A self-sufficient interactive sculpture, Solar Powered Door (to Nothingness) stands freely in open space and functions metaphorically as a threshold into the present and new sustainable possibilities. The intended connotations of this symbolic action, walking through a solar powered door, invite the passers-by to participate in a readjustment of society's relationship to technology and the environment, simultaneously suggesting a spiritual involvement through an invitation to the universe. This structure consists of a metal doorway on a plinth and is covered with solar panels on both sides. As a person approaches the door from either direction, it opens slowly, ushering the person into the unknown.

This project was initially realized within the Euregio/GrensWerte programming in 2013-14 and has been additionally supported by the Fachhochschule Münster, Labor für Optoelektronik und Sensorik and the Künstlerdorf Schöppingen 2014-15.

In 2017 discussions began with Wiseguys urban art projects in Amsterdam to locate the artwork in Amsterdam-Ost on a temporary/semi-permanent basis. Funds for an acquisition were procured from the City in 2018, and in the fall of 2020 the artwork was installed on the Wibautstraat in front of the Reclassering Nederland building as part of the Knowledge Mile Project.
