Company Helps Make Desalination More Affordable

Company is reducing the cost of Desalination. A large percentage of the world's population lives near abundant supply of salt water. Energy Recovery, Inc. is engaged in developing, manufacturing and
selling energy recovery devices for selling in the seawater
desalination. There are two methods of producing drinking water from seawater:
thermal distillation and membrane or reverse osmosis desalination.
Thermal distillation involves heating seawater, capturing the vapor and
condensing it as potable water. Reverse osmosis desalination entails
pressurizing seawater and driving it into filtering membranes to produce
pure water and concentrated brine, which is carried away in a high
pressure reject stream. The energy recovery products are used in reverse
osmosis desalination.

That's really good stuff. Getting desalination working on a large scale would go a long way to solving the water crisis. How are they powering the devices? I had a quick look at the website but couldn't see that. It needs to be powered through sustainable means if it is going to have a big impact - solar, wind, tide and so on...

It is my understanding the devices use no external power. They reclaim the kinetic energy of the moving water through the desalination system.

@ Peter Thanks. I just don't see long term clean water security for the human race with out large utility scale desalination. Its needs to be cheap and powered by renewables. There is just not enough fresh water to meet our growing needs. Let me know what you think.

Fourth of July on the Lake

This past weekend was the annual celebration at the lake house in Connecticut. It is amazing that the lake is still so clear and beautiful after all these years. The watershed association has done a wonderful job protecting these waters from the damaging effects of development.The wood grill was finally ready to cook on, so we didn't miss the propane tank fueled grill anymore. The food actually tasted fresher than in the past and was easy to keep fueled.Dad was very proud of the solar hybrid…See More

Stinging Nettle

In this blog post I will focus on a plant that is abundant in our nature, and which is immensely nutritious. It's of course the Stinging Nettle. Let's start with the chemical constituents of this plant:37 % Non-Nitrogen-Extracts19 - 29 % Ash9 - 21 % Fiber4 % Fat22 % ProteinOnce the leaves are drid, their protein content can reach an astounding 40 %, which is much higher than beef, which even under the best of circ**stances can never exceed 31 % protein. In addition the Stinging Nettle consists…See More

FutureToday is 2020/1/1. It is just like yesterday. The war is still continuing. It has started since 2010. In 2010, that year was a horrible year. Almost every energy ran out. Every country’s governments were crushed down at the same time. There were riots everywhere. All of the big company’s bosses were killed xdeadx in the riots. Troops fought each other everywhere. Food was bought up xawayx at once. There were no more food supplies in any shops. The economy was all crushed down. All the…See More

public servants

The exchange works directly for state and public workers and servants. It gives them credit in exchange for the amount of public work they contribute to the community. The more constructive they are based off a base rate the more credit they recieve.
