5 Big Ideas for High-Temperature Superconductors

Cars That Think

“Over the past 15 years, the emphasis has moved toward using [these materials] less as high-temperature superconductors and more as high-field superconductors,” says Venkat Selvamanickam , who directs the Applied Research Hub of the Texas Center for Superconductivity at the University of Houston.

False Starts: The Story of Vehicle-to-Grid Power

Cars That Think

They wanted to see whether an electric vehicle could feed electricity back to the grid. The company’s president, Tom Gage , dubbed the system “vehicle to grid” or V2G. And EV owners would become entrepreneurs, selling electricity back to the grid. And indeed, that’s how promoters of vehicle-to-grid technology perceive the EV.

Heating Buildings With Solar Energy Stored in Sand

Cars That Think

In a region known for long, dark winter nights, Polar Night Energy is building a system in the city of Tampere that can heat buildings with stored solar energy — all day, all night, and all winter long. This means that storing and distributing energy is as important as its generation. The apparent contradictions do not end there.

This Dutch City Is Road-Testing Vehicle-to-Grid Tech

Cars That Think

Unlike those you may have grown accustomed to seeing, many of these stations don’t just charge electric cars—they can also send power from vehicle batteries to the local utility grid for use by homes and businesses. Debates over the feasibility and value of such vehicle-to-grid technology go back decades. This is good for the grid.

Gravity Batteries, Green Hydrogen, and a Thorium Reactor for China

Cars That Think

2021 was a big year for energy-related news, what with the ongoing hunt for new forms of energy storage and cleaner if not carbon-free electricity and events and research that spotlighted the weak links in our power grid. No battery is perfect, however, so engineers keep pushing for new and improved ways to store those electrons.

NSF funds U of Kansas researcher developing machine learning technology to monitor and prevent thermal runaway in Li-ion batteries

Green Car Congress

Supported by a new five-year, $500,000- grant from the National Science Foundation, a researcher from the University of Kansas is developing machine learning technology to monitor and prevent overheating in lithium-ion batteries. The problem is more pressing for large systems as they face higher vulnerabilities.
