Robbing the Sea of its Salt (Feb, 1929)

Robbing the Sea of its Salt

OUT IN California salt is being recovered from sea water in commercial quantities. The pictures below show details of the process.

In this shallow pond sea water is evaporated and its salt content crystallized out. Note the ridges of salt along the edges of the pond.



SOON after water was turned on in a great pipe line in Colorado, trouble began with the joints. There were several hundred of them, all told, twenty-seven being in tunnels through the rock. In some cases, the sand nearby was caught up by the water jets, hydraulic sand blasts were created, and threatened with their cutting power the very integrity of the pipe and rivets.

Sun Still is a 24-inch Vinylite plastic (Dec, 1951)

I just like the giant drinking straw. They should combine this with a Sodastream and use the CO2 for flotation.

Sun Still is a 24-inch Vinylite plastic

sphere which desalts ocean water and makes it drinkable. Black inner bag absorbs sun’s heat and evaporates water leaving salt residue. Vapors condense as fresh water in reservoir chamber. Still provides 2-1/2 quarts daily, folds into small container.

When Rivers Run Wild (May, 1929)

When Rivers Run Wild

by Howard Kegley

California, subject to periodic rainfall and melting of snows in the mountains, has been victimized by rampant rivers in the score of months just past. Told here, the story of the San Gabriel Dam shows the gigantic size of this water impounding monster, and how two rivers will be controlled with one dam.


“I can’t! It just tastes so good!”

I love how they can advertise how inexpensive it is, and also what a big money maker it will be for people selling it all in the same ad.

Wooden Highways That Carry Rivers

Wooden Pipe Lines, First Used by the Ancients, Now Built In Gigantic Sizes


CONVEYING of water for domestic and industrial purposes dates back to early civilizations. The ancient Romans constructed aqueducts which diverted streams of water to their cities and filled their domestic needs. In more recent times bodies of water have been carried over mountains and plains, far from their sources, and utilized to irrigate deserts or to turn the wheels of industry. These modern engineering achievements constitute one of the romantic pages of industrial history, but it is interesting to note that while many refinements have been introduced, methods have been simplified, and quantity production developed, which combine to enlarge the scope of application—the principle has not materially changed.
