Solar Water Energy, LLC’s Solar Desalination Plant
Dear Evoke Agents,
Let me share with you an important discovery:
Solar Water Energy, LLC’s Solar Desalination Plant
Please have a look:
http://www.solarwaterenergy.net/solardesalinationplant.html
Of all water on earth, 97.5% is salt water. This is where we have to investigate. If we can find a reliable and cost efficient way to transform salt water in drinking water, we have a sustainable solution. The technology already exists, but it consumes a lot of energy to operate. This new technology works with solar, so solve another important problem.
It has many necessary functions to help a lot of people in the need of a solution. It is an innovation that I truly support.
Needs are very present, and in some cases urgent. But there are solutions. Here is one of the best, for large scale high impact progress, and a sustainable solution!
Please take a minute to comment and support

I love the concept; but what shall we do with all the salt we will potentially also 'create'? We cannot put this in the sea on a large scale because the volume of sea water left through this process shall decrease, making the salt to water ratio higher. However, the salt can not be put on the land as salinity would become an issue - or become more of an issue in places like Australia, which was once an inland sea. Eating the salt could work, but we already have enough salt, no? If we were to use it in third world nations then I would strongly discourage the intake of salt too, seeing as it leads to thirst.
However, this technology could potentially be used in Africa, America and Europe. Places like Japan or the UAE where pollution or dust particles exist in ma**** in the air, however, would be disadvantaged by way of being unable to get enough sunlight to actually hit hit the soar panels.
However, I do quite like the idea, it could potentially help us on a large scale to a more sustainable future.

Great post.
I wouldn't be afraid of salt levels going up in the sea. the amount of salt we would put back in is so small it would not at all be felt by the huge ocean. plus, we could use it to spice food anyway.
I've been thinking of these sorts of things as well. I think Stirling heat engines are the best for solar water plants. or we could just fit a solar panel on a Deka system.

Inaccurate figure 97.5% salty water. What exactly lead you to conclude on that percentage? I agree that we more water in sea which is salty, but that percentage is inaccurate and misleading. You need to give us more information which lead you to such conclusion. You can't just place a wrong % on network and think that I can agree on it. It is true that we need a plan to transform salt water into drinkable water. It will cost us a huge amount for Technologies and other resources, but it is really worth it. Think about your %.

Amber, Crystal, I think I would join Omri on the issue of adding salt into sea, on a proportional basis, I think it would take a lot to change salt level into the ocean as to create a problem.

Bongomusa, the 97.5% figure is coming directly from this week's mission briefing: Discover the fast facts: What is water security? and provided by the web site Facing the future, thanks

You know what, I am concerning about the salt water since I was ten or something. When I was a child, it is weird for me to know salt water is not edible. I highly recommend your concept. Transformer!!!

+1KS. Israel launches its Desalination Master Plan in 2000. Today, Israel has the largest desalination plant in the world - Ashkelon Desalination Plant which produces around 13% of the country's domestic consumer demand. Good example of policy and subsequent action producing positive outcomes.
But aside from the salt issue, there is also that fact that desallinations plants are relatively expensive to build, consume large amouts of energy to operate, reduce oxygen levels in the air and results in an increase of the density of any discharged waste water as well as increased greenhouse gas emissions. How do we balance cost v/s benefits?

Shakwei, Miaomiao, For now I understand it is not a perfect solution, because of energy consumption and others, The proposed desalination plant here is solar powered, a plus. Thanks

I like the idea. But I can't do any of the calculations as I don't know what m3 means? is it liters, gallons or something else? I would love it if you could tell me.

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.

The meal
It is 7'oclock, I was late home from work due to an assignment that i wanted to get ahead on. By the time I get home I am feeling extremley tired and I cannot be bothered to make a proper meal. I walk to the fridge and open it to see what there is for me to eat. All of the out of date foodstuffs have been automaticaly thrown away by the fridge, they will be recycled tomorrow as animal feed or something. I see i have organic local eggs and some local cheese.
