Cheap invention makes ocean water drinkable

Dude:

“Chemists with the University of Texas and the University of Marburg have devised a method of using a small electrical field that will remove the salt from seawater.

Incredibly this technique requires little more than a store-bought battery.”

Of immense important to islands that often don’t have easy access to natural water supplies. Of importance to coastal regions.

And should bring down water makers on boats to even cheaper levels.

A brighter future than expected?

An interesting optimistic look at abundance futurism:

It isn’t just aluminum that has become abundant. So have electrical power, refrigeration, television, telephones, cars, and air conditioning. Two hundred years ago, kings and queens didn’t have these luxuries; today, even many people who are classified as poor in the U.S. do. This prosperity has not reached most of the developing world—yet. But the proliferation of mobile phones shows what is possible. Within 10 years, their numbers have gone from zero to nearly 1 billion in both India and China. Even the poorest villagers own them. Mobile phones changed the lives of millions of families who were cut off from each when they went to cities to work and they transformed society.

We are also making headway in solving the global water crisis. Waterborne viruses are responsible for the majority of disease in the developing world. There are predictions that countries such as India, China, and parts of the Middle East will run out of water and that wars will break out over supplies. This seems paradoxical: 71% of the earth’s surface is water, and sanitizing and converting seawater is as simple as boiling it and condensing the vapor. The problem is the cost of energy—it is prohibitively expensive to do this in quantity.

Two exciting solutions to the water problem are already working and ready to scale.
