[W394]What Are The Solar System
by Anna Williams, Ann
This new solar power station is based on solar tower technology designed in Germany. An incredible thing about this new technology is the simplicity of its design, and its ingenious use of basic principles of physics to create energy.

So what is this new solar energy plant?

Also referred to as a solar chimney, this new solar tower uses solar energy in order to turn wind turbines.

Solar energy to turn wind turbines?

How does this work?

Well, the simplest way to describe it is to compare it to a huge greenhouse with a large chimney.

As we all know, hot air rises.

The greenhouse within the solar chimney system captures the heat of the sun. The heated air in the greenhouse is then allowed to escape through a huge chimney.

Before the air escapes through the chimney, it is forced to pass through wind turbines, which are in turn used to generate electricity. You can see a diagram of it here.

The beauty of this technology is that it uses centuries-old tried-and-true principles of updraft. This is the same principles used for chimneys in open fire places. The reason your house doesn't fill up with smoke when you light a fire in your fireplace, is due to the suction created by the hot air rising up through the chimney. This pulls the smoke up through the chimney as well.

But in the case of the solar tower, we are not using a fire to create hot air. We are simply allowing the sun to do its thing: heat stuff up. In this case, the sun heats the air up, and the air then rises through the solar chimney as a result.

Australia is the first country to build this type solar energy power plant for commercial use.

The central tower will be over 3000 feet high and 400 feet in diameter.

It will use 750,000 cubic yards of concrete.

The solar energy collector (greenhouse) will contain thirty-million square yards of space. That's over three and a half miles in diameter.

It will have 32 wind turbines placed at ground level, each capable of creating 6.25 megawatts of electricity.

It will take 34 months to construct.

It will provide a total of 200 megawatts, which is enough to provide solar power in the form of electricity, for over 200,000 households.

The solar tower will create absolutely no carbon emissions, greenhouse gases, or other pollutants in its energy generation process. In other words, it is going to be 100% eco-friendly.

A Contest of a Different Sort

The solar decathlon is an interesting strategy for promoting research and development on solar technology by the Energy Department. The Department selects 20 teams from a bevy of applicants to take part.

To win the competition, the teams are given the goal of creating and manufacturing a home that runs completely on solar power. The home must function as a residence as well as a home-based business and all typical transportation needs typically found with a residential home. The teams are not only required to design and build the home, but they must construct the homes on the National Mall in Washington, D.C. for all to see. The most energy efficient home wins the competition and the university is awarded $100,000 for research and development of solar technologies.

In 2005, the University of Colorado was the winner of the competition with Cornell and Cal Poly finishing second and third. It was the second win in a row for Colorado over such schools as MIT and Cal Poly. The teams for the 2007 competition have been selected and are currently working on their projects:

California Polytechnic State University

Carnegie Mellon University

Cornell University

Georgia Institute of Technology

Kansas State University

Lawrence Technological University

Massachusetts Institute of Technology

New York Institute of Technology

Team Montreal

Technische Universität Darmstadt,

Texas A&M University

Pennsylvania State University

Universidad de Puerto Rico

Universidad Politécnica de Madrid

University of Cincinnati

University of Colorado

University of Illinois at Urbana-Champaign

University of Maryland

University of Missouri-Rolla,

University of Texas at Austin

The teams are due to build their homes on the National Mall on October 7, 2007. With the new interest of the Bush Administration in solar power, perhaps the contest will get a Presidential visit.
