Two fascinating stories came our way today, courtesy at least in one case and possibly both, of reddit.com .
[Don’t know what’s going on with Digg lately, but reddit just has better stuff, and Digg seems to be proving that its flavor of Web 2.0 doesn’t have a clue when it comes to news one can use, and MUDGE hereby expels it from the blogroll.]
So, they both involve water, in a micro and a macro way, with technological solutions to pressing and urgent global challenges.
Story the first:
Written by The Naib
The Watercone is an ingenious device that can take salty water and turn it into fresh water using only the power of the sun. The nice thing about this device is it is bone simple, uses the sun instead of fossil fuel, and is cheap to make and easy to use.
So simple as to beg the question — can it possibly work? So simple as to beg the question — this costs $27.00???
But, take a look at the full story.

Watercone – Ingenious Way To Turn Salt Water Into Fresh Water
What’s utterly lovable about this concept is that it’s high tech in the service of low tech.
2. Absolutely, low concept and low tech.
As opposed to other types of solar stills which feature electronics, photo-voltaic cells, tubes, filters, many parts, etc. the Watercone concept is understood within seconds with absolutely no need for academic background. Additionally it (cone & pan) is made from Bayer Makrolon, a high-tech ultra-rugged and highly recyclable polycarbonate, virtually insensitive to UV exposure or breakage, an all too common result of rough transport.
They tell us that, for the 21st century, water is the new petroleum — highly valued (can’t live without it, until Nestle comes up with bottled synthetic water, manufactured from spent uranium or something!); limited supply.
So, we can provide a solar powered laptop to the children of the third world, and if they’re coast dwellers, solar created potable water to help them reach a thriving adulthood. Extraordinary.
On to story the second, also a technology story involving water.
East River Turbines Face Upstream Battle
The alternative energy company that has plans to install hundreds of turbines in the East River to harness tidal energy and generate zero-emission electrical power is running into trouble due to the massive amount of energy they are dealing with. The small number of turbines already placed in the East River by Verdant Power have been temporarily removed as the strong currents continue to overwhelm the physical construction of the underwater “windmills.” The six turbines that were placed in the water last December and were capable of supplying 1,000 daily kilowatt hours of power and serving the Gristedes supermarket on Roosevelt Island could not withstand currents.
The East River is not actually a river; it’s a tidal strait, and one can easily observe the current moving in opposite directions with the tides. Verdant Power’s plan is to install a field of turbines anchored to the bottom of the East River and use the currents to generate pollution-free electricity for the city. The currents have proven so strong, however, that the turbine propellers have been sheared off a third of the way down, and stronger replacements were hampered by insufficiently strong bolt connections to the turbine hubs.
So, when I first saw this post, I have to admit, I was skeptical — was MUDGE being punked? Does elderly MUDGE even know what punked means?
Yup, of course it’s real, this blog links to a story in yesterday’s NYTimes, which even mentions MUDGE‘s current presidential fixation, Michael Bloomberg. So, okay, I’ve just injected a bit of unreality, but bear with the story, please!

So, here’s an example of cutting edge high tech overreaching. Or, shearing edge. Hard to imagine that the tidal currents are so strong as to incapacitate these water mills. Harder to imagine that they’ve spent a lot of time (and of course some public money) and couldn’t predict the power of water — exhibit A.
And there you have it, an example of MUDGE‘s weird penchant for tying together disparate threads into a unified theme. So, which do you think makes the liquid grade today? Drinking water from a $27 piece of plastic and the sun? Or, hydro power for NYC from a tidefarm that had better be made from materials stronger than granite?
An interesting race that we’ll watch with interest.
In our rush to improve the first and third worlds with all of this wonderful technology, let’s not forget to FIX ALL OF THOSE GODDAMN BRIDGES ALREADY!
It’s it for now. Thanks,
