Helping the Medical Community – Have a 3D Printer? Medical Face Shields during the Th COVID-19 outbreak continues to expand globally. Information from healthcare organizations say that some distributors have placed certain types of personal protective equipment (PPE) on allocation, therefore, Basing the quantity of Medical Face Shields available to the healthcare organization on previous usage, not projected use. This formula greatly puts the front-line health workers at great risk. Medical Face Shields simple in design, produced and assembled by hobbyists on their own home 3D printers. Searching for a way to [...]
3D printing is helping in this age of COVID-19. Printing automatic door openers and PPE Equipment for our Medical Force on the Frontline.
Net Zero energy homes are just like any home except more appropriate in today's world. Regular grid-tied homes that are so air-tight, well insulated, and energy-efficient that they produce as much renewable energy as they consume over a year. Occupants virtually receive no energy bill and a carbon-free home. A Net Zero energy home combines advanced design and superior building systems with energy efficiency and on-site solar panels. Homes are ultra-comfortable, healthy, quiet, sustainable that is affordable.

rying to get commercial truck drivers to accept an electric vehicle over the internal combustion engine that they've known for years will be a challenge, but not an impossible one.What it's going to take is getting more concept vehicles out there, and giving more people the opportunity to ride in these vehicles.

Combining new classes of nanomembrane electrodes with flexible electronics and a deep learning algorithm could help disabled people wirelessly control an electric wheelchair, interact with a computer or operate a small robotic vehicle without donning a bulky hair-electrode cap or contending with wires.
Material Scientist Ponder What to Do With Used EV Batteries As electric vehicles become mainstream, mechanical engineers and chemical engineers are trying to address the big environmental question: what do we do with the used lithium-ion batteries? The batteries used in electric cars are physically large, last 8 to 10 years, and will account for 90 per cent of the lithium-ion battery market by 2025. This will increase lithium demand fourfold, and more than double the demand for cobalt — two of their essential elements. The price of cobalt has [...]
Degradation of EV Lithium Batteries Battery degradation in Electric Vehicles (See Figure 1. to Right) leads to capacity fade, thereby shortening the vehicle’s possible range. Patterns are beginning to emerge and provide valuable insight into EV battery capacity and lifetime. Most drivers are retaining over 90% of original capacity Range Anxiety Some cars have a range of only 106 miles, equivalent to just over three times the average daily drive in the US. New Electric Vehicles are expected to have a range of up to 235 miles, a 220% increase, therefore, range is [...]
A Licensed Mechanical Engineer at Glew Engineering Consulting was asked by a company in Southern California to provide a Professional Engineer (P.E.) review of body modifications that they made to a theme park owned 1983 Sport Utility Vehicle (SUV) that they had converted to an electric vehicle. Figure 1. A Mechanical Engineer Analyzed the Front of Custom Sport Utility Vehicle Licensed Mechanical Engineer Reviews a Modified Electric Vehicle The client had already designed and built a vehicle, so Glew Engineering analyzed an “as built” vehicle. The company [...]
Italian Masters: Leonardo da Vinci – Artist, Engineer, Scientist GalleryElectrical Engineering, Engineering Consulting, Expert Witness, Finite Element Analysis, Licensed Mechanical Engineer, Mechanical Engineering, Mechanical Engineering Consulting
Figure 1: Leonardo da Vinci, by Francesco Melzi Over the course of this blog series, I have written about a number of Italian Masters of science and engineering, from astronomers like Galileo and Cassini to physicists like Torricelli and Venturi. I’ve saved the best for last, however: Leonardo da Vinci. He is the quintessential renaissance man who fits both our running definition of “Italian Master” as well as being included in the standard list of Masters with Rafael, Donatello and Michelangelo Leonardo’s incredibly broad array of talents and interests have long been the subjects [...]
Italian Masters: Volta Jump-Starts Electrical EngineeringFigure 1: Girolamo Cardano (1501-1576) Welcome back to our series on Italian Masters of math and science. Last week I wrote about Galileo’s extensive accomplishments both in the field of astronomy and beyond. This week, I’ll take a look at another renaissance polymath who dabbled in astronomy, along with his work in mathematics, medicine, biology, chemistry, philosophy, and gambling (yes, seriously): Girolamo Cardano. Cardano is a less well-known figure than Galileo or some of the other scientists I’ve written about who have famous equations or units [...]
Figure 1: Allesandro Volta We’ve been taking a break from hard-hitting mechanical engineering and materials science blogs with some pieces on the Italian masters of science, mathematics and engineering in the 16-19th centuries. I’ve previously explored the lives and contributions of Evangelista Torricelli, Giovanni Venturi and Giovanni Cassini. For this blog, I’m focusing on Alessandro Volta, who helped revolutionize our understanding of electricity and electrochemstry it in the late 18th century. […]
Figure 1: Mars Exploration Rover By NASA/JPL/Cornell University, Maas Digital LLC [Public domain], via Wikimedia Commons Depending on which Facebook pages or Twitter feeds you follow, some of you may have caught wind that Opportunity (Mars Exploration Rover B, Figure 1) recently passed its twelfth anniversary of its landing on the red planet. Opportunity’s ongoing trek across Mars represents a fantastic accomplishment in engineering. At the time I’m writing this, the rover has been in continual operation for over 4,300 Earth days (that’s about 4,185 Sols, or [...]
