5 second power outage just turned 24 hours of science into 24 hours of wasted electricity. How can I prevent this? I would love some sort of battery backup, but how can I do this for all my computers scattered around the house?

Turn off write caching for the drive the BOINC data directory is located.
(Right click on Start icon -> Device manager -> Disk drives -> select your BOINC disk (double click) -> Policies tab -> Un-check (both) write caching option -> OK)

Either you should buy as many UPS as your computers, or make a secondary uninterruptable power line. None of this is cheap.

Can I move the BOINC directory to another drive? It's currently in my C drive and I don't want decreased performance.

You suggested this to me quite a while ago when I was having the same problem. So far it's worked and I haven't noticed any decreased performance either. Thanks again.

Yes. I use smallish SSD's for most of my systems but on my W10 system the Boinc Projects (app/project data) folder is on a HDD. Basically, cut and paste the Boinc directory to the second drive (maybe backing it up along the way) and reinstall Boinc, pointing to the new directory -> the secondary drive. The executable will still be on the primary drive but all the reading and writing will be done to the secondary drive. Obviously disable the caching on the secondary drive!

... and reinstall Boinc, pointing to the new directory ...
You don't need to reinstall BOINC, just:
0. Exit BOINC manager with stopping scientific applications, and move the BOINC folder from c:\ProgramData to its desired location. (On Windows XP from "c:\Documents and Settings\All Users\Application Data\" )
1. press Windows key + R, type regedit [enter] (it will open the registry editor which needs elevated privileges, so enable it)
2. press F3 (search), type boinc setup [enter]
3. It should find the first match at HKEY_LOCAL_MACHINE\SOFTWARE\Space Sciences Laboratory, U.C. Berkeley\BOINC Setup (you can also navigate to this key manually)
4. double click on the DATADIR entry, and edit the path to point to the new directory.
5. Restart BOINC manager.
