Surly and JD,
Here are the video links:

PS: Also in Energy efficiency 2 Amory points to a world shaking discovery that industrial engineers DO NOT WANT TO ADMIT. ALL the Industrial and Mechanical Engineering textbooks are WRONG on evaporative heat exchange coil design (massively, as far as energy efficiency is concerned ) BECAUSE the scientist that discovered how a gas OR liquid moves through a pipe or tube (how much FRICTION energy losses occur) in 1921 stated that the flow is TURBULENT, not LAMINAR. THAT is exactly backwards, as discovered by Amory Lovins! Do you know what that means? IT means EVERY pipe and pressure gradient friction factor in EVERY engine, pump, duct or pipe is DESIGNED for turbulent flow when it should be designed for laminar flow. This is a GIGANTIC (and very convenient for fossil fuelers!) WASTE of ENERGY! We are talking well over 60 to 70% REDUCTION in energy use just by redesigning ALL the above for laminar flow. This is because the HIGH friction losses will no longer occur and, WITHOUT REDUCING ANY OUTPUT OF WORK ENERGY, you reduce USE ENERGY by 60 to 70%.

Get Roamer to go through this stuff detail by detail. Maybe he will finally see what I've been trying to tell him for over a year, which he refuses to admit, about fossil fuels being UNNECESSARY to run our civilization. Since I'm NOT an engineer, maybe I can't get through to him. But Amory puts it all on the table. Amory MEASURES, putting instrumentation all over the place to get EXACTLY the accurate energy use picture without old, out of date, or just plain WRONG, engineering text book mantras about how much energy is used to do this, that or the other. This is REAL, Surly. Our imminent demise is nothing but a doomer's misplaced pessimism.
