 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.

 Heat is a Substance

We recognize in the concept of heat which appears here a similarity to other physical concepts. Heat is, according to our view, a substance, such as mass in mechanics. Its quantity may change or not, like money put aside in a safe or spent. The amount of money in a safe will remain unchanged so long as the safe remains locked, and so will the amounts of mass and heat in an isolated body. The ideal thermos flask is analogous to such a safe. Furthermore, just as the mass of an iso- lat...

Like mass. It is a quantity.

 The Strategy of Releasing All Data

The response many organizations adopted then (and continue to pursue AF) is to provide overwhelming amounts of data to the public. This provided a two-fold defense. First, it allowed immediate deniability to any charge of withholding data. Second, the sheer volume of data available meant that almost any argument could be made or refuted with selective referencing and correlation to other publicly available information. This is a rapid, cheap response that puts the onus back on the accuser to ...

Interesting idea: be completely transparent, releasing so much data that any hypothesis can be cherry-picked from it, then hire spin-doctors to do just that.

 The Brain Consumes Lactose During Exercise

Scientists have discovered that lactose, a byproduct of intense muscular activities, can be used to fuel the brain with energy. When glucose, the natural fuel of the brain, is no longer present in sufficient quantities, the cell tissue can “switch” to alternative energy, to prevent any damage to the brain on account of the lack of energy. [...] Consequently, by consuming the lactose in the blood, the brain clears the way for glucose, the main powering substance in the body, to reach the...

This frees up the body's glucose to fuel the muscles in times of high energy demands on the body (Note: This meme must be wrong in using the term "lactose," because that is a sugar that comes from milk. "Lactate" is a byproduct of muscles consuming glucose that fuels the brain while the muscles take energy-precedence).

 Truth in Minute Ammounts

The universe flows, carrying with it milky ways and worlds, Gondwanas and Eurasias, inconsistent visions and clumsy systems. But the good conceptual models, these serena templa of intelligence on which several masters have worked, never disappear entirely. They are the great legacy of the past. They linger under more and more harmonious forms and actually never cease to grow. They bring solace by the great art that is inseparable from them. Their permanence relies on the immortal poetry of tr...
