contribution to a conservative policy for hydro-
carbons both by increasing the renewable energy
share within the international energy balance and
by improving the living conditions of isolated
communities. The fi rst operation of installation
of PV plant in Saida town, considered to be the
gate of the Algerian Sahara, would allow on one
hand the electricity supply and on the other hand
to collect information about:
agricultural, environmental and science and
technology development solution. In particular,
through desalination and adequate irrigation
technologies, it will help mainstream marginal
desert water resources and lands back into
national, regional and international development
processes as shown in Fig.

understand the limitations of our 'mental maps'
of the world - to think the unthinkable, anticipate
the unknowable and utilise both to make better
strategic decisions.

SSB will then ensure an energy/climate secu-
rity with global justice and development of civili-
sation for the whole world, a clever global
development strategy for solving the energy and
climate problems with existing solar-grade Si
production from Sahara sand technology for a
sustainable world. Sahara has plenty of silica as
primary material for Si and sunlight as solar
energy source. Table

generation capability (evaluated from material
needs, effi ciency and natural resources) of differ-
ent solar cell materials. Moreover, SSB is an inte-

Material and energy are key components of our
life and indispensable for sustainable develop-
ment of our world. There are two renowned big
benefi ts of Sahara and other deserts from the
viewpoint of energy utilisation, i.e. vast land and
ample sunshine, which attract much interest for
harvesting new clean energy from deserts. The
SSB project we proposed and started initiative
R&D with Algeria is aiming energy harvest from
