An innovative freshwater factory

Although water is very present on earth, 97% is salted and 2% is blocked as ice. There is actually only about 1% left of liquid freshwater and there might be a crisis affecting half the worldwide population by 2030. Freshwater will be a major stake in the 21st century. Indeed the production of a daily food intake for a human being requires 3000 liters of freshwater and the annual rate of freshwater needs is 64 billions cubic meters.

Here's a tower designed as a skyscraper factory to produce freshwater without using any electricity:

A tower that is made of a series of circular tanks filled with brackish or salt water. These tanks are sheltered in spherical greenhouses or 'bubbles'. Saline water is brought up in the tower by tidal powered pumps. Water pipes network is incorporated in the tower's main structure. The 'bubbles' are planted with mangroves (these plants have the particularity to grow on brackish water and to sweat freshwater). So, the mangroves feed on brackish water and then their leaves 'perspire' freshwater. This freshwater sweat then evaporates in the greenhouse and condensates by night into dew on the sphere's plastic wall to be collected in a freshwater tank. With its altitude storage, the produced freshwater can be distributed to users below through gravitational flow. If the total surface of the tower is one hectare, one hectare of cultivated mangroves should produce around 30,000 liters of freshwater a day.

No, not Mr. Bean, but this 'Bean' ….

Castor bean, from the castor-oil plant, was found exclusively in Africa and India for both ornamental and commercial use. It is now found in North America and most tropical regions and is most often grown for ornamental purposes.

Toxicity Level: Even two beans, well chewed, can be fatal.

Effects and Symptoms: Burning in mouth, nausea, vomiting, cramps, drowsiness, cyanosis, stupor, circulatory collapse, blood in urine, convulsions, coma, and death; the toxic agent causes hemolysis of red blood cells even at extreme dilution, severe hemorrhaging results. The castor bean can also induce labor in pregnant women. Autopsies of patients who died from castor bean poisoning show that vomit and stool samples contain blood.

Free-trade

Who designs whose stuffs?
Who manufactures whose stuffs?
Where these stuffs are manufactured?
The reality now is countries are all designing and manufacturing each other's stuffs! And this is the result of economic globalization. This is all happening due to the free trade paradigm the US spearheaded and successfully fought to implement as the world's economic system.
So who should US blame now?
