Although it is necessary to live, clean and potable water can be extremely difficult to find in some places where war has destroyed infrastructure or climate change has dried up rivers and aquifers. The Water Abundance XPRIZE is available for teams that can suck cool water all right, and it has just announced its five finalists.
The requirements of the program are quite abrupt to sound almost like science fiction: the device must extract "a minimum of 2,000 liters of water a day from the atmosphere using 100% d & rsquo; Renewable energy, at a cost of not more than 2 cents per liter . "Is this still possible ?!
For a million dollars, people will try anything. But only five teams qualified for the finals, sharing equally a $ 250,000 "stage prize" to continue their work. There is still not much technical information about them, but here they are in alphabetical order:
Hydro Harvest : This Australian team based at Newcastle University "goes back to the basics", probably smart if you want to cut costs. The team has already worked together on an emissions-free engine that turns lost heat into electricity.
JMCC Wing : The leader of this Hawaiian team has been working on solar and wind energy for many years. It is therefore not surprising that their solution involves the "marriage" of a highly efficient and scalable wind energy. harvester with a commercial water condenser. The bigger the generator, the less energy is expensive.
Skydra : Very little information is available for this Chicago team except that they have created "a hybrid solution that uses natural and artificial systems."
The Veragon & Thinair : Alphabetically, this collaboration comes from both sides of the U, but I put it here. The UK collaboration has developed a material that "rapidly improves the process of water condensation" and provides not only to produce fresh water, but also to pack it with minerals.
Uravu : Off Hyderabad in India, this team also comes back to the basics with a solar-powered solution that does not actually appear to use solar cells – the rays of the sun and the design of the device does it all. The water is probably hot enough, though.
The first round of tests took place in January, and the second part takes place in July, by which time the teams' business plans are also expected. In August, there should be an announcement of the grand prize winner of $ 1 million. Good luck to all who are involved and no matter who wins the prize, I hope this technology will be deployed wisely where it is needed.
