Can We Have Unlimited Power? [electronic resource]: A History of Energy

Due to population, technology, and other factors, the emerging global generation is the most power-hungry that has ever lived. This program reveals how energy is harnessed today from wind, the sun, and the heart of the atom, and how these sources might be further utilized in years to come. Viewers learn how, in past centuries, the drive for new sources of power was linked to profit, with ideas and inventions creating fortunes and shaping the course of history. The film also shows how an awareness of the basic nature of energy has historically lagged behind our knowledge of what it can do.

Cool [electronic resource]

Cooling is more than a luxury - nowadays it's a necessity. Without refrigerated shipping and stocking, fresh food wouldn't reach our supermarkets so easily. Can you imagine living without it? Air-conditioning, on the other hand, was invented as a means to control the humidity that was ruining the paper of printing offices, rather than as the technology we now use to cool off. This program discovers that you can't create cold; you can only "move" temperature from one place to another. Learn how early refrigeration units used all sorts of chemicals that were harmful to the environment - and how new technology may provide a solution: cooling via the vibrations of sound. That does sound cool.

TEDTalks [electronic resource]: Dan Cobley - What Physics Taught Me About Marketing

Physics and marketing don't seem to have much in common, but Dan Cobley is passionate about both.
