I've often wondered about how much power it would take to run a wireless SD card (enough to be solar powered?) and how the software could be extended to allow uploads.

That's a pretty interesting idea. It would be easy to power them via solar. I couldn't find power specs for WiFi cards but it seems typical SD cards run on 3.3V up to 300mW, but newer high speed cards can draw up to 3W. A small panel could easily handle that.
