In Powering the Future
, Nobel laureate Robert B. Laughlin transports us two centuries into the future, when weve ceased to use carbon from the groundeither because humans have banned carbon burning or because fuel has simply run out. Boldly, Laughlin predicts no earth-shattering transformations will have taken place. Six generations from now, there will still be soccer moms, shopping malls, and business trips. Firesides will still be snug and warm.
How will we do it? Not by discovering a magic bullet to slay our energy problems, but through a slew of fascinating technologies, drawing on wind, water, and fire. Powering the Future is an objective yet optimistic tour through alternative fuel sources, set in a world where weve burned every last drop of petroleum and every last shovelful of coal.
Fossil fuels will run out. The present flow of crude oil out of the ground equals in one day the average flow of the Mississippi River past New Orleans in thirteen minutes. If you add the energy equivalents of gas and coal, its thirty-six minutes. At the present rate of consumption, well be out of fossil fuels in two centuries time.
We always choose the cheapest gas. From the nineteenth-century consolidation of the oil business to the California energy crisis of 2000-2001, the energy business has shown, time and again, how low prices dominate market share. Market forcesnot green technologywill be the driver of energy innovation in the next 200 years.
The laws of physics remain fixed. Energy will still be conserved, degrade entropically with use, and have to be disposed of as waste heat into outer space. How much energy a fuel can pack away in a given space is fixed by quantum mechanicsand if we want to keep flying jet planes, we will need carbon-based fuels.
Animal waste.If dried and burned, the worlds agricultural manure would supply about one-third as much energy as all the coal we presently consume.
Trash. The United States disposes of 88 million tons of carbon in its trash per year. While the incineration of waste trash is not enough to contribute meaningfully to the global demand for energy, it will constrain fuel prices by providing a cheap supply of carbon.
Solar energy.The power used to light all the cities around the world is only one-millionth of the total power of sunlight pouring down on earths daytime side. And the amount of hydropump storage required to store the worlds daily electrical surge is equal to only eight times the volume of Lake Mead.
