Solar power? Could enough energy be stored from indoor light to power the daily download? That's about the only improvement I can think of.

This uses 56µA for the DCDC alone. that means you would need at least 1mA for maybe an hour to just keep that going without any screen updates or communications. A windowsill setup might work but thats hardly "indoor" to me. This lasts 1 year on 2 AA rechargeables - just swap the batteries.
