Bartaku is an artist / researcher (Brussels; °1970) who is inspired by systems thinking and driven by quest.

Through interventions, installations, residencies, talks and public labs he explores troping of light and language -both human and non-human. After having explored the wind up realms of threads through various installations, in 2007 he started the ongoing research PhOEF: The Undisclosed Poésis of the Photovoltaic Effect.

The most acclaimed PhoEF-node is the "temporary PhotoElectric Digestopians (tPED) Worklab" series: public experimental labs in which the Sun is caught and translated into electricity via a digestible solar cell that is subsequently experienced on the tongue. These moments of transformation of light are photographed resulting in a growing portrait gallery.
