Can anyone speak to the potential battery drain from this thing? Sounds like a wicked idea though. Like a more modern seti@home.

From the paper: The application runs when the phone is not in active use. It launches itself when it detects a power source, and quits when the power is disconnected. No additional light shielding, such as tape, of the camera is required, other than placing the phone face-up (camera-down) on a table. In this way, no active participation is required once the application is installed and its operation should be fairly inobtrusive, which is critical to achieving wide participation in the smartphone community. To address user security concerns, no frames will be stored or up- loaded if the average pixel response value over the frame exceeds a threshold, such that full images cannot be re- constructed offline. [snip] Note that this assumes continuous operation; some degradation of observational power is expected, as phones will typically join the network during night-time charging. The observational power of such a network clearly hinges on the level of user adoption and continued participation. -- This makes sense, there's no need to operate during the day; in fact it's much better to operate at night when background light (and therefore noise) is likely to be lower. Cosmic rays don't sleep.

Actually, HTC has an application that you can run on your phone that can contribute to any BOINC projects, while the phone has its screen off and is charging - that includes helping Seti@Home. I have it on my phone so I contribute 8-10 hours of calculations to projects every single day when I go to sleep.

  For the broader context: The Android app (BOINC, https://play.google.com/store/apps/details?id=edu.berkeley.boinc https://play.google.com/store/apps/details?id=edu.berkeley.b...) that allows you to run SETI@Home on your Android device will also let you to support other volunteer distributed computing projects. The projects are from various fields of science like Einstein@Home (astrophysics), PrimeGrid (mathematics), or World Community Grid (humanitarian projects).

    This is the HTC app I talked about: https://play.google.com/store/apps/details?id=com.htc.ptg https://play.google.com/store/apps/details?id=com.htc.ptg I am not sure what is different between this and the official BOINC app, apart from a sleeker interface. Both do the same thing.

It is only activated when it is plugged into a power source.
