Hi
I'm the author of THE ORCHID GROWER, a juvenile science adventure novel, which was published in 2003. Recently I came back to it and was astonish to realize that as a matter of fact I have introduced independently the GPS technology with a simplified technical explanation since at the time I wasn't aware of the invention.

PROJECT TITLE: Zinc air batteries for affordable, renewable energy storage
GRADE LEVEL: High School - Grades 10-12
PROJECT DESCRIPTION: The primary objective of this project is to improve access of renewable energy to residents of developing states. Despite the rapid decline in price of photovoltaics, the overall cost is still high due to expensive storage technology. Zinc air batteries are excellent candidates for this purpose, but are limited by sluggish oxygen reactions. A self-assembled carbon aerogel made from carbon nanotubes and graphene can make rechargable zinc-air batteries more efficient. The resulting zinc-air batteries can form part of the solution to lowering the cost of renewable energy storage.

*******************************************************************
Claude Elwood Shannon (1916 – 2001) was an American mathematician, electrical engineer, and cryptographer known as "the father of information theory". Shannon was famous for having founded information theory with a landmark paper that he published in 1948. He is perhaps equally well known for founding both digital computer and digital circuit design theory in 1937, when, as a 21-year-old master's degree student at the Massachusetts Institute of Technology (MIT), he wrote his thesis demonstrating that electrical applications of Boolean algebra could construct any logical, numerical relationship. Shannon contributed to the field of cryptanalysis for national defense during World War II, including his basic work on codebreaking and secure telecommunications. (source:Wikipedia)
