  Transiently Powered Computers (TPCs) are novel devices that are battery-less
and operate using only ambient energy. Therefore TPCs are prone to frequent
power interruptions, and such the need for developing TPC-centric algorithms is
a necessity. We advocate that only through a common experimental environment,
accessible to everyone, a proper comparison of newly developed algorithms for
TPCs can be realized. Moreover, only through access to various TPC
testbeds---distributed geographically throughout the world---a proper
applications testing and validation are possible. We enlist properties and
features that any TPC testbed should have, calling for more coordinated action
in this domain of TPC research. Finally, we present (to the best of our
knowledge) world's first Internet-accessible testbed for TPCs.
