Floating Solar Chimney Technology
The Energy Problem
 The end of oil is coming;
 The energy demand will be doubled in the next 30 years
 However a major threat is more urgent to be encountered Climate Change
“Clean” Technologies for unlimited and continuous electricity supply
 Coal fired power plants with Carbon Capture and Storage
 New generation Nuclear Fission power plants
 Wind Parks with energy storage system
 Solar power plants with energy storage system
 The missing ideal electricity generating technology to cover 50% of demand
Continuous high quality electricity generation
 Simple technology that can be applied in all continents
 Low construction cost of its Power Plants and low direct cost of the produced KWh
 Zero CO2 emissions
 Zero water demand
Originated from renewable source (better solar)
 Solar Aero-Electric power plants with Floating Solar Chimneys
 Is there an ideal electricity generating technology?
 The reply is yes!!
 The technology of Solar Aero-Electric power plants with floating solar chimneys is very close to the ideal technology
 Indicative picture of a Solar Aero-Electric power plant with Floating Solar Chimney
How SAEPs are operating
 The Solar energy warms the ground below the greenhouse and thus the air inside it (greenhouse effect).
 The warm air tends to escape through the Solar Chimney to the upper atmosphere, replaced by fresh ambient air.
 This up drafting stream of warm air leaves part of its thermodynamic energy to the Air Turbines geared to Electric Generators, converting this energy to Electrical
The Floating Solar Chimney
 The Floating Solar Chimney is made by a set of successive tubular balloons (as shown in the figure beside)
 These tubes are lighter than air due to internal lighter than air gas (He or NH4)
 The seat, the heavy base and a small part of the Floating Solar Chimney
 The body with the heavy base of the Floating Solar Chimney is inclining due to external winds
 The Floating Solar Chimney technology
The main characteristics
 Due to the ground thermal storage they are generating continuous electricity power profiles (24x365)
 It is a low investment cost electricity generating technology, thus the direct cost of the produced KWh is low (less than 6 cents/KWh)
 The technology is very simple and can be applied in all continents using local personnel. Its power plants can be maintained and operated also by local personnel
Estimated construction cost of the Solar Aero-Electric power plants (SAEPPs)
• Thus a glass roof SAEPP, generating 20 GWh/year in MENA area (horizontal irradiation>2000 KWh/sqm/y), of rating power ~4.5 MW, of area ~1.0 square Km, and with an FSC of H~800m and d=40m, should cost ~10.0 million EURO
 Covering the missing 50% of world “clean” base load electricity
 The annual electricity demand is (year 2008) ~20.000 ΤWh
 The annual electricity demand will be doubled in the next 30 years. In 2040 the estimated electricity demand is ~45.000 ΤWh
 The electricity generation by all “clean” technologies is not estimated to be more than 50%
 A large scale application of the Floating Solar Chimney technology in desert or semi desert areas could generate the missing 50% of electricity demand (22.500 TWh), cost effectively, eliminating the global warming threat
