Water Balloons!

Can we solve water shortages and avoid expensive infrastructure by using ships to haul "trains" of water bags from the Pacific Northwest to parched SoCal? Check out Spragg Bags.

Pro: Short-term solution (e.g., Delta levees break and SoCal water disrupted) that is probably better than tanker shipments and desalination.

Con: Encourages living in dry areas instead of wet areas. Not economic if price increases reduce demand below cost of bagg shipping.

Bottom Line: Technology may not solve an economic problem.
