Yes, see geopolymers.

Because energy is still too cheap. Fracking methane will be
largely over by 2020, so expect renewed interest in low-energy

Oil is not really information-driven, the peak 2006 has hit them
cold. Peak total fossil and total nuclear fissible is 2020, almost 
nobody is aware of that yet.

2020 could be the sentinel event to the Fun of 2050.
