Bill's suggestion is a good one- using 2 layers of film with a fan.  This gives you more
energy conserved in heating than used to run the fan.

Another possibility is multi-layer polycarbonate panels.  They look like cardboard with
air spaces between 2 or 3 very thin layers of Plexiglas.  They last longer, but are more
expensive than film.  They work great on lean-tos and houses of the same design (shape)
as those designed for glass.  However, they're much lighter than glass and don't require
as heavy of a frame.
