My co-author Jae-ho Pyeon and I are putting the finishing touches on a draft manuscript that we've been working on titled "Analyzing the Potential of Hybrid and Electric Off-Road Equipment in Reducing Carbon Emissions from Construction Industries." This manuscript is the result of a project sponsored by the US Department of Transportation. (The DOT builds and funds a lot of highway construction, and apparently this explains their interest in this topic.)
In the course of carrying out this research I've learned a lot about construction equipment and this has at times made me feel like a kid playing in the sandbox again. In addition this project has raised as many questions for me about urban air pollution as we have answered, and I plan to keep studying construction topics. In this post, I am sharing some observations, questions and photos from walks I've taken around construction sites in San Francisco. Next month, I will post the draft manuscript.
