I'd always thought that VW should have made a diesel hybrid (before
their recent testing antics, that is). A hybrid diesel running on
biodiesel or waste vegetable oil would check all of the boxes for
self-righteous environmental types around here.

I had, among other autos, a Nissn Micra. I loved it dearly, and made provisions
for pushing back the drivers seat for room. One thing I discovered was not to try
to stop quickly from a high speed.

I used to farm. They used to estimate that you could grow enough fuel on 15% of
the area of a mixed use farm to keep the farm in power. That did not include the
power needed to build new tractors

So a Land-Rover V8 can't pull anything?

By the time it's been through a hybrid transmission the torque
characteristics of the engine don't matter a damn.

Come to that I've had petrol cars with towbars that would quite happily
spin their drive wheels...

The legend of torque and towing is just that. A legend. And like many
others it has no basis in fact.

Very interesting link, thank you. I especially like the last sentence:

"Breeder reactors could match today's nuclear output for 30,000 years
using only the NEA-estimated supplies."

"Today's nuclear output for 30,000 years", when you add 30,000 new
reactors, does that drop to 1 year?

What has a Landrover V8 got to do with anything? (Thoughts of Tina Turner}

I drove a Land rover for years as part of my job, and only sold it because
the drivers seat could not be adjusted. A Defender with an Austrian 5 cylinder
engine. Anything else was only a ponce wagen

As we have 439 reactors currently I presume that gives us 439 years
until we have to find a sustainable solution or take the 90% population hit.

Of course there remains the problem of NIMBY^30000 which is likely
insurmountable especially when added to the detail that breeder reactors
are weapons technology which in widespread use would make weapons grade
fissionable material widely available which will add NITBY to NIMBY.

Those 439 reactors produce about 400 GW of electricity. The world
currently consumes 20 TW of electricity . To replace fossil fuels
(absent renwables for argument sake) with nuclear, would require
19,600 additional reactors (at 1GW each); and given the
amount of time necessary to build such a large fleet, by the time
it is complete worldwide consumption will have increased by 50%
at current 2.3% annual growth rate, so closer to 30,000 new 1GW
plants would be necessary.

Fundamentally, we cannot continue to grow energy consumption by 2.3%
annually for much longer. And given that capitalism requires annual
growth, in its modern incarnation, the global economy must transition from
growth-based to steady-state. That's gonna be hard.

Yes that's the basis behind saying that if we have the fuel to run
those 439 for 30k years (claimed for breeder reactors upthread) then we have
the fuel to run 30K reactors for 439 years and then we need a real
solution15

Personally I think we have a better chance of building the 100K or
so million litre flow batteries that we'd need to run everything off
intermittent sources.

True, the real question is how much energy consumption per capita
can we sustain and what can we do with it.

Yes it is, but that growth is only essential so that the money
manipulators can cream off their cut for doing nothing productive.

It's not just the energy per capita, but the number of people.

In 1800 the world population was less than a billion.
It's now over 6, and still growing.

If we don't get that under control nothing else matters.

We pulled a travel trailer (caravan to those across the pond) with a
1962 chevy impala (gasoline/petrol). Maus' experiences in Eire don't

No, It's not. In certain ethnic groups, it's actually falling quite
rapidly. China is Falling, Iran is Falling, ethnic Russia its falling
Nigeria is is rising rapidly. Citizization (new word) is growing, and
anyone touring rural France, Scotland and Ireland can see it happenin.

Go along any road, anything pulling anything is diesel. (Or Deisel),
I can't remember. The EU parliment has decided that all deisel will
be stopped by 2030. Just goes to show, all the idiots are not in the US.

Well, it is over 6. Currently 7.9 billion, so pushing eight

And it's still growing in the world. Some countries (Japan
springs to mind) are decreasing. And the growth rate is
decreasing worldwide, but it's still growing.

The expectation is we'll reach 9 before it starts declining.

It's my understanding that even the British have accepted the
American definition of billion at this point in time.

One could agree about that. How does anyone know how many there is?.
Who counts the counters? Japan, I suppose, is a pointer, reportedly
boys spend most of their time in their rooms, looking at games and
porn. Also the highest use of adult nappies. There may a correlation
between adult nappies and condoms :):)

The girls spend most of their time on smartphones. I don't know any
way of becoming pregnant by smart phone (The mind boggles). It may
be on alt.risks.
