Spaceship Engine Future
Dyson Sphere - a hypothetical Astroengineering project Frimen Dyson, is a relatively thin spherical shell of large radius (about the radius of planetary orbits) with the star in the center. It is anticipated that the development of civilization can use this facility to full utilization of energy a central star and / or to address the problem of living space.
According to theoretical calculations, for the construction of the scope Dyson needed substance with a mass of order the mass of Jupiter.
Search Scope Dyson - a promising direction of the program SETI. Construction of this magnitude could be detected by existing means of its infrared spectral distribution of atypical (thus Scope Dyson is a powerful omnidirectional emmitter). For these purposes, plans to use the telescope SIRTF.
