Solar Energy From a Road Surface is Now a Reality

Roads are great for allowing us to get from here to there in a quick and safe way. But while they're waiting to serve the next vehicle, they're just lying around idle, making the world warmer with their dark surfaces.

But it doesn't have to be that way. A city in the Netherlands just installed the first bit of road capable of generating electricity: this bike path - of course it's a bike path! - has solar panels embedded in the surface, beneath a protective glass layer.

Limits on car sales in Singapore: a model for capping carbon emissions?

Singaporean authorities would rather that you not buy a car at all. After all, the tiny city state has excellent state-of-the-art public transport, and not a lot of space for roads and parking. But its wealthy population loves cars; even steeply increasing road taxes didn't keep the automotive overpopulation from becoming an acute problem. By the 1980s Singapore's road congestion had become unbearable.

Enter the Certificate of Entitlement.

The COE scheme is birth control for cars - to be precise, import control: Every year somebody counts the number of cars that have been retired from Singapore's automotive fleet, either by being scrapped or by being sold abroad. Also, the desired number of cars is determined for the next year. Those two things set the number of new cars that can be sold for that year, embodied by Certificates of Entitlement.


A Certificate of Entitlement is the right to own a car in Singapore for ten years. The COEs go on an auction, so the price is determined by how badly people want to own a car. This month, a COE in the "small car" category (engines up to 1.6L and 130HP) went for S$ 63,880.

My Dutch Canondale

I was getting too old for my bike.

Not that I'm getting too old for biking. Let me explain.

My trusty bike is a Canondale that has been with me for twentyfive years now, and on which I spent happy days with my friends, tearing up the trails in the woods.

The bike easily accommodated my children when they came: first in a baby seat that I hung from the handlebars, then in a child seat on the back. I have two Dutch bikebags that I hang from the luggage rack, for errands to the library, the grocery store, etc.. The only thing you have to be careful about is that the Canondale, with its aluminum frame, is considerably lighter than a standard Dutch bike, so you have to be more careful balancing cargo - such as a baby at the handlebars.

About those handlebars. You know how mountain bikes have straight handlebars? It gives you better handling on rough terrain.

But I'm never on rough terrain any more. And the straight handlebar, not exactly ergonomic, was starting to hurt my wrists. Leaning on them while biking doesn't help that at all. Also, as I'm getting older I find that I'm less comfortable leaning over: I feel much better balanced on a Dutch bike that allows you to sit up straight.

I considered importing a Dutch bike. CelloDad told me I was crazy. And he has a point. A good Dutch bike of old-fashioned quality is not a cheap item, and then you have to get it over here somehow.

But I did the next best thing: bought myself a Dutch handlebar this summer. Dutch bike shops have a selection of them, with varying widths and different curvature. A handlebar is much cheaper than a whole Gazelle bike, and you can carry it inside a suitcase. Last week, I finally made it to a local bike shop, the haunts of one of my rideshare children; they did an expert job of installing the handlebar.

Greener Ways to Get There

I've written before of the lowest-carbon way to get from here to there, and summarised it in this graphic:

The people at 1BOG (which stands for One Block Off the Grid) have made a much larger infographic which is more complete and breaks things down by the distance traveled. I don't usually like large infographics, but this one is worthwhile because it shows that for transportation, not one size fits all.

A few takeaway points:

For travel inside or near town, nothing beats a bike. (And it makes you feel happy. And it's good for you!).

People's Climate March: of Community, Communication, and Things Which Must Not Be Named.

I've a confession to make: this is my very first march, ever. But even I could tell that this was going to be special, when I showed up at the train station at an ungodly hour, and the woman who got her ticket before me turned around, glanced at the sign that CelloPlayer had made, and said cheerfully, "Looks like we're headed for the same place", before disappearing to the platform.

When I had made my way onto the same platform, I could see her sitting a bit further down. But I never got a chance to say hi to her because a gentleman came up to me and said something about my sign. I looked up, into kindly eyes framed by white hair - and a rainbow beard.

Heaven help me, I stared. Like a five-year-old.

People's Climate March: so big, there was no end to it.

As my CelloPlayer was working on the sign that I was going to carry at the Climate March, we talked about how many people were expected to walk the March.

Being a geek, and never one to pass up a teaching moment, I pulled up a map of Central Park West where marchers were to collect. We set out to answer the question: if the organisers are expecting 100,000 people to show up for the march, would they fit in the space provided for the lineup?

Climate March: I'm Marching for my Mom

Of course, I'm marching for my children. Actually, I'm marching for all our children. And this is where my mom comes in.

For a number of years, my mom worked as a pediatrician in a tropical country. She worked with a doctor who ran his practice more like a charity clinic, and at public hospitals. She never had a private practice, which would have been the more lucrative option. But that's not why she became a doctor.

For a time, she lived in a tiny village where the village women would sometimes bring their sick children to her veranda: my mom always helped their children, without asking for payment. The next day those moms would be back to thank her, bringing half a dozen eggs, or a basket of vegetables: whatever they could spare. And a child on the mend.

How will you travel to the Climate March?

So, Bill McKibben of 350.org has extended an open invitation for everyone to come to New York and march. The People's Climate March is intended to push world leaders convening at the climate summit two days later on 23 September, to get into gear and start doing something meaningful about our collective carbon emissions.

Here's a vexing question that comes up around the Climate March: aren't marchers expending large amounts of carbon emissions to get to New York?

VW Golf TDI: 52 mpg

Road trip, mostly highway, for the beginning of the school year. That tank really could hold enough for 600 miles. My brave diesel Golf did 52mpg on the highway. Not a hybrid!

I just needed to brag record that.

Enough People

Following the post-war baby boom, and a burgeoning prosperity in the West, the 1960s were awash in cars as well as enterprising young people. It was almost inevitable that the practice of phone booth stuffing (remember phone booths?) gave way to car stuffing.

Fun, right?

At the time, the favourite car to stuff with people was the VW Beetle. And the Morris Mini. Around the same time, concern about world population - or rather, over-population - began to surface among the general public. Maybe being immobilised over the steering wheel by the bodies of friends made people think.

Eight Ways to Catch the Train - None by Driving Your Car

Rail is wonderful. Rail is great. Rail is low-carbon, low stress and often low-cost as well. But too often, the lack of a good way to get to and from the railway station can be a dealbreaker. So here are a few ways to get access to the station, as modeled in Delft, a Dutch city of about 100,000.

1. BYO bike
On your home turf, your own bike is the method of choice. Bicycle parking, or "fietsenstalling" in Dutch, is free on the outside racks. There is a small daily fee for a spot on the covered racks where your bike stays dry and an attendant keeps an eye on things. (The building's colour, "Delft Blue", was probably chosen for the benefit of visitors).


Most stations in Dutch cities offer bicycle parking, ranging from a few racks in small towns, to the three-story bicycle palace next to Central Station in Amsterdam. Which is pretty full on most work days.

If you must have your very own bike where you get off the train, you can bring it with you for a small fee. There are designated places where you can store your bike on the train.
