Pedometer generator
I just saw a photo by TJ Roshan on a human-powered dynamo. One that generates electricity by walking: http://www.urgentevoke.com/photo/human-dynamo-how-energy-from-1?xg_...
This got me thinking... what if you could scale that idea back even further? A pedometer that generates electricty just by walking, through linear induction -- like a "shakey flashlight"?
It would be simple. A shaft inside the pedometer around which thin copper wire is wound. Then a spherical rare earth magnet is placed in the shaft and slightly oiled, like a bearing. With every move, the magnet slides up and down the shaft (or, perhaps, side-to-side would be easier to manage), generating a miniscule amount of energy. Attach that to a small battery pack either attached to the pedometer itself, or slipped into a back pocket (or the entire device into a purse), and voila. Human power through a tamagotchi-sized device.
The details for building your own shakelight, here: http://www.electroniccrafts.org/?n=Main.Shakelight (in case someone wants to either do this, or modify it for the pedogenerator.)

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.
