And let them help pay for it
proportionate to the percent of the water produced desalinating
through evaporation and condensation collecting in it. Modern earth
moving equipment could make short work of digging a U.S.-Mexico
border control canal from the California mountains to the Gulf of
Mexico. Water would be siphoned up from the pacific and or the Sea of
Cortez to New Mexico and flow downslope in each direction. Sun shine
and solar panels would create power for the pumps. The canals would
be covered with a glassy plastic to let the sun wart the water that
would be a solar still in effect to make fresh water.
The salt produced would have many uses
too. I would think that the millions of gallons of renewable water
could alleviate some California farming shortages and the salt
trivially supply salmon farming concerns using the freshwater too,
built in Colorado and Phoenix (air conditioned) near consumers. Farm
grown fish far away from the oceans is a safe way to produce that
fine food. It also saves corruption of coastal areas from fish
farming derivative effects.
The
trans-continental railroad was built by a great leader; U.S. Grant
who had the leadership skill-set to get it done. Dwight Eisenhower
got the interstate highway system built, started the space program,
nuclear power program, Grand Coulee Dam etc. If President Trump could
get a water-making border control canal system built powered with
sunshine he would indeed rank up their with Grant and Eisenhower.
Mexico may want something for its money if it helps pay for the
canal-such as water and energy from the solar panels generating
electricity. That is only reasonable. Its water and energy share
should be proportionate to its finance participation. If the canal
can produce 50% of the water of the Colorado River eventually that
could be a bargain.
