ABSTRACT

One of the greatest challenges in the history of human civilization involves capturing and securing useful energy. Access to these energy sources can be related directly to the rise and fall of several of the world’s most successful civilizations.1 Over time, society has become reliant on fossil fuels to maintain its industrial economy with little use of nuclear power or renewable energy sources.1 Successful advancements
