Majik Water

Empowering communities with a renewable source of clean, safe drinking water from air.

Explain your project idea (2,000 characters)

Majik Water creates clean drinking water from air in arid areas. This addresses two problems; 1) contaminated water, 844m people do not have access to clean water today; 2) the rapidly growing problem of water scarcity, UN estimates that 1.8bn people will be living in water scarcity in 2025. Our solution addresses the gap by offering a low-cost source of clean, reliable drinking water for people living off-grid in arid and semi-arid areas. We do this by harvesting drinking water from air. We have a proof of concept device which uses desiccant materials to adsorb water from air and is powered by solar for off-grid locations. This generates 10 litres of clean water in 24 hours in 55% relative humidity at a cost of 5 cents per litre. We are currently prototyping our next iteration machine which will generate more water (100s of litres) at a much lower cost per litre (under 1 cent per litre). Our plan is to sell the clean water generated by our machine using a pay per litre model. The impact from our product is that people will be able to access clean, safe drinking water in a low cost way regardless of where they live and the reliability of their existing water sources (e.g. as rivers, wells and boreholes dry up). While we are perfecting our technology and prototype we are starting a water sales pilot to prove low income Kenyans are willing to pay for clean drinking water. Some potential technology investors worry that less affluent consumers will not pay for drinking water, so we are partnering with a children's home on the outskirts of Nairobi to start selling clean water to a) test the market and prove people will pay and b) create employment opportunities for some young adults who are on the cusp of leaving the children's home.

Who are the beneficiaries? (1,000 characters)

For our pilot our beneficiaries are the 80k inhabitants of Soweto village within Kayole, Nairobi. Long term our beneficiaries are families living in water scarce, arid and semi-arid regions of Kenya (and eventually beyond). We will serve two distinct beneficiary segments. Segment 1 is rural people living in arid and semi-arid areas who are at the base of the pyramid in terms of income. We will work with local NGOs or government to install our device in these communities, people will bring their own water containers to a smart tap, pay for the amount of water they want using mobile money and then the machine will dispense it. Segment 2 is more affluent people living in arid and semi-arid peri-urban areas in Kenya. We will create our own branded water bottling stores where we we install a number of our machines to generate c.1,000 litres+ of water per day and then bottle that water in reusable branded water bottles. This water will be sold for less than bottled water today.

How is your idea unique? (1,000 characters)

We are introducing a new water resource in Kenya. We are generating clean drinking water from air using solar energy. Devices which generate water from air already exist in more affluent countries such as the USA. These devices use a condensation coil to get water from air. Wet air is passed through the condensation coil and the water is condensed and collected. This works best in very high humidity, the machines cost £1,000s and use a lot of energy to cool, especially in higher temperature locations. This means it is both too expensive and not very effective in dry, hot Kenya. With our technique the desiccant materials have high affinity for water molecules and they adsorb them, this technique allows us to use the device in low humidity regions and create a device which works using abundant solar power.

In 3-4 sentences, tell us the inspiration or story that encouraged you to start this project.

Our CEO Beth suffered from water borne diseases whilst in university and was driven to start her own water filtration social enterprise that distributed over 5,000 filters in low income communities in Kenya. However, in 2017 filter sales dropped as Kenya suffered acute drought and she started looking realising water scarcity was a big and growing issue. The 3 co-founders met on a scholarship course at Singularity University and bonded over a determination to create solutions for this issue.

Please explain how your selected topic areas are influenced, in the local context of your project (1,000 characters).

For Planet, increasing drought is becoming a regular reality across Kenya as climate change impacts traditional rainfall patterns, so mitigation solutions are needed. For Prosperity, Kenya has historically been a low income country reliant on farming, but recently its service and industry sectors have been driving economic growth. This has led to real gains in income per capita as a whole, but has also driven urbanisation and rural poverty in areas like Kayole. Employment opportunities can be difficult to access in these areas, and basic water, sanitation and electricity infrastructure is often missing. In the long-term Peace will also be influenced by our project; already there are stories of water driven conflict in Northern parts of Kenya and whole communities being forced to migrate in a search for water, this is an issue that is predicted to get worse in Kenya and beyond. We believe that our solution will offer a safety mechanism against this.

Who will work alongside your organization in the project idea? (1,000 characters)

We are late stage discussions with a children's home in Soweto, Kayole called the Good Samaritan to run a water sales pilot. This home has been operating for over 10 years and has an attached engineering shop to provide income, employment opportunities for older children's home leavers and engineering services for the children's home. Majik Water engaged this engineering shop to help build our prototype and realised we had a shared commitment to address water problems in Kenya and also the degree of water problems today in Soweto. Currently the children in the home have to walk over 1km a day to provide their own water for drinking and washing as there is no source in the home, so the engineering firm raised funds to install a deep borehole and water purification system. We realised there was a perfect opportunity to work together to start a water sales business,to provide clean water, create employment opportunities for more children's home leavers and to test Majik Water's pricing

Please share some of the top strengths identified in the community which your project will serve (500 characters)

There are over 800,000 people living in Kayole so all human strengths are represented in this diverse community. Taking a more focused look our partner organisation has already identified 10 young people who grew up in the children's home (5 still living in the home, 5 who live locally; 6 men, 4 women; 8 in further education) and who are looking for income opportunities as they transition to supporting themselves, they will be our initial employees. Additionally our partner is well respected.

Geographic Focus

The sales pilot targets Kayole, a Nairobi slum. Majik Water technology targets arid areas of Kenya.

How many months are required for the project idea? (500 characters)

Within 4 months we will started our pilot water sales in Soweto with the Good Samaritan children's home. The borehole already exists, and the water filtering and tanks are in place, all that remains is to receive the bottling equipment, achieve KEBs certification to sell water and start training the 10 initial employees. For the longer term water from air prototype our next iteration will be complete in 1 month, and our ready to manufacture design will be ready to pilot in 12 months.

What is the cost of your machine? YOu mention that usual machines are costly (USD 1,000 each) and very power hungry.

What are the facts for your machine in its current version?

Very inspiring.

I live in Kenya, would like to meet with you.

Hi Nexus 7 Solar Concentrator 

Sure happy to reply on here, I thought email might be the easiest way to arrange an in person meet-up in Kenya :) We're based out of Kenya Climate Innovation Centre at Strathmore University in Nairobi.

Our proof of concept cost $700 (buying everything retail) to produce 10 litres of water in 24 hours using solar PV. This works out at 5 cents per litre over a 5 yr ownership, but most of the cost was the solar PV panel, which we're engineering out in our current prototype to use solar thermal.

So we would love to learn more about your concentrator - particularly the scale, heat potential and storage duration. We also use the Gearbox hardware makers space with 3D printers in Nairobi, which could be a useful workspace for you if you aren't already aware of it.

Best,

Clare and team

Dear Clare,

Wow, so you are nearby. We are located in Dagoretti, which is somewhere 20 kilometer out of Wayaki Way, and here we build on the prototype model in the modelling tool "LEGO TECHNO" - which we for this project have combined with Arduino (controller), and reflectors, power controllers, sensors etc.

When you say that you want to do solar thermal, there are different ways one can do that. Is your model based on condensation on a cold surface, and then you lead normal air to pass a cooling element and harvest the condensated water?

In terms of thermal, there are many ways to produce COOLING from HEAT, two of the most known ones are the CaCl/Ammonium equilibrium and the Carbon/Methanol equilibrium model, where one would use daytime sun to evaporate the fluctuant media (ammonium/methanol respectively) and then in the night time (after sunset), the evaporation due to the reduction of pressure would create the cooling effect. We have some experience with this which we could meet up and share.

In terms of the Gearbox, I have heard of it, and seen their home page, and it looks promising. I would love if you could introduce me to them?

===

On your questions on our concentrator, everything is publicly available, so, let me start with your direct questions, one by one:

Scale
The system is created in a modular way, such that it can scale from approximately 1 kWatt used for heating up stone storage or direct cooking/water heating (at Equator) up to several MegaWatt (for large scale industrial use). There are several things which are different in the scaled up version, for instance we then have more than one controller. This is a unique approach, because all patents we have studied, without even one exception, are made out of the notion of ONE central controller. Since our controllers are all the same, it came out to reduce the price of the controllers by factors, to simply have individual controllers, each of them completely autonomously controlling their sector of the concentrator, and then address them via WiFi !! That way, we can control a bank of any number of controllers, without a complex, central, proprietary system - we are thereby using international standards all the way through, which both lowers the production price and reduces time to market.

So, when it comes to scale, the modular construction means that we can add more effect in steps of approximately 110 Watt (one reflector) at a time. Our system can practically be made to work with different sized mirrors, however, we have currently designed it such that all the mechanics behind can be made by Plastic Injection Moulding with "small sized" plastic pieces, thereby making it possible to return components for replacement in a simple (Bubble) envelope via normal mail.

It means, though, that for us it would be just a matter of settings to use different sizes of reflectors, and it would not be difficult to do so.

Our current reflector size is 1 x 1 foot, and this is also set like this, due to that we want to make it very easy to get reflectors, simply by visiting any mirror-shop and get the mirrors cut out. What has really taken a long time for us is to compile the hundreds of patents, and distill what could be made with normal production in ways which would ensure a cradle 2 cradle production on the vast majority of the volume of materials, such that we would be starting out with maybe 90% or more of the materials being directly returnable to factory.

Heat potential
You name the wattage and we shall indeed deliver :-) ... Our prototype setup in Denmark (where we are setting up the first full scale prototype) is designed to start out with 2,000 Watt, and we will as part of the scaling test, increase the Wattage to 60,000 Watt, making a full, 400 square meter house 100% supplied with renewable energy for heating. This scaling up can be done in a variety of ways.

When discussing scaling we also have to discuss temperature. We are currently experimenting with bending the mirrors slightly - providing a curvature of some 1/2 degree-arc over the 1 foot mirror. This will, at a distance of approximately 10 meter, concentrate the individual mirror's reflection from being 1x1 foot, to being 10 x 10 centimeter. This will, with for instance the 660 mirrors necessary for the house, increase the temperature tremendously.

In terms of temperature, with approximately 50 plain mirrors, focused in the same spot, it lits fire in dry wood on a clear blue sky day in Nairobi.

Storage duration
In terms of storage duration, this is a question about volume of storage (we use stone), temperature being kept (we aim for 600 degrees Celsius), and the insulation (Here we will be using dry soil).

If you want to know anything else, just ask, or maybe we simply meet up, and you can record the meeting. You are welcome to bring your colleagues, or we could meet up at Gearbox maybe, and have a practical chat?

Sincerely
Nexus 7

That's great you're so close, I'm actually in Israel at the moment taking part in a start-up accelerator here, but my co-founder and our CEO Beth is in Nairobi, so I'll ask her to arrange a good time to visit you guys and also introduce you to the MD of Gearbox (she's on a field trip today).

We are actually using solar thermal for heat directly, not cooling for condensation. We wanted to create a source of water that works in arid areas and with relatively low energy requirements as many communities who struggle with water access live off-grid, so we are using desiccants to gather water from the air, rather than condensation. We use desiccants to capture water in the air, then heat the desiccant material to release the water as vapour and collect that. We just need to heat to 90C.

Thanks for all of the information about your system, that's really helpful! As you suggest meeting in person would be great, I'll be back in touch when Beth returns from her field trip.
Best,
Clare

Dear Clare and Beth,

Sounds great. As well as you are in Israel, I am also travelling to Denmark in a few days, where I will be working with my colleague Thomas, on our Nexus 7 project. We have a goal of building the 1:1 prototype, in the 2 kWatt version before I leave to Kenya, and then afterwards, it would indeed be great to meet up.

My next target in Kenya would be to build the same prototype for Equator. There are some 30+ different things to take into consideration in regards to the difference between 55th and 0th latitude. For entertainment, let me mention: The sun moves across the 0th latitude, from 23.44 South to 23.44 North (solar height) in the course of the year. At the 55th latitude, the sun moves from the 31.56th Northern latitude to the 78.44th Northern latitude, thereby the calculations of solar height and azimuth (solar angle) are different.

In Europe we have nights with frost. This means that if the materials are hygroscopic, they absorb water and disintegrate when it freezes. At Equator, we have peaks of solar influx of more than 2kW per square meter (only deviating slightly throughout the year). At the 55th Latitude the power per sq.m varies between 150 Watt/sqm to 900 Watt/sqm.

Now. Back to your solution - I am looking very much forward to meeting you and your team. One of the most interesting things I ever learned (and tried out, myself, as I did not believe it), is that the cause of condensation is not the temperature, but, that the dew point has been reached (which can happen even at 80 degrees Celsius, as an example), resulting in that the amount of vapor held by the air is above what it can bear - resulting in condensation.

I would love to go through your model with you, and then it could maybe be possible to combine your technology with other technologies to achieve higher efficiency?

In terms of heating up your desiccant for it to release the water (90 degrees) we would be able to create a very simplistically working thermostatic mechanism, which can work together with your system, thereby we can provide either extra energy at that point, or we can maintain a constant (preset) temperature.

Thereby we can adjust the effect produced to fit into various of your criteria for releasing the water. We can already now discuss what your need is, if you want, such that we can hit the ground running when we meet.

When will you be in Kenya again, would you guess?

There are many desiccants, of which some are very efficient, others less. One of the concerns I would have is infestation of the desiccant with spores, fungi, etc., and due to that the desiccant would need to be fine-grained or fine-pored, cleaning would be a necessity, disinfection maybe too?

The reason I would be using a condensation method based on cooling is that one could be using a condenser made of stainless steel, and create it in a way such that disinfection is easy and that all surfaces in touch with the water can be easily accessed and monitored, and in case of contamination, can be easily cleansed.

Now surely you are having some smart means I guess to ensure this, so maybe I am just airing irrelevant concerns.

In the tropical region, there are in existence a range of bacteria which grows and lives (well) in temperatures up to around 200 degree Celsius, or, up to above the boiling point of water. These originate from hot springs, and they live in other places as well, so therefore the heating up to 90 degrees of the desiccant may not sufficiently provide for sterile operations.

We are looking forward to meeting you and your team, and would be happy to be introduced to the Gearbox MD.

Meanwhile let us indeed continue elaborating on everything, such that we can hit the ground running as said.

The object holding the desiccant, how is it shaped? How would we warm it up? We can naturally either "beam it" directly, however, in order to produce a stable heat, even when it is cloudy, we would likely discuss storing the heat from the sun in a small stone-chamber, and then take hot air from there through tubes, and via natural circulation of the air within the tubes, heating up the desiccant. This, however, requires that we sort out the practical issues about that. Thomas and I are very used to solving such practical issues, so I guess we would just have to sit together and draw a bit, and look at what we have at hand, then we can quite likely find a solution and try it out within a few days of net work of our teams.

Just for the sake of good order: If we from our side, by any chance produce any "Intellectual Property", we consider it being in the public domain, not owned by anyone, so feel free to use it without any of the usual (progress-stopping) copyrights and barriers :-)..

Looking forward to the sequels :-)

Great to meet you on this platform. it is a pleasure learning about the solar concentrator you are building. Since I am in Nairobi and Dagoretti is really close to Nairobi is it possible to have a physical meeting with you tomorrow (12th/June/2018) before you leave for Europe?

Dear Beth,

I will make that time, tomorrow, in the afternoon, if that is possible, as I am actually in Westlands, and later I have to be in Nairobi, so if you are able to meet, for instance - maybe - in Java House - then I will do my meeting preparations for my Nairobi meeting already tonight, leaving us with some hours to talk.

I am having a meeting in the morning at 9.30am, which I cannot tell the duration of, and my meeting in Nairobi is at 4pm, so, could we aim for something like 1pm or so in city center, such that I call and confirm once my first meeting is over, then if we both start commuting at that time, none of us will sit and wait for the other, in vain?

My phone numbers are 0711 405 732 and 0707 603 832, and if I do not pick the phone, please call again, as I may be in a noisy place - you surely know how you can have your phone on LOUD, and if you are walking in roaring Nairobi, sometimes you cannot even hear it or sense its vibrations.

Please also share with me your phone number so that we can link up.

I am looking very much forward to meeting you. I think, we owe the OpenIDEO community to minute our meeting, if you are good with that??? If not for anything else, then for inspiration? In our Nexus 7 group we are cognisant of the fact that we would never ever have got this far as we have, without a huge bunch of contributions from people, organisations, wellwishers.

I propose the Java House opposite Nation building, at 1st floor at the balcony, I think it is Kimathi street (?). It is having fresh air..

If you have other preferences, let me know. We can meet also either at Serena at the pool side, (Upper part of Kenyatta Avenue), or at G & R Annex (Biashara street) - G & R simply have the best pancakes in town...

I will record the meeting for my colleagues to join in, later, and feel free to do the same.

Thanks for your swift initiative. Great!
Warmly

Dear Beth,

Where good people are, good people joins :-) - so thanks to you too.

And thanks for the brunch/lunch/coffee, I felt very privileged to be paid for. I am used to such gender equality things in Europe, here in Kenya there is a kind of built in, and very gender-skewed expectation that even in business, a man pays for a woman.

So, it was very refreshening. Next time, though, its on me, then :-)...

My email is ds@rain.yt, and Thomas's email is th@rain.yt - please copy him too (cc) on anything you send to me, such that he is in the loop.

I enjoyed talking with you too about the Majik Project. Thomas and I are looking forward to working with your team, and I hope that we will have a time to meet with the technical team before my departure. Latest date will be Monday next week, so try push the good guys to make it. Unfortunately Friday was suddenly made into a holiday...

I like the concept, the science and the scale. Systems at family level are much easier to maintain than at the community level. I'd like to see a more functional prototype. When will a video of a family-scale prototype be available?

Thanks Kevin!
We agree community level systems can be hard to maintain, which is why we are looking to charge customers per litre of water and maintain ownership of the machines - and the maintenance responsibility indefinitely so we can guarantee our customers are always getting clean, safe water.
We're testing our Kenya fabricated prototype at the moment, so watch this space for an updated video :)

Dear Kevin,

It is interesting that you say so, this with "Family Scale" rather than "Community Scale". We have in our project (Nexus 7) been into exactly the same considerations.

We reached a very hands on and practical conclusion - that up to 4 neighbours can practically, easily, join forces on almost anything, provided (practically - hands on...) that their plots meet up in a corner.

In star-constellations where for instance 6, 8 or more plots meet up in a hub with the plots as spokes in the hub, one can again here, easier share a "community" system between those neighbours.

The real problem comes up, when we begin having these merely theoretical talks where we would be pulling external cables in larger quantities criss crossing between many compounds, or even crossing more or less public roads. The hitherto existing model in many countries, where you deliver electricity to the net in ways where you PAY for instance USD 0.25 per kWh consumed (due to that you pay for the network too), and you only get for instance USD 0.07 per kWh for power you deliver to the net, makes it very useless to share power with your neighbour via the power net.

So, from a very hands on, very practical perspective, I really agree with you.
Sincerely
David Svarrer

Thanks, Clare. Looking forward to it!

David, I would think that would all depend on what service you are delivering. If you are delivering electricity, for example, there needs to be a way to determine who is using what percentage of the whole. When a community-based solution is implemented, there needs to be some monetization built into the system to cover the upkeep of the system, otherwise, the system is not sustainable. A social-eco business is another model that can be sustainable when upkeep / replacement costs are included in the fees that are paid to utilize the service, whatever the service is. On a household scale, with one family, there is no question whose job it is to handle the maintenance. Once you involve two families or more, there can always be the blame game when something breaks that it was the other folks who misused it or overused it. We choose the social-eco enterprise model as can be seen at https://challenges.openideo.com/challenge/bridgebuilder2/review/ecological-cookstoves-and-non-carbonized-briquette-cooking-system-in-haiti-saving-lives-saving-trees-creating-jobs-and-building-community
We are always interested in concepts and feedback. Cheers.

Dear Kevin,

We completely agree with you that it is key for success that we can establish any form of fairness in any distribution system. In a slightly more ideal scenario, where we for instance assume that there is energy in plenty, and the energy is not a scarce resource, let us compare with for instance presence of road-infrastructure - then one can easily imagine a system where everybody pays for connectivity to the electrical supply and not for units counted and measured by the millimeter.

Examples are many, for instance within Internet connectivity, where connectivity in many countries world wide are now paid for the connectivity and neither as a measure of access to speed (Megabytes per second (NOT megabits anymore..)), nor as a measure of bundles (like in scarcity scenarios such as in Africa).

This would then also cater for the distribution of the cost of maintenance of the workable systems plus administration of the service.

It is such that access to energy is not everything. Ability to convert it to something useful beyond the family's need is yet another point. In a community of for instance 50 families sharing a solar energy resource, where everybody pays an equal share no matter the consumption, very fast one or two of the families would develop extraordinary uses of this free access to energy, which would skew the consumption very much, and maybe even cause issues for the other 48 or 49 families in terms of scarcity.

Due to such scenarios and the ones you mention, measurement is unfortunately very often necessary.

Well maintained roads are yet another shared resource, and in EU, lots of effort is put into finding fair ways of distributing the quite huge cost of maintaining the roads in impeccable condition.

In many countries, world wide, local associations and cooperatives are taking care of the fair and just distribution of such resources. Cooperatives, handling for instance energy and water are some of the widespread and successful organisational forms for managing these resources.

Cooperatives have had a success ride for 100+ years, as one of the least corruptible organisational forms. We - in Nexus 7 - are therefore contemplating that one of the channels for distributing solar concentrators / water supply / electricity generation - is via cooperatives where each consumer has one vote, the cooperative is governed by a board elected democratically by the members, and where each member pays according to consumption and also enjoys dividend pro rata the consumption or contribution.

So to put it in short, (now when it is too late :-) ... You are so so right, Kevin, and parts of making any of these good projects successfully scale up, is a similarly scalable business model linked to a fair-play and just load-sharing model.

Lovely with your input.

Your idea seems very innovative. Drought is a serious issue worldwide and the statistics don't lie. Within the next couple of years, millions of people will be without access to a quality source of water. How would you deal with people who have no access to mobile money? Would other payment options be available?

Photo of Clare Sewell

Thanks Vicky. In Kenya mobile money is pretty ubiquitous - there are 28m phone lines registered for m-pesa and the total population is c.48m, so that's good household coverage. That said it does vary a lot, especially in more rural areas so other options like cash could be deployed where needed. And we'll definitely need to investigate this as we look to move beyond Kenya.

Refival sounds super interesting, UBI is an area I'm trying to learn more about, and I think your twist on it answers one of my major questions around "how essential is work for meaning, identity and social cohesion", I hope you start a pilot soon :)
Warm wishes!
Clare
