Why am I stuck in traffic ?

May 27th, 2009

I recently received an email from Peter Green the owner of the website www.frixo.com pointing out his website to me as it might be useful to some of the users. Given that most of my readers live in the UK I thought it would be a good idea.

While I suspect that there are many other websites reporting traffic incidents, the key concept to take away here is that communication is important. If people know what is happening on the roads they are likely to take routes that would make them go faster. This would help reduce the pressures on the road network and decrease the effects of bottlenecks. Knowledge is power and there could be a lot of money and time saved by simply knowing whether the queue you are stuck in is becuase someone had a burst tyre and is likely to get off the road soon, or because there was a major accident and you are better off abandoning your vehicle and walking home.

Even if you fail to find a route to evade whatever is causing the traffic problems, you might be able to make a phonecall to avoid other negative effects of not arriving on time. You should be able to do all that while sitting in your car, since most phones and service providers allow you to access the internet at low cost now. It is quite difficult to put a monetary value on the cost effectiveness of such information systems, especially when intangible things are involved. How much would you value avoiding the strain on your relationship that could have been caused by arriving late to your romantic dinner?

The end result is that people’s lives are made easier. So the next time you are using the roads, check the traffic reports first before you get yourself stuck without any clue why this is happening to you.

Racing Green Endurance and the Zero Race

May 26th, 2009

Going around the world is nothing new, people have been doing it in every way and every direction. Sailing, flying, and driving are just a few ways to see the globe. Some are obsessed with going as fast as they can so that their name can be put in some book somewhere where no one would ever read or care about them. There are others however who do it for the journey and some to prove a point.

Lois Palmer is apparently the first person to drive around the world in a solar car. He gave a presentation at Imperial College London (click here) where he described his feat and told everyone about zero race (click here). Zero race is well you guessed it, a race, and yes a race of electric cars (not solar, that was the twist) around the world. The electricity that the cars use will be renewable so that it can fit into the whole green theme fashion. The point here being made is that electric cars are ready so let’s move to them and cut the whole debate nonsense.

Enter Racing Green Endurance (this time click here), part of the imperial racing green project, except that they are not really about racing but more about endurance. Endurance should come in handy if they want to stay alive in the race around the world. Of course that is if they manage to find enough sponsors. So if you are cash-rich and you actually care about this kind of stuff, you should contact them. I don’t think they would say no to some money at the moment. So if enough teams manage to find the cash, the zero race should be going ahead and it will be interesting to see whether it gets any attention at all.

Green Roofs

May 17th, 2009

Who said that cities have to be dull, grey and boring? And no I am not implying we should paint all the buildings in bright yellow and pink, but we can make our rooftops green. I read an article about this in National Geographic and I think the idea seems feasible and useful.

A large surface area of a city is normally covered by buildings. Thos buildings we tend to think about them as structures that replace whatever else was there on this land. We remove forests, grassland and agricultural land in order to put a building instead. But what happens if those buildings mushroomed out of the ground instead? They just popped up from the depths of the earth. What you would expect is to find that piece of grassland still on the roof. And that is what we should aim to recreate.

Go to the roof of your buiding and plant some green, you could be planting your own vegtables as well, not just grass and flowers and helping reduce the amounts of land being converted from their natural state to agricultural land. Add to that the benefit of having a garden in every building and you will suddenly find trouble in giving this some monetary value when you are decining whether it’s worth it or not.

One of the problems facing green roofs is rain. While rain is free water for the plants, the soil can get pretty heavy as it soaks up the water. So you don’t want your roof falling down, especially when it is raining. Green roofs have come a long way and now they tend to use a number of layers in order avoid this problem. Instead of using traditional soil, soil composites are used. There are also storage and drainage layers so that in dry seasons the water is stored for the plants and when the water is in excess it just overflows the storage and drains away.

So now that green roofs are becoming more and more feasible, we should expect more people to adopt them. Probably start with institutions and evetually spread to homes. So what are you waiting for? Start looking into how you can make your roof green today.

Vélib’

May 17th, 2009

So it’s been some time, you wait for a couple of months and then they all come together, from one reason to another I haven’t been posting anything for a long time now. But it seems like the rain is gone and the sky is blue, and it’s time to write again.

So I had some nice trips over the holidays including Paris. While most people like to see the museums and walk along the river, enjoy the art galleries etc.. I don’t. Touristy stuff is for tourist and as clihe as it sounds, I don’t like to be a tourist. When I visit a city, I want to understand it, I want to know what it’s like to live there, which supermarkets do you go to? Which areas are known for what? what underground passes are on offer? How fast are the internet speed connections available? How are the relationships between parisiens? How do you treat a stranger? How do you treat a friend? Where are the social boundaries? What values does this city uphold? Now, I have noticed that it seems like I am turning this blog post into talking about me, so I’ll cut it short and start talking about Paris. Actually a very small aspect of Paris, its bicycles.

At first sight, you might think that loads of people in Paris have the same type of bicycle, it’s not particularly beautiful and it doesn’t look cheap either. And then you find a large number parked next to each other by the sidewalk. No it’s not a showroom, it is a velib station. You pay a deposit, get a subscription, get a card, use it to unlock the bicycle and then drop it off at any other station. A cheap rate per hour and that’s all. Simple.

Velib Station in Paris

Sounds pretty good, everyone has easy access to a bicycle, no need to buy one, no need to find a place to store it, no need to worry about it being stolen, and best of all if you ride a bike to work and it rains, just take public transport back without worrying about bringing your cycle with you on the bus.

So less emissions, less traffic and more excercise. Why is this not spreading to other cities I don’t know.
