Bury Charcoal to Mitigate Climate Change 

Reading "Just Cool It!" by Suzuki and Hanington introduced me to the ancient terra preta agricultural technology, given as a possible solution, or part of the solution, to the global warming problem. The term is apparently Portuguese for "black earth" and the technology involves enriching the soil by ploughing it full of charcoal. Suzuki and Hanington make the point that this should sequester a lot of carbon in the soil, thereby taking it out of the atmosphere. Charcoal is nearly pure carbon. Moreover, charcoal, being indigestible to decay organisms, should stay in the soil for a very long time. The logical raw material for making the charcoal would be either wood from clearing the land for agriculture, or crop residues, the parts of the crop plant that people cannot eat.

Making Charcoal at Scale

In modern pyrolysis plants, not only is charcoal produced, but also flammable off-gasses, which could be used for fuel directly in some future scenario, or catalytically reformed to a liquid fuel for running the tractors and combines. In gaseous form, the fuel could run a steam turbine to produce electricity to supplement that from wind farms, hydro, tidal, geothermal, thorium-nuclear, and photovoltaics.

However, the off-gasses are also used to fuel the pyrolysis plant itself. Whether any would be left over for other uses would depend on careful plant design for energy efficiency and on avoiding fuelled drying operations. Thus, the feedstock should be sun-dried.

Competing Schemes 

Schemes like second-generation power ethanol are touted as carbon-neutral, but in terra preta with these additions, we have one that is actually carbon-negative.

Unintended Consequences 

However, the soil ends up black. No other color is as efficient at converting sunlight into heat, which we don't need more of at this point. This seems to be a problem with the terra preta solution. (The ideal color for avoiding heat production would be white.)

Mitigation

The use of any terrestrial artificial mirror membrane to pull the average reflectivity of the earth back up after terra preta implementation has the drawback that the membrane will get dirty rapidly from dust, pollen, and plant parts, thereby reducing its efficiency. (Commercial photovoltaics have the same problem.) Orbiting space mirrors have also been proposed as the solution to global warming but maintenance would be an issue there also; even in space, there are high-velocity particles that can cause wear and tear over time

However, a living means of light reflection, like a low understory of predominantly white plants (e.g., lamb’s ear, dusty miller, or bugleweed), would renew itself, gratis, each year. Plants on land have always had the problem of keeping their leaves clean and by now natural solutions will have evolved (Photovoltaics manufacturers, take note).

An alternative mitigation would be to set aside a portion of the crop residues with which to cover the soil for improved light reflectivity. If these residues are left on the field over the winter, they might become snow-bleached in the spring when the snow melts, which releases the bleaching agent ozone. This would further improve the reflectivity of the fields.

#30. The Russian-dolls--multiverse Part II [physics]

PH

Red, theory; black, fact



Continuing from the previous post, leptons may arise as electromagnetic wave functions originating in p2 that are transported into our p3 universe/condensate by ordinary diffusion and convection. Wave functions in p2 that are already leptons become our baryons when they are transported in. The only kind of wave functions that are "native" to a given frame of reference are electromagnetic (photonic) in that frame of reference. If they subsequently propagate towards increasing p (inwards) they gain mass as matter; if they propagate towards decreasing p (outwards), they first lose mass as matter until they are photonic (i.e., massless) and then gain mass as antimatter.

To produce stable leptons from in-migrating photons, the first condensates, the p2s, would have had to be rotating simultaneously about three mutually perpendicular axes. If this is impossible for p3 physics, we have to appeal to the possibility of a different physics in p1 for any of these ideas to make sense.

A "universe" is something like an artist's canvas with a painting in progress on it. First, nature makes the blank canvas, and then, in a second stage, puts the information content on it. Consider the moon. It formed out of orbiting molten spray from the collision of two similarly-sized planetesimals. In the molten state, its self-gravity could easily round it up into a perfect sphere which could have solidified with a mostly smooth surface. Call this smooth surface the "canvas." Subsequently, the very same force of gravity would have brought down meteors to cover the surface in an elaborate pattern of craters. Call this the "painting." 

Now consider the neutronium core of a neutron star, viewed as a p4, or small universe. The tremendous energy release of the catastrophic gravitational collapse in which it forms homogenizes all the matter into pure neutrons, thought to be a superfluid. This creates the "canvas." Subsequently, matter and energy from our p3 migrate into the superfluid, producing a "painting" of leptons (our photons), baryons (our leptons), and "uberbaryons" (our baryons). Indeed, the neutron-star core is actually thought to be not pure neutronium, but neutronium containing a sprinkling of free protons and electrons (as seen in p3, of course).

#29. The Russian-dolls--multiverse Part I [physics]


Red, theory; black, fact

A Matryoshka

The space we live in may have an absolute frame of reference, as Newton taught, and which Einstein taught against. This frame of reference may be a condensate, like the water a fish swims in.

The divide-and-conquer strategy that has served science so well thus far can continue with the conceptual disassembly of this space into its constituent particles. The question arises if these particles are situated in yet another space, older and larger than ours, or if we go direct to spacelessness, where entities have to be treated like Platonic forms. In the former case, does that older, larger space in turn comes apart into particles situated in a still older and larger, etc, etc, ad infinitum?

Infinities are the death of theories. Nevertheless, let us continue with the Russian-dolls idea, merely assuming that the nesting sequence is not infinite and will not be infinite until the entire multi verse is infinitely old, because the "dolls" form one by one, by ordinary gravitational collapse, from the outside in.

Wave functions would be the basic building blocks, following quantum mechanics. In the outermost space, previously called #, the wave crests always move at exactly the speed of light.

This speed is not necessarily our speed of light, c, but more likely some vastly greater value.

The space-forming particles of # are themselves aggregates with enough internal entropy to represent integers and enough secondary valences to form links to a set of nearest neighbors to produce a network that is a space. This space acts like a cellular automaton, with signals passing over the links to change the values of the stored integers in some orderly way. The wave functions are the stereotyped, stable figures that spontaneously develop in the automaton out of the initial noise mass left over from catastrophic gravitational collapse. 

The dimensionality of a space would increase steadily over time, because the number of links emanating from each node in the underlying network increases slowly but surely. Macroscopically, this dimensionality increase could look something like protein folding. 

Let us label the Russian-dolls universes from the outside in, in the sequence 1, 2, 3,...etc, and call this number the "pupacity" of a given frame of reference. (From the Latin "pupa," meaning "doll.") Let us further shorten "pupacity" to "p" for symbol-compounding purposes. Thus, the consecutively labelled spaces can be referred to as p1 (formerly "#"), p2, p3,... etc.

pn can exhibit global motions ("n" is some arbitrary pupacity), such as rotation, in the frame of reference of p(n-1): a whole universe rotating as a rigid unit. Probably, it can drift and vibrate as well.

Global motions must be subtracted from the true, outer, speed-of-light speed of the wave crest to produce its apparent speed and direction when seen from within pn. Thus, the universe's love of spinning and orbiting systems of all sizes is explained: a spinning, global-motion vector is being subtracted from the non-spinning, outermost one. As the pupacity of the frame of reference increases, more and more of these global vectors are being subtracted, causing the residual apparent motion to get progressively smaller. We would assume under current physics that the wave functions are acquiring more and more mass, to make them go slower and slower, but mass is just a fiction in this scenario. However, the reliance of current physics on the mass construct is an opportunity to determine the pupacity of planet Earth: it is three.

Three, because physics describes three broad categories of particle mass: the photon, leptons, and baryons. The photon would be native to p1, leptons, such as electrons and positrons, would be native to p2, and baryons, such as protons and neutrons, would be native to p3, our own sub-world. 

The positron atom would be a standing-wave pattern made up of oppositely rotating wave functions, an electron and a positron, both native to p2. A neutron would be exactly the same thing, but native to p3.
