  27. Conclusions • Photonic Laser Thruster (PLT), a recycled photon thruster, is projected to overcome the tyranny of the rocket equation, if scalable. • Photonic Laser Thruster has been successfully demonstrated in lab. • PLT permits the near-term applications that can generate investment returns. • Stepping stones for developing large scale PLTs and Photonic Railway. • PLT flight demonstrations in earth-orbits and mission studies and demonstrations are proposed to be the next logical steps. • The science and technologies, such as Bose-Einstein condensation of photons, which can overcome the diffraction limit of laser beam propagation over long distance, are recommended for the near-term R&D.
