Energy Density Quotes

Wind and solar power are land-intensive, a green sin, but not energy-dense, and affordable only when heavily subsidized. And wind power must be supplemented with hydrocarbons for reliability.

In the same way that when the car got going, people thought it would be an electric car, people thought it would be a steam car. Actually, the dark horse in that race was internal combustion, but because of the energy density of gasoline and discovery of oil in large amounts at that point in first Pennsylvania and then Texas, it won out over those other two, to the point that those other two are actually viewed as obscure footnotes in history.

One pound of uranium is worth about 3 million pounds worth of coal or oil.

All renewables, much as I love them, are diffuse. They all have a small power per unit area, and we have to live with that fact.

Spirit forgets that it's Spirit and condenses to a smaller version of itself, which is soul. Soul forgets that it's soul and condenses to mind. Mind forgets that it's mind and condenses to body. Body forgets that it's body and condenses to the lowest dimension that you can have, which is matter.

The daily grinding of evolution, as accelerated by technology, churns out more and more complex organisms, with higher rates of energy use, and with increasing specialization. Minds are the ideal way to express complexity, energy density, increasing specialization, expanding diversity -- all in one system. Mindedness is what evolution produces. Mindedness is what technology wants, too.

Eventually, when the universe expands enough, all that will be left is the dark energy.

A ten-times increase in the weight-oriented density of batteries would enable so many other moonshots, if we can find a great idea. We just haven't found one yet.

The dark energy is not exactly zero, but the first 122 decimal points are zero. That's crazy. That is really one of the craziest things we've ever discovered.

Cost, safety, energy density, rates of charge and discharge and cycle life are critical for battery-driven cars to be more widely adopted.
