Well motivated models of dark matter such as inelastic dark matter and strongly interacting dark matter and other dark relics of stable particles are notoriously difficult to detect in direct detection experiments. This is due to their inability to impart large enough recoil energy in traditional methods of direct detection. In this talk, I propose a new paradigm for direct detection: supplying energy from the detector onto dark matter rather than vice-versa. I discuss two concrete implementations. First, nuclear isomer batteries: long lived nuclear states with trapped energy. This energy can be carried away by dark matter through a scattering event which can be detected. Second, particle accelerators operating without standard model projectiles can accelerate ambient dark matter that carries a small electric charge to higher energies, aiding subsequent detection. The two methods are sensitive to a plethora of as-yet undetectable dark matter models as well as to relic populations of stable particles inaccessible even at colliders opening up a novel discovery avenue.
