Editor’s note: Dec. 27 story on Greek inventor and clean energy

Editor’s note: There have been questions raised concerning our report that aired on Dec. 27, 2016 about a Greek inventor who is developing a device that purports to turn water into power without requiring additional energy. Despite a team of Greek scientists praising the research, and the inclusion of an independent scientist dubious of the work, the NewsHour acknowledges that our reporting of this segment should have been more skeptical. Our reporting and research should always ask more questions and seek greater insight. We are examining each step in our process, and we apologize to our audience for the lapses in this report. The PBS NewsHour is dedicated to presenting clear and thorough reporting on developments in science and technology, and we will be following up with more reporting on the important subject of clean energy as soon as possible.
