I believe if you present the idea of “stockpiling” certain things in the event of a power outage etc. he may be receptive to it.
My wife came over to the “preppers side” gradually, but it didn’t really take her too long once I presented her with a list of events that had either happened to other people close to us at previous times. The ice storm in Quebec is also a great one to use as people were without power for a long time. The recent super storm Sandy on the east coast of the USA is another one that you could use for an example.
I also suggest that you don’t try to drop him in the deep end of prepping all at once but rather get him to dip his toe in and slowly work up to his whole foot, leg, torso etc.
Slow and steady wins the race.

Best of luck.

As the bird is the stone. What kind of man is he?
Does he likes outdoors? (a lot of prepping can be done with the "excuse" of outdoor activities)
Have you lived thru an emergency (even if a short one)? (is yes, then start preparing for those emergencies first)
Does he like to cook? (cooking without electricity is a nice trick for some cooks to learn"
Does he like shooting sports? (some introduction to prepping can be done with the "excuse" of security)
How old is he? (if old enough he may remember some "emergencies" and you could try to relate him to some of them)
etc.

Time and subtle hints. My wife came to the prepper side slowly as well.

My advice:
Resist the urge to direct, focus, or otherwise critique anything your spouse does that he or she wants to do with respect to prepping. Nothing will quench the desire to get involved faster than someone else trying to manage you. My wife doesn't prep the way I do, but that doesn't mean her efforts are any less valuable. Gerardo brings up the good point of expanding on interests your husband has already. Remember though that prepping is first and foremost a state of mind, not a state of storage. I believe the main reason people don't prep is because of fear. Why? Because to prep is to acknowledge that things can (and do) happen that fall well outside of our nice, normal biases (look up the normal bias syndrome sometime). Men don't express or deal with fear very well. Most often, we hide our fear with anger or dismissal. That doesn't mean it's not there. A better response is to accept that we are (or would be) afraid if something were to happen.
Since no one likes to be afraid, we can think of things we can do that would make us less vulnerable and more prepared. Where the mind goes, the body will follow.

You know what I did I turned the power off at the breaker and said the power went out and said to her now what do you do
Ever since she's into more than I am sometimes

For us it was a slow process. Mine thought I was insane and there were alot of arguments and pity filled looks, both ways. After my initial "panic period" when I thought the world was out to get me, once I slowed down and took a breather, I learned how to work him better. I showed him news of train derailments, and storm aftermath (like Sandy as an example) and asked him what would we do?
I also rewarded him when he brought me prepper type things rather then the normal girly things. Needless to say I never get flowers, not that I liked that even before, but now a lantern bought on sale makes a happy wife, thus a happy life.
This is key. Don't ask for too much, don't freak out with him knowing, and don't try to spend all your savings on prep supplies. Do the learning on your own and ask for small things instead of the things you might usually ask for (example above with the flowers).
Let him take his time to come around. Forcing the issue causes fights which sucks. Also allow him input into your thinking and plans. I thought mine was an idiot for not agreeing totally with my opinion du jour but given time I realized that he is quite smart and maybe that radio host isn't omnipotent.
Sometimes they can bring something unexpected to the table that you will appreciate.
I hope my misery can help you avoid some of those frustrating nights. Good luck!!
