THE HISTORY of man is a record of progress directly tied to a continuing reduction in the cost of energy. From the discovery of fire and the wheel, to the harnessing of coal, oil, and natural gas for the generation of electricity, man’s material lot has improved in direct proportion to the cost and availability of energy.
Now that fossil fuels have reversed their curve of cost efficiency, and other sources of energy (winds, tides, solar energy, fission, geothermal and hydroelectric power) have become economically attractive only in comparison to the ever-increasing cost of fossil fuels, we must look to what is the cheapest source of future energy in our universe—fusion.
