There are fictional plot lines that involve using atmospheric/space noise as the methods for creating one time cypher pads for the ultimate in security. How much of that is based in reality is not known to me, but I know Tom Clancy used this type of encryption as a plot device.
For one time use cyphers or other non-realtime use, it seems like a good source. For realtime back and forth computer negotiating it seems to be much less useful.
