do you have a smoker or a grill that can be used as one?
if so, you can smoke dry jalapenos, which are then called chipotles. if not, you can either dry them in a dehydrator, or a low oven (around 200 degrees) for several hours.
finally, you can always pickle or freeze them. pickling is easy since it can be done in a water bath much like tomatoes. freezing works, but they will get a little mushy and then will need to be cooked in some way.
