A Lovely Night For Open Water Swimming Along The Esplanade In Greenock. 😊

Helen and I walked from Vikinggar in Largs to the pencil. It was a lovely day. This is a photo taken while we were at the pencil looking across the Clyde to Cumbrae and Arran. (at Largs Pencil Monument)

Lovely day - very calm 2 hours before high tide. I did a non wetsuit swim on my own. 675m in 18:24 water temperature 8.6 degC #inverclyde #rwsabc #openwaterswimming #greenock #scotland #theesplanade #clouds (at The Royal West of Scotland Boat Club)

Dome City Blog 1 - An idea for higher density cities

I have been thinking a lot about what we need for new housing and cities. I have been thinking about this for a number of reasons. One reason is that the UK is critically short of housing.  The government and others are keen to see a large number of new homes built.  Personally I support this idea. Another reason was my recent visit to Changchun, China.  This is a very large city by UK standards.  The greater metro area has a population of 7.6 million while the city itself has a population of 3.9 million based on 2010 data.  That was the 5th tiime I’ve been to Changchun and I always enjoy my time there.  However, I think this is a city ruined by the car. I like to walk or cycle whenever I can.  Modern cities, for the most part, make this difficult and unpleasant.  It is difficult because of the distances involved and it is unpleasant because cars and pedestrians/cyclists don’t mix so well. In brief here is the questions I am thinking about and some of the answers that I am arriving at. What if we built a city that was housed in a geodesic dome with a diameter of 1km at the base?  A geodesic dome has the shape of a half-sphere.  It was popopularizedy R. Buckminster Fuller.  I have chosen this structural form because I understand that it is very efficient from a structural engineering point of view. I have some simple back of the envelope type calculations to see how many people this city in a dome could house.  Assume that we made the thickness of the floors separating levels as 1.5m (5 feet) and that we had clear space of 9m (29.5 feet) between levels.  This would provide 48 levels for constructing our city.   The land area at the base of this dome is 0.785 square kilometers (194 acres, 78.5 hectares).  With the 48 levels as described above the land area available within the dome is 25.3 square kilometers (6250 acres, 2530 hectares).   The population density of the the dome were the same as New York City at 27,778 people per square mile (10,716 people per square km) then it could house 271,000 people.  With a lower density of say, 10,000 people per square mile  (3860 people per square km) then it could house 97,700 people.  This lower population density figure of 10000 people per square mile is the almost the same value as for population densities of Miami,Florida and Birmingham, England.   I would suggest that there should be a significant green belt around this dome city.  I would like to suggest at least 500m of park and wild lands around the base (excepting transport links). I will continue these ideas in my next blog. Dome City - Blog 1 5 October 2014 Joe Heffernan

During today's swim there was a downpour. The raindrops on the water made for a fascinating sight. #RWSABC #inverclyde #greenockesplanade #Greenock #openwaterswimming #downpour (at The Royal West of Scotland Boat Club)

Tonight's sunset at the Boat Club.

at Cardwell Bay

As I arrived at the Boat Club for a swim Colin and Gary were just coming back from a paddle to Helensburgh. I went for my swim which was 403m in 12:04. Highish tide going out. Calm. Water temperature 8 degC. A good swim 🏊😊 #openwaterswimming #kayaking #greenock #rwsabc (at The Royal West of Scotland Boat Club)

Thoughts on Prague

We just came back from a break in Prague. We had a good time by walking around a lot, eating & drinking and being with each other. Given my interest in dome cities what would I take away from the visit to guide me about my dome city design. This is a list of things go liked about Prague and I would hope that these things would be available (if required) in a dome city. 1 - Great walk ability 2 - green space easily accessible from the city centre 3 - affordability 4 - friendly and honest people 5 - good public transport 6 - a lively centre in the evenings with plenty of entertainment, bars and places to eat I will discuss these things more in future blogs.

Tonight was the first night of Open Water Swimming at RWSABC. A beautiful evening with sun, clear sky and no wind. We swam in the direction of the Battery Park. The tide was coming in so it was a hard swim out (35 min) but fast (15 min) coming back.😊
