Prof David MacKay on the Laws of Physics

Prof David Mackay FRS is Regius Professor of Engineering in the Department of Engineering at the University of Cambridge and chief scientific adviser to the UK Department of Energy and Climate Change.

He is also the author of  the famous (and free) "Sustainable Energy (Without the Hot Air)" . The whole book (12Megs) is available HERE

But he has also recorded a number of lectures on the viability and practicality of renewables, particularly he has focussed on the land areas needed to meet specific goals. These are goals that meet specific energy requirements. Here he is talking about systems that are other than window dressing or merely fashion statement technology.

My favourite quote is:- "I'm not anti renewables but I am pro arithmetic"

The recording is 18 minutes but is well worth a watch (unless you are a green dreamer that is)

Very interesting book - but it's a shame that a physicist does not seem to recognize the concept of entropy when applied to fuels for cars - equating kWhr of fossil fuel heat of combustion directly to kwHr of electricity for electric cars
