1 Poem is ‘Pelamis Wave Energy Machine: A Museum Exhibit’ published in Carbon, Watts, and Parish (2017).

2 For discussions of the relationship between land and water in the electricity used for data centres see Hogan (2015), Brodie and Velkova (2017), Bresnihan and Brodie (2023).

3 An evocative video history of the Pelamis wave energy machine, produced by the developers, can be watched at https://youtube/ziLtIbwFXB8. A full technical discussion of Pelamis is given in Yemm, Pizer and Retzler (2012). At the time of writing, the last P2 machine can be seen berthed at Lyness Pier, Hoy, Orkney. It is due to be processed for scrap metal.

5 The poem ‘Pelamis Wave Energy Machine’ is handwritten and available to view online at https://sand14.com/sandbox/pelamis.html

6 For a discussion on digital traces and the energy residue from deleting data see Thylstrup (2019).

7 I have written at length about the marine energy industry, including Pelamis, in my book on the energy future in Orkney, the site of the European Marine Energy Centre (Watts 2019).
