  Warp-drives are solutions of general relativity widely considered unphysical
due to high negative energy requirements. While the majority of the literature
has focused on macroscopic solutions towards the goal of interstellar travel,
in this work we explore what happens in the small radius limit. In this regime
the magnitude of the total negative energy requirements gets smaller than the
energy contained in a lightning bolt, more than 70 orders of magnitude less
than the original Alcubierre warp drive. Such an amount could conceivably be
generated with current technology by scaling up Casimir-like apparatuses. We
then describe a tubular distribution of externally-generated negative energy
which addresses the major issues plaguing macroscopic warp-drives and propose a
concrete mechanism to accelerate and decelerate a warp. A byproduct of warp
deceleration is the emission of a ray of high-energy particles. The detection
of such particles could be used as the backbone of a faster-than-light
communication device, reminiscent of the hyperwave of science fiction, even
though significant engineering challenges remain to achieve practical
communication.
