![]() The message tree is a remarkable and creative idea, particularly in the context of the novel. The planet Lithia has virtually no naturally occurring metals on the surface and electrical power is extremely difficult to generate; how can you recreate electronic communications equipment? The answer lies in the piezoelectric effect.
This sort of message device also lent itself well to the story; the world of Lithia was one in which the biosphere was seen as important by the indigenous sapient life.
The piezoelectric effect was discovered by one of more of the Curies around 1880; it is the voltage produced between surfaces of a solid nonconducting substance (dielectric) when mechanical stress is applied. Comment/Join this discussion ( 0 ) | RSS/XML | Blog This | Additional
