  In around 5 gigayears our Sun will grow to a Red Giant and will swallow
Earth. The plan is subdivided into two parts: We propose to construct some kind
of parasol to shadow Earth. The position of the parasol will be the (inner)
Lagrange Point L1. If we want to survive also the time beyond the next 5 Gy,
where Suns luminosity and radius increase hundred fold and oscillate until our
Sun develops finally into a White Dwarf, we have to shift Earth into the Kuiper
Belt (50 AU) by means of the swing-by technique During this journey of about
some megayears or more Earth must be illuminated by an artificial light source.
A ring of DD-fusion power stations outstretched on Moons orbit should produce
the necessary 175 PW of visible light. In the Kuiper Belt Earth will be brought
into an orbit of an artificial Sun, an ArtSun formed in the meantime by the
fusion of gaseous Jupiter-like planets imported from other planetary systems in
the neighborhood
