For a spacecraft to acquire a speed of c/10, it would need to acquire kinetic energy, given accurately enough by the non-relativistic formula of 1/2mv2. For a very small unmanned spacecraft of 10 kg, it would require 1/2 x 10 kg x (3 x 107 m/s)2 = 4.5 x 1015 J.

Manipulation of space time IMO is the key
