Had the same thing just before Christmas on my '64 Mog Traveller.

Just approaching our local town and 'something felt a bit odd' - 'go'
pedal hit the floor and engine revs went up! Floor the clutch, kill
ignition, hit hazards & find a space on the side of the road.

Turns out the throttle return spring (probably original) had lost the
hook on the end (they just don't make 'em to last! g)

Managed to bend a new hook on the end, then into the local farm supply
shop for 'A spring about that long'. Couldn't help but grin when the
lady behind the counter said - 'Certainly - compression or extension ?'

Quick rummage in the box of shiny new springs - and one Euro later -
and we've not only got a new spring - but we've got a new spare spring
as well! I love old cars!

They are, but easy enough to convert. Toyota just designed a car to take
advantage of the poor way official mpg figures are calculated. Which was
ok as a *comparison* between basically similar power plants - but not for
a radically different design. As those who bought them soon found out.
It's also probably fine in the US as a town only car - but too large and
expensive for that role in the UK. And was truly terrible as a general
purpose family car in the UK.

I've no objections to hybrids in principle - and they are getting better
all the time. Just object to fraudulent claims about what they can achieve
- and of course those who believe them without question.

That's probably why I don't really see them around here - sure, we have
most things available in town here, but the distances involved to get
to the more interesting stuff (or visit relatives etc.) are typically
quite large.

Personally I worry about the longevity of them without expensive

with modern IC-engined vehicles, too. I don't mind stuff wearing out, but
I do object to it when it's uneconomical to fix the problems and it ends

The Prius mpg claims in the UK were correct as mine did what they said. The
US mpg tests are different. The new Prius is even better again.

Once the Vauxhall Amera (Chevy Volt) is out using a series-hybrid setup all
will adopt series hybrid. Tests at GM are giving it 60mpg running off the
genny set alone. The car is driven by electric motors only.

The Prius is the most reliable car in the world - JD Power and me. The
Prius is simple and has less components than other cars. It is super smooth
and quiet and a joy to drive. The Prius batteries are expected to last 12
years and warranteed for 8. After 12 years if the batteries need replacing
they will be cheaper and far better as batter technology has moved on a lot.
The cost of replacement right now is less than replacing an auto
transmission. When you replace an auto transmission you are back to the same
point. Replace the batteries to an advanced set and the car is improved
greatly having new lease of life.

They will be on the roads for eons.

I'd like to bet that in fewer than 8 years there won't be a suitable

Looking at secondhand values shows what a poor buy the Prius is. They
depreciate faster than if they had been pushed off a cliff. And they're
remarkably poor VfM even then, since one is buying a car with a battery
that can cost £1000s to replace. An Avensis diesel has similar mpg
claims (and much better real-world mpg) and it's a larger, more
practical vehicle than the laughable Priapus.

I would have thought that the one thing that is likely to be available
is replacement batteries. A failed transmission might be a different
matter.

But the point is well made with regard to all cars; when I was young
they rusted away before they wore out, or if they wore out replacing
engines and transmissions was relatively cheap. I've been told, and
quite believe it, that the cost of replacing the CVT transmission on a
Honda Jazz (I owned two, brilliant cars) is such that on a 7+ year old
car it's economically a write off.

1/. Quite a bit. Especially for windpower which is not generated where
its consumed. Prces range from aboutr 1/10th of teh generation capacity
capital cost for a nuke, to aboiut 1/3rd or ghgher for offshore
windfarms. The 'african desert powers Europe' scenario places the
transmission costs at or above the generation plant build.

And that doesn't even cover the overnight storage required.

times as much for.

My renewable favourite is tidal power (*not* tidal barrage, let me make
it clear). Take your windmill, turn it upside down, and stick it in the
water. Tides happen twice everyday, everywhere, and, conveniently, at
different times around the country, thus evening out the power generation.

My niece who is in the renewables business, does emphasise to me that no
single renewable solution is going to be a magic bullet. Not wind, and
not my tidal jobby.

It's gonna have to be nuclear (and should have been all along).

I thought the tidal ones were (taking a rather simplistic view)
essentially big float - pivoting axle - gearbox - generator?

In other words, the only bit in the water is the float, with all
the serious gubbins above the water level. Not that there aren't
issues with salt spray, I'm sure - but I'd expect it to last a lot longer
than some kind of undersea windmill.
