6 FEB 07. NOTE TO JURGEN AND THE PYTHONAUTS: I wrote the article
below last month, but then decided to hold it back as being a) too
long, b) perhaps not quite on topic, and c)maybe contentious. But
reviewing it today, I still think these things need to be said. So,
with apologies for my tendency to run on, and further apologies to
any toes I might be standing on, here it is--
Siwmae pawb,
I guess subscribers to this list don't need much, if any,
introduction to the subjects of Peak Oil and Climate Change. But I
thought I'd pass along a link to an interesting item on the Energy
Bulletin website. It's called 'Joyride To Global Collapse:
Reflections On Kunstler's "Home From Nowhere"', by Jim Minter. It's
one of the 11 January postings at www.energybulletin.net
The point to bikers of this posting (and of many other clear-seeing
peeks into the near future that Energy Bulletin hosts) is the crucial
interest that practical alleweder velos are going to raise - perforce
- in the very near future. It seems to me that a lot of people are
going to be looking into velos, because practically speaking it will
be their only realistic choice for short and medium range transit,
with respectable freight capacity as well; once mass car-ownership
has crashed, that is, and cheap fuel is a thing of the past. (Did you
hear that - at bloody last! - sales of sucker-trucks in Britain - you
know: two-ton, three-litre, four-wheel-drive, five-miles-per-litre
posing-pouches for the ecologically inadequate - has started bombing
at 15% a year. 15%! Yeah!! Make it 30% in '07!)
If - no, WHEN - Henry cracks the self-righting leaning trike, with a
little help from other listees, the next step (one that interests me
mightily in mighty rainy Britain) is the practical, everyday
all-weather, ultra-lightweight, damage-recoverable fairing. In fact,
this is one particularly fascinating project that I've been working
on for a while now - mainly in the drawing office of the mind's eye,
but with some actual hands-on investigations into candidate
materials. I particularly like the soft, flexible closed-cell foams,
that can take considerable impact, deform, and then spring back
without serious damage. (But of course, all of them are
petroleum-derived. Hmmm...)
Seems to me that, whether subscribers realise it or not, Jurgen's
list is something of a spearpoint in this trend towards more velos on
the road, in practical use. We have the swiftly-growing practical
experience of the use of python-form FWD, to complement the
flevo-form, and now the development of a back-end which, already, can
accommodate effective, cheap and simple tilting trike designs (Bram
Smit's and Paul Sims's, f'rinstance) and it seems that any time now
there'll be a self-righting facility on offer too.
In Jim Minter's 'Joyride' column, he points out just how practically
difficult it is at the moment, at least in N America, to live
car-free. That's my experience too, during the two attempts I've
made, even in much more conveniently-organised Britain. Now, two
months into another car-free stint, in Winter, I find that the one
thing that constrains me more than anything else is the lack of
really effective protection from rain and road filth when the
weather's harsh. Yet since he developed the Leitra, I believe that
Carl-Georg Rasmussen has been car-free for much of his time. We stand
on the very edge, I suspect, of a lot more people starting to live
car-free, even amongst the hitherto Pampered Twenty Percent of the
world's human population. Because they must; no option. Some time in
the next ten years, this is going to take off, as it did briefly in
the early 20th century, with the Mochet velos and others.
Behind all the idiot posturing of the politicians and bigbiz
spokespeople and their corporate-mediawhore stenographers, there's a
fascinating grass-roots ferment going on, only reported on the Net
and other fringe media, as lots of people who've seen which way the
wind is blowing start to develop practical, local community solutions
to the growing crisis: The commoners ahead of their 'leaders' again,
as often happens.
Incidentally, Jim's original posting of his column was on 5 December,
1996. Read it now, and marvel at how prescient he was, particularly
about the price of oil, up and down like a yo-yo, but with the
underlying trend remorselessly upwards. He's also wonderfully lucid
about how everything else in our hitech society, including
'alternative, renewable' energy systems, floats on a big
petroleum-energy subsidy.
That idea does give me one problem, though, to which I can think of
no answer: All our bikes and bents assume reasonably smooth, hard
surfaces to run them on. Nothing about the growing energy crisis
suggests that somehow, magically, road maintenance will by exempt
from the crunch. (Tarmac prices have been rocketing everywhere in the
past few years) I spent yesterday afternoon with my partner, she on
her horse, me on my ATB, riding what's called here a 'green lane',
meaning an unclassified country road with the sort of gravel and
quagmire surface that must have been common before the widespread
advent of tarmaced roads, at least in the over-rich countries. A
seriously-different biking experience.
So can we re-invent an updated version of MacMillan's 'Boneshaker'
bicycle, to run on the mid-Twenty-First Century's reprise of early
Nineteenth Century roads? And can we build effective velos using only
neo-traditional wood technology, and the steel technology of modern
small-scale blacksmithing work? Can we continue to expect to have
rubber tyres, with pneumatic tubes? MacMillan and von Drais only had
iron-rimmed wooden wheels, I seem to remember. At the moment, every
single part and material that we use to build bikes, plus the tools
to build them, also float on that petroleum-energy subsidy - just as
the global petroleum ebb-tide is setting in.
Still, at least delta full-fared leaning trikes are a bit simpler to
engineer, and therefore cheaper and lighter in principle than
tadpoles. Yet at the moment all successful velos offered for sale in
N America, Europe and Australasia are tadpoles, I believe, and none
are leaners. Seems that there are important breakthoughs actually
being made at the moment in velo tech, many of them by subscribers to
Jurgen's list.
Anyone who's seen Frederik van der Valle's Master's thesis: 'The
Velomobile As A Vehicle For More Sustainable Transportation' (VERY
highly recommended) will have seen that really striking picture of
TWENTY SEVEN!!! velos lined up beside one COMPACT car, the weights
being about equal. Frederik also has some really insightful things to
say about the social/psychological component of technology, often not
noticed at all.
History is being made, I suspect, by the members of this list.
Hope you're keeping the archives safe, Jurgen. The practical,
how-I-did-it material generated by the pythonauts will, I surmise, be
pure gold hereafter.
Incidentally, if there +is+ anyone on this list who still has doubts
that world oil - and probably natural gas - production has peaked,
and that the consequences will be serious and soon, especially in
Europe and - above all - in N America, then Jim Kunstler's article in
the online edition of the Jan-Feb 2007 'Orion' magazine:
http://www.orionmagazine.org/pages/om/07-1om/Kunstler.html should
help. And there's an ocean more of such insightful material, by many
researcher/commentators, if anyone needs help to locate it.
And hey! Don't Henk's pictures of 'Why I like the trike' say it all........
Cofion, Rhisiart
