It can't work that way.  Power is force *times* motion.  You have a force
but no motion "while compressed", so therefore no power is being put into
the crystal and power can't be taken out continously.

Think about it.  If you could get power out of a crystal just because it is
compressed (not *being* compressed), you could clamp it in a vice and get
power indefinitely.

What you are looking for is called a "perpetual motion machine", "free
lunch", or "hogwash".
