This seems interesting. Planet Eclipse filed a patent that was published today detailing a marker with a rotary breach. No clue if this become a reality, though I kinda doubt it will. But here’s the patent and some pictures from it.
Planet Eclipse Rotor Patent Application
Looks like they applied for this 3 years ago…
This patent has been filed a long time ago. Attached to said patent is a rotary dynamo that is operated by air passing by a propeller of sorts. Presumably the rotating dynamo is used as the cam to operate the rotating breach so they are in sync. The dynamo is used to re-charge the batteries and as far as I can surmise, the marker was meant to be fully battery operated much like the now defunct NPS/KEE E-Volt.
P.S. James is a douche who reveals his sources and shows poor journalistic taste.
