Trains & Trolley buses - Transport of the Future.

June 30th, 2008

Can we accept the message that Gaia is sending us about her state of health and what needs to be done if we ourselves are not to be shown as little more than a footnote in galactic archeology as the instigators of her death by poisoning and asphyxiation? Is this to be our legacy?

Last month I wrote about an optimistic project being carried out in the city of London England that can show the way to all other cities around the globe in the field of self sufficient energy production, small independent power/heat source production units scattered right through the city and eliminating altogether the need to be “hooked up to the grid”.

What I would like to talk about here in Australia is an urgent, critical need to start re-claiming all the neglected rail lines throughout our sprawling landscape to allow the freeways to gradually fall into neglect - except for those parts needed to carry future trolleybuses that must over time replace our cars and buses. One grand ambitious rail building project, completed just a few years ago, joined Adelaide to Darwin and is now forming an extremely important funnel for a large percentage of our exports and imports through the port of Darwin. Prior to this section of railway being completed there was nothing between the two cities except a military link of bitumen built by the Americans during WWII which actually finished at Alice Springs so that there were only dry desert tracks for several hundred kilometres till you reached Quorn (A small town just north of Adelaide) I well remember the trip I made on my trusty Triumph Thunderbird motorcycle in 1950. I completed the Darwin to Alice Springs leg of my journey of 1000 miles in exactly 13 hours - yes I was stupid young fool - I know.

Anyway enough of the reminiscing. I am convinced that the present oil shortage problem presents us all with some marvellous opportunities to start heading in the correct and most efficient direction as far as our transport situation is concerned. We must wean ourselves off oil as quickly and completely as is humanly possible if we are to save our planet from being choked to death. For our long distance haulage rail is the only sensible answer. Rail can also be used to help redistribute populations and industry more efficiently. For commuters in the cities light rail and trolley buses can greatly reduce our dependence on the car.

Reports in today’s press highlighted the lengthy delays encountered by commuters from the north west of Sydney - in some cases a one and one half hour trip from Castle Hill to Sydney centre which 4 years ago took only 45 minutes. A rail line linking Pennant Hills, Richmond, Penrith and
Liverpool could eliminate inefficiency of the a bove and induce commerce and industry to re-locate out in these areas where the working population is already concentrated. Such action, however, requires vision and foresight on the part of the present State government and this unfortunately is a quality which seems to be sadly lacking among our present political incumbents.

Some Hope on Global Warming

May 31st, 2008

A fascinating news item in a specialist TV program on ABC TV last week held out a very pleasing prospect which could prove a major weapon in the world’s struggle to slow down the pace of global warming - or more particularly the release of carbon dioxide into the atmosphere.

In the City of London in England, one man has been given the task of helping reduce its carbon emissions and providing the necessary energy to allow the city to continue functioning while reducing its carbon emissions by 60% by the year 2025. This would seem an impossible task and yet engineer, Alan Jones has been given this task and has accepted it. His previous work on providing sustainable energy for the city of Woking gave him the necessary credentials to be saddled with this job.

At Woking Alan Jones arranged for the construction of 80 individual “in house” power stations which have made Woking independent of power from the national grid. Electric generators operate using natural gas and heat from this operation is piped underground to supply heating, hot water to nearby residences as well as the building itself. In addition the total roof area of the building is covered with the very latest in solar electric panels. So the whole building is Combined Heat and Power station - plus a large carpark.
In fact, however, generating electricity and heat together within the city is not new, Manhattan was set up with CHP (or combined heat and power) in the late 19th century, but when modern, centralised power stations were invented, CHP was quietly abandoned – and the city was linked to the grid.

In energy terms, though, massive centralised power stations are far less efficient.since more than two thirds of the energy produced is lost to the atmosphere as heat – with further losses over the grid. They just generate electricity, throw the heat away, and the gas companies and/or oil companies provide fuel for people’s boilers. So not only are they throwing energy away they’re using another lot of energy to do something that could have been done from the waste heat. It’s just a complete waste of energy and one of the primary causes of climate change.

The town of Woking is now producing 80% of its own energy. And in just 10 years it had dropped its CO2 emissions by a mind-boggling 77%

The goal for London’s climate change action plan is to take twenty five percent of its energy supply off the grid and onto decentralised energy by 2025, and more than fifty percent by 2050. A huge changeover to decentralised energy.
Planning permission now requires that all new developments in London have to include 20 %, decentralised, on site renewable power.
But London’s action plan also tackles retrofitting – which you need in a city that’s packed with historical treasures.

Of all the measures in the city of Londons’ climate action plan – transport, homes, new buildings - CHP generation of heat and power is the one that can actually deliver on the 60 - 80% carbon reductions required.
Its like an energy revolution. It’s almost like comparing the mobile phone to the landline.

Finally, as if the massive job of installing hundreds of CHP stations was not enough challenge, Allan Jones and his team identified through their climate change action plan that probably their largest renewable energy resource currently untapped is restaurant food and organic waste, vegetable peelings. If all the organic waste in London were converted to biogas and fed into the CHP units, there’s enough to power 2 million homes – that’s over half the homes in London. So waste disposal now becomes power generation.

It is hoped that London’s call to arms will go down in history as the thing that motivates the rest of the world into a wider survival reflex.

Allan Jones: “If the cities all do the same things as London, that’s how you could tackle climate change. While federal governments are still talking about it, cities can get on and do it.”

“Behind the Mask”

March 31st, 2008

Don’t be fooled by me , by the face I present
For I wear a mask from a large array.
A different mask for each new event,
Depending on whom I meet each day.

Mask number one is a favourite of mine -
Secure, confident, calm and contained;
Need no one, in command all the time.
Don’t believe me please its false and strained.

While my surface is smooth, confusion’s beneath
Fear and loneliness struggle with grief.
Quickly! My mask! I can’t let it show,
My weakness and fear no-one must know.

So with nonchalant mood, carefree I pose
To hide me away from the glance that knows.
That glance which could truly save me if only,
I’d break down the wall that imprisons the lonely
- - - - - - - - me.

But I keep on with the games, my pretences I flout
Scared child within, assured mask without.
My life is a front, an affront to truth,
As idly I chatter, suave and aloof,
of all about nothing, but nothing of all
that’s crying within behind my thick wall

I really do hate these false social rules
So when I start my charade just don’t be fooled,
But listen most carefully, listen please do,
To hear what it is I’m not saying to you.

Deep down I detest phony games, falsity,
I want to be genuine, childlike and me.
So please hold out your hand to me e’en when it seems,
The last thing I want is that you share my dreams.

Meditation & Invention

January 27th, 2008

Some time after completing the meditation course a low stool was constructed which incorporated these principles of weight distribution, balance and movement. Having completed the first model a number of others were constructed and sold. However, it was the realisation that the concept could be applied to full size seating at desks, tables etc. which occupied time, energy and funds over the next four years.
Meanwhile studies in anatomy, physiology and physiological psychology were undertaken to discover those scientific principles, and any research experiments which might help to explain the greater comfort experienced with the Kneelsit as compared with all other forms of seating. Lessons were also commenced in the Alexander Technique and’ closer observation was made of clients posture problems which he encountered in his counseling practice.
. -:
Further research into back problems and their possible origins brought an understanding that two common factors seemed to be relevant with those clients whom he counselled:-
a. Psychological problems, such as rigidly held attitudes, poor self image etc. and that feelings of strain, tension, balance awareness and poor posture were all inter-connected.

b. Persons engaged in sedentary occupations appeared to be more severely affected in many 6ases and a number of them consistently complained of poorly designed chairs at work.
Continuing investigations slowly made it clear that the proprioceptive sense was one which was little appreciated or understood by society in general, despite the important part it plays in our total feelings of well being. Secondly that it has been largely neglected and allowed to deteriorate through poor body use and the undue strain of badly designed seating.
During the development stages of the Kneelsit, checks were constantly made with volunteers of various heights and build to ensure that the angles, distances, height differentials etc, all felt comfortable for the people concerned. No special notice was taken of any ‘norm’ or ’standard’. (except for the standard or common desk height). The most important criteria was that the Kneelsit had to “feel right” for each person when it was adjusted for their particular body size. This is why people find that having taken the time to custom-fit the various adjustments to suit them they rarely have to change it again. However, a word of warning to the unwary. Do not under any circumstances change the settings without first having received permission from the owner.! You can read about further aspects of balance and movement at this page on the kneelsit website.

Meditation & the birth of an invention. I

December 31st, 2007

HISTORY
In 1988 while carrying out research for a paper on meditation and health I
undertook a ten day course of meditation in a technique called Vipassana.

Research had already been made into Yoga, Zen and Transcendental Meditation; there
was, however, no scientific literature published on this particular technique - hence the
decision to engage in the course itself.
The main emphasis in the Vipassana technique is to train the student to fully focus
awareness on all the sensations occurring in the body. As the mind wandered it had to
be brought back to the main task of focusing on sensations. In essence it was a mental
discipline which sharpened and improved the proprioceptive sense. (as well as providing
other benefits)

The course involved sitting in silence for a total of fifteen hours a day apart from meal
breaks. As a result the aches and pains felt throughout the body were quite severe the
worst pains being in the back.
Various devices such as chairs, cushions, low stools etc. were tried and finally a small
stool with half round legs. Being above an exact balance or fulcrum point which
continually moved slightly made a significant difference and all back pain was eliminated.
The main problem remaining was the pain in the legs and knees. Recalling school days
and kneeling in church pews with buttocks resting against the edge of the seat, a padded
moving knee cushion was envisaged.

The mind being free to wander, I began to recall my days in the infantry
during the Korean Campaign. Very heavy loads were carried at that time, spare
clothing, bedroll, boots, rations, ammunition and weapon, probably between 40 to 50
kilograms, yet, no back pain was experienced. The load had been spread evenly
around the body. Heavy ammunition in front packs to balance the bulkier back pack
and all the time you kept moving. Balance and movement were the key features.
Korean porters carried even heavier loads of fuel and ammunition up steep slopes on’ A’
frames of their own design, always, however, their backs were straight but leaning
slightly forward and their knees flexed so that all the weight was carried over hips and
knee joints.

Nevertheless I am still amazed today, more than 50 years on, how they carried those
heavy loads day after day with no complaints.

(I will complete this in my next blog posting)

Meanderings.

October 31st, 2007

I was roused today - perceptions stirred,
By an old, black crow who greeted me
with sly chuckle and cheeky grin in his wide brown eye.
White plastic bag of treasure? clutched in his powerful beak.
“Something good?” I called.
Flapping off - “Worth a grab and a peek”.

A peek at tired grey fences - staggering,
Leaning exhausted in summer’s haze
Caught up idly by the spider of time
Weaving her web of rusty barb.
Criss-cross here, loop there , no pattern, no seeming design,
But serves to catch the human fly
Who dares to cross her boundary.

Females converse in a an ordered group.
Murmurs, comments but no complaints,
Patiently they wait in line.
Till one - a stranger to the group - inserts herself,
Loud bellows, shoves - she stands confused.
Then one with loving patience, generously allows her in.
They settle down again to wait,
To give again, as they have given all these years
Udders full, milk dripping from their teats
Outside the bails.

Dandelions in bloom
Spread golden butter thick across green fields
While Illawarra flame
Extends her jewelled arms in prayer,
Praising creation with her finery.

A rusty length of steel - discarded,
Twisted by fate into pretzel shape
Stands proudly in the ditch.
With silent grace she speaks
“I too am part of God and S/He of me.”

Kisses, quick greetings of three dear friends,
My spirits lift e’en higher still
Than I thought possible.
I tiptoe lightly on the wings of life
New-born, awakened.

Thus stirred today my senses glow
Roused from slumber by this old black crow.
T’was not his raucous call
But the baleful grin in his piercing eye
Which lifted the scales from clouded sight,
And gave fresh vision to glimpse the All
- - - for a time.

Strange thoughts now rise from hiden deeps,
Of Merlin, Beowulf, Odin, Thor,
Familiars, ravens, silent speech.
Child’s nonsense, Myths? Inflation? - - - OR?

Worksafe Australia - report on the Kneelsit

September 30th, 2007

Way back in 1997 I was priveleged to meet up with a lovely lady who was head of the Ergonomics Department at Worksafe Australia - now re-branded as The National Occupational Health and Safety Commission. At the time of our last meeting I gathered ( from what was not said) that there had been some rather heavy internal departmental disagreements and Glena had just resigned. I believe that it was on her very last day of work that she had set up an appointment to carry out an assessment of my invention - the Kneelsit Balance chair. I quote now from her covering letter to the ergonomic report that she compiled for me on that day.

“Thank you for again requesting my opinion on your unique balance seat. The attached comments are based on my subjective assessment of your interesting product.
I have for 5 years managed the Ergonomics Laboratory at Worksafe Australia and during that time the Worksafe checklist for adjustable and non-adjustable chairs was compiled from extensive research. For around 4 years the checklist was used by most large chair manufacturers as
a de facto standard and there was a marked improvement in standardisation of ergonomic stability and design quality during that period.

The checklist was also used as a basis for rigorous tersting by AFRDI, whose staff I trained, for the accreditation of commercial furniture for Commonwealth Government Contract. For the last 4 years I have been a member of the technical committee, and also the accreditation committee for the compilation of the new workstation furniture standards at Standards Australia. This work has led to the recent publication of a new standard for height adjustable swivel chairs and other workstation components.

As the Kneelsit Balance chair is a unique design combining components of a kneeling chair, a fixed chair and an adjustable chair I am not aware of any International or National design standard to which it would comply in its entirety. Hence my comments are based on my experience in testing and designing chairs for commercial use and more especially on the ergonomic and safety qualities for user comfort and health.

Yours faithfully,

Glena Ellitt
MSafetySC BSc GDipEd,
RN MRCNA MESA

Note:- I trust that this covering letter from Ms. Ellitt may help to clarify just why it is that I can not give a definitive answer to those peoplewho ask the question “Does the Kneelsit comply with the AFRDI Standard? . I believe that the numerous testimonials I have received over the years constitute their own form of compliance.

Poor posture

August 31st, 2007

POOR POSTURE

Poor posture is learnt early in childhood and made worse by badly designed school furniture. You learn early on to slouch in your seat to try to overcome the torture of a horizontal seat and a vertical backrest (often set too far back to be of any use or value). Even if you were lucky enough to get a chair or seat close to your size, very often the desk was the wrong height and in almost every case there was no lumbar support whatsoever. Thus the stage was set for you to learn how “not to sit.” If you learnt nothing else at school, your body learnt this lesson very well!

The posture you are forced to adopt when sitting in a conventional office chair (whether it’s labelled ‘ergonomic’ or otherwise) is one where your body is constrained by your trunk and thighs having to form a right angle (90°). What happens when you sit in this position is that your hips bend to 60°, your pelvis moves backward and your lumbar spine flattens out to take up the remaining 30° thus placing an unnatural strain on your muscles, joints and ligaments. This strain is felt most acutely at the end of a long working day as back pain of varying degree and intensity.

The ideal posture when sitting is one which helps to maintain the natural lumbar curve or lordosis of the lower back - this is when our discs, joints and ligaments are under the least amount of stress. However, it is just not possible to achieve this ideal posture using a conventional chair where the seat and backrest are at right angles. When we take up this position there is excessive pressure placed on the lumbar vertebrae of the low back. This pressure will eventually cause lower and sometimes upper back pain.

    Some things you can try to minimise this discomfort.

While watching TV

When your children are sitting in front of the TV, encourage them to sit on the floor rather than in the standard lounge chairs; or buy some inexpensive ‘bean bags’ as these place less strain on young spines.

    At Work.

1. To figure out the correct amount of lordosis (lumbar curve) for sitting with minimum strain, Physiotherapist Robin McKenzie has suggested the following:-(*1)

Sit forward on your chair so the backrest doesn’t interfere while you learn this.

Allow your body to slouch to its maximum and hold that position for a few seconds.

Then reverse this position so that you are sitting totally erect ( the limit of your lordosis ) - again hold for a few seconds.

Repeat several times so that you can feel and understand the difference between these two extremes.

Take up the totally erect position and then allow your body to relax by 10%.

This is about the best sitting position for the lumbar spine (if you can remember to maintain it). Do NOT try to keep up the fully erect position as this will cause pain.

2. Using a wedge-shaped support to gain some forward-sloping effect can offer a stop-gap solution to keeping your back in a more correct posture and relieve some of the pressure or you might try to find some way of tilting the seat pan of your chair forward.

3. Some temporary relief may also be achieved by carrying out regular exercise.

4. In a similar fashion, if you are experiencing pressure on your hamstrings, you may find that sitting with your legs tucked back underneath the chair can often help to bring you some relief.

    At the Keyboard.

You can maintain good posture at your keyboard when:-

Your lumbar curve is at 10% less than maximum.

Your trunk and hips are at an angle of about 110° - i.e. forward-sloping.

Shoulders are relaxed - not hunched.

Your head and neck are in a ‘neutral’ position.

Elbows at about 90° and level with the middle of the keyboard.

Your upper arms are vertical by the sides - not out or forward.

Wrists are in mid position with your hands in line with your forearms.

At Anytime MOVE! MOVE! AND MOVE AGAIN

In addition to excessive pressure on the spine, lack of movement can have quite serious effects on the discs of our spinal vertebrae. So walk instead of drive, take a walk around the block with your kids! Take up Tai Chi or Yoga, learn Aerobics. Just get moving!

Value of exercise depleted

July 31st, 2007

Because of a general feeling of a need for keeping fit in today’s society many people take up jogging, gym work, Yoga, Pilates etc. etc.

How long after completing their physical activity and returning to their desk work is it before they start to feel back pain? Is this connected in any way to their chosen activity? It is not very likely. You can be virtually certain that this aching back is caused directly by the chair in which they are sitting. It has long been known by responsible ergonomists and physical therapists that the conventional chair which is common in 90% of offices today is the direct cause of lower back pain.

A quick glance at the angle provided by the seats in conventional is one of 90 degrees. This angle places inordinate strain on muscles, vertebrae and tendons - particularly in the lumbar area of your spine. The best angle for your thighs and trunk is one of around 110 degrees. This places your spine in its correctly lordosed position and ensures best posture.

Check out kneeling chairs in Wikipedia - these are the only models which allow for this correct angle.

Origins of the Kneelsit chair

June 3rd, 2007

If you are at all curious about the origins and history of the development
of the Kneelsit chair than you would need to go back 3 or 4 thousand years
and give credit to the ancient Maasai who first came up with the idea of making
a milking stool with crescent shaped feet.

Until very recent times milk and blood from their cattle formed the staple diet of
the Maasai tribes. If you have ever had to milk a number cows by hand you will
appreciate what a marvellous device the Maasai milking stool actually was.

Having started out in my youth at age 15 working on a small dairy farm - I think it was
actually my first paid work - helping to hand-milk 40 cows per day. So yes, I still have
vivid recall, or perhaps I should say my back remembers.

Try to visualise a small wooden stool - around 12 inches high, a
bucket clasped between your thighs and your knees in the dirt as you
milk each cow.( BTW in Australia the stool was a 3 legged conventional
one and the floors were concrete.). You started work at 4 a.m. and
finished around 7 p.m.

To summarise, the initial inspiration for the Kneelsit chair was this simple little
Maasai milking stool. It had nothing whatsoever to do with the the backless knee stools which came out some time in the 70’s. As a matter of fact I did not know such animals existed, being one of the early dropouts from the rat race and having retreated to a hidden valleys on the South Coast, office buildings were not on my schedule of places to go.

Once I became fascinated - or “hooked” on the reason why this little stool had worked so
well to eliminate my back pain I began to do some really serious research. This
took me into the areas of physiology, anatomy, psychology, physiological psychology
and then neurology and neuroanatomy.

I believe that the answer to the improvement in people’s assessment of their comfort
level and improved posture is very closely related to the changes in their vestibular
apparatus and it’s stimulation by regular movement which over time will be building
new neural pathways to the motor coordination centres of the brain. What I have referred
to on my website as improving their overall
proprioceptive sense.

So forget the Scandinavians and thank the Maasai!
