Does a Snickers bar (60g = 293 kcal) provide enough energy to climb from Zermatt (elevation 1660m) to the top?
Does a Snickers bar (60g = 293 kcal) provide enough energy to climb from Zermatt (elevation 1660m) to the top of the Matterhorn (4478m) or might you need to stop at Hirnli Hit (3260m) to eat another one?
You and your gear have a mass of 75kg and all the work is done against gravity (that is, you are climbing straight up!). Also assume that the human body converts chemical energy to external work at 100% efficiency (which of course it doesn’t!).
# Work (J) = mass (kg) x g (m/sec2) x height gained (m)
# g = acceleration due to gravity (9.8 m/sec2)
# 1 Joule is 1 kg m2 / sec2 and 4.18 J = 1 kcal
if that’s all you care about…60 grams; 230 calories…you have no business being in Switzerland, let alone Zermatt. I’ll bet you even DROVE in Zermatt. (inside joke. You CAN’T drive in Zermatt. Now ask me why)
this is science for you. It reduces an experience of awesome beauty and majesty to some officious little exercise in how to be a complete robot.

Operation and Control of Electric Energy Processing Systems $88.95 Explains the fundamental issues related to control, communications, and social aspects of large-scale electric energy processing systemsFocusing on the dynamic modeling and control of interdependent communications and electric energy systems, micro-electro-mechanical systems (MEMS), and the interdisciplinary education component of the EPNES (Electric Power Networks Efficiency and Security) initiative, Operation and Control of Electric Energy Processing Systems provides a working knowledge of, as well as cutting-edge developments in, electric power systems theory and applications.The book begins with an introduction to the EPNES initiative, and then investigates several dynamical models in fault tolerant operation and control of energy processing systems. Intelligent power routers for distributed coordination of electric energy processing networks are developed. Next, the book addresses the design of power circuit breakers, using an array of small MEMS switches together with diodes for faster operation and smaller equipment size aimed at reducing the vulnerability of a power system to faults.A GIS-based market simulation studies for power systems education is then developed. Finally, the book employs a social-sciences approach to help understand the development and use of distributed generation technologies—small-scale generators that produce power near their loads—in the electric power system.Operation and Control of Electric Energy Processing Systems can be used both as a book for teaching graduate courses and as a handbook that provides state-of-the-art knowledge to engineers and researchers working worldwide in interdisciplinary areas such as control, power systems, economics, environment, and social sciences. It will also appeal to policy makers as well as executives and engineers of electric utilities. |
