Now, Takahito Iida at the University of Osaka has proposed a new energy-harvesting technology that uses gyroscopic flywheel system that can be tuned to absorb energy efficiently over a broad range of ...

The previous column talked about the invaluable importance of electricity in modern-day society. It also talked about the phases of the Industrial Revolution si ...

When a growing share of electricity generation depends on sunlight, the ability to predict earlier and respond faster can start to matter as much as owning megawatt-hours.

A stream of compressed air does not look like a power source. In factories, it usually hisses through pipes, drives tools, then disappears as waste. But under the right conditions, that same airflow ...

RMIT University researchers have developed a flexible nylon-film device that generates electricity from compression and keeps working even after being run over by a car multiple times, opening the ...

Is Your Generator Too Loud? Here’s How You Can Measure Decibels and Reduce the Noise.

The squeaking of sneakers on a gym floor is usually attributed to friction, specifically a stick-slip variety that involves cycles of sticking and sliding between two surfaces. But that model is best ...

Ever had an idea for something that looked cool, but wouldn't work well in practice? When it comes to designing things like decor and personal accessories, generative artificial intelligence (genAI) ...

Physics is the search for and application of rules that can help us understand and predict the world around us. Central to physics are ideas such as energy, mass, particles and waves. Physics attempts ...

Over on YouTube [Andrew Neal] has a Function Generator Build for Beginners. As beginner videos go this one is fairly comprehensive. [Andrew] shows us how to build a square-wave generator on a ...
