During an unexpected one-day storm, years ago, several electronic items were destroyed in my house - causing a few thousand dollars worth of damage:
* Air compressor in my air conditioning unit
* Crock Pot
* Clothes washer
* Stereo system amplifier
* TiVo motherboard
There may have been other items damaged in the storm, but these are what were noticed as having worked before the storm, and did not work immediately after the storm. The sad thing is, this damage could have very easily been prevented.
Notice the distinct lack of computer-related devices in the list above?
