megawatts, which improves on the facility’s original design capability. The accelerator’s higher power provides more neutrons for researchers who use the facility to study and improve a wide range of materials for more efficient solar panels, longer lasting batteries and stronger, lighter materials for transportation.

A Brief History of the World’s First Planetarium

Cars That Think

The use of models to show the movements of the planets and stars goes back centuries, starting with mechanical orreries that used clockwork mechanisms to depict our solar system. A modern upgrade was Clair Omar Musser’s desktop electric orrery , which he designed for the Seattle World’s Fair in 1962.

Generating Power on Earth From the Coldness of Deep Space

Cars That Think

As the technology improves, we see it enabling solar panels that work at night as well as day, powering remote sensors. But about a decade ago, our research group at Stanford designed a material that’s remarkably efficient at sending heat out to that reservoir of cold while preventing heating from both the sun and the environment.

So IEEE Spectrum is making one of its occasional forays into science fiction, with a short story by Karl Schroeder about the unexpected outcomes from building a computer out of planet Mercury. This strategy would also make it easier to harvest solar energy. There are materials stronger than steel, but molecular bonds have a limit.”

The Importance of Recycling and Repurposing EV Batteries

Setec Powerr

Spent lithium-ion batteries contain hazardous materials like lead, cadmium, and mercury, which, if not properly disposed of, can leach into soil and water, causing significant ecological harm. These retired batteries can effectively store energy from renewable sources like solar or wind, providing a stable power supply when needed.

A New Wildfire Watchdog

If the power source is limited in capacity, such as a battery, or in availability, such as a solar panel, the computer also monitors and manages power consumption. A hundred years ago, centimeter-scale tilt switches used a conductive blob of mercury rolling along a glass tube to close an electric circuit.
