Subject: Back to 21st century, concrete

The 20th century has been the concrete century (particularly in
Japan). It has too been the century of the tropical rain forest
destruction in the hunt for hard woods. Near 2020 all that forest
will have been destroyed and another product will have to take
the place of hard wood. I think it will be a form of ceramic made
of presure molded concrete with some polymers. Such products
have been experimented, they behave as wood and have few
environment impact. The sooner they will be used the better.

Modular houses could be produced in factories with these products
driving down the housing cost by a factor up to 7.
