A crash course in changing the world.

Bicycle purifier delivers clean water to the developing world

Once at the water source the rider fills the large tank and replaces the cap (which not only prevents spillage but also helps to avoid contamination that occurs from storing water in open containers). As the rider pedals, the peristaltic pump pulls the water from the large tank, through the filter and into the clean water tank on the front of the bike. By the time the person arrives home they then easily detach the tank from the bike and take the clean water inside ready for drinking and cooking. When more water is required the rider returns to the bike and flips the clutch to disengage the pedals from the wheels. Then, by pedaling the bike which is now stationary, the front water tank fills up again with another two gallons of clean drinking water.

The Aquaduct design was the worthy winner of the Grand Prize in the “Innovate or Die” Pedal-Powered Machine Contest. The competition sponsored by Google and bike maker Specialized, asked people to create Earth-cooling inventions based on the simple mechanics of the bicycle and attracted 102 entries from around the world. Adam Mack, Brian Mason, John Lai, Paul Silberschatz and Eleanor Morgan from California, USA are the inventors of Aquaduct whose combined entry won over the Innovate or Die judges. http://www.gizmag.com/aquaduct-mobile-water-filtration-vehicle/9137/

Great find, that's a great invention in so many ways!

Panamericana, I suppose part of the reason I seem inconsistent is because of the way I answer this type of question.....why do we have to choose? Why can't we/they all work on the problem? I think together is the most influential way to be honest...idealistic maybe, but if we don't at least acknowledge that this would be ideal, then there's no hope of working towards it. This is part of the reason I'm on the fence about the Coke petition.

Hehehe, too funny. I'll admit my dad works in defense...if you read my profile, you'll see what field he's in and possibly why I think the way I do. I'm a little too rogue for the government I think ;)

Haha, ok, I believe in compromise...here are my votes:

I vote for Nick as I said on the first page

I vote for A.V.Koshy, because I see him making a big effort to learn and implement things: http://www.urgentevoke.com/profile/avkosh

And I'm voting for me just to be more of a pain ;) - You know I'm messing in good fun right hehe

hehe ok, I'm going to assume there is a cultural difference and you're not trying to be rude. I'll copy it this time, but please ask nicely if you'd like my cooperation next time.

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**stances can never exceed 31 % protein. In addition the Stinging Nettle consists…See More

Future

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.
