No, what crashed the world's financial systems was the selling on of
domestic mortgage debt which had been generated from banks loaning out
money to people who did not and would never have the means to repay
the loan.


In other words, selling bits of paper they knew to be worthless.

If you or I did this, it would be called fraud, but somehow the big
financial institutions can dress it up in fancy language and get away
with it.

The governments has always sold worthless bits of paper ever since paper
currency became the norm, and the government has always been able to act
like a legalised Mafia, which is, after all, what a governemnet actually
is. The top Mafia that self legalises itself, as the price you pay for

Yes, of course -- why do you think banks and other financial institutions
are so keen to sell on debt? It is called hedging the risk, or
as some might say, distributing or even sharing (as in passing on)
the future losses to others.

If you or I did this, it would be called fraud, but somehow the big
financial institutions can dress it up in fancy language and get away
with it.


See, for example,

http://www.amazon.co.UK/Hedging-Instruments-Risk-Management-Derivatives/dp/0071443126

But remember that the whole financial system is built on perception and
trust -- how much is that GBP 10 note in your pocket actually worth, or
that stock certificate for 100 shares in Northern Rock plc?

One day the piece of paper is very valuable because others are prepared
to exchange it for lots of other pieces of paper or digits in a computer
database, and sometimes the item has even less value than the paper on
which it is printed.

Talking of digits in a computer database, do many banks have the active
account balances stored in nothing more than magnetic or optical media
or the last printed statement?

Atmospheric extraction is totally unfeasible. Have you _any_ idea how
big the atmosphere is, and how small in comparison any man-made
extractor would be?

Yes, at surface density, it is equivalent to a uniform layer a little
less than 5 miles thick over the surface of the globe, some 200million
square miles, making the atmosphere approximately 1billion cubic miles
at surface density.

How many would we need do you think?

That depends on how fast you think we need to do it. The argument,
whether you believe it or not, is that we have managed to cause the
problem simply by a few hundred large CO2 producers over a couple of
hundred years. So a similar number of capture units should be capable
of sweeping it all up in a similar time, probably faster.

At a few hundred feet per minute a single atmospheric extraction unit
with a scrubber area of only 1 square mile, would take around 20,000 to
remove all CO2 from the atmosphere, so a distributed system of 50 such
systems around the planet would clear the problem in less time that it
took to create it in the first place - and we don't WANT to get rid of
all of the CO2 or we'd be in for a very cold future.

And wouldn't it be better to use trees as we always have?

No, because trees rely on natural air movement to access the atmosphere,
not forced air movement. And they tend to decay or be burned, releasing
their captured CO2 in the timescale.

Because relativity says its so. ANY release of energy is accompanied

Its vanishingly small for typical mechanical and chemical energy, but
its there just the same.

If it isn't, relativity is falsified, and there is a huge hue and cry

Then you have completely misuderstood relativity. Energy and mass are
interconvertible but only under specific circumstances you will not find on
earth outside nuclear reactions. If release of energy is accompanied by a
reduction in mass then what you've got is nuclear fission. If you haven't
got nuclear fission then you don't get reduction of mass.

Outside of nuclear reactions, all you have is energy conservation and mass
conservation, and they are entirely separate. One form of energy can be
converted into another, but not into mass, and mass can never be converted
into energy.

Storing electrical energy in a battery is actually a conversion of
electrical energy into chemical energy. Discharging the battery is the
reverse. Mass is not involved in any way, even infinitessimally. If you
think it is, you are just wrong, wrong, wrong.

used to be some of the really big generators needed to be left
spinning while cooling off......

They use the spare overnight power to pump the water back up in a
stored
hydro power station so that it's full in the morning when everyone
turns
their kettles on, so it isn't wasted.

except you only get back maybe 75% of what you put into the pumping
during generation.

And then you lose some more pushing all the power to N Wales and
getting it back again to somewhere useful.


but it was very close to a couple of nuclear power stations (probably now
closed) so the distribution losses would actually be rather low.

it is still running, but nt for much longer
http://www.magnoxnorthsites.com/abou...ts-and-figures

even then the pumped scheme is a bit bigger scale than the local
nuclear station - Dinorwic can generate at over 2 GW.

http://www.fhc.co.uk/dinorwig.htm

all this green electricity that seems a lot more reliable than all
those dinky toy wind turbines....


There is nothing green about dinorwic as far as co2 is concerned.
It is a net producer of co2, far more than the nuclear plant .

It is just a "rechargeable battery" nothing more.

true, but not the whole storey.

Dinorwic is there to improve the operation of the grid as a whole.

What it does is allow the grid to operate with a higher base load from
the more efficient plants and do something useful with the excess as
the load varies.

It is there to satisfy peaks in demand and uses more energy to recharge
overnight than it can ever deliver during the day. In doing so it may reduce
the co2 output from the total generating capacity, it may not depending on
the conditions at the time.


Yes - because the big stations take a lot of time to bring up and even
longer to shut down cleanly.

The biggest innovation in Dinorwic was not using it as a battery, but
how fast it can react to load changes.

Operating the grid with dinorwic in place is supposed to be equivalent
to having another 2 big nuclear stations in operation

To be more green we would just drop the supplies to some areas when the peak
demand got to high, however the customers may revolt.


the assumption here is that shedding load doesnt cause side effects,
and can be done quickly enough without causing stability issues to the
grid itself.

In reality there are lots of sites where unexpected shudowns cause
issues (data centres, hospitals ?).

also many sites where power continuity is critical have backup
generators - now those really are inefficient compared.

then we have all those widely varying input devices that cause
instability and so cannot be relied on within the base generation -
windmills for example.....

After all, it was primarily built as a source of weapons-grade plutonium,

Excellent points to keep in mind, and presumably the government thought
that it was in the best interests of the citizens of the UKofGB&NI to
produce plutonium rather than electric power.

It would seem that the French do thing differently though, as France
produces 77% of its electricity by nuclear power, and thus they are
not held hostage to coal, gas, and oil supplies in the same way as
UKofGB&NI electric power generators.


The important thing is the French have run their Nuclear power industry
on military lines, if something needs fixing it's done.

The EU now want it privatised, which is worrying as Three mile island
was run that way.

Remember the theme of the movie the China Syndrome was it costs
money to do things properly, so under a privatised regime it's tempting
to cut corners.

Whereas the Russian way is, what corners?

er the car scrappage scheme isn't a "green" measure it's an economic
one to help the car companies through the downturn without giving
them a direct cash hand out.


Wonder why we're helping other countries when we're in such a state
ourselves?

And wouldn't it be better to use trees as we always have?

No, because trees rely on natural air movement to access the
atmosphere, not forced air movement. And they tend to decay or be
burned, releasing their captured CO2 in the timescale.


How much energy do you think that will involve? How will these 'scrubbers'
work exactly, and how will they be powered?


Electricity... coming from power stations... powered by coal or gas.
It's bleedin' obvious innit?

The only way we are ever going to get out of it is by acting together
each to do what we can.

Only way we are ever going to get out of it is if we put the goal
of Nuclear fusion on the same resource and priority footing
as the Manhattan project


I hope not we have already spent more than the Manhattan project
and I don't want to see fusion research stopped.


Nonsense, Manhattan between 1942 and 1945 took over 130,000 people,
70,000,000 pounds of silver from the U.S. Treasury reserves was used for
coils, and god know how many other resources

Projects at over thirty US sites, cash cost was only around $2B, but in real
terms
probably around 10% of the US's war time production capability.

If we put 10% of the industrialised worlds resources into fusion,
it would either be proved or disproved very quickly

But it's accountants that run the 21st century

Unless it's fed by gravity, like the Chatsworth one that was

Isn't consuming CO2 meant to be a GOOD THING? ;-)
We need more consumption of CO2!

Carbon Capture is the way to go and it is the ONLY way that Britain will
make a significant difference.


The energy to capture all that CO2 will need a dozen nuclear power plants
to drive it.


Or with the Severn and Mersey tidal barriers only 8 nuclear power stations

Common sense. ;-)

At school, over 40 years ago, we used to debate the dubious value of
exams and whether being sent to the glue factory on failure should be
real or allegorical.

I still think we'll have to do it sooner or later, its only conflict and

Does it matter, as long as the CO2 it produces is less than the CO2
taken out of the atmosphere during the life of the facility?

BTW, this is only one atmospheric extraction concept.

Simply dropping the mean ocean temperature by 1/500th degC compensates
for the entire annual anthropgenic CO2 production (a fact that itself
questions the anthropogenic argument). There are may ways of
implementing that and the oceans have a huge area.
