As with all so called neat inventions scaling up is the challenge and usually impossible

I could see this for uses in quiet or small spaces cooling. Laptops, servers and other cramped electronics come to mind.

My home computer has a CPU fan that recently died. PC still works but I have to be careful regarding the temp. I would imagine that such a cooling would be able to last longer.

If necessity is the mother of invention....why are so many unnecessary things invented?

I built a hovercraft (kind of) 20 years ago out of balsa, aluminum foil and an neon sign transformer. It hovered but you had a cable dragging below. They are going to need a Mr. Fusion to power this thing.

A few thousand miles of electrical extension cord and wallah!

Seriously for a sec...

I’m waiting for the first case of ion poisoning.

It's that small percentage of neat inventions, where somebody figures out how to actually scale it up to useful size, range, etc, and at a cost-effective price, which make the inventor rich.

Does that apply to cold fusion? /s
