NOTE:
The cost of the pipelines and the solar ponds power generation/ desalination facilities are
estimated at $10 billion each for a total capital investment of $24 billion (including the
$4 billion for the 1000 well/system grid @ $4 million each). Note that no benefit
allowance is made for either using wells for waste disposal or earthquake control
