A balanced introduction to tomorrow's energy sources Over the course of the next fifty years, there will be a shift in the quest for sustainble energy, including a major change in transportation from internal combustion engines burning petroleum-derived fuels to newer technology engines using new transportation fuels. Alternative Energy Reources examines our options for energy sources with a focus on hydrogen as a large-scale, secondary energy vector parallel to electricity. As the price of petroleum products increases, the world is scrambling to find a suitable replacement energy source. In this comprehensive primer, Professor Paul Kruger examines energy use throughout history and the exponential expansion of our energy use beginning with the Industrial Revolution through the present day. The book then analyzes the various alternative energy sources available, including renewable energy (hydroelectric, solar, wind, biomass, and geothermal), nuclear, and hydrogen. He addresses each energy source's pros and cons based on our needs, availability, and environmental impact aspects. Finally, Dr. Kruger proposes the use of hydrogen as a fuel to sustain our energy supply produced by appropriate technology mixtures of renewable and nuclear energy.

A very special book about a determined little turtle who learns to complete his goal by never giving up. It's an urban tale, beautifully illustrated to the backdrop on New York City's Central Park. A great way to learn about animals and a message to children that if you follow a path, and stick with it, through hardship and doubt, then you'll be amazed at what can be achieved. The Central Park Turtle was written and illustrated by NYC born and raised, fallen tree artist Paul Kruger. The visuals were created from panoramic photos of the Central Park Reservoir. Illustrations and graphic elements were then overlaid and drawn on top of them to give an authentic view of the actual path. To learn more, visit centralparkturtle.com
