Dean Kamen’s Slingshot water purifier and Stirling generator tech – low cost water and power for the developing world


deankamenslingshot small Dean Kamens Slingshot water purifier and Stirling generator tech   low cost water and power for the developing world

Dean Kamen has unveiled the latest iteration of his power and water package for the third world. The two components are a water purifier called Slingshot that uses a fraction of the power of alternatives and a Stirling engine based power generator that works on cow dung. The $1500 water purifier will produce 1000 liters of water a day, while the $3,700 generator produces around 1 kW, which is enough to deliver light to a small village. The two products have been in development for years, but it looks as though they are now ready for more prime time consideration.

It’s amazing that in this day and age, when investment bankers routinely take home $50 million paychecks, we can’t seem to work out how to help the majority of people on this planet from being at risk through lack of water and power. Astonishing. Here’s hoping things change sooner rather than later.

    I’m afraid price amounts are not quite correct. Currently, purifier and generator prototypes are over $200000 each, but industrial production should lower the price to $1500 a unit. However, these prototypes have been around for a few years now (3 or 4, I think) and still no sign of industrial manufacturing.

  • redc

    I’m afraid the financial side of these products will impact the interest in them…..consider that here in South Africa with the current power crisis more people are investing in fuel-based generators (a 5Kw generator going for R6500 = +- $850). If we’re to help the impoverished third world we’re going to have to come up with much cheaper alternatives. $1500 is almost an annual salary for most africans…..:(

  • Ken Tillotson

    It seems clear that there is an agenda for not wanting this technology available to the third world en mass?? Why??

  • Dave

    Actually, from what I was reading they’re looking to use the same economic model that is being used with cell phones in the third world. Where they provide a loan to a village, sell them the two products and then the village repays them. Karen is actually targeting the third world with this product. The only real question is why financial backing hasn’t been produced to mass market these.

    Hi – I just saw this on TV and think it got great potential – but has to be mass produced – and marketed to get the price points right. I believe that the first step should be to allay the product with commercial interests that could help bring it to fruition. My thoughts are not totally alturistic… I am involved in developing a new water concept that will greatly reduce the amount of PET plastic used in more developed countries provision of water at home and in the workplace. However I feel that we should have a water related charity that passes some of the benefit on to a worthwhile cause… hence if we linked our new product development (which will be highly visible in homes and offices) with a new product that has such potential (but needs to be mass produced to get the price point right) – well then its win win.

    I trained as a Microbiologist but was one of the early movers in Filtered water coolers. I have had a background in Point Of Use coolers (POU) – having built up and sold one of Europes biggest POU companies… so I am sold on the concept of POU. However it does not work everywhere… hence my new idea (see http://www.aqueduct.ie). Link sales of water by us to development and supply of a good pure water system for the third world… seems to make sense??

    What do you all think?

    I find excellent this new invention and I want to stand out their creator's brilliant mind; I am civil engineer and I live in a region of Colombia that calls you Casanare, in these places some communities that suffer illnesses of diarrhea like consequence of the terrible quality of the water that consume, in summer season exist I would like to send some pictures of the water aque they take; it is for it that interests me vastly the SLINGSHOT and I would like to elaborate some project to help there are these families, for what I am appreciated them they send information to know but the product like rhythm in maintenance, their maintenance requires technical personnel, the reserves are easy to get, as I can get it, through who can make orders, in Colombia is sold already in that region, I can install it in properties, etc., I am appreciated him they send the biggest information possible to my e-mail: miguel200176@hotmail.com.

    Thank you

      Hello, Mr.Kamen's Slingshot is not commercially available as far as we know. However, those who are looking for affordable and effective water purifiers we can offer them water purifying units with price ranging from US$300 to US$900 depending on the type of unit client requires. The cheapest ones are the basic model and price increases for the more advanced purifiers. Our email id : samtechshj@gmail.com

    I have seen this product on television and I'm very excited at the possibilities. I'm currently living in Colombia and after having visited some of the northern Caribbean coast, I have witnessed a obvious need for a purifier like this! It's sad really; we're not even talking about the other side of the globe, just a 2 1/2 hour flight from Miami and BOOM! Poverty and death are at our US door step and most don't even realize it.

    Anyone with any further information please feel free to email me at: Info@redtelco.com and if I get some further information I will do the same.

    Bendiciones,
    Gustavo C.

    I think a Kiva type approach may be a way to move, if the price can be brought in at say $2,500. One village at a time I for one would be willing to participate. Setting it up as a loan to be repaid by the first village, then at my option I could roll over the repayment into another village. I like to sell items put the money into Kiva, stuff from my closets that I no longer use, my neighbors know I do this and often contribute, even occasional dumpster diving I sell on craigslist. I help recycle items that would go to a land fill , and help out others. Without effecting my income, which is fixed, I look at it as a hobby in my little work shop I repair the small appliances I can before selling them, what iI cannot sell I donate to the Salvation Army. It is fun, and gives me something useful to do in my retirement.

  • naomi

    right we are in a drawt and this would great please tell me where to buy one

  • Joseph Chu

    I hope there is something I can be of sone help. I can contact some manufacturers in Taiwan or China if I can get some information and details first. To cost down can be

    Hello, I`m very interested in this product and willing to buy it, but can`t find it anywhere… Please send me any details how to buy. Our church does missionary work in India (New Delhi), those people need this Slingshot purifier desperately!
    Please send me info to: shapovigor@gmail.com

      There are other ways as well that might be beneficial to your cause at this time as I'm not sure this machine is readily available at this time.
      Have you heard of Biosand filters? They are used in many places in the world at this time and are inexpensive to build, do an amazingly good job of filtering water from a number of things including turbidity, viruses, bacteria, helminths and even arsenic.
      They don't do everything but they are so much better than nothing and they can be built easily in-country.
      Check out this link: http://www.cawst.org/
      Also google "biosand filters" and you'll find others.
      I am currently working on implementing these in Uganda.
      Cheers and best of luck !

  • SSG Whiting

    Dean,
    I really think the Military should look into the water purifier for their FOBs (Forward Operating Bases in the Middle East. I served in Iraq & am now in Afghanistan and we currently have tons of bottled water being trucked every day. Logistics are very tough when the primary weapon are roadside HME/IEDs.
    Do you have plans for energy producer that runs on paper & plastic waste? These FOBs have a bunch as the serve all their food with paper plates and plastic ware. And they currently burn it all with the smoke often blowing over the FOB with a change in wind direction.

  • Martin Avila Movilla

    Es de verdad sumamente interesante esos sistemas tecnológicos alternativos, por el enorme beneficio que representarían para nuestras comunidades en donde las carencias de agua y energía constituyen una gran barrera para el desarrollo, quisiéramos poder conocer mas información de los sistemas y como poder tener acceso a ellos pues esta dentro de las metas y beneficios que como empresa comunitaria esperamos poder entregar a un gran numero de familias de municipios muy pobres de la región norte de Colombia.

    Dear Mr Dean Kamen,
    My name is Lokman from Malaysia , looking at your Sligshot water drinking machine,I am very interested.Deep in the hinterlands of our Malaysian Borneo states,the unavailability of Drinking water is a very serious problem. I can get anyone of our Malaysian member state to join venture with you to Mass produce your Slingshot water purifier.I believe if my pilot project for the hinterland is successful,we could use Slingshot enmass here in Asian region,thereby creating demand,thus bringing down the product price.I can also get Malaysian Govt grant for project of this nature,Thanks and am looking forward to hear from you asap.Please email me lokmannr@yahoo,com

    They just don't want people to get clear water do they? This machine is simply too complicated to work in such conditions. I myself have built a water sanitizer of commercially available parts producing 8-10 lpm germicide free water (confirmed 99.999% effectivity), runs on solar power. It took me 3 months working in free time. The one off machine at off-the-shelf prices was $3000 with an estimated annual maintenace cost of $2-300. Design life 10 years+. Imagine what that would be in mass production. $200000 LOL

  • sadmanh

    well since this has such a high capability it might just be bought by governments in small numbers & then placed in secured places for public use, or may be charity people would do this. Even if africa might not be able to afford these, there's plenty of people here at south asia who are interested in suck kind of product( provided that it really does cost $1500, cause its supposed to be enough for one village, if everyone there works together they could raise that much cash no problem !) specially due to the idea of cow dung which is intentionally or not priduced largely in this part of the world.
