A couple of weeks back, we pointed readers to "the unlikeliest beach book of the year:" David MacKay's Sustainable Energy - without the hot air.
Yesterday, this well-produced trailer for the book was passed along to us. Using a common 40-watt light bulb, MacKay provides a lucid demonstration of an individual's daily energy consumption. Touring the English countryside on his bicycle, the Cambridge physicist asks, and answers, what does the landscape look like when a country moves away from fossil fuels?
Good show, indeed.
