Description
Experience Level: Expert
I have designed, in concept, a device that will efficiently condense and collect water vapour from the air.
You will likely have used a device like this before; known as a dehumidifier perhaps in your home.
The objective of my project is to build a device that is as efficient as possible, that runs on battery stored solar energy, and that can be easily 3D printed, assembled and shipped to countries facing constant drought or to disaster zones in need of clean drinking water.
This is a not-for-profit mission and I will be self funding the research & development phase to bring this device, called CloudTap, to reality.
I have created an outline design and worked through initial calculations, but now I need assistance from several specialists to finalise the design. Once an optimal design is prepared, I will construct the first prototype for field testing. After successful field testing I will then look towards scalable mass production and shipment.
I have attached an array of presentation slides I have prepared to this listing.
Essentially, CloudTap will be cylindrical in shape (size to be determined) and will have flexible solar panels wrapped around it for transport.
Upon arrival, the solar panels can be unfurled and laid out appropriately. These will charge an on board battery bank during the day.
During the night, when solar collection is over and air temperatures drop slightly, CloudTap will begin extracting water.
CloudTap will draw in as much air as possible, and pass this air over an array of cooling elements. These cooling elements will be hollow copper pipes filled with liquid helium in a modified compression refrigeration system.
(The copper pipes will be coated with a hyper hydrophobic surface to prevent deposition and icing).
As the air passes through the cooling chamber, the moisture held in the air will be forced to condense out into liquid water, collecting in the base of the unit.
This cold air will then be routed back up and out of the unit after passing over an array of heat exchange pipes from the compression refrigeration system and exhausted to atmosphere.
My documents attached will help visualise this. (Can send a few more for clarity).
I am looking for several specialists:
(This listing in particular is looking for 1. CFD Engineer).
1. CFD Engineer. To take my initial design and test in a CAD environment. This CDF Engineer will modify and adapt the design as needed to optimise airflow through the system.
e.g. Air entrainment at the entrance to capture as much air as possible, efficient cooling chamber design to minimise the time it takes to cool the air, thus increasing the air throughput. Efficient exhaust routing to minimise risk of back pressure.
2. Thermodynamics Engineer. To modify, improve and finalise my initial calculations to describe the operating range of CloudTap as well as calculate the required cooling capacity, the required cooling surface area, the ideal airflow mass, airflow speed through the cooling chamber etc.
3. Electrical Systems Designer. To form an appropriate design for the solar harvesting, battery storage, and operation of CloudTap. This design must fit within the device to enable transportation and must meet the requirements as stipulated by the CFD and Thermodynamics Engineers. e.g. Watts collected and stored, device uptime, cooling system demands etc.
4. Electrical Systems Engineer. To physically build the electrical system that will run CloudTap. I should imagine this will involve PCB construction and strong hands-on electrical knowledge. The design must be easy to fix with basic components where possible to ensure long device life-cycle in operation.
5. 3D Printing Engineer. As much of CloudTap as possible needs to be 3D printed to enable cost effective and rapid construction at scale. The electrical components can then be manually installed within and each CloudTap can then be prepared for transportation.
After the initial prototype is built and producing relevant yield I will look to scale production and source shipping & logistics assistance.
"If you give a man a fish, you feed him for a day. If you teach a man to fish, you feed him for life."
This quote, along with seeing people in drought stricken countries having to walk for miles each day to source barely drinkable water and seeing aid companies handing out bottles of clean water (fish) inspired me to build a device that could capture water from the air around them (fishing rod).
Ideally CloudTap would be the size of a large bin, but may need to be the size of a car or larger. Either way, if it gets clean water to those who need it and it can be transported via truck or airdropped via plane then it should be built.
I can call to discuss in more detail of course as my description here is limited.
Please do help me to bring this to reality.
Looking forward to working with you,
Best,
Drue
