Urgent Evoke

A crash course in changing the world.

His system of water purification might be one of the most amazing on the market today.
I know many will pick this solution, but I really like it and was waiting for the water crisis topic to post about it.

An article about the system:

This is the link to his company and research centre:

Good choice Kenneth.

FYI - I have emailed Dean Kamen to ask for some more information from Deka on the slingshot system and perhaps lend his weight as a mentor here on EVOKE. As yet I've not had a reply but I remain hopeful!

I hope he'll reply!
He's one of those people who could inspire and help us a lot on Evoke.

I loved it. the idea or recycling the heat is phenomenal.
The only thing I couldn't find was an estimate for a price. see anything?
Comment by Helene Lavertu on March 25, 2010 at 6:00pm
In the text it said it hoped to be less then 2000$... american, i think?
Comment by Omri or something on March 25, 2010 at 6:10pm
That means that if you price water at 20 cents a liter it would take 10 days to pay itself back.
at 2 cents it would take 100 days (or 3 months)
good deal.

Yes $2000 is the plan. However there is a catch. They currently can't sell enough units to be able to generate the economies of scale that bring the price down to that figure. It is significantly higher at present...we need to help solve this!
Comment by Helene Lavertu on March 25, 2010 at 7:19pm
How? By each buying one at inflated price?
Comment by Helene Lavertu on March 25, 2010 at 7:20pm
Sorry Ben, hard to keep the scepticism, especially in a written message, should have phrased it better, no hard feelings :)
Comment by Omri or something on March 25, 2010 at 7:20pm
Well, if it costs 2000 to make 1000 ltr. of water a day, it would make it cheaper to desalinate water in Israel than what it costs to buy tap water. at 2000$ it would be worth while to buy lots of them.
on the other hand it would be great if they can scale up a little for very high demand.

LEARN1- Social Innovator

My favorite, and perhaps most needed social innovation today, is "Don’t fight culture (If people cook by stirring their stews, they’re not going to use a solar oven, no matter what you do to market it. Make them a better stove instead.)"This simple idea has two meanings. First, it shows that the injustice of poverty and instability does not have a cookie cutter answer. Rather, it takes domestic and well educated responses that address the factors that drove a culture to suffer so, such as from…See More
