Suggestion: Lava cells into Obsidian

was thinking up alternate uses for lava cells (sorta like the water cell -> snowball thing) and thought up this:
Lava cell to obsidian in the compressor or maybe the extractor? Not really sure which would fit better.

Quote from I don't now

Try to craft Lava Cell+Lava Cell+Water Cell+Water Cell.

ah, nice, didn't know about that one.
