A crash course in changing the world.

Learn 4 - SLINGSHOT plus a STIRLING engine on the side equals water for the people anywhere , anytime

This is the SLINGSHOT...

he slingshot was first designed in 1993 by Inventor Dean Kamen. I have beena fan of his work for years and this just blows me away. Price point is low and it is simplicity itself in design...

"Kamen claims the Slingshot can take nearly any source of moisture--including ocean water, urine or sewage--and quickly turn it into safe drinking water. The Slingshot process operates by means of vapor compression distillation, requires no filters, and can operate using the most efficient fuel known to man: cow dung. In addition to producing drinkable water, the Slingshot also generates enough electricity to light 70 energy-efficient light bulbs.

In order to push adoption of the potentially Earth-changing gadget, Kamen hopes to seed thousands of the units with local village entrepreneurs, in much the same way independent cell phone businesses have thrived and gradually changed the face of many impoverished areas around the globe. Although not ready for pick-up at your local Wal Mart, Kamen’s future target price for the device is in the $1,000 to $2,000 range (a rather attractive price when you consider what we pay for laptops and cell phones). " (attribution DEVICE)

now you pair that with his Stirling engine ...

Which can run on Cow Dung, make enough electricity for a village, and price point is around 3500 USD and you now have a renewable power supply to generate fresh water anywhere you need it.

So lets get these to Africa, India and all the other places in need of this tech....ASAP and make a differnce...

When water will decrees, this inventions will be reevaluate.

fantastic post Kevin:) +1 for knowledge share. I reckon it would make more sense if these "sling shots" could me fully manufactured or at least assembled in the specific geography that it targets as the user base. that could eventually help reduce the price per unit. the current price (when converted from dollars to rupees is way above what is deemed as affordable in an Indian village at the moment.

this is a good one kevin - if rahul's idea can be also taken into consideration then india could do something with it

Thank you for your words and insight, I agree with all who posted here. I also wonder if the devices could be scaled up... I am currently reading Fred Pearce's book when the rivers run dry ... the decline in fossil aquifers due to irrigation in developing nations is alarming which gave rise to the thought what if you made a large scale Slingshot for irrigation purposes...I shall write Mr. Kamen and find out if it is possible,

Oh and Mr. Kamen has been meeting with people to try to get big business to fund the creation of these devices so the price drops but no word yet on whether they will or not.

Fourth of July on the Lake

This past weekend was the annual celebration at the lake house in Connecticut. It is amazing that the lake is still so clear and beautiful after all these years. The watershed association has done a wonderful job protecting these waters from the damaging effects of development.The wood grill was finally ready to cook on, so we didn't miss the propane tank fueled grill anymore. The food actually tasted fresher than in the past and was easy to keep fueled.Dad was very proud of the solar hybrid…See More

Stinging Nettle

In this blog post I will focus on a plant that is abundant in our nature, and which is immensely nutritious. It's of course the Stinging Nettle. Let's start with the chemical constituents of this plant:37 % Non-Nitrogen-Extracts19 - 29 % Ash9 - 21 % Fiber4 % Fat22 % ProteinOnce the leaves are drid, their protein content can reach an astounding 40 %, which is much higher than beef, which even under the best of circ***tances can never exceed 31 % protein. In addition the Stinging Nettle consists…See More

FutureToday is 2020/1/1. It is just like yesterday. The war is still continuing. It has started since 2010. In 2010, that year was a horrible year. Almost every energy ran out. Every country’s governments were crushed down at the same time. There were riots everywhere. All of the big company’s bosses were killed xdeadx in the riots. Troops fought each other everywhere. Food was bought up xawayx at once. There were no more food supplies in any shops. The economy was all crushed down. All the…See More

public servants

The exchange works directly for state and public workers and servants. It gives them credit in exchange for the amount of public work they contribute to the community. The more constructive they are based off a base rate the more credit they recieve.
