Small Step for Batteries, Giant Leap for Electric Cars

By Jonathan Trinastic @jptrinastic Solving the Silicon Swelling Problem in Batteries The dream of an electric transportation revolution—recharging stations dotting rural highways, noiseless sedans gliding across pavement—lives in the minds of many who hope to move beyond oil dependence. But the reality of this transformation will elude us until battery technology improves. Expensive and overweight, current lithium-ion (Li-ion) battery technology cannot support long car trips and would require lower costs to be commercially viable. Now, the ignition for such a revolution may be arriving in the form of silicon. New…

Temporary Bridge for Emergency Evacuation

By Kate Stone Earthquakes, floods, tsunamis, and landslides, and other natural disasters can damage infrastructure, such as bridges. What can be done to aid the rapid evacuation of survivors and delivery of aid? Enter the Mobile Bridge® Version 4.0 (MB4.0), a new concept in temporary bridge construction. In the aftermath of a natural disaster, rapid repair of infrastructure is crucial. Expanding in just five minutes and capable of carrying automobiles, MB4.0 is being hailed as the world’s fastest, largest, strongest, and lightest expanding temporary bridge. It’s a new type of…

Solar Energy that Doesn’t Block the View

A company is making completely see-through solar energy panels for our phones and tablets. Next, for our car and home windows. By Kate Stone A team of researchers at Michigan State University has developed a new type of solar concentrator that, when placed over a window, creates solar energy while still allowing people to see through the window. It is called a “transparent luminescent solar concentrator” and it can be used on buildings, cell phones, and anything else that has a clear surface. According to Richard Lunt of MSU’s College…

New Solar Energy Storage Works at Night

By Kate S. Most solar energy systems rely on using sunlight as an immediate power source, but can’t function at night or in cloudy weather. So, what if a solar cell could store solar energy and release it for use after the sun goes down? That’s the technology a materials science and engineering team from the University of Texas at Arlington has developed. They have successfully built a new energy cell that can store large-scale solar energy, even when it’s dark. The prototype is an “all-vanadium photo-electrochemical flow cell” that…

Clean Hydrogen Production for 200 Hours

By Kate S. Scientists at Stanford University have just built a low-cost water splitter that uses a single catalyst to produce both hydrogen and oxygen gas. This is an invention that could pave the way for a boom in production of clean-burning cars. The scientists say that their device, which can run nonstop for an unprecedented period of time, could provide a renewable source of clean-burning hydrogen fuel for transportation and industry. The team used lithium-ion battery technology to create one low-cost catalyst that is capable of driving the entire…
