The Greening of Google

Corporate rooftops are the latest frontier in solar energy generation

11 min read

It's another brilliant day at the world headquarters of the hottest company on the planet. Some shirtless employees are playing a lunchtime game of volleyball while others stride across campus with laptops tucked under their arms. The place fairly crackles with energy, and in more ways than one.

Up here on a roof at Google's leafy and sprawling Mountain View, Calif., campus, with the shouts of the volleyball game just barely audible, sunlight glints off 9212 polysilicon solar panels stretching out toward the horizon. Amid the irregular jumble of angular roofs, a single south-facing wave stands out, a pitch and roll frozen in place against a backdrop of foothills.

This Idea Wasn't All Wet: The Sensing Water-Saving Shower Head Debuts

An engineer’s dinner-table invention is finally a consumer product

For Evan Schneider, the family dinner table is a good place for invention. “I’m always, ‘Wouldn’t it be cool if this or that,’” he says, “and people would humor me.”

In 2012, with California in the midst of a severe drought, Schneider, then a mechanical engineering graduate student at Stanford University, once again tossed out a “cool idea.” He imagined a shower head that would sense when the person showering moved out from under the stream of water. The shower head would then automatically turn the water off, turning it back on again when the person moved back into range. With such a device, he thought, people could enjoy a long shower without wasting water.

Can AI’s Recommendations Be Less Insidious?

Artificial intelligence has us where it wants us

Many of the things we watch, read, and buy enter our awareness through recommender systems on sites including YouTube, Twitter, and Amazon. Algorithms personalize their suggestions, aiming for ad views or clicks or buys. Sometime their offerings frustrate us; it seems like they don’t know us at all—or know us too well, predicting what will get us to waste time or go down rabbit holes of anxiety and misinformation. But a more insidious dynamic may also be at play. Recommender systems might not only tailor to our most regrettable preferences, but actually shape what we like, making preferences even more regrettable. New research suggests a way to measure—and reduce—such manipulation.

Exploring the Value of Power Modules

Learn how power modules can reduce power supply size, EMI, design time, and solution cost

Texas Instruments

In this training series, we will discuss the high level of integration of DC/DC power modules and the significant implications that this has on power supply design.

Watch this free webinar now!

In addition to high power density and small solution size, modules can also simplify EMI mitigation and reduce power supply design time. And thanks to improved process and packaging technology, a power module may even provide all of these benefits with a lower overall solution cost as well.
