Distributed Cell-Phone Based Night Surveys


Utilize billions of phone cameras, while charging battery at nights, to watch the sky for phenomena.


Many of us geeks and nerds know that long-exposure night photography works pretty well with modern phones.

So, just creating an app, that monitors the sky collecting light while charging the phone at night, that activates automatically, when plugged in to charge at night (e.g., when sensors say it's dark, battery is charging, and no significant accelerometer motion is detected, and Wi-Fi connection is used), could be used to record, compress and send astronomic data for a decentralized research of the skies. It could be run intensively, utilizing its compute and network, because at those times it would be plugged in to the grid and Wi-Fi.

The users could set up custom data servers to send the data to, and this way, collectively run night surveys. Who knows what they could discover? Undocumented satellites, UFOs, NEOs, and maybe something else that we didn't know of.

Well, most surveillance is now staring at people on the ground. We need to change our way of thinking. It is a good idea to let the phone monitor the sky at night.


[transiency] so, the surveillance cameras should point to skies, when idle? :)

Yes, it can use them more efficiently


No, no, surveillance cameras may need to monitor the ground all the time. But mobile phones do not work during the day and night. Moreover, people/phones sleep differently around the world for 24 hours, so if they monitor the sky while sleeping, there will be a 24-hour uninterrupted monitoring network covering the entire celestial sphere, which is too powerful!
