Solar updraft tower [1]
Advantages
- Life span = 80 years. [2]
- Low maintenance costs.
- Cost for 40 years around 1 million USD [3]
- Produces greenhouse areas that can be used for agriculture.
- Produces energy at night (at a reduced rate) [4]
- Produces energy when overcast [5]
- May be able to desalinate water via condensation [6]
Disadvantages
- Takes up a relatively large amount of space.[7]
Economic analysis
- Cost per Watt of capacity = 4 EUR [8]
- Cost per watt of capacity (200 MW): 4 EUR, (50 MW): 6,04 [9]
- 50 MW (Spain, 1800) cost per Watt: 20 EUR[10]
- 200 MW (Spain, 1800) cost per Watt: 12 EUR[11]
Land use
The collector diameter is around 750 m = 400,000 m^2 = 100 acre (60 soccer pitches)[12]
Considering land prices as follows, the solar updraft tower will cost 100,000 - 1,000,000 USD for land only.
- US = 1,000 - 10,000 USD per acre
- Argentina < 8,000 USD per acre [13]
