A Thermal-Solar System for De-Orbiting of Space Debris

Autor: Silivestru Valentin, Sandu Constantin, Vizitiu Georgel, Sandu Radu Constantin, Teletrans, Craiova, Romania, Filipescu Bogdan, Braşoveanu Dan

Publikováno v: INCAS Bulletin, Vol 10, Iss 1, Pp 27-38 (2018)

This paper presents a system for removal of space debris, which can be placed on geocentric, heliocentric or Sun-synchronous orbit. The system is composed of two parabolic mirrors, a large one and a small one. The concave face of the large parabolic

Space Technology for Reduction of Desert Areas on Earth and Weather Control

Autor: Braşoveanu Dan, Teletrans, Craiova, Romania, Silivestru Valentin, Sandu Radu Constantin, Sandu Constantin, Filipescu Bogdan

Publikováno v: INCAS Bulletin, Vol 10, Iss 1, Pp 39-49 (2018)

In precedent papers the authors presented the idea of a space system composed of two opposite parabolic mirrors (large and small) having the same focal point. This system is able to concentrate solar power in a strong light beam having irradiance of
