Michalek quoted in Marketplace article about electric vehicles
Marketplace

EPP/MechE’s Jeremy Michalek was quoted in a recent article on Marketplace on Electric Vehicles (EVs). Michalek was interviewed about his experience and expertise on the sparse infrastructure for EVs. He explains that if people are going to adopt EVs en masse they have to be able to travel with them and own them even if they live in an apartment. “If you don’t have off-street parking, you need to know that you are going to have access to public chargers and be able to reliably charge your vehicle,” Michalek said.


Presto quoted on air pollution and heart disease
Fatherly

MechE’s Albert Presto was quoted in Fatherly on various air filtration systems to protect yourself from air pollution. “The better the filter, the faster it will get clogged, so it needs to get replaced more often than a filter that lets a lot of particles through,” Presto said. He explains that inside the home, a HEPA filter is the best air filtration system on the market. But it’s expensive and has to be replaced often. Presto explains that most air filters use the MERV system in which the higher the MERV number, the more efficient the device is at filtering particles out of the air, which is useful to check when buying air filters.

Whitefoot quoted on electric vehicles
Vox

EPP/MechE’s Katie Whitefoot was quoted in a Vox article for her expertise in electric vehicles in public policy. “Efficiency regulations are still really important even as automakers are making pledges to electrify their fleets,” Whitefoot said. The article describes the various hurdles in converting our U.S. car population to electric vehicles. The car industry moves slowly and no matter how fast we convert to electric vehicles it could still take decades to get gas-powered cars off the street since the average lifespan of a car is 11 years. Car companies are also less inclined to take risks as the economy falters. “Uncertainty in and of itself has a lot of impact on the industry in terms of long R&D planning,” Whitefoot explains.


Michalek quoted on school bus environmental impact
Popular Science

EPP/MechE’s Jeremy Michalek was quoted in Popular Science article about the new federal Clean School Bus Program. The program aims to replace diesel-powered school buses with electric buses over the next five years. “When diesel is burned in a bus engine, it produces fine particulate matter—particles with a diameter much smaller than human hair—that floats in the air and lodge deep in our lungs when we breathe them in,” Michalek said. He further explained the dangers of carbon pollution in an urban environment and also that electric buses are not “pollution-free” as it still pollutes the environment to produce the batteries for vehicles like these.


Yim and Johnson quoted on small robotics
IEEE Spectrum

MechE’s Aaron Johnson and Justin Yim were quoted in an IEEE Spectrum article highlighting their work in small humanoid robots. Their work was displayed at the IEEE International Conference on Robotics and Automation(ICRA). The presentation highlighted a 15-centimeter bipedal robot. “Our goal with this project is to make miniature walking robots, as small as a LEGO Minifigure (1-centimeter leg) or smaller.” said Yim. Johnson was quoted as saying, “Minimally actuated designs that leverage passive dynamics will be key. We aren't there yet on the LEGO scale, but with this paper, we wanted to understand the way this particular morphology walks before dealing with the smaller actuators and constraints.”

Whitacre interviewed on environmentally friendly batteries
Instigators of Change

Scott Institute Director Jay Whitacre was interviewed in the podcast Instigators of Change on how batteries can still have a negative impact on the environment. He explained how, depending on where you are in the world, a hybrid vehicle might be a smarter choice than fully electric vehicles (EVs). The reason for this is a combination of factors from how the electricity for the EVs is generated to the fact that battery technology has not progressed past some major hurdles in its design since the 1990s. Whitacre points out that the batteries first used in Tesla cars were nearly identical to those developed in the late ’90s.


Majidi quoted on complex robotic hand manipulation
Lifewire

Majidi quoted on gallium in bendable electronics
Smithsonian Magazine

MechE’s Carmel Majidi was quoted in Smithsonian Magazine ongallium’s use in wearable electronics. “You can use it to track your own body’s motion, or the forces that you’re in contact with, and then impart that information into whatever the virtual world is that you’re experiencing,” Majidi said. Wearable electronics is just one of many uses of gallium the article covers. Majidi discusses how the bending, crunching, and flexing of these gallium circuits “printed” onto the hand or circuit can change the current flowing through the circuit and therefore change the input to a computer tracking movement.

Whitefoot quoted on electric vehicle industry
Detroit Free Press

EPP/MechE’s Kate Whitefoot was quoted by the Detroit Free Press on competition in the electric vehicle industry. Whitefoot said the top-selling EVs in the future will depend on how the batteries perform. So the companies that design and make the best batteries, win. “If you want to come in, like a Tesla, you have to know both sides of the business: How to make a great battery and also how to build vehicles. It’s not enough to do just one of those sides,” Whitefoot said. “Those companies that can build on expertise in both manufacturing and batteries will have a competitive edge.”


Michalek quoted on electric vehicle chargers
Detroit Free Press

EPP/MechE’s Jeremy Michalek was quoted by the Detroit Free Press about GM’s plan to install electric vehicle chargers at their worksites for free use by employees. “But there are a lot of households that rent or have off-street parking, so adopting EVs for those households is a harder sell,” Michalek said. “So if you have a stable job such as at General Motors, that charger at work might make a difference in your willingness to adopt.”


Litster interviewed on on virtual cycling program

Gomez interviewed on infrastructure
Background Briefing

MechE’s Nestor Gomez was interviewed on the podcast Background Briefing on infrastructure after the bridge collapse in Pittsburgh. “A lot of these bridges will have to be replaced, and to be fair, we almost never build a bridge to last 100 years. If it does last 100 years, then we consider that a great success,” Gomez said. “But the lifespan of a bridge is maybe 50 or 60 years. [The Fern Hollow Bridge] probably had a few more years left in it, but corrosion and other kinds of damage wore it down. It was 52 years old.”

Michalek quoted on climate and travel
Grist

EPP/MechE’s Jeremy Michalek was quoted in Grist on travel and its effect on climate change. There are multiple variables that effect climate and travel, such as the age and model of one’s car, traffic, and distance. For Michalek, the difference lies is how you tackle these variables together. He said, “The more you accelerate really quickly and then come to a quick stop—that type of aggressive driving certainly consumes more energy,” also leading to more carbon emissions.
