Yes. Impervious to EMP.
If you were going to use them as backup generators, they should be able to survive an EMP event.

Well, no; although some TEMPEST implementations provide shielding against EMP. TEMPEST stands for Telecommunications Electronics Materials Protected from Emanating Spurious Transmissions. It's all about preventing eavesdropping on leaking electronic emanations.

No. That is not Tempest. Not in the slightest. Don’t believe everything you read on the Internet. Most of it is written by underachieving morons.
