As always, Mechanical Engineering is a member benefit for ASME members, so the content is gated.

Lots of thanks to Sam Grate of the Auburn Cord Duesenberg Museum for providing all sorts of information on the Duesenberg company.

Those brakes, and the Duesenberg story, were written up by editor in chief @jeffreywinters.bsky.social

Duesenberg Hydraulic Brakes Got America Moving - ASME
Before Duesenberg made its hydraulic braking system standard, operating a car could be a physical challenge. This ASME Engineering Landmark opened the roads to everyone.

It’s easily more than $3. Here’s our chart from a while ago and our more recent paper. For climate alone, every $100/tonne GHG adds $1/gal. Whether driving costs us all an extra $3 per gal or $6/gal, it’s not zero, which is what we pay now. www.rand.org/content/dam/... & pubs.acs.org/doi/10.1021/...
Figure 2.1 An Estimate of the Per-Mile Externalities Associated with Driving an Automobile Oil imports (0.8¢) Air pollution (1.9 ¢) Accidents (2.4¢) Climate change (2.3¢) Congestion (5.6¢) Noise (0.1¢) NOTE: Estimates are in 2010$ and based on NHTSA (2012a) values. GHG emissions use the central value from the U.S. Interagency Working Group on the Social Cost of Carbon (2013). Emissions factors are well-to-wheel for a 24.8-mpg vehicle using data from Argonne National Laboratory (2012). RAND RR443-2.1 -RULE EL oclence & lecmoroou 2. External Costs of Vehicle Travel <Q= Jump Tov There is a rich literature discussing personal vehicle travel externalities. The U.S. government uses monetized external cost damages in regulatory impact assessments and policy decision-making about fuel economy standards. (11) Studies generally use these and other monetized external cost damages to estimate the social costs of travel, estimating values from congestion, crashes, air pollutant and GHG emissions, and noise totaling 2.6-36.1 cents per passenger-km traveled, on average (12) (in 2019 USD). We make a contribution to the literature by conducting a systematic estimation of the external costs of shifting to TNC travel. For traffic externalities, including congestion, crashes, and noise, we conducted an extensive literature review (described in detail in the Supporting Information) and identified the most relevant estimates and ranges of marginal externalities for our U.S. urban TNC scope: 4.1-7.1 § per km for congestion, (6,50-52) 0.8-6.6 ¢ per km for crashes (6,12,53,54); and 0-1.9 ¢ per km for noise. (55) From the literature on the social cost of carbon, we adopt a range of $15 to $149 per metric ton of COz equivalent. We use these ranges to specify distributions for the Monte Carlo analysis.

We've been digging into deep geothermal for a few years now, including the cover story for our December issue, which looked at some of the companies leading the charge into this energy frontier.

Deep Geothermal is the New Energy Frontier - ASME
A new generation of startups is developing the drilling technology needed to reach rocks hot enough to provide clean, sustainable power whenever we need it.
