is it possible to make a cold (room temp) charged gas?
would be nifty to use in a heat pump. instead of using compressors you could use fields to compress and decompress the gas

Like, for example, the plasma within fluorescent bulbs?

i suppose that would work.
is there any reading material on using fields to compress cold plasma?

It's not exactly "reading material", but try holding a magnet up to a fluorescent tube, or one of those plasma globes you can egt at the novelty stores.

I would recomend a device you are not too fond of, since the palsma may never flow properly through it again (this from my own chilhood experience with a strong magnet and my family's first plasma screen TV!).

If you light one of those outside in Canadian Winter at -20 degC, the gas will probably remain below room temperature.
