This paper examines the impact of neoreactionary (NRx) thinking – that of Curtis Yarvin, Nick Land, Peter Thiel and Patri Friedman in particular – on contemporary political debates manifest in 'architectures of exit'. We specifically focus on Urbit, as an NRx digital architecture that captures how post-neoliberal politics imagines notions of freedom and sovereignty through a micro-fracturing of nation-states into 'gov-corps'. We trace the development of NRx philosophy – and situate this within contemporary political and technological change to theorize the significance of exit manifest within the notion of 'dynamic geographies'. While technological programmes such as Urbit may never ultimately succeed, we argue that these, and other speculative investments such as 'seasteading', reflect broader post-neoliberal NRx imaginaries that were, perhaps, prefigured a quarter of a century ago in The Sovereign Individual.

AbstractThe paper describes a unit hydrograph method, calibrated using the WALLRUS modelling suite, which was employed to simulate the long‐term behaviour of storm overflows in combined sewerage systems. It is shown that this procedure synthesizes overflow operation characteristics to acceptable engineering accuracy, measured relative to WALLRUS predictions. This is achieved at only a small fraction of the computer run‐time, and therefore makes practicable a wide range of overflow performance and river impact studies using local rainfall records of unlimited extent.

AbstractThe measurement of flows and recording of storm events at combined sewer overflows are a key requirement in effective urban pollution management. Staff of Thames Water Utilities have developed a low‐cost system based on monitoring the behaviour of flap valves on numerous major river outfalls. The paper presents the development of a modelling approach based on the principle of conservation of angular momentum and its application to experimental data for circular gates. Flow‐prediction accuracies, based on the measurement of gate inclination and water depths, in the range ± 20–30%, are found to be achievable for wider gate openings (<20°) – the recommended calibration offering conservative flow predictions at lower angles.
