David did not kill Goliath with a slingshot[1], the weapon of choice of Dennis the Menace. He killed Goliath with a sling[2], a weapon capable of hurling stones 400+m and one which was regularly used by ancient armies.

I sure hope Dean Kamen will not be remembered as the guy who invented the Segway but as the guy who came up with AutoSyringe and his work on dialysis pumps.
Fun fact: The core of AutoSyringe and his dialysis pumps was delivering super precise dosages of medication. DEKA applied that same technology to the new Freestyle Coke machine (delivering super precise amounts of soda concentrate), in return for Coca Cola helping them distribute the Slingshot.
I've met dozens of students at MIT who say the experience with FIRST was the main reason they decided to study science and engineering. (And I've heard similar stories from folks at Stanford, CMU, etc.)
Dean's a genius with an amazing team, but that impact can only go so far. Inspiring thousands of new students in STEM careers is solving the world's problems at a meta level.
Especially since the Segway was just a spinoff of technology developed for the awesome iBot wheelchair that can balance the user at normal eye-level, negotiate curbs, and even climb stairs. https://en.wikipedia.org/wiki/Ibot
First of all, it doesn't sound like they are "hiring" anyone; that would run counter to being an entrepreneur =).
Second, I assumed the statement meant that Kamen et al. would be especially receptive to local women running the machines. Remember, that women are likely to be repressed in countries where this machine is going to be useful. Empowering women in developing countries has a history of being an effective way to lift people out of poverty. For examples, I point you to the success that microfinance has had in lending money to women.
I don't understand. What happened to his Stirling Engine that was supposed to provide low-cost energy and also produced potable water as a side-effect?
I think that was a common misunderstanding/misreporting, Dean Kamen proposed using the Stirling Engine to power the Slingshot (the Slingshot being the waterpurifier which is mentioned in the linked article).
"But the two devices may fit together even more harmoniously. The generator happens to make a lot of extra heat as it burns fuel -- up to 85 percent of it doesn't get used. But when the generator and purifier are connected by a tube, hot air can blow into the purifier. There, it can do work, heating the incoming water and surrounding the purifier like a jacket, trapping heat inside. With help from the generator, the purifier can be even more efficient."
It creates drinkable water, which is valuable in the absense of drinkable water. But its a stretch to think everybody should use one, to 'save water' somehow. It takes energy to run; that energy comes at an ecological price. In fact, energy and water have been called analogous in ecological calculations (reference?). So it may be a net loss, greenwise, to use this machine to recycle wastewater from your house for instance.
True, but if you have energy that can't be easily stored or transported, it might be worthwhile using that energy to make clean water. For example, the solar panels in 3rd world countries can only charge batteries up to a certain point. The solar cells would still generate energy but there's no place to store it so one might as well use the excess for clarifying water.
I want one of these hooked up to my house - all outbound water should be run through it and i would like to be returning/recycling the water I receive.
At 8K in its current form, that's worth every penny.
They should get the cost to 4K and charge everyone in the developed world 8K for it - get one give one fashion.
Rainwater and urine - ok. But when it comes to human waste (the other kind) I'll rather trust our waste processing / drinking water facilities (as well as a couple hundred kilometers of nature in form of rivers).
One thing that is interesting about this story is the fancy new Coke machines you see that let you choose from a hundred of combination of flavors via a touch-screen was a joint development led by DEKA: http://en.wikipedia.org/wiki/Coca-Cola_Freestyle
Basically this was a method to get their foot in the door and gain trust to a point to get the Slingshot project going, as far as I understand it.
from the article: "this 300 pound, dorm fridge-sized box can take any kind of sewage or even salt water and create 200 to 250 gallons a day of clean water."
Well you are looking at 24-48 kwh per day of use and the article says that the machine purifies ~250 gallons in that time. So approximately 10gph at 1-2kw.
Ideally, one only has to push the water back and forth over its phase boundary by an arbitrarily small delta-T, so the energy consumption can be arbitrarily small too. The 150 J/g is all heat leakage.
I think that localization and distribution of these types of processes like making water drinkable is going to become a huge trend, just because it makes a lot of sense.
For one thing, its easier to scale out in smaller chunks. Its also more robust to have lots of small production going on than to centralize. And technology tends to miniaturize.
I think that there may be other small but incredibly capable devices for producing things like food and goods. This leads to less reliance on more centralized traditional 'economic' distribution systems and greater security for local groups and individuals.
There does seem to be a trend toward more distributed and self-reliant production being enabled by improving technology: 3d printing, aquaponic gardening, biofuels, etc.
Still, the lower-level components and building blocks of the technologies that enable these applications still needs to be designed and distributed, and even those who generate their own electricity, grow their own food, and purify their own water are going to find it challenging to manufacture their own solar panels, construct their own pump systems, etc. More and more hackers might be designing homebrew electronics, but we're still a long way from DIY silicon fabrication.
So it's not that the large-scale, centralized economy will go away; it's that as the value of economies of scale in production of consumption goods diminishes, the centralized production systems and complex distribution networks of the industrial economy will pivot, and end up supplying tools and raw materials more, and finished goods less.
I bet over the next century, we'll see a gradual reversal of the economic patterns of the last 150 years or so, with more and more people adopting a kind of high-tech homesteading, fewer people working as employees for others, and finished goods being increasingly produced by end-users themselves or by smaller cottage industries, with the industrial infrastructure increasingly supplying inputs rather than final products.
