The Australian Solar Tower Project By Jayan Hewaparakrama duPont Manual High School March 23, 2009
Currently much of Earths non-renewable energy is being depleted by human consumption
Renewable energy is basically energy that we can recycle and reuse
Energy (radiant light and heat) produced by the sun
Captured by humans
Overview of Solar Tower
The Australian solar tower is still a proposed type of renewable energy.
Base is 3.5 miles in diameter (30 million square yards)
The tower is 1000 meters high
The solar tower contains
collector area (glass/polycarbonate/plastic film)- is able to take in heat from the sun and heat the air molecules under the collector area.
The tower is made from concrete
As the heated air molecules tries to escape through the top of the tower, 32 wind turbines turn generating electricity .
A single 200 Mega Watt Solar Tower
Provide enough electricity to power around 200,000 households.
the number of homes in a city the size of Geelong (major suburb of metropolitan Victoria, Australia).
The energy output will represent an annual saving of more than 900,000 tons of greenhouse gases from entering the environment.

Solar Tower Technology
The sun's radiation is used to heat a large body of air under an expansive collector zone,
According to the laws of physics, hot air rises
hot wind moves through large turbines to generate electricity.
A Solar Tower power station will create the conditions to cause hot wind to flow continuously through 32 x 6.25MW pressure staged turbines to generate electricity.
During the night, the heated ground heats the air molecules
1000 meters above the surface is much cooler, so air molecules continuously travel.
How the Solar Tower Functions
Location of Solar Tower
Australia is an excellent location for a Solar Tower
vast areas of high solar radiation levels
geological stable and low land costs
Project optimization (completed)
Pre-Feasibility Commercialization (completed)
Final Feasibility (underway)
Final Design and Construction
Renewable type of energy
Reduces Global Warming
Cost is too high
Needs a large area
Lot of maintenance work needs to be done in order for it to function properly
