the big invention likely to come this decade is seawater desalination cheap enough for agriculture. Israel and Singapore routinely desalinate seawater for about %500@acre foot. But there are reports that both are moving toward $400@acre foot. You can grow all fruits and vegetables profitably—but not field crops—at $300@acre foot.
