In an arctic climate where there is
access to medium temperature
geothermal a much simpler system than existing low-boiling-point fluid
steam turbines can be built with a convection tower. The major benefits
of this system are simplicity and high performance and potentially
could have lower construction and maintenance cost than complicated
low-gradient fluid
turbine systems.
This system would
perform
well through the cold season and the temperature gradient from
70ºC
geothermal to -30ºC ambient air allows for high efficiency.
Introduction of moisture
to the air lowers density and increases buoyancy, but will probably
cause snow and ice crystals to fall in the local area.
