@JRV you are right, this requires Windows Server 2012 or Windows 8 (or above). It also requires that PowerShell be started with admin rights. Thanks for pointing this out.
In Windows 7 and Windows Vista, it looks like you can get at the same information through the "Win32_EncryptableVolume" class in the "root\cimv2\Security\MicrosoftVolumeEncryption" namespace, but the code is not nearly as user-friendly as the new cmdlets in Windows 8.
