Get started for freeUse the two rule-of-thumb approaches (by mass and by cost) to estimate the energy investment in a laptop computer, whose mass is \(1.4 \mathrm{~kg}\) and cost is \(\$ 1,300\). If the estimates are strikingly different, which do you suspect is more representative of the truth?
Try constructing a statement that communicates the grave risk we create for ourselves as we flirt with potential collapse without being too off-putting or unjustifiably certain.
Try crafting a diplomatic and persuasive response to someone who says that the problem with your story - concerning possible bad outcomes-is that it's a real downer and lacks a message of hope.
List three professions around today that will be very unlikely to exist if we revert to a lower energy/resource, less high-tech state.
Use the two rule-of-thumb approaches (by mass and by cost) to estimate the energy investment in a farm tractor, whose mass is \(2,400 \mathrm{~kg}\) and cost is \(\$ 25,000\). If the results are even within a factor-of-two of each other, we can conclude that the estimate is probably pretty decent as a rough guide.
