Energy is the key to
development. Many developing countries suffer from lack of energy resulting in
deforestation,
poverty and population increase, a vicious circle. At the same
time these countries usually have ample sun and arid "useless" land.
This calls for solar power plants which they can afford with their own
resources which are their skillful hands, sun and sand. The Solar Chimney
fulfills these requirements, because it consists predominantly of a large
vertical concrete tube and a flat glass roof. Concrete/cement and glass are
nothing but sand/stone, energy and labor, the energy being supplied by the
first solar chimney itself, which thereafter reproduces indigenously. After a
passing reference to the state-of-the-art in solar electricity generation
(including the author’s own Dish/Stirling-systems for high efficiency decentral
small scale solar electricity generation) indigenous solar electricity
generation will be exemplified by a 200 MW-Solar Chimney. In conclusion it will
be claimed that in the future developing countries could produce solar
electricity not only to cover their own demand, but also for export for the
benefit of the industrialised countries as well.
