FROM DAS: I read your post further down about the estimated USD 6 energy
cost. I need to ponder that. (I was thinking about the total cost of
smelting the ores etc, but maybe you have given a simple, effective
indicator.)

I have retained a copy of the Cobasys battery article as it's a good
explanation of how they work, but it does not, understandably, discuss the
cost of making and disposal/recycling.

My underlying point is, I suppose, about displaced enery consumption.
Electric trains are often considered wonderfully environmentally friendly,
whilst it is overlooked that you need, in most cases, regular power stations
using oil or gas, to produce the electricity in prodigious quantities. Only
a few regions, such as Switzerland, are blessed with truly environmentally
friendly power sources such as water (hydroelectric).
Same with electric cars. You need to make the batteries and, even if they
are, after all, quite cheap in energy and environmental terms, you still
need to build vast numbers of electricity generating stations to run them...

FROM DAS: Precisely. We can forget about the 'ifs' of fully laden trains
all the time. I have been on trains with standing room only, but these only
run on main routes and it doesn't occur throughout the day or throughout the
year. Even in the US I was on a well-patronised train, namely from Philly
to DC, and then from DC to NYC, but I am sure that's an exception, too.
(I.e. it's a main route.)

In principle you are right about shifts to trains if cars become less
available, but in a free society this is a pipe dream. In the ex-COMECON
countries there is still a quite high utilisation of trains, stemming from
the days of when it was very difficult for individuals to own cars (for a
variety of reasons) and when ticket prices were kept artifically low. But,
I suggest, this is falling as more and more people buy cars. The fact is
that the automobile is one of the most important (if not THE most important
factor) in the free movement of individuals (hats off to Henry Ford here).
You can see that despite the high fuel taxes in Europe and other places
sales of cars continue to rise in most years.
It has been calculated in the UK that even if only 10 percent of freight
were moved to rail from the road, it would DOUBLE the freight train
requirement, and there is no way anybody is going to invest in such
infrastructure unless there were coercion or other factors at play. Rail
transport for freight is only of limited economic value because of its
inflexibility, so it's good, for example, for the long-distance transport of
coal, but useless for the movement of 1000 computers being sent to 100
wholesalers in 20 different parts of the country.

Even in Germany, where any significant company had a railhead, use has
declined dramatically...

I am a great fan of rail travel, but not at the expense of economic reality.

FROM DAS: This is I dispute. These days paper recycling is a 'political'
act done to salve people's consciences. A few years ago in the UK a major
newspaper tried paying people GBP 5 for every ton (or was it per 100 kg?) of
paper but the campaign failed as they could not sell it on for a profit.
Yes, our local council also collects paper as well as other items, but it
would be simpler and cheaper to incinerate it.

Try buying writing paper made from recycled paper. It's not as good and
costs more.

The only way to make paper recycling economically viable is not introduce
market distortions, such as taxes on landfills and other ways of handling.

FROM DAS: To many 'ifs'. Forget about 'training'. Even if 99 out of a 100
get it right, just one sheet of coloured paper ruins the batch...

Here in Britain we are always exhorted not to chuck our Yellow Pages
directories into the paper recycling bins (because of the yellow paper), but
how many take heed? Paper is paper, right?

FROM DAS: Even more so here. One brown bottle in a batch of 100 uncoloured
ones is enough to rion the lot.

FROM DAS: I don't get it. White wine (urine coloured?) is always sold in
uncoloured bottles.

FROM DAS: We have versions of this in the UK, the exact format depending on
the Local Authority (municipality). It does not detract from my general
contention that incinerators would be the most efficient solution (you can
also use the heat output for heating, done in some places in Europe). For
things other than aluminium only distortions help, one of these being the
(political) difficulty of building incinerators.

As regards glass, the raw material is infinitely available, and I have seen
the energy balance.

Try speaking to people in the recycling and incineration business.
