What about using METHANE? it is 1/2 the weight of air and a 1000 cubic foot would lift 15kg.

At about 4$ per 1000 cubic feet and readily available about any region of the US. I live in Pennsylvania where they now cap wells instead of producing until the price goes back up.

Is it too explosive? I know it does not have as much lift as Helium but just make the envelopes larger or maybe less thick (methane does not leak)?

Sorry If I am off topic but I remember as a kid producing methane just to inflate balloons ....that was after I tried to produce hydrogen and founding out how explosive it was.
