ParaSol is a datascape, a 3 dimensional diagram showing the annual energy production of AKTINA*, a stand-alone power station. It constitutes also a playful structure, resembling a “huge linear hat”. Across its length, ParaSol gives information about energy production during one year period, while its width shows the amount of electric power produced during one day (08.00am-10.00pm). The artwork is currently part of the exhibition Afresh, A new generation of Greek artists at the National Museum of Contemporary Art. In order ParaSol to get fabricated, open hardware 3d printers have been employed, both in Athens and Rotterdam. For the printing process, City Index Lab collaborates with Fab Lab Athens and EEL/LAK (Greek Free/ Open Source Software Society). The first pieces of ParaSol have been printed during the international conference Creativity (30.09.13 – 01.10.13), organised by the National Documentation Centre. During the two-day event, AKTINA* has been transformed into an open air/ access fabrication lab; 3d printers were functioning, using the electric power AKTINA* was producing, in order to print sustainably and autonomously, pieces of the artwork. ParaSol consists of 84 pieces and is still in progress, being printed sometimes even in situ, in the museum. One of the 3d printers is placed at the linear exhibition space, printing in a real-time show, pieces of ParaSol. Thus, visitors have a first hand experience of the artwork, its production methods and materiality. When all the pieces will be printed, an assembling process will follow and the artwork will take its final position, so the visitors would have the opportunity to experience ParaSol in its more playful aspect.
