“…On 16 September 2010, a front-end wheel loader malfunctioned and exploded at a wood pellet manufacturer in Aars, Denmark, killing one worker, seriously injuring another, and destroying the building (Hedlund et al., 2014; cf. Hedlund, 2018). In September 2011, a barn on an intensive pig farm in northern Iowa exploded, killing 1500 pigs and injuring one worker (Philpott, 2013; Yan et al., 2014).…”

As Marx pointed out in the second volume of Capital, storage is a critical moment in the circulation of capital. Yet, despite the resurgent interest in the political economy of circulation, logistics, and infrastructures, commodity storage remains under-examined in critical human geography. This paper examines the “hidden abode” of storage by tracing attempts to control moisture and realize value in two different commodity chains: Newfoundland saltfish and American grain in the late-19th- and 20th centuries. Storing preserved codfish and grain presented different biophysical obstacles for firms, but both required interventions to discipline moisture to preserve and realize the value embodied in the commodities. Through our empirical work, we frame storage sites as infrastructural ecologies: complex, more-than-human assemblages that both constrain and enable the realization of value embodied in lively commodities. This paper contributes to debates on circulation, logistics, and infrastructures by highlighting historical geographies of storage as a novel vantage point from which to analyze the frictions and flows of value under capitalist social relations. By grounding logistics in a value-theoretical framework, this paper also contributes to recent debates regarding the value (and valuation) of nature in political economy, by highlighting the role of storage and realization in the nature–value nexus.

“…There are several reports on the hazard of static electrifications. For example, Hedlund [1] shows the evidence of several major explosions attributed to electrostatic ignition of silos with wood pellets in Norway. Glor [2] gives a review of the powder ignition case due to static electricity.…”

In this paper, a device with swinging plate electrodes has been proposed to measure contact electrification of a liquid sample. The proposed structure is composed of two parallel metallic plates immersed in a dielectric liquid. One of the plates is swinging with a constant frequency in a range from 0.4 to 4 Hz. The paper investigates the dependence in time and frequency of electrode velocity and streaming electrification. The measured current occurs for a very low intermittent velocity of less than 10 mm/s. In this range, the electrification current is around 50 pA. For higher velocities of up to 150 mm/s, the current is at the level of 1200 pA. The time–frequency characteristic using short-time Fourier transform shows no temporal changes in the frequency spectrum. The dependence of electrification on shuttle speed was calculated and it can be approximated with a second order polynomial model with the determination coefficient higher than 0.9. The advantage of the sensor is the ability to measure electrification phenomena without the necessity of having rotating electrodes or having a large volume of flowing liquids.
