    Abstract : Borehole heat exchangers are widely used in heat pumps of residential buildings and industrialsystems. It is known as one of the most energy ecient technologies which provides heatingand cooling by using sustainable geothermal energy. The life time of borehole heat exchangerslasts more than 50 years which is longer than combustion boilers. READ MORE

  3. 2. Sunshade Demonstrator Spacecraft Earth Sphere of Influence Escape Using a Propellant-free AOCS

    University essay from KTH/Rymdteknik

    Author : Leonardo Ricci; [2021]
    Keywords : Solar sail; Solar radiation pressure; Attitude control; Escape trajectory; Centre of pressure; Disturbance Torques; Eclipse.; Solsegel; Solstrålningstryck; Attitydkontroll; Flyktbana; Tryckcentrum; Störningsmoment; Eclipse.;

    Abstract : This thesis provides insights to what is peculiar about a solar sail attitude and orbit control system and provides the assessment, in the form of a feasibility study, of the effectiveness of sail tip vanes as a control hardware to escape the Earth sphere of influence. The demonstrator aims to prove the technology for the Sunshade project, a constellation of solar sails located at the Lagrangian point L1 to obscure part of the solar radiation directed towards earth.
