Fission-fusion hybrid reactor

A new thorium reactor concept?

Speculation alert:  It is a bad habit of mine to comment upon things I don't know beans about.  Hence the speculation alert.

On with my comment...

This seems unnecessary since the Thorium will transmute into an isotope of fissionable uranium.  So why do you need the fusion reaction?  It introduces a level of complexity that isn't needed.

The problem with fusion is that it uses more energy than it produces.  It will produce neutrons, and it can be used to transmute the Thorium, but the Thorium can do that by itself.  What problem does this solve?

It is a gas-cooled reaction, which is different from the molten-salt designs that are being developed.  ( I haven't kept up with these developments lately, so I don't know when a prototype will be available.  The goal was to have one in this decade.)

If a gas-cooled reactor is somehow better than a molten-salt one, then maybe that is the advantage.  But the article doesn't go into that.  It did mention that it is sub-critical, but so what?  Criticality is not what causes it to become dangerous in a molten-salt design.  The problem is with solid-fueled reactors that use water for cooling.  Molten-salt reactors solve that problem.

Thorium based molten-salt reactors have already had proof-of-concept testing way back in the seventies.  These tests did not use Thorium per se, but since Thorium only needs a neutron source to get it started, this is absolutely feasible.  Politics stopped this concept, it wasn't technical.

This elaborate design might be feasible, but the design has only been tested in computer simulations.  If it is feasible and can escape the politicians, then it could maybe work.

off-grid post 1.29.20

It has rained a lot this winter.  Actually, this isn't much of a winter.  Very mild, but
rainy.  It has given me a lot of practice with my water capture techniques.  Water filtration
has been practiced on other occasions.  As a matter of fact, the best system would be to
capture the water and then use a powered filtration system to clean the rainwater.  The
water that you can capture is still going to have dirt and whatnot in it.  It may also
have bad stuff in it, so it needs to be cleaner yet before it can be said to be potable.

A Berkey filtration system can take some water like that and finish the job.  For an extra
measure of safety, you can add some chemical treatment to it.  No need to get sick from
the water.

Therefore, if there's rain, I can capture "enough".

Trouble is, out there it can be very, very dry.  I need to check and see what kind of winter
they have had out there.  In the first three years, I watched this stuff like a hawk,
but in the last two or three winters, I have not watched it much at all.

Back to the weather:  it has rained so much out here this winter, I haven't any place to
put this water.  I don't have the filtration system in place, so mostly, I just dump
the water.  It seems like a terrible waste.  You learn to appreciate something you have
to work hard to obtain.

off-grid post, 1.26.20



There's not much posting here lately.  Well, here's a post to keep this blog going.

The off-grid project is a go.  In fact, the lack of posting is not an indication of quitting
the project.

I try to do a little bit every day.  Maybe that is exaggerating a bit, though.  I try to
plan a little every day. 

There are two plans for projects that are in the works, but like everything else, it is on
hold for now.  The ladder project has been in the planning stage for over a month.  The
current plan is to place it on the west side of the trailer, near the rear bumper.

I think that location is the best.  It shouldn't take this long to come to that conclusion,
but that is only because I don't spend enough time planning.

The other plan is a tentative one as well.  I have decided to revisit the Quonset concept.

I'd like to use concrete for the roof, but that is very heavy and messy stuff.  There are
tradeoffs for everything, though.  If I were to use a tarp again, it cannot be exposed to
the elements.  That means a square outer perimeter, with a sturdier exterior that can
withstand the elements.  Metal siding is a possibility.  There are other options.

Since it will need a sturdy exterior and a frame, why not use the tarp?  It doesn't have
to be a cattle panel either, but that is pretty strong stuff.  The problem with cattle-panel
for a ceiling is that it may move around.  It needs to be secured so that it doesn't move.

A possibility is to use insulation between the inner ceiling and the outer roof.  Also,
the sides can be insulated as well.  There's plenty of space for insulation and dead space.

Why use a Quonset at all?  It is the quickest and easiest way to get a roof up.  However,
that is not the way it went the last time.  It was largely because of the tarp, though. 
The wind blew it all over the place, and it was just about impossible to get that thing
on top of the cattle panel.  Once I did get it on there, it wasn't very straight nor
pretty.

Secondly, a Quonset wouldn't be necessary if I used the trailer. 

That is a whole different thing right there.  Which brings me back to the Quonset.

A trailer needs to be towed out there.  It needs a cover, which entails a construction
project of its own.  Of course, I've been planning that one too.

A move out there is not contemplated unless it becomes necessary.  At the time, I am in
good shape here.

I continue to practice living like I'm off-grid without actually being off-grid.  I can
expand upon that if I were to buy some solar panels and batteries.  For the time being, I
am minimizing energy expenditures.  From that info, I can calculate the minimum power
to run the trailer once it is on the property.  Batteries and solar panels are expensive.

Scientific American: Store Renewable Energy as Liquified Air


Scientific American: Store Renewable Energy as Liquified Air


Update:

Been there done that.  Uses too much energy, I suspect.


Comment:

This is an intriguing idea.  Instead of using a battery, atmospheric air is cooled to a liquid state.  When it warms, it expands enough to drive a turbine that can produce electricity.  It is claimed to be about 60 percent efficient.

Now if you were to use nuclear energy to liquefy the gas, you could have a plausible means of powering an auto or a vehicle.

Feasibility for this type of application depends upon how big of a tank is required to produce the needed power.

Wefunder Campaign Extended to Mar. 1, X-rays Show: FF-2B's Best Shot is All Hot, Images Catch FF-2B in Action, New Video Series on Crisis in Cosmology

Summary:
  • Wefunder Campaign Extended to March 1

Wefunder Campaign Extended to March 1

We've just completed our third successful financial audit. Because of this we can now extend our Wefunder campaign through March 1st. Without this audit, SEC regulations limited us to ending the campaign 120 days after our fiscal year ended, which is Jan 31st. We are happy that we can stretch this campaign a little bit longer. So far, we've raised $395,000 from 165 investors. We need to raise only $5,000 more to reach our minimum goal of $400,000, but we hope to go way beyond this in our final month. Thanks to everyone who has invested or is considering doing so.


X-rays Show: FF-2B's Best Shot is All Hot!

The latest data from LPPFusion's lab shows that all the plasma in our tiny fusion plasmoid is hot, not just some of it. Hot in this case means 600 million degrees K, sixty times hotter than the center of the sun. This new result shows that our results are being fairly compared with those of other fusion approaches and that we really do have the hottest confined plasma in the fusion race.

LPPFusion published in 2017 results that showed our device FF-1 had achieved the hottest confined ion energy of any fusion device—energy equivalent to a temperature of 2.8 billion K. However, some critics questioned if all the ions were this hot, or if there was a hidden background of cold plasma. In this alternative, a small number of hot ions in our plasmoid were colliding with a large number of cold ions to produce the fusion reactions we observed. So, critics argued, our record did not really reflect what was going on inside the plasmoid that produced the fusion reactions. (These critiques were never published, but were conveyed to us in conversations.)

The new X-ray data that we analyzed this week rules out this cold-plasma idea. X-rays are emitted when hot electrons collide with any ions—hot or cold. So, the quantity of X-rays emitted measures the total number of ions (charged atoms) present in the plasmoid. At the exact same time, we are measuring the number of neutrons produced by fusion reactions, which are a measure of the number of hot ions. By measuring the ratio of neutrons to X-rays (and correcting for temperature and other factors) we can measure the ratio of the number of hot ions to the number of total ions.
When we did this for our best shot so far this year, shot 1 of October 21, we found that while the neutrons showed 0.125 J (watt-sec) of fusion energy was released, only 0.035 J of X-rays energy was emitted. (See the graph—the big peak on the right is from the neutrons and the small peaks on the left are from the X-rays. The third peak from the left was produced when the fusion reactions took place. The horizontal axis is time in microseconds. Neutrons travel much slower than X-rays, so arrive at our instrument later.) Based on this ratio, we calculated that the number of hot ions is the same as the number of total ions, with a 15% error margin. So, at least for this shot, there's no room for cold plasma—it is all hot. We'll soon be doing the same analysis for all shots we take.

Images Catch FF-2B in Action


These new images from inside our Focus-Fusion-2B experimental device show the development of the filaments of current (bright thin parallel lines) in the early stages of each pulse. The filaments are a crucial step in compressing and heating the plasma to get fusion reactions. The images, taken with our ICCD camera using an exposure time of only 5 ns (billionths of a second) show the current sheath moving down the anode (towards upper right) as viewed between the cathode vanes (diagonal black bands). The top-to-bottom size of the images is 2.5 cm.

They show the development of the sheath from 230-570 ns after the current starts flowing. So, the events are happening about 6 million times faster than you see them in this GIF. The key positive features of the images are that the filaments (running from lower left towards upper right) are evenly spaced and thin—only 200 microns in radius. Those characteristics should lead to a dense plasmoid and rapid fusion burn. But the images also show the challenge that we currently face—the front (right) edge of the sheath is not a single, sharp line, but two separated fronts. This is caused, we know, by the oscillation in current that produces an early small pulse of current, followed by a bigger one. In the region between the fronts the filaments are twisted and disorganized. This leads to poor compression and less fusion. However, we are working hard to eliminate the oscillations so there is a single front and the filaments will be neatly organized all the way to the front of the sheath. In the past three months, we have achieved significant progress in greatly reducing the oscillations, but have not yet reached the threshold for a new increase in yield.

These images are produced from 10 separate, but very similar, shots. The flickers in brightness are caused by changes in camera filters and sensitivity—the real brightness is steadily increasing during the time covered as the current flowing through the sheath increases.

Wefunder Campaign Enters Home Stretch

As we have reported to all investors and supporters, LPPFusion is again crowdfunding on the Wefunder website. Through the Wefunder site, anyone can now buy LPPFusion shares. We started this second campaign on Nov. 15, 2019 and now we are in the last two weeks, with the campaign ending Jan. 31, 2020. So far, we've raised $336,000 from 133 investors. We need to raise $64,000 more to reach our minimum goal of $400,000. We're confident we can do that with the help of new and old investors.

This is your chance to help decide if and when fusion energy becomes reality. Humanity needs fusion to move forward. So far, LPPFusion has made the most progress towards achieving net energy for the least resources. With only $7 million invested, we have published peer-reviewed results thousands of times better than any other private fusion company. Our ratio of energy out to energy in is only 1/3 less than that achieved by JET, the most successful government fusion program—and they got that record back in 1997.

Your investment, a minimum of $1,000 for 8 shares, will make more of a difference with LPPFusion than with any other fusion project. Our company valuation right now is only $38 million, so you will get the best bargain in fusion. For non-accredited investors, the Wefunder campaign is at present the only way to invest in LPPFusion.

We realize that not everyone who wants to support our fusion effort can afford a $1,000 investment. For those who want to contribute, we will be initiating a major donation drive, with no minimum contribution, in February. We'll be announcing the details shortly. Our goal remains to raise $1 million from all sources as soon as possible.

Light Elements Weigh in on Crisis in Cosmology

A bedrock prediction of the Big Bang theory has been contradicted by abundant observations, according to a new study by LPPFusion's Chief Scientist Eric Lerner which he presented Jan. 8 at the American Astronomical Society Meeting in Honolulu, deepening the already widely-discussed crisis in cosmology. The study looks at the origin and abundance of three key light elements that are hypothesized to have been created by the Big Bang. Precise amounts of helium, deuterium and lithium are predicted to have been formed by fusion reactions in the dense, extremely hot initial instants of the Big Bang.

For both lithium and helium, the study shows, observations of abundances in old stars now differ from predictions by more than a dozen standard deviations and the gap has been widening at an accelerating pace. The oldest stars have less than half the helium and less than one tenth the lithium than that predicted by Big Bang Nucleosynthesis theory. The lowest lithium levels observed are less than 1% that predicted by the theory. Indeed, the evidence is consistent with no helium or lithium having been formed before the first stars in our galaxy.
Li vs Fe abundance for the 26 known dwarf stars with Fe/H<10 ppb. These are the oldest stars, with the least contamination from earlier stars. Dark blue dots are measured values, red dots are Li upper limits and light blue dots are Li and Fe upper limits. The BBN predicted range of values is shown by the red solid lines.

Equally important, the study shows that the right amounts of these light elements have been predicted by an alternative explanation, which hypothesizes that these elements were produced by stars in the earliest stages of the evolution of galaxies. This alternative explanation, which Lerner calls the Galactic Origin of Light Elements or GOLE hypothesis, derives from theoretical expectations that the first generation of stars to form in a galaxy are intermediate-mass stars that are from 4 to 12 times as massive as the sun. These stars burn hydrogen to helium in tens to a couple of hundred million years, much faster than our sun's burn rate of ten billion years. The helium then disperses in powerful stellar winds during the late stages of these stars' lifetimes. Cosmic rays from these early stars, colliding at high energy with other nuclei, produce deuterium and lithium.

Lerner's new work was covered in a number of news reports including the online magazine
Inverse, Futurism, Courthouse News Service, and Space Daily.

The science website "See the Pattern" posted Dec. 21 a new hour-long illustrated interview with Lerner discussing the relationship between the companies' fusion research efforts and his research in cosmology. The physical theories that guide the development of the plasma focus device for fusion experiments arose from studies by Lerner and others of quasars, the giant explosions deep in space. The tiny plasmoids in the device, where the fusion reactions take place, are in essence ultra-scaled-down versions of quasars. So, instead of a "star in a bottle" our fusion device is more a "quasar in a bottle".

Lerner's research in fusion and in cosmology have been closely linked for decades. In addition to the quasar work, Lerner performed calculations about the
origin of the large-scale structure of the universe, based on the properties of plasma filamentation—an instability that generates tornadoes of electric current and magnetic fields on all scales. On the cosmology side, these calculations, together with observations of giant superclusters of galaxies, showed that the largest structures must have taken hundreds of billions of years to form, far longer than the time available since the hypothetical Big Bang, so this was strong evidence against the Big Bang theory. On the fusion side, quantitative understanding of these filaments, which form on a tiny scale in the plasma focus device, allowed solid predictions of how the device would work best.

Many of the conflicts between Big Bang theory and observations that are emphasized in the new study have been known for some time, especially the "lithium problem". But most cosmologists have dismissed them as "anomalies" in an otherwise sound Big Bang "concordance cosmology" theory. On the contrary, Lerner contends that the light elements results join the better-known Hubble-constant and closed-universe problems in a long list of contradictions between Big Bang theory and observations. "The Big Bang should have resulted in the annihilation of matter and antimatter, leaving a surviving density of matter that would be a hundred billion times less than that observed," Lerner points out. "To avoid that outcome, Big Bang theory requires an asymmetry of matter and antimatter with consequences, such as the decay of the proton, which have been contradicted by extensive experiments. In addition, an expanding universe should lead to declines in the surface brightness of distant galaxies—but those have not been observed either, as I and my colleagues have shown in
published papers. The list of contradictions goes on and on. For cosmology to advance, the basic hypothesis of the Big Bang has to be abandoned. The real crisis in cosmology is that the Big Bang never happened."

Quonset idea being reconsidered

Updated,

1.9.20:


The latest iteration of this concept is to use the cattle panels as usual but put in a metal sheet to attach to the panel.  Then pour some concrete to cover the metal.   It would be a thin layer of concrete alright, because of the extreme weight that a thick layer would entail.

No tarp this time.

A composting toilet would be used as opposed to a septic tank.  That would save money.

I'm thinking that a roof above the Quonset would help with the sun.



5.27.19:

This idea will be shelved as well.  It may be useful for utility buildings, but not as a dwelling.  The ergonomics would not favor it.  Not to mention that it would take a long time to construct something of any size at all.

Although it is shelved, it is not completely abandoned.  Not yet, at least.

The most efficient solution is to take the trailer out there.  It will need a septic tank installed.  I would also need electricity generation capability.  But all that planning can wait awhile longer.


5.26.19:

Just realized an error in yesterday's write-up.  Besides, upon further review, the digging option has been ruled out.  Why?  Too big of a risk of something unexpected.  For example, there could be solid rock in an inconvenient place.  I don't know how far the sand goes down.  It may go down hundreds of feet, or just a few.  Without any information about what is below the surface, it is too big of a risk to undertake.

Instead of doing that, I can scrape off the top layer of sand, and push it against the quonset.  This will shield the quonset from the elements.  That much is possible.

The quonset structure will be above ground.  That is, if it ever gets built.

One thing that I have determined so far is that it is possible to build a small one.  It may take a couple weeks, but it could be done.  The sand can be piled on later.



5.25.19:

Here is an amended plan, which would include a new idea:

Concrete covered cattle panel constructed as an arch for the quonset concept.

Moving the dirt, and constructing the structure.

Use bobcat in order to move enough dirt for a 3 ft deep trench.  It would be 8 feet wide at
the bottom.  At a 45 degree angle, the entire width should be about 16.5 feet.  That is because
You'd need about 1.414*3 feet for the hypotenuse of an isoceles right triangle.  It is isoceles
because it is as wide as deep, so the lengths of two sides are equal.  Therefore, the math
yields about 16.5 feet in width, which would angle down at a 45 degree angle to the 3 foot
level, where I would stop digging.

In order to make it wider at quonset floor level, make it wider at the bottom.  Add another
2 feet to each side making it 20.5 feet wide.  Length wise?  Depends upon how many concrete
"bunkers" I would want to make.  If only one, it would be 16.5 feet in the original
config above, plus any length desired.  Eight more feet would yield 24.5 feet in order to
allow a steep grade down below.

This layout may have to rendered to paper, by the way...

Getting into details...

A much narrower trench would be dug here on each side.  This is to set the cattle panel into
place using concrete.  Place each end of the cattle panel into the trench on each side. The
panel will be bent into semicircular shape that would be about 6 feet tall.

Fill in the narrow trench with concrete.  This will set into cattle panel into position.

Place forms on each side of the cattle panel.  These forms will be about 4 inches deep, and
about 6 inches wide.  Pour concrete into the forms, and continue doing so until ground level.
That would require 48 pours of 4 inches apiece in order to cover the 16 feet of cattle panel.

Refill the empty trench with dirt, but not all the way up at one time.  Put the forms in to
prevent dirt from getting to the boundaries of the cattle panel.  The dirt is used in order
to support the wet concrete until it can set.

Finish out the concrete pours until all of the cattle panel is covered in concrete up to 6
inches thick.  Remove the dirt and leave an empty space inside that should be six feet tall.
That height would be sufficient to walk under it.

It will be necessary to remove the last 6 inches or so of dirt at the bottom in order to
have more headroom.  After all the pours, the arch will be hardened, and therefore, does
not need the support of that dirt.

Concrete bags could be placed at each end so that it would be enclosed.  The dirt would then
be pushed up against the bags forming a berm at each end.  If concrete bags aren't desired,
then metal or perhaps wood could be used for the three feet or so of the berm.

Each section would require 48 pours of concrete.  After some thought, it may not be necessary
to fill in the dirt as the concrete is poured.  Instead, just 4" sections could be poured at
a time.  Two by fours eight feet long could be used for forms.

Each pour would take 1.65 60 pound bags.  That means for each 8 foot section would require
nearly 80 bags of concrete!  Yikes!  The calculate allows for 6" width, and 4" deep.
It is 8 feet long, yielding 8*.5*.33 cubic feet, or 1.32 cu ft.  An 80 pound bag is
.6 cubic feet.  A 60 pound bag is .75 times that or, 1.65. There are 48 pours of 4 inch
each, which yields 16 feet.

But it would not be impossible, as I could haul the concrete a bit at a time.  In order
to haul 80 bags of 60 pound concrete, I could divide it up into 5 loads.  Each load
would be about a thousand pounds.  My van can handle that.  Could I handle this much
physical labor?  Only at a slow pace.


5.24.19:

It seemed that in the recent past, this matter was settled.  Now it isn't.  Just goes to show you that final isn't final.  At least not in this neck of the woods.

A quonset holds many advantages.  Unfortunately, there are disadvantages.

As written earlier, going underground is an attractive option for this project.  The advantage of a quonset is that it won''t require much construction in terms of a roof.

But the quonset hut built before didn't hold up.  However, if it were to be built underground, then the wind cannot blow the tarp to smithereens.

Another idea is to use concrete bags without mixing the concrete.  Just leave the concrete in the bag, and let the rain seep in and harden it.  Stack the bags up about 3 feet high, while starting in the ground 3 more feet, and you have six feet of head room.

Pile that dirt from the hole back on top of the concrete.  Then all you have is a big mound, but underneath you have a livable area that is out of the elements.

Of course, you still need to cover the roof.  The cattle panels will just outline the inner ceiling.  Perhaps some insulation can go between roof and ceiling.

A bit more thought yields the thought that animals may find their way into the structure.  It would have to be fenced in, and screened.  Access could come from a ground-floor type arrangement.

The ground floor will be a fenced in area, with a ladder that would allow access to the lower floor.

Post holes would be dug in at the lower floor, and rise 8 feet about ground level.  The roof would be placed on top of this.   The dirt berm would rise 3 feet, and backed by the concrete bags.  At the top of this, cattle panels would go all around.

This plan is incomplete.  More thought is necessary, as the idea is new.

Mining the sky is a real possibility

This danger could be converted into an asset:


Asteroid that could cause 'violent' sky explosions approaching Earth


Imagine what could be mined from this asteroid.  It takes many, many launches in order to put something this big into space.  It would seem economical to capture these things and use them instead of worrying about them.
