LightCraft Space Center
The Universe has always exerted a magical Fascination on Humans. The importance of Space-Travel will increase dramatically in the Future. But how do Humans or Satellites get into Space?
Currently   only   by   means   of   Rockets.   In   order   to   reach   outer   Space   -   i.e.   to   reach   an   Altitude   of more   than   100   km   above   the   Earth's   Surface   -   one   needs   a   Propulsion   System   that   can   generate the   necessary   Power   to   overcome   the   Earth's   Gravity   and   still   function   in   a   Vacuum.   The   only known Mechanism that meets both Conditions is a Rocket. A Rocket Motor exploits the physical Law of force and Counterforce "actio = reactio": When   the   Rocket   ejects   a   Mass   Backwards   at   high   Velocity   (this   is   the   Action),   it   produces   a forward   thrust   in   Reaction.   In   today's   Rocket   Engines,   the   Energy   required   to   accelerate   the ejected   Mass   is   provided   by   the   Combustion   of   a   chemical   Fuel;   the   Oxygen   used   for   this   is carried in a separate Tank. Due to the enormous Quantities of Fuel, the Ratio of launch Weight to Payload is extremely unfavorable for a Rocket: It is 2.8% for the European rocket Ariane 5 and only 1.3% for the American space shuttle. An Ariane with a launch Weight of 700 t can therefore Transport a Payload of just 6 t. In order not to have to build rockets all the time, the space glider returning to earth was developed. However, the hoped-for major savings did not materialize, partly because of fuel and maintenance costs. What engines will the spaceships of the future have?
The   big   challenge   is   to   overcome   the   force   of   gravity.   To   do   this,   incredible   efforts   are   being   made,   with   extremely   poor efficiencies. To   escape   this   dilemma,   a   technique   has   been   developed   that   also   uses   the   repulsion   principle,   but   where   the   actual fuel remains on the ground and does not have to be taken into space. This system is called LightCraft   In theory, it works in a fascinatingly simple way. A   highly   energetic   laser   beam   explosively   vaporizes   a   material   in   the   drive   chamber of   the   object   to   be   transported   -   thus   the   recoil   is   generated   and   the   object   moves away from earth. Targeted   laser   shots   are   fired   at   the   material   in   the   combustion   chamber   until   the desired height is reached. Once   this   technology   is   able   to   shoot   larger   weights   into   space,   it   will   revolutionize the entire space travel. Our   thermosolar   power   plants   produce   a   large   amount   of   electricity,   so   that   we could   transport   several   objects   into   orbit   every   day   without   weakening   the   normal energy supply. One would store the electricity produced during off-peak periods. If   we   succeed   in   developing   such   a   cheap   means   of   transportation   into   space, travel into space will become commonplace. Once one has escaped the earth's gravity, one continues with electric propulsion in space. Light-Craft   would   not   only   be   an   extremely   cheap   system,   but   also   absolutely   environmentally friendly, because it is essentially powered by solar energy. The   development   partner   will   be   DLR,   which   has   already   gained   considerable   experience   with light-craft technology. We will continue to report on this exciting new technology here.
