Purification of salt water

Yet one more low-tech approach to producing pure water. While specifically designed for purification of salt water, it should work with any water that needs to be purified.

This particular product stands out because it is made from locally-made pottery and some metal scrap. No plywood, plastic and such.

It is Open Source you you can build on it. All described in A Simple Solar Oven Makes Salt Water Drinkable.

Think, solve, do.

It's this kind of work that makes me hopeful - people solving real problems. Unlike what I read about a few minutes ago...The Brutal Ageism of Tech: Years of experience, plenty of talent, completely obsolete...

Unfortunately, the problems the average 22-year-old male programmer has experienced are all about being an affluent single guy in Northern California. That's how we've ended up with so many games (Angry Birds, Flappy Bird, Crappy Bird) and all those apps for what one start-up founder described to me as cooler ways to hang out with friends on a Saturday night.

Meanwhile, back on earth...

A 2005 paper by Benjamin Jones of the National Bureau of Economic Research studied Nobel Prize winners in physics, chemistry, medicine, and economics over the past 100 years, as well as the inventors of revolutionary technologies. Jones found that people in their thirties contributed about 40 percent of the innovations, and those in their forties about 30 percent. People over 50 were responsible for 14 percent, the same share as the twentysomethings. Those under the age of 19 were responsible for exactly nothing.

No Sniveling!
