Bullitt in the Wind

Human Battery - Bullitt with Wind Mill and Solar Panels

Got a call from Larry vs Harry the other day. One of their customers had converted a Bullitt cargo bike into a power station with a wind turbine and solar panels charging a battery.

That's something I had to see for myself so I called Ulrik Bing from HumanBattery.dk and met up with him and his colleagues last week.

The bicycle and the wind, in Copenhagen anyway, are often at odds with each other. It's a frightfully windy city and it always seems like there is a headwind. The very idea of combining the two is fantastic.

Creating a Bullitt with a wind turbine and solar panels is just one of many ideas on the go with Ulrik Bing, Carsten Koch [the construtor] and Claus Nørregaard. With the UN Climate Conference on the horizon in December 2009 they have a thick idea catalogue with ways to bring climate consciousness to the people.

Speaking with them and hearing their enthusiasm as they rattle off their many idealist ideas is infectious. The Bullitt cargo bike is a flagship for their projects.

One thing they mentioned was converting all the stationary bikes and spinning bikes in a fitness centre to power a certain selection of the electronics in the centre. They could run the lights, the tv, etc. and contribute to bringing down the electricity bill. All that human-powered energy can be exploited.

Thinking bigger, a company could have their employees ride bicycles with batteries. Riding to work would generate energy saved up in a battery. Upon arriving at work the bikes would be plugged into a grid that could power, just for example, all the lights in the foyer.

Another project on the drawing board is a canal boat - there are many in Copenhagen used for tourist tours - and converting it to accomodate a solar panel roof and wind turbines. The idea is that it could sail around the harbour and act as a music venue. Docking at a quay for an audience on the shore. The ticket price would be human powered contribution to the energy needed to run the concert. Guests could ride stationary bikes on shore, hooked up to the ship, and ride for a period of time. You ride, you get to see the concert.

Ulrik spoke often of 'doing something in order to get something'. It's a kind of a mantra. We need to get people actively involved in energy creation. In the flurry of ideas there was one about how kids would have to pedal - either on their own battery-equipped bike or one at home - in order to see tv or play computer games.

Carsten [at left] takes the ideas and makes them happen.

There are other bikes in their arsenal. One of them is connected to a light bulb and you can ride to see how much effort it takes to keep the light lit. Then they switch the light to an energy-saving bulb. The effort required to light it is much lower.

These kinds of tools are great for schools and the general public. They really hammer home how much energy we use and take for granted. Schools could take part in competitions with other schools to see who can generate the most energy with pedal power. Companies could do the same. The number of applications is infinite.

I wonder what the 500,000 bicycles on the streets of Copenhagen each day could generate. How much energy is produced and, if there were batteries connected to the bikes and they could be plugged in, what could we power with it?

Ulrik, Carsten and Claus are speaking with some of our major energy companies about collaborating on the many projects in 2009. We'll keep you all posted about how it's going.

7550 New Bike Parking Spots at Copenhagen Central Station

For all of Copenhagen's badassness as a bicycle city, there remains one thing that the City still completely sucks at. Bicycle parking at train stations. At Copenhagen Central Station there are only about 1000 bike parking spots. Danish State Railways can't even tell us how many spots they have. They're not sure. Even in Basel they have 800+. In Antwerp they have this . Don't even get me started on the Dutch. 12,500 bike parking spots are on the way in some place called Utrecht . Amsterdam has a multi-story bike parking facility, floating bicycle barges round the back and are planning 7000 more spots underwater . Even at the nation's busiest train station, Nørreport, the recent and fancy redesign failed miserably in providing parking that is adequate for the demand . Architects once again failing to respond to actual urban needs. It is time to remedy that. Here is my design for 7550 bike parking spots behind Copenhagen Central Station. Steve C. Montebello i...

The New Question for 21st Century Cities

It's all so simple if we want it to be. For almost a century we have been asking the same question in our cities. "How many cars can we move down a street?" It's time to change the question. If you ask "How many PEOPLE can we move down a street?", the answer becomes much more modern and visionary. And simple. Oh, and cheaper. Let alone the fact that the model at the top can move 10 times more people down a street than the model at the bottom. When I travel with my Bicycle Urbanism by Design keynote , I often step on the toes of traffic engineers all around the world. Not all of them, however. I am always approached by engineers who are grateful that someone is questioning the unchanged nature of traffic engineering and the unmerited emphasis placed on it. I find it brilliant that individual traffic engineers in six different nations have all said the same thing to me: "We're problem solvers. But we're only ever asked to solve the sam...

The Copenhagenize Desire Lines Analysis Goes to Amsterdam

Nine intersections. 19,500 cyclists. Nine hours. All in a city considered as a model for many urban planners. The Copenhagenize Design Company Desire Lines analysis tool headed south to Amsterdam to study bicycle user behaviour and how it interacts with - or is affected by - urban infrastructure. In ca lose collaboration between Copenhagenize Design Co . and The University of Amsterdam in the guise of Marco te Brömmelstroet - and for the City of Amsterdam - nine intersections in the city were filmed during the morning rush hour in order to complete the world's largest study of bicycle user behaviour. We're pleased to reveal the results of our study and showcase some of the data, analyses and desire line maps. The bicycle infrastructure in the City of Amsterdam is rather different from the typology used in Copenhagen ,where we did the first anthropological studies of the cyclists - The Choregraphy of an Urban Intersection, and others. It was t...
