Michael Pritchard's water filter turns filthy water drinkable

From TED: Too much of the world lacks access to clean drinking water. Engineer Michael Pritchard did something about it -- inventing the portable Lifesaver filter, which can make the most revolting water drinkable in seconds. An amazing demo from TEDGlobal 2009.

Well, that simply could not be any more impressive. A total solution to the entire water problems of the planet. Too good - but still true !

Now this is cool technology. However I worry that this is not just providing a "band-aid" and not addressing more long standing issues such as fuel consumption for boiling water (the most tried and true method of water sterilization). In sustainable technology, we must realize when our tech is not what is needed for the world at the moment, and "step aside" for those with more far reaching needs. Though this technology is absolutely freaking brilliant, I wonder if a new cheaply produced stove that boosts fuel usage efficiency might not be much more effective at providing for a range of issues from hygiene to drinking water. I personally favor ideas (as I am sure many of you have heard of) such as the briquettes or small brick stoves. I do however really like the idea that this product is not offered for free. People often don't have a want to change to a new system when it is not "desirable". Make it popular by making one need to purchase it, and vola, the rich buy it, the poor want it, and it is used (as a paraphrase to how the theory goes).

This is a brilliant bit of technology- honestly, I'd want one just so I could drink on the go while at the beach, outdoors, etc. However, for it to succeed, it really needs exposure so people can latch onto it, see it, and this demonstration really works. I like it a lot, so I may have to throw this one up somewhere in hopes of it getting more fully embraced. Very topical considering the recent Haiti crisis. Thanks for passing it on!

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.
