Interesting, but:
- how do you light up on cloudy days or nights (especially for the northern latitudes)?
- what is the ROI for an average house, office complex or larger building?
- how does the device get power for the tracking motors?
- what is the projected availability?

Three questions the article does not answer:
1) How much energy (daily average) does the tracking motor use?
2) Is the tracking motor solar powered?
3) How does one “turn the lights off”, so to speak?
