A Ventilation Exemption Letter could be on the rise after the Shelter in Place /Social Distancing is released.
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 [...]
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 [...]
3D printing is helping in this age of COVID-19. Printing automatic door openers and PPE Equipment for our Medical Force on the Frontline.
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. I
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 [...]
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 [...]
Electric Vehicle Battery Materials Fire car Figure 1 - Electric Vehicle on Fire What Can Silicon Valley Do About EV Battery Sourcing Issues? Most electric vehicle batteries are lithium based and rely on a mix of cobalt, manganese, nickel, and graphite and other primary components, can be very dangerous, battery [...]

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 [...]
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 [...]
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 [...]
