 Energy Needed to Power Civilization

The numerical results of my calculations show that the quantities of energy required for permanent survival and communication are surprisingly modest. For a society with the same complexity as the present human society on Earth, starting from the present time and continuing forever, the total reserve of energy required is about equal to the energy now radiated by the Sun in eight hours. The total energy reserve contained in the Sun would be sufficient to support forever a society with a compl...

 The Problem of Energy

As a child, I read Friday by Robert A Heinlein, which portrayed a future in which energy needs are addressed by energy storage devices called "Shipstones", which are described as a way to pack more kilowatt-hours into a smaller space and a smaller mass than any other engineer had ever dreamed of. To call it an "improved storage battery" (as some early accounts did) is like calling an H-bomb an "improved firecracker." In the novel, the Shipstone's eponymous inventor realised "that the problem...

Isn't that is isn't plentiful. The sky is raining energy. It's that we have to collect it into buckets for use.

These are partial direct quotes, the direct quote is from a hacker news comment.

 The Physics of Fusion

The basic physics of thermonuclear energy is seductively simple. Fission produces energy by atomic fracture, fusion by tiny acts of atomic union. Every atom contains at least one proton, and all protons are positively charged, which means that they repel one another, like identical ends of a magnet. As protons are forced closer together, their electromagnetic opposition grows stronger. If electromagnetism were the only force in nature, the universe might exist only as single-proton hydrogen a...

 The ITER Project

Years from now—maybe in a decade, maybe sooner—if all goes according to plan, the most complex machine ever built will be switched on in an Alpine forest in the South of France. The machine, called the International Thermonuclear Experimental Reactor, or iter, will stand a hundred feet tall, and it will weigh twenty-three thousand tons—more than twice the weight of the Eiffel Tower. At its core, densely packed high-precision equipment will encase a cavernous vacuum chamber, in which a s...

 Cosmic Accounting

Only cosmic costing accounts for the entirely interdependent electrochemical and ecological relationships of Earth's biological evolution and cosmic intertransformative regeneration in general. Cosmic costing accounts as well for the parts played gravitationally and radiationally in the totality within which our minuscule planet Earth and its minuscule star the Sun are interfunctionally secreted. Cosmic costing makes utterly ludicrous the selfish and fearfully contrived "wealth" games being r...

 Fire is Unwinding the Sun's Energy from the Trees

Nobody is bom a specialist. Every child is born with comprehensive interests, asking the most comprehensively logical and relevant questions. Pointing to the logs burning in the fireplace, one child asked me, "What is fire?" I answered, "Fire is the Sun unwinding from the tree's log. The Earth revolves and the trees revolve as the radiation from the Sun's flame reaches the revolving planet Earth. By photosynthesis the green buds and leaves of the tree convert that Sun radiation into hydrocarb...

Every year the trees store the sun's energy in a ring. When we burn the tree, we are unwrapping that energy.

 How the Computer Will See the World

We find all the no-life-support-wealth-producing people going to their 1980 jobs in their cars or buses, spending trillions of dollars' worth of pe¬ troleum daily to get to their no-wealth-producing jobs. It doesn't take a computer to tell you that it will save both Universe and humanity trillions of dollars a day to pay them handsomely to stay at home. History's political and economic power structures have always fearfully abhorred "idle people" as potential troublemakers. Yet nature neve...

 The Energy Efficiency of Spheres

Environment-controlling buildings gain or lose their energy as "heat o cool" only through their containing surfaces. Spheres contain the most vololume with the least surface—i.e., have the least possible surface-to-volume ratio. Every time we double the diameter of a spherical structure, we in¬ crease its contained atmosphere eightfold and its enclosing surface onlyily fourfold. When doubling the diameter of our sphere, we are not changiring the size of the contained molecules of atmospher...

 The Critical Path

H UMANITY IS MOVING EVER DEEPER into crisis—a crisis without prec¬ edent. av upon completely transforming omnidisintegrated humanity from a complex of around-the-world, remotely-deployed-from-one-another, differently col¬ ored, differently credoed, differently cultured, differently communicating, and differently competing entities into a completely integrated, comprehensively interconsiderate, harmonious whole. Second, we are in an unprecedented crisis because cosmic evolution is also...

 The Chemical Decline in Energy

It is the destiny of wine to be drunk, and it is the destiny of glucose to be oxidized. But it was not oxidized immediately: its drinker kept it in his liver for more than a week, well curled up and tranquil, as a reserve aliment for a sudden effort; an effort that he was forced to make the following Sunday, pursuing a bolting horse. Farewell to the hexagonal structure: in the space of a few instants the skein was unwound and became glucose again, and this was dragged by the bloodstream all t...
