What is congestion charging? Congestion charging or pricing is the practice of setting up cordon tolls around the city on a large-scale to charge entrants for entering during peak hours. Ideally, this is done in an automatic fashion with cameras registering your license plate and directly billing you. This is different from low emissions zones, [...]

Few tourists travel explicitly to see a city’s or country’s mode of transportation, but I dare say that besides transport nerds such as myself, there are examples which qualify as must-see, including Japan’s Shinkansen high-speed train, Lisbon’s old tram system, and the streetcars of New Orleans, among others. While Paris is most recently known for [...]

Fuel/Cost Savings of Improving Fuel Economy from 12->15 mpg = 30->60 mpg

Fuel economy is not as straight-forward as you might think. Image courtesy: fragallo

Consumer tip-of-the-day: increasing efficiency of fuel economy on a miles-per-gallon scale is not linear, as more miles-per-gallon (mpg) are initially better for your wallet and the planet than you might expect, and eventually trail off with diminishing returns. Last week, a friend pointed out a good blog post by Nicholas Chase and the Energy Information [...]

I am one of those people who always thought Barcelona would be my favorite city in the world. I visited several times, and though the weather, design, and food leave you wanting little else, there was always something about the sheer number of tourists (besides myself) and traffic that put me off the whole experience.

… there would be a lot of other environmental issues to deal with. This is no big revelation, but it’s a question I’ve been pondering recently: What is the state of the world, not counting climate change? Or rather, what if we managed to reduce CO2 emissions to necessary levels, what would our focus be on [...]

Like most people, I am a sucker for a good map. To indulge in this nerdity, I am launching an occasional Map Monday series, beginning with one by Simran Khosla of GlobalPost who used the CIA Factbook to put together an excellent map detailing every country’s highest-valued export. Everyone will draw a different conclusion from [...]

In the last post I presented results from my poll on the importance of cars to your everyday life. The results suggest, simply put, that its importance is sliding downwards. Yet, are we seeing this outside the US and elsewhere in similar countries? And if so, is it not just because of the global economic [...]

Thank you for your input as no less than 100 readers were kind enough to participate in my not-so-scientific survey of what is least important to them, when given a choice to give up one item ranging between a TV, vehicle, laptop/tablet, and a smartphone. I know my Social Science Surveys professor from grad school [...]

Full Frontal Nerdity

Tali_EV_London-200x200

I was once caught staring at energy efficiency guru Amory Lovins’ pocket protector, and without blinking he said, “Yes, it’s full frontal nerdity.” There was something refreshing about that sentiment, so let me similarly make my intentions clear: in joining SciAm Blogs, I hope to bring you some unnoticed news and engage you on a [...]
