The dark side of trust

The Economic Growth Engine: How Energy and Work Drive Material Prosperity
The authors of this unique book explore the fundamental relationship between thermodynamics (physical work)
and economics. They take a realistic approach to explaining the relationship between technological progress,
thermodynamic efficiency and economic growth, the findings of which conclude with a fundamental explanation of
endogenous growth that is both quantifiable and consistent with the laws of thermodynamics. A major implication of
this is that future economic growth is no
