Incinerating nuclear waste in the Sun (to my knowledge)
does not occur today. Discussing it is within the bounds
of science fiction. ABIA and ABLN are newsgroups that
discuss science fiction. You are overly argumentative.

You have chosen _not_ to comment about my statement
that an affordable ion propulsion system would make
feasible incinerating nuclear waste in the Sun.

Anywhere an energy differential exists (the illuminated
side of a capsule versus the dark side of a capsule) there
is the potential of an energy source. As you approach
the Sun, photon density increases (inverse square law)
and increasing energy amounts are available. And
gravity also operates by inverse square law -- gravity
will prevent photon pressure from 'blowing a capsule away'.

The Sun's energy could be harnessed to drive an ionic
retrorocket, permitting a capsule carrying nuclear waste
to spiral inward to incinerate in the Sun.

This is very high level, but it contains no fuel expenditure
limits. And if we're going to incinerate a capsule, the schedule
is not critical.

To my knowledge terrestrial nuclear waste is _not_ being
incinerated in the Sun -- that makes the discussion
science fiction. ABIA and ABLN are science fiction newsgroups,
and the discussion is on topic.

Don't tell me where to post.

Like all rocket engines, ion propulsion engines operate by
conservation of momentum. Throw something forward, you get
pushed backward.

Ion propulsion systems (which to my knowledge have not been
implemented) operate by imparting an electric charge to
particles (mass) and then electrically repelling those
charged particles. In a ion retrorocket, the escaping
particles' forward momentum would impart a backwards force
to the capsule, reducing its velocity. Continuous braking
force applied to a capsule orbiting the Sun will cause the
capsule to spiral inward, and eventually to incinerate.

Ion propulsion systems are categorized as weak -- low force.
Obviously we want to save ion mass, so to make this concept
practical, we would have to engineer an improved ion retrorocket
configuration that used relatively few _extremely_ high velocity
particles. That solves the fuel expenditure problem (and it
sounds like a weak particle beam weapon -- no problem in
open space).

As I pointed out in my earlier message, the photon density
difference between the front (illuminated) capsule side and
back (dark) capsule side provides an energy differential
that can energize an electric power source for the ion retrorocket.
We are _not_ dependent upon a drum beating rabbit for electrical
power -- the Sun's light powers the ion retrorocket. And gravity
(also inverse square law) more than compensates for outward photon
push as the capsule slowly spirals ever closer to the Sun.

This is an engineering problem, not a feasibility problem.

Earlier you were giving me a ration because you claimed
what I proposed was impossible -- it is possible. Now
you are giving me a ration about the cost of Earth launch.
Propose a less expense alternative that completely removes
nuclear waste. Are you volunteering to store nuclear waste
in your neighbors' and your basements? On the Moon? Mars?
A big asteroid?

I find Larry Niven and Jerry Pournelle's novel "Lucifer's Hammer"
interesting. I am sure you know that "Lucifer's Hammer" discusses
the societal effect after Earth is hit by a substantial meteor
shower. What is the effect? Infrastructure is disrupted, wide
area commerce is disrupted, energy supplies are disrupted
and people make due with local resources. In short, people
are poor and they cope.

As energy prices continue rising, I believe that electricity
generation by nuclear energy will become increasingly
attractive. That will increase the quantity of nuclear waste
produced and the _annual cost_ of dealing with that waste --
recurring overhead expense. Increased cost means less
discretionary resources -- we get poorer because of rising
energy costs.

Bituminous coal (the anthracite coal is gone) also can be
used to produce electricity. Bituminous coal technology
and its costs are well understood.

I have addressed this on the science fiction level. If
they are interested, the experts can address this on the
engineering level. I have shown feasibility and I have
no mission to show affordability.

Either way, the problem will not just go away. Apparently
after twenty years' study we have _not_ selected an 'optimal'
storage strategy (loosepack versus densepack) for nuclear waste,
and coal electric generating plants are (being?) mothballed.

Given the nuclear waste storage solution has been studied
for twenty years, and an 'optimal' (loosepack versus densepack)
solution has not been selected, I believe the 'clean up our own
messes' analogy is appropriate. And a sufficient quantity of
nuclear waste gives nasty burns. (Ref: Any biography of
Marie Curie.)

Prior to the invention of the gasoline powered internal combustion
engine (an engineering problem) there was no safe way to utilize
volitile gasoline's energy. Example: Olympic runner Glenn
Cunningham was burned severely in his youth when he mistook
gasoline for kerosene and attempted to light a wood stove
in a schoolhouse. Remember kerosene lantern techology --
they didn't use gasoline.

My understanding is that plutonium harvested from nuclear
waste is both _extremely_ toxic and also is dangerous
from a _terrorism_ point of view. I understand the general
concensus is _not_ to reprocess nuclear wastes to recycle
fissionable materials. Of course, we are not (yet)
freezing in the dark.

Nevertheless, were fissionable materials to be recycled
from nuclear waste, the remaining debris still presents a
storage/disposal problem -- recycling is _not_ 100 percent
efficient and some radioactivity remains in the waste.
I do _not_ know if additional hazardous wastes (e.g.,
contamination of solvents) are created during the nuclear
waste recycling process.

I am an old amateur radio operator, and I know that Sun storms
(which disrupt the Earth's ionosphere and terrestrial RF
communications, not to mention inducing voltages across
terrestrial long lines) are predictable _months in advance_.
In an earlier message I already commented that most people
are smart enough to avoid cloudbursts.

Then we need ion retrorockets with greater 'fuel' efficiency.
(I am proposing ion retrorockets energized by incident energy
from the Sun, but I acknowledge the need for some mass
consumption in creating ions.) This is an engineering problem --
delta (m*v) = F delta t.

Earlier you were complaining about the sheer volume of
nuclear waste and the cost of launching it. Now you
propose launching it into orbit for later retrieval.

Prior to the invention of the gasoline powered internal combustion
engine (an engineering problem) there was no safe way to utilize
volitile gasoline's energy. Example: Olympic runner Glenn
Cunningham was burned severely in his youth when he mistook
gasoline for kerosene and attempted to light a wood stove

"Precious bodily fluids"? Did you just view the film
"Dr. Strangelove"? (Do you like word games?) Who was
your favorite actor: Peter Sellers or Slim Pickens?

IMO deliberately creating orbiting spacejunk is _not_
responsible policy. If you did not dispose of your
household garbage properly, your competency would
be questioned.

As to your concern about contaminating the Sun, the Sun
is a thermonuclear fusion furnace. There is no danger
of contaminating the Sun. [Of course, if you launch
a hu/manned mission to the Sun's surface to touch down
at night you might encounter problems. (ROTFLMAO!)]

IMO desert energy farms are a better concept. Unused desert
acreage is inexpensive and plentiful. The energy farm can
employ eutectic salt thermal storage to store excess energy,
can help support daytime terrestrial electric peak needs directly,
and can draw stored heat from eutectic storage at night. The
system might be photovoltaic, a heliotrope (reflected sunlight
converted to heat), or both. And it is (less expensive and)
easier to build and maintain systems that are located on the
terrestrial surface.

Feasibility is a scientific concern. Affordability is an
engineering concern. This is one significant difference
between science and engineering. For example, science
seldom addresses _maintainability_.

  >>after twenty years' study we have _not_ selected an 'optimal'

BTW, while some electric generating plants were mothballed
(local examples), many coal burning electric generating plants
were converted to fuel oil or natural gas fuel usage, _not_
mothballed. Presumably these fuel oil and natural gas fueled
electric generating plants could be returned to bituminous coal
fueled usage if necessary.

 >Yucca mountain.

IMO the ever increasing volume of nuclear waste might
FORCE a densepack solution. We'll keep dropping the
waste down the hole while scientists keep studying and
drawing salaries. Eventually the hole will fill completely.
That implements densepack without a scientific decision.

I am not qualified to provide nuclear engineering opinions,
but I understand generic engineering, generic economics
and human nature.

You have _not_ demonstrated that _some_ implementation of
an ion retrorocket energized by the photon density difference
between a capsule's front (illuminated) side and back (dark)
side providing continuous weak braking force and causing a
capsule orbiting the Sun to slowly spiral into the Sun is
not feasible. If the goal is incinerating the capsule, the
spiral duration is not relevant.

Photon pressure increases by inverse square law, but gravity
also increases by inverse square law and gravity is stronger
than photon pressure.

I believe it is feasible. Affordability (and maintainability
throughout that long spiral) is an engineering problem.

You have _not_ demonstrated that _some_ implementation of
an ion retrorocket energized by the photon density difference
between a capsule's front (illuminated) side and back (dark)
side providing continuous weak braking force and causing a
capsule orbiting the Sun to slowly spiral into the Sun is
not feasible. If the goal is incinerating the capsule, the
spiral duration is not relevant.

Photon pressure increases by inverse square law, but gravity
also increases by inverse square law and gravity is stronger
than photon pressure.

I believe it is feasible. Affordability (and maintainability
throughout that long spiral) is an engineering problem.

Earlier you were complaining about the sheer volume of
nuclear waste and the cost of launching it. Later you
proposed launching it into orbit for later possible retrieval,
drawing the analogy to valued gasoline (which was burned as
a waste product prior to the invention of the internal combustion
engine). Your scepticism evolves nicely.

Prior to the invention of the gasoline powered internal combustion
engine (an engineering problem) there was no safe way to utilize
volitile gasoline's energy. Example: Olympic runner Glenn
Cunningham was burned severely in his youth when he mistook
gasoline for kerosene and attempted to light a wood stove
in a schoolhouse. Remember kerosene lantern techology --
they didn't use gasoline.

My understanding is that plutonium harvested from nuclear
waste is both _extremely_ toxic and also is dangerous
from a _terrorism_ point of view. I understand the general
concensus is _not_ to reprocess nuclear wastes to recycle
fissionable materials. Of course, we are not (yet)
freezing in the dark.

Nevertheless, were fissionable materials to be recycled
from nuclear waste, the remaining debris still presents a
storage/disposal problem -- recycling is _not_ 100 percent
efficient and some radioactivity remains in the waste.
I do _not_ know if additional hazardous wastes (e.g.,
contamination of solvents) are created during the nuclear
waste recycling process.

IMO deliberately creating orbiting spacejunk is _not_
responsible policy. If you did not dispose of your
household garbage properly, your competency would
be questioned. I have similar opinions about placing
nuclear waste in 'parking orbits' where someone
accidentally (or purposefully) can blunder into it later.
Imagine Larry Niven and Jerry Pournelle's "Lucifer's
Hammer" implemented with a multitude of nuclear
waste capsules.

IMO the ever increasing volume of nuclear waste might
FORCE a densepack solution. We'll keep dropping the
waste down the hole while scientists keep studying and
drawing salaries. Eventually the hole will fill completely.
That implements densepack without a scientific decision.

It also is the best motivator that I can imagine to develop
robotics. I wouldn't send humans down into that steamfilled
(heat of subcritical nuclear reaction vaporizing seeping
ground water -- pray that nothing leaks) densepack hole.

I am not qualified to provide nuclear engineering opinions,
but I understand generic engineering, generic economics
and human nature.

lvpokerplayer snipped much of my earlier response
without annotation. The issue is science (feasibility)
versus engineering (affordability, including maintainability).

No, you said the idea was not feasible due to fuel expenditure
required to counter excessive delta v. I pointed out the
feasibility of an ion retrorocket energized by incident photons
from the Sun. THEN you began discussing economics. Science
discusses feasibility. Engineering discusses economics (including
maintainability).

I saw "lousy idea ... gasoline", understood your point, and
commented that even with a desire for potential future
extraction of fissionable materials, nuclear waste is nasty
stuff to park where somebody might accidentally or purposefully
blunder into it. Again, imagine "Lucifer's Hammer" deliberately
implemented with a multitude of nuclear waste capsules. If you
park it for retrieval presumably it can be aimed and dropped into
the Earth's gravity well -- big hot rocks.

Slim Pickens played the character who worried about his
'precious bodily fluids' -- your quote.

'The Mouse That Roared' was a farce and a bluff. It also
reflected an era when the United States was relatively rich
and provided a large amount of domestic development
assistance in its foreign aid programs. I have what some
consider an odd viewpoint. My viewpoint is that we have
been exporting vast quantities of United States dollars
since the late 1960's in exchange for foreign petroleum.
We burnt the petroleum, the petroleum is gone, and now
those dollars are returning to haunt us, purchasing
United States factories, real estate and farmland.

As to cinema, I prefer Woody Allen in 'Bananas'.
'Bananas' is a futuristic comedic rendition of "1984".
The Energy Police are alarmed when Woody Allen's hosts
use excessive energy as they revive his timefrozen
body. The Energy Police chase Woody Allen because
the Energy Police do not like Woody Allen's antique
liberalism or his sexuality.

I wonder how often those underground explosions create (OOPS)

the problem by dispersing atomized nuclear waste.

This is science fiction. And who can say what direction
future engineering developments (and our rapid accumulation
of toxic nuclear waste) will lead us?

You have not convinced me concerning 'more efficient
utilization'. IMO California (and the nearby desert
areas) present the greatest opportunity.

I still believe that terrestrial energy farms (heliotrope or
photovoltaic) located on desert _acreage_ (LOTS with less
expensive collectors) with eutectic salt thermal storage of
excess energy are less expensive, more maintainable, and
modularly expandable/replacable. As to affordability,
I do _not_ observe our current energy sources getting
_less_ expensive. Terrestrial technology is understood today,
and who can what will be _competitively_ affordable in five years?

 >Question: why did you bring up anthracite coal, and why
 >do you believe it is gone?

Anthracite coal, a fuel with high calorific value and less
ash, got used up first. Then low sulfur bituminous coal
(with less calorific value and greater ash) got used up.
In the late 1960's when environmentalism became a vocal social
issue, we were begining to use higher sulfur bituminous coal.
Burning high sulfur coal creates sulfur dioxide gas, a gas
often characterized as having a 'rotten egg' smell. Sulfur
dioxide gas combines with water in your lungs to create
aching sulfuric acid.

You ever heard of a London pea soup fog? Ash from coal fires
combined with misty fog was nearly opaque and difficult to
breathe. We had a similar condition in my locale in the early
1900's. An engineer was elected mayor and enacted some
environmentally relevant laws.

"Used up" is an _economic_ sense. All the anthracite coal
is not gone, but the remainder is _not_ economical to extract
at current market prices. Ditto with low sulfur bituminous
coal. Higher market prices dictate a reexamination, but the
easy-to-extract coal is gone. Similarly, some oil wells that
were 'pumped dry' will be reopened and water / steam / solvent
extraction used to extract additional petroleum when market
prices rise sufficiently.

Apparently there are vast deposits of 'oil shale' in the
United States northwest central region -- petroleum bound
in porous shale. Very messy and uneconomical to extract
for fuel purposes -- mountains of powdered shale result.
But if you're freezing in the dark ...

Energy is all about affordability, and various forms of
environmental damage are included in the cost equations.
Energy conservation brings unpopular lifestyle changes but
reduces the various forms of energy costs.

Utilizing the Sun's energy was studied widely in the
mid-1970's (and before), but was not affordable given
the era's energy costs. Energy costs are _much_ higher
in the 21st Century, and I wonder when people will begin
dusting off those old studies.

That also would work in my local city park, but I do not
recommend that you try it. You would be hunted down and
beaten to death by young mothers with infants.
