    I recently had an twitter and email conversation with Benjamin Ross about rail vs. bus benefit/cost analysis (BCA). The problem is that conventional BCA in practice does not consider the quality differences of different modes, focusing primarily on travel time, monetary costs, and monetized externalities. Assuming everything else were analyzed correctly, this leads us to over-invest in low quality modes and under-invest in high quality modes, from a welfare-maximizing perspective. Let’s start with a few premises 1. The value of time (value of travel time savings) of each user differs…

    Airlight Energy, a Swiss-based supplier of solar power technology, has partnered with IBM Research to bring affordable solar technology to the market by 2017. The system can concentrate the sun’s radiation 2,000 times and convert 80 percent of it into useful energy to generate 12 kilowatts of electrical power and 20 kilowatts of heat on a sunny day—enough to power several average homes. Airlight Energy and the IBM Corporate Service Corps (CSC) will team up to donate a High Concentration PhotoVoltaic Thermal (HCPVT) systems to two deserving communities. Each winning community will…

    Soon enough it will be Winter. Again a landscape covered with white powdery snow will reveal where travelers want to go. The first figure is an aerial shot of the former environment around the McNamara Alumni Center on the University of Minnesota campus. The second figure is in front of (behind) McNamara . Though there is a sidewalk just on the right of this image, pedestrians prefer the straight line path between the Scholars Walk and the diagonal path across Walnut from Beacon Street to the intersection of Oak Street and Washington Avenue. And why shouldn’t they? It’s cold…

    I will be giving a Seminar in Civil and Materials Engineering  at University of Illinois at Chicago on October 3, 2014 at 11:00 AM. The Talk is in 1047 Engineering Research Facility (ERF). The Transportation Experience: From Steamboats to Streetcars. Abstract: The talk explores the historical evolution of transportation modes and technologies. It traces how systems are innovated, planned and adapted, deployed and expanded, and reach maturity, where they may either be maintained in a polished obsolesce often propped up by subsidies, be displaced by competitors, or be reorganized and renewed.

  • Minimize Air Conditioning

    What if we could rely on “natural” air conditioning to minimize energy use? Swedish architect Anders Nyquist takes us to a school in Timrå, Sweden, that keeps cool and warm by mimicking the flow of air through anthills and termite mounds. This is an example of how designing a home or building properly can create a comfortable environment using less resources. If the termite’s can figure this out, perhaps we can too.
