White commuting is another reason for wanting cycletubes in urban areas

16 Replies

It snowed yesterday. About half London took the day off and my cycle to work took twice as long. When I set off  home the back roads were covered with icy ruts. After about 20 minutes of precarious travel I came level with a bunch of 25 teenagers wearing hoods. They moved into the road and surrounded me as I drew level. Then they pelted me with icy snowballs. I wobbled, stayed upright and had to stop to dig the snow out of my ears. My wife asked why my voice sounded hoarse when I got home.  ‘Too much bad language at full volume’ I explained. The kids, no doubt,  were just having fun – relieving the ennui of urban life – but they made me wish God would release a sheaf of thunderbolts. Sadly, the morning news had nothing about lightning-strikes on groups of hoodies in South London – so I have another reason for wanting cycle tubes for green communters. Meanwhile, I will learn the rest of the poem:

Cannon to right of them,
Cannon to left of them,
Cannon in front of them
Volley’d and thunder’d;
Storm’d at with shot and shell,
Boldly they rode and well,
Into the jaws of Death,
Into the mouth of Hell
Rides the poor cyclist.

Effective policies re global warming, climate change, urban design, sustainability and landscape architecture

Scotland's Old Red Sandstone was laid down in hot, dry, arid conditions - about 400 million years ago. Homo sapiens evolved about 4 million years ago and is not responsible for this climate change

Scotland's Old Red Sandstone was laid down in hot, dry, arid conditions - about 400 million years ago. Homo sapiens evolved about 4 million years ago and is not responsible for the climate change from hot arid desert to cold wet coast.

The expert science behind the theory of global warming is unimpeachable and unchallengable: thermometers show temperatures are rising and tape measures show glaciers are retreating. But several important questions have uncertain answers:

  1. What percentage of global warming is caused by burning fossil fuels and felling rain forests?
  2. What percentage difference would result from the measures advocated by reasonable scientists?

The answers to these questions would be useful. My guesses are (1) humans have caused only a small percentage of the global warming in the last 20,000 years (2) the measures currently under discussion, though I am in full support of them, would have next-to-no-effect on climate change. If we are serious about doing whatever little we can do to lessen climate change then we should consider the following moderate measures:-

  • Stop world leaders from wasting their time and our money on conferences in Kyoto, Copenhagen etc, or, if this proves difficult, make them spend their time using Copenhagen’s wonderful bicycle network instead of its limousines, its cavernous conference halls and its spikey cocktail bars
  • Ban the consumption of meat
  • Make it illegal to drive children to school – at any time in any country
  • Stop wasting hydrocarobons on road transport and air travel (making every place a holiday destination would help)
  • Stop war and stop making munitions and use the money to build giant solar energy farms in dry deserts
  • Extend Chinese population control policies to Africa, along with its mineral resource policies
  • Use  suburban gardens for home-grown food and vegetables, especially in America and Australia
  • Facilitate voluntary euthanasia
  • Legalize heroin, cannabis, cocaine etc – to get more tax revenue to spend on protecting rain forests – and stop the waste of resources on ineffective drug enforcement policies in rich and in poor countries
  • Vegetate most walls and most roofs in most cities of the future
  • Put 300 mm of insulation in most roofs, floors and walls
  • Train more landscape architects and urban designers
  • Replace the World Bank and the UNDP with Jamie Lerner
  • ‘In the prison of his days teach the free man how to praise’ (W B Yates)

Green vegetated roofs in the theory of landscape and architecture

Ecological space + a little social space: Green roof on California Academy of Sciences

Ecological space + (a little) Social Space (Green roof on California Academy of Sciences)

In Germany, vegetated green roofs are often classified as:

  • intensive (ie treated as a garden, typically with exotic plants, irrigation, turf and social use)
  • extensive (ie treated as habitat, without irrigation or maintenance)

I prefer to look at green roofs from a more Vitruvian standpoint and consider their roles as:

  • visual space [Delight]
  • ecological space [Firmness]
  • social space [Commodity]

” This 5 story facility sweeps a wooded corner of the campus with an organic, vegetated form that blends landscape and structure, nature and high-tech and symbolizes the creativity it houses.”  The  green roof is open to the public and, like the roof of Australia’s Parliament Building in Canberra, is surfaced with mown grass. Image courtesy teddy-rised It is  not ecological space:  the grass is irrigated and  mown. The building was designed by CPG Consultants.

Elevated cycling tubes for green commuters

Proposed london cycle tube

Proposed london cycle tube

I published the above image in 1996 with the comment that ‘At some point we may be able to have a network of plastic tubes, with blown air assisting cyclists in their direction of travel (Figure 7)’.  The photograph was taken in Greenwich station and the ‘slot’ where the cycletube is shown has since been used to build an extension to the Docklands Light Railway (from Lewisham to Canary Wharf). I like the DLR but, still believing London needs an overhead cycletube system for green commuters, was delighted to hear a comparable veloway has been proposed in Canada (see illustrations below).

The user experience in a pneumatic cycletube would be sublime: quiet, beautiful, self-directed transport. There is an overland railway line from Greenwich to London Bridge. Bowling into the tube at Greenwich one could almost stop peddling and be carried along by air, gazing at the London panorama. Everyone would have a seat. Nobody would have to wait for a train. Journey times would be faster than by train because there would be no waiting and no stopping and no delay in exiting the station. One would glide from exit into the heart of one of the world’s greatest cities. relaxed, warm, dry and filled with the joy of life. There would of course be twin cycle tubes, with the bicycle flow and airflow in different directions.

Cycletubes could also help families negotiate difficult junctions and give them safe routes to school – though the tubes would obviously have to be integrated with the urban design.

Zen: garden as house

Apart from what looks what looks unfortuneately like artifical turf on the roof – the Garden House by Takeshi Hosaka Architects with its tight triangular plan is a surprise and delight! Definitely a garden for my soul! The living spaces are designed around the edges of an enclosed garden courtyard, cleverly stacked and arranged to take advantage of every square mm of space, create privacy and capture views. In the photographs the garden is very young…it would be fantastic to revisit the house as the tree grows and the potted garden matures.

If you can’t resist viewing more  maybe a trip to Japan is in order…
