Solar Power Even At Night

Liquid salt, it turns out, has some interesting applications in the field of energy power plants.

Today, lets look at two methods that use liquid salt.

The first one is a solar thermal power plant in Spain, a power plant that gets around one weakness of solar power, which is, that the Sun is not always visible due to weather, and it is not available at night.

There is a salty solution to that problem:

"It is the first station in the world that works 24 hours a day, a solar power station that works day and night!" said Santago Arias, technical director of Torresol Energy, which runs the station.

The mechanism is "very easy to explain," he said: the panels reflect the suns rays on to the tower, transmitting energy at an intensity 1,000 times higher than that of the sun's rays reaching the earth.

Energy is stored in a vat filled with molten salts at a temperature of more than 500 degrees C (930 F). Those salts are used to produce steam to turn the turbines and produce electricity.

It is the station's capacity to store energy that makes Gemasolar so different because it allows the plant to transmit power during the night, relying on energy it has accumulated during the day.

"I use that energy as I see fit, and not as the sun dictates," Arias explained.

(Solar Power Even At Night).Imagine a smart power grid built with these liquid salt storage facilities all along it.

As power needs fluctuate downward, energy going into the grid, whether solar thermal, solar photo-voltaic, wind, and other methods, is stored for later use when the fluctuation goes upward again.

Another place liquid salt is used for power generation has been around for quite a while.

The administrator of Oak Ridge National Laboratory, top physicist Alvin M. Weinberg, wanted a Thorium Molten-Salt Reactor (MSR), but was fired by Nixon for advocating MSR.

Nuclear Concerns

We have a lot of material concerning Japan's Fukushima nuclear plants (The Fukushima Coverup).

Since those type of nuclear plants are having aging problems in America, we must ask "is Fukushima coming to a location near you?"


The USA is not immune from this type of catastrophe:

Putting A Face On Machine Mutation - 2

When we speak of "life" or "the cosmos", starting our discussion at "the beginning" is difficult.

Especially when, in some ways, "the beginning" is as illusive to us as defining or grasping the meaning of "a line."

Wikipedia tells us that "a line" can extend to infinity, in either direction, having no beginning, and no end.

Or "a line" can be finite in both directions, having one point described as the "beginning point", with another point being described as the "end point".

Still, those two points exist on that other "line" which, as I said, has no beginning point and no end point.

Interestingly, "a line segment" has the same property as one type of line, that is, it has both a beginning point and an end point.

When a beginning point exists, but no end point exists, then the entity is not called "a line segment" or "a line", instead it is called "a ray."

In the first post of this series we dealt with "the beginning", in the sense that plane geometry deals with it, i.e., somewhat like the discussion of "a line."

We looked at where life begins, not in the sense of time, not in the sense of the past or future, but in the sense of locus, that is, where in terms of location, does the "machine" world end, and the world of "life" begin?

To be sure, in this series we have set forth a valid reason to equate "machine" with "inorganic", likewise to equate "life" with "organic":

"Our cells, and the cells of all organisms, are composed of molecular machines. These machines are built of component parts, each of which contributes a partial function or structural element to the machine. How such sophisticated, multi-component machines could evolve has been somewhat mysterious, and highly controversial." Professor Lithgow said.
...
"François Jacob described evolution as a tinkerer, cobbling together proteins of one function to yield more complex machines capable of new functions." Professor Lithgow said.

"Our work describes a perfect example of Jacob's proposition, and shows that Darwin's theory of evolution beautifully explains how molecular machines came to be."

(ibid, quoting Science Daily and Monash Univ.). Our science describes those "component parts" of molecules with the word "atoms", which are said to be the smallest unique identifier of  what our science calls "the elements."

What we call "simple cells" are said to be complex molecular machines (inorganic) with something more, hence, more complex organization (organic).

Thus, in this context when we ask about "the beginning", we are simply asking "when we use super microscopes and/or other tools for looking deep into the micro world which our eyes alone cannot detect, where does the 'machine' essence end, and where does the 'organic' essence begin?"

In some cases the answer to that question will depend on definition, on nomenclature.

It probably behooves us to substitute "boundary" in place of "beginning", when we discuss "machine" or "life", at least in the context of locus.

So, concerning inorganic machine entities compared with organic life, our nomenclature should change as scientific discoveries improve to bring us results that boil down to a better scientific understanding.

Einstein once said: "Make everything as simple as possible, but not simpler" (paraphrased "don't oversimplify").

Based upon the statements of Professor Lithgow, above, we can define two categories of entities, machine (inorganic) and life (inorganic bound with organic).

In that sense, all plants, animals, and elements are either "machine" or "life", it is just that "life" in this nomenclature is "machines bound to additional organic essence", and "machine" in this nomenclature is "atoms and/or molecules without organic essence", or as a recent comment by a scientists indicates:

Dr Clarke said: “There are a lot of fundamental questions about the origins of life and many people think they are questions about biology. But for life to have evolved, you have to have a moment when non-living things become living – everything up to that point is chemistry."

(Univ. of York, cf Organic & Biomolecular Chemistry). So, for purposes of this discussion, looking into our super microscope at the lowest level of the machine world, we will see atoms, then moving up a level we will see atoms organized into molecules, then moving up another level we will see very complex molecules, then at the level where we approach the boundary between machines and where life begins, we will see a very complex molecular machine with something more, something that transforms it into life, a super complex machine with super organization, something we call organic, then eventually we reach the level of "a cell" (cf. Are Toxins of Power Machines Or Organisms?).

Leaving the concept of boundaries, now turning to concepts of "the beginning" in terms of time, The Big Bang Theory (conceived of by a Belgian Priest) deals with "the beginning" in that context.

There is a specific term used to define "the beginning" of elements in the sense of time, thus the beginning of machines in the sense of time, which is called Big Bang Nucleosynthesis.

Following nucleosynthesis, in time sequence, more complex machines developed, which we call stars.

Going on in time sequence in Big Bang cosmology, once those stars formed they then produced even more elements, i.e., more machines.

Clearly then, cosmological evolution advocates and hypothesizes that machines replicated, and/or formed other machines, in the earliest evolutionary processes of The Big Bang.

This is a good place, then, to characterize machines as being able to replicate other machines, but to characterize organics as being able to reproduce their own kind, but change through morphing.

Machines replicate not only their own kind, but other kinds of machines, but observation gives us evidence that life, in its organic reproductive process, reproduces only its own kind but experiences morph from time to time.

This is also a good place to mention that the combination of machine and organic is really what science fiction likes to call "a cyborg", a combination of inorganic machine with non-machine organics.

But, we can also see that organics cannot exist without the underlying machine foundation which organics extend upon.

We can also note that death, then, is the removal of the organic essences, so that the entity can revert back to the purely inorganic (machine) components underneath the organic level.
