Kero Electric Scooters in NZ

I just stumbled across this site for electric scooters available in NZ. Looks like its a reletivley new business as half of the pages of the website don't work.

# Range of up to 80 km on one charge
# Top speeds of 55-65 km/h
# Travel 5000 km for 25 dollars
# No emissions and noise free
# Say farewell to parking fees and oil addiction

Collaborative transport

These SWARM bots have been programmed to work cooperatively to move larger masses. Relates back to the idea of trailers and having a driving force with a series of non-driving forces.

Infrastructure Documents

I have been collecting information on infrastructure over the last wee while. Below is a few of the files I have found worth looking at.

Motivate – NZ’s leading transport newsletter (autumn 2006) – Congestion Solutions fro Auckland. This document goes thought the proposal of congestion charging and alternative means of reducing car usage in Auckland

motivate - Auckland Congestion solutions.pdf

Vagverket: Trial Implementation of a Congestion Tax in Stockholm. This document is about the whole process followed for the congestion tax implementation in Stockholm. It includes everything from the reasons why through to how is is implemented with in-car signal senders and payment over the internet.

Stockholm Congestion booklet.pdf

World Transport Policy & Practice. This is a compilation of articles on several different topics to do with urbanism and congestion. The articles include:

- What goes up must come down: Household car ownership and walking for transport.

- Trends, innovative course settings and levels for mobility & transport: Seen in the year 2030. - This article is quite interesting. The author holds a utopian view of the world if it were to progress in environmental awareness levels and development to do with sustainable mobility. (not sustainable transport – think of the difference there)

- Splintering the public realm: Using local public space for corporate economic gain.

- Effects of pedestrianism on the commercial and retail areas: Study of Kha San Road, Bangkok.

- Cycling for active transport and recreation in Australia: Status review and future directions.

- Travel in Inner City Vs Urban fringe of Adelaide: The role of Neighbourhood Design.

World transport Policy & Practice 2030.pdf

Congestion will continue to grow - This is a document that adapted from an address that Anthony Downs (Senior fellow at the Brooklings Institute, distinguished scholar and author) this is his view from 1999 on the increase in congestion.

congestion will continue to gro.pdf

Inrix Real Time Traffic Flow system Factsheet. – Looking at reducing congestion via information fed to drivers of blocked routes etc. I also have another information sheet on a Pioneer in-car unit that does the same thing as this.

EEStor

i discovered this company when i was researching super-capacitors. they're very secretive but have recently come out claiming they've invented a new energy storage device which is a 10x improvement on the lead acid battery. from what i can gather its essentially a super-capacitor, but much better. there seems to be very little info on them but heres some interesting things i found.

the initial speculation - www.treehugger.com/files/2006/03/eestor_capacito_1.php

what EEStor has to say - www.treehugger.com/files/2007/01/big_news_eestor.php

So we can get an estimate on what electric motors weigh see if you can find examples to post or bring along for tuesdays meeting. Chocolate prizes for the best power/weight ratios in 250 watt category, 500 watt category, and 1,000 watt category

Super Caps

Super caps, or "capacitors" are an alternative energy storage to batteries. I don't know quite how they work- ask Andrew or Chris if interested- but from what I understand they are lighter and deliver higher power bursts for acceleration. However, this comes at a cost- they don't hold as much energy, so they don't last as long. there is also rapid dissapation when not in use. On the plus side they can be charged very quickly which is why they are used in regenerative braking. Very useful things.

Carried away?

Hi guys,
I've spent the last few days looking through some new sites. The first is
The Transport Research Laboratory ,
or TRL. They are UK based so much of their information is for developed countries but they have a section on developing countries, and sections on saftey and environmental impacts are highly relevant. They clearly have a lot of information which would be invaluable to us but they are conservative with what they share, so I've contacted them explaining who we are and what we are doing and I hope to hear back from them soon.

I found a link to them through
http://www.itdp.org/mission.html
or The Institute for Transportation and Development Policy, who have a huge selection of great links, and are involved in projects such as the mass donation of bicycles to developing countries, as well as developing a bicycle specifically for african conditions, ironically called the California bike.

A final word on an article called " Urban Transportation And The Millenium Development Goals" By Walter Hook in the Global Urban Development MagazineMarch. This is also at ITDP under publications. A little long but answers many of my questions on the unique transportation needs of developing countries and reminds me that what we are doing can make a real difference.

Some highlights:

" In Africa, virtually all vehicles are imported, and there are fewer vehicle options, with land rovers, cars, a few paratransit vehicle types, maybe a few bicycles, maybe animal traction, and nothing else. Where motorcycles have been introduced, like in northern Kenya, Uganda, and Burkina Faso, they have been rapidly popularized. This paucity of vehicle types and their high cost is partly because Africa has virtually no vehicle manufacturing, motorized or non-motorized"

"While directly subsidizing bicycle ownership for the poor is generally not necessary, just to keep matters in perspective, it costs US$10 million to construct a single highway flyover. The beneficiaries of this flyover will be mixed, but mostly concentrated among wealthy motorists. This same US$10 million could buy 150,000 good quality bicycles, or cut the price in half for 300,000 modernized cycle rickshaws, creating 100,000 jobs. Put another way, you could give every man, woman, and child in Senegal a bike for US$500,000,000, roughly the cost of 10 kilometers of subway, or of one major highway. Certainly, donor agencies focused on poverty alleviation would be well advised to focus on bikes and not on highways.

This is not, however, the best approach to resolving the vehicle supply problem in Africa. Most important is to introduce competition and attract private sector investment into the African vehicle sector, both motorized and non-motorized. Joint ventures can be developed that demonstrate the existence of a robust vehicle market and then gradually induce private suppliers to shift to Africa a greater share of the value added from the production process. Greater market involvement in the transport sector would help to break down local vehicle import monopolies and engender competition among suppliers.
The Institute for Transportation and Development Policy (ITDP) has been developing interventions in the non-motorized vehicle supply sector in Africa, where the vehicle costs are most affordable to the poor. The California Bicycle Project, initiated by ITDP in cooperation with the Trek Bicycle Corporation, developed a bicycle specifically designed for urban Africa, and branded it the “California Bike”. By consolidating orders from small independent bicycle dealers, donor agencies, governments, and large employers, ITDP was able to reach sufficient scale to ship container-loads, reducing freight costs and unit costs. The scale of the orders allowed ITDP to negotiate orders directly with factories, bypassing the usual middlemen. In the first order, 1,920 bikes were procured. All were sold, and a 16 percent rate of return was realized. There are now 35 independent bicycle dealers acting as distributors. A second order of six containers arrived in Africa in the summer of 2005. In this way, the California Bike Coalition has been able to introduce a good quality affordable bicycle into Ghana, South Africa, Tanzania, and Senegal at prices between 25 percent and 50 percent below the cost of any bike of equivalent quality.
By working to overcome market failures in the vehicle sector, rather than simply donating vehicles, donor agencies in partnership with global vehicle industries can play a more constructive role in establishing sustainable commercially viable domestic vehicle production. "

I'll contact ITDP as well, I just need to work out my damn Microsoft Passport! Righto, thanks for your time,

Oren

electronic textile link

Here is a link to one of many recent reports on electronic textile development.
Currently, there is an industrial trend to move from conceptual prototypes or underdeveloped electronic textiles to products that can be washed and used without impedeing on their durability and performance. This article establishes that such developments are underway, and also briefly outlines some of the prospective uses for electronic textiles- military, medical, sporting/human performance gauging..... automotive uses are not mentioned here, but with the close human to machine interface of transportation, especially with regard to small personal two wheelers etc, smart/electronic textiles could offer all manner of solutions:
-combining communications and safety
-compactability
-water proofing/resistance
-wearability!

It may provide a platform with which to 'tap' energy produced by the human body to be stored and used in conjunction with a battery pack as power..?

-low-zero emmission

It could also include aerial/antenna devices for tracking systems safely contained in a jacket or glove etc.
Such a garment could works in conjunction with a transportation device via blue tooth etc.

Shapeshifter - resource optimisation

Shapeshift is another business that is operating under the Canterbury Innovation Incubator

This kind of technology may be handy for optimising the amount of resources we wish to use if we were considering cutting frames from a single piece of material. It may also be handy for Kate as far as safety clothing goes.

Have a look at www.shapeshifter.net.nz

Blurb from CII site:
Shapeshifter provides optimisation software for manufacturers in the apparel industry. The founder, Dr. Hamish Dean graduated from the University of Canterbury with a PhD in mechanical engineering, having developed a mathematical optimisation algorithm capable of manipulating 2-Dimensional objects in software such that they can be rearranged in a more closely packed formation.

This technology allows savings in raw materials of 1%, converting to an impressive 10% increase of profit for apparel manufacturers. This kind of improvement can save large sewn-goods manufacturers millions of dollars in raw materials each year. Furthermore, new opportunities in diamond cutting and 3-dimensional object manipulation have been trialled with impressive results

Cyclist Wattage

For Your Information

The average "in-shape" cyclist can produce about 3 watts/kg for more than an hour (e.g., around 200 watts for a 70 kg rider), with top amateurs producing 5 watts/kg and elite athletes achieving 6 watts/kg for similar lengths of time. Elite track sprint cyclists are able to attain an instantaneous maximum output of around 2,000 watts, or in excess of 25 watts/kg; elite road cyclists may produce 1,600 to 1,700 watts as an instantaneous maximum in their burst to the finish line at the end of a five-hour long road race

New direction to consider

To extend thinking further we should now change scale ( think small ) are there delivery systems in place currently at different SCALES to our current thinking?

Maybe we should be looking at a macro cluster of like devices that form a delivery system ' networked ants ' interconnected, able to work together or appart.

What’s being delivered?

With delivery being cited as a key contributor to city congestion, is it possible to reduce the size of delivery vehicles by delivering in bulk rather than in individually packaged items requiring further transport to remove waste?
An example is bottled drinking water or other liquid consumables. Can design provide a bulk package that allows a consumer to purchase a small quantity without compromising the safety or freshness of the product? Could a tourist visiting New Delhi confidently have a water bottle filled from a bulk supply or from a piped container that had been purified on site? Could the fizz be kept in a coke with a bulk supply product? Do the world a favour and get rid of the later all together.

Chris F

An Holistic Approach

Following several meetings discussing the various collaborators views and different solutions for the pressing problem of city congestion and on-gong depletion of resources, it seems apparent that no one solution is likely to address the problem and that an holistic approach is most likely to develop integrated concepts with real life applications.
My investigations have focused primarily on vehicles and I have found a number of interesting sites on electric hub motors. Hub motors are available as a simple bolt on conversion for standard bicycles through to sophisticated applications as with this mini which uses hub motors to create a hybrid car that can achieve impressive results as shown.

The issues with electrics are obvious however; the need for charging large banks of batteries over a long period of time may make them unattractive. Perhaps it is the charging process that should be looked at. If this mini can use regenerative braking to assist with battery charging, maybe the same process could be applied to other wasteful braking systems such as lift brakes in multistory buildings. If some key large companies that required delivery services were to collaborate to provide battery banks for small delivery vehicles, low batteries could be swaped with batteries charged from energy that would have been wasted and be providing a delivery service for the building itself. Battery technology is moving forward and smaller, faster charging efficient batteries are on the horizon.

Ants

Urban Goods Transport: The Involvement Model, based on - Ants

Imagine a world in which you never walk anywhere empty-handed, because you are always taking somebody else’s stuff along. You would have been handed it by another person, and you may need to give it to somebody else along the line before it reaches its final destination. That way, Pizzas get delivered, cats taken to the RSPCA, letters taken to the mailbox, blood samples taken to the labs, etc.

This would require three things first:

A trusting population.
A system of coordinaton.
An acceptance of the system’s value.

Here is how I suggest to solve these issues:

“A trusting population”:
If every object and every person in the world had an inseparable tracking device visible to satellites, any irregularities would be trackable, and thereby discouraged.

“A system of coordinaton”:
This would work very much like a ride share database. People would input the travels they intend to make and the transport capacities available to them in a database, which would then automatically book meeting times and places for object hand-overs, possibly in multiple form to accommodate possible cancellations or other occasions of non-meetup. This could happen entirely via email and mobile phones.

“An acceptance of the system’s value”:
The population would need to see that what goes around comes around, and they would, because as much as they carry things all the time, people give them things they ordered whenever they do. If anyone is ever identified as having provided too much service, credit will be given in the shape of being excluded from the service providing loop until the balance is clear again. As this system would do away with things such as delivery vans, petrol costs, depreciation for trucks, etc., prices would go down significantly for many things, and delivery traffic would be reduced to a mere trickle.

Helium

Hi guys,
this is an opportunity to put in a dream of mine which I've been fostering for over 25 years. Long story short: How do you feel about a vehicle which basically maneuvers like a helicopter, using four small rotors, and which is floated with helium tanks to a degree of about 80% - making it a heavier-than-air "mini-blimp", whose weight is reduced by the helium tanks to such an extent that four modest rotors, powered by only one, centrally mounted pressurized-air driven motor and a motorcycle chain, suffice to lift it.
It would be like the Jetsons, but come true with low-tech available even to the Victorian age - well, not quite, but make it Edwardian. So, this is not difficult to do. I'll try to add a pic to make it clear (may take a while, it's at home).

Welcome!

Hi all, welcome to our blog. This is our 'primordial soup', a place for our ideas to meet and grow. Please post anything you have been working on or perhaps has caught your interest.

Looking at inner-city mobility in developing countries there are a number of problems that need to be addressed. Congestion and pollution are paramount.

I've mostly been looking at alternative transport infrastructure such as light rail, tram-like power sources under the road to support personal vehicles, gondola or ski-lift networks for small packages, or a way of harnessing the energy efficiency inheirent in pendulum motion, perhaps one day flying through the city like spiderman. An alternative or supplimentary infrastructure excites me because conjestion can be reduced radically, and these countries could end up leading the way.

Oren.
