gadolinium magnetic cooling

I noticed there was a new cooling/refridgerating technique. When do you think we'll see this kind of stuff in computers?

"As it passes through this field, the gadolinium in the wheel exhibits a large magnetocaloric effect—it heats up. After the gadolinium enters the field, water is circulated to draw the heat out of the metal. As the material leaves the magnetic field, it cools further as a result of the magnetocaloric effect. A second stream of water is then cooled by the gadolinium."

Hmmm.... magnetic fields and computers? I don't like the idea...

well, I'm saying that the HD doesn't emit a large EM field, while these cooling devices probably do, which would then muck up the HD...

Well, it's time to start switching to 3d optical storage anyway.
Didn't NASA have fun 3d storage machines?

But I don't think the magnetic fields from this cooling would matter much. They use permanent magnets. They usually don't disrupt HDDs and floppys that much.
