/AF. During the recent drought, the City purchased water from the State Water Project on a temporary, emergency basis at a cost of $2,300/AF. This water was made available through a series of exchange arrangements with water agencies between Santa Barbara and the MWD. Permanently tying into the State Water Project is estimated to cost $1,300/AF. (Source: pers. comm. with Dale Brown, City of Santa Barbara, 1992.)

It's already being done indirectly. Communities along the coast dispose of concentrate (brine) in shallow, brackish surficial aquifers. The brine then migrates to the ocean water. It's diluted to a point, but the concentration could possibly be higher than the ocean water. I know it's being done in the Florida Keys.
One way you can dispose of the brine directly in ocean water is to blend it with potable or reclaimed water. Permitting is a nightmare to allow such discharges.
ZLD (Zero Liquid Dischage) was mentioned above. ZLD is expensive as shit, but some water producers have no other choice to get rid of the brine.
Deep injection wells (~2000' or deeper) are another option to dispose of the waste...
So what do they use for desalination anyways other than boiling it? The crap dissolved pretty well so do membranes work or is there some other chemical thing...
Do you think submarines take thousands of gallons of fresh water with them when they deploy for a month at a time?
Nope
They have a water system, which desalinizes sea water.

Desalination is very energy consuming.
Subs have a nuclear power plant on board, so the above point isn't a problem for them.

Water flows across an elevation change from the Pacific to the Alantic.
Water is drained in via each lock usage from the Pacific and stored in a Lake halfway across Panama.
The water is drained from the Lake via the filling locks into the Atlantic.

Israel actually made an announcement a few weeks back about a new technology for reverse osmosis that would increase the efficiency and lower the cost of salt water removal.
They actually have a better understanding of the process than the Saudi.

Exactly. So how are you going to move water from the ocean (lower) to an inland area (higher)? He's making it sound like the locks system somehow allows water to flow upstream.

HA!..... That's completely retarded. Do you have any clue where the water used in canal locks comes from? It comes from upstream of the lock ( ie higher elevation ).
Thank you for clearly demonstrating that you have no clue whatsoever.
Obviously you guys have no idea the potential of Locks system:
1. Use locks to move masses of water up elevation for free
2. Unleash water back down elevation (potential energy)
3. Harness INFINITE ENERGY
4. Profit.
