Such (ancient) technologies plus state-of-the-art computing and communication systems is prime material for science fiction novels about highly advanced civilizations.

I think we should strive towards that - use the wisdom of our ancestors to build zero-energy systems, powered by naturally occurring energy, controlled and enhanced by computers.

There are lots and lots of things that have already been invented in the past, we should just listen to our grand grandparents a bit closer.. After all, they built them for future generations, including us..

I'd add nature to that 'list'. There's so much we can - and have - learned from what sometimes appear to be dumb or primitive processes.
