tldr: PVA is the window of the future, and it turns out that in additional literally anything else, we can also use highly bleached balsa wood to the point where infusing it with PVA makes it transparent enough. Slightly longer: also, PVA literally dissolves in water, so this is in fact an absolutely stupid idea unless you're also going to coat the resultant panes in chemicals that don't just act as water proofing but are also scratch proof. None of this is even remotely better than using actual glass.
