Playing for Change

August 10, 2009

Playing for Change is a multimedia movement created to inspire, connect, and bring peace to the world through music. The idea for this project arose from a common belief that music has the power to break down boundaries and overcome distances between people. No matter whether people come from different geographic, political, economic, spiritual or ideological backgrounds, music has the universal power to transcend and unite us as one human race. And with this truth firmly fixed in our minds, we set out to share it with the world.

The Green Wall of China

May 6, 2008

Gobi DesertThe Green Wall of China or Green Great Wall is a project to plant 2,800 miles of forest strips across the northwest rim of China skirting the Gobi Desert. It is consider one of the biggest ecological projects in history. The project will take 73-years of forestation and will cost 96.2 billion over the next decade.

The Director of the State Administration of Forestry, Zhou Shenxian, said “The project will greatly reduce the sandstorm thread to Beijing, upon completion.” The Gobi Desert has been taking grassland over the year, which is a great threat to China agriculture economy.

Gorlov Helical Turbine

March 3, 2008

The Gorlov Helical Turbine (GHT)developed by Alexander Gorlov, a Russian civil engineer, is a newly developed technology that provides a reliable source of electricity by extracting kinetic energy form flowing water.

 Whats most important is that GHT is not as expensive as wind or hydro turbines. Also, has great advantages:

  • No flooding from dams
  •  Minimal obstructions of water flows
  • Reliable
  • Low cost, etc.

It is a great alternative!  Take a look at this example:

 Project Goal: Use Tidal Energy to generate electricity.

Scenario: In the amazon, rural residents are not able to access power lines due to their locations. The only options available to the are solar panels and diesel generator.

 Equipment Needed:

The Helical Turbine rotates on a shaft with a pulley that runs an alternator by means of belt. The alternators chargers batteries when used off the grid.

Results:

  • Accessible Technology
    • About 90% of Tide Energy stations can be built using locally available labor, materials, and equipment.
    • Only the technically refined helical turbine blades are outside components

Benefits:

  • Sufficient to meet basic need of 10 households.
