Hasta La Gadget!

Over the past two years, the United States has seen a return to American manufacturing by some of the biggest names in tech. In 2012, Google introduced the ultimately failed Nexus Q, while Apple’s Tim Cook teased an American-made Mac. One year later, Lenovo cut the ribbon on a new plant in North Carolina; Motorola announced plans for a Made in the USA flagship; and Apple made good on Cook’s promise with its latest Mac Pro. However, even with President Barack Obama backing a return to American production and moves from big players like Apple and Google, the fear of skilled labor shortages persists. In the lead-up to July 4th, we’ll bring you four stories in four days that explore what innovation in the United States looks like today and what that means for you.

In our first installment, Jason Hidalgo sits down with theoretical physicist Michio Kaku to talk about the dangers of a Silicon Valley brain drain and building the Death Star. On day two, Darren Murph takes a tour of Babcock Ranch, the once-hopeful site of “America’s most sustainable city.” On day three, we’ll bring you Jamie Rigg’s look at tech’s reshoring efforts. And on the Fourth, Brian Heater will explore how one non-profit harnessed the power of big names like Bill Gates and Jack Dorsey to help bring coding to classrooms nationwide.

For more from the field and the factory floor, keep it locked here as we explore what it means to be Made in the USA.

You don’t have to know Shel Silverstein to know that trees are exceptionally giving. They’re responsible for our homes, paper, air, furniture and, now, energy — the “clean” kind, that is. Researchers from the Georgia Institute of Technology and Purdue University have jointly devised a patent-pending method to build organic solar cells using plant-derived substrates. Known as cellulose nanocrystal substrates (or CNC), these solar cells benefit from being truly disposable, eliminating the waste that results from the use of alternative materials like petroleum or glass. The CNC-made cells are not only transparent enough to allow light to pass into an embedded semiconductor, but they also dissolve when submerged into water, thus earning the esteemed recyclable distinction.

Although this is undoubtedly a breakthrough for clean energy tech, it’s by no means a near-future reality. Apparently, current cells can only yield a 2.7-percent conversion efficiency rate, which falls far below the 10-percent threshold met by rival fabrication methods (i.e., petroleum and glass). So, there’s still significant work to be done before the team can improve production and achieve parity with those less “recyclable” options. Until that time, consider this a comforting reassurance that a clean fuel era is well within reach.

Generating solar power from the infrared spectrum, or even nearby frequencies, has proven difficult in spite of a quarter of the Sun’s energy passing through those wavelengths. The Fraunhofer Institute for Telecommunications may have jumped that hurdle to efficiency through sulfur — one of the very materials that solar energy often helps eliminate. By irradiating ordinary silicon through femtosecond-level laser pulses within a sulfuric atmosphere, the technique melds sulfur with silicon and makes it easier for infrared light electrons to build into the frenzy needed for conducting electricity. The black-tinted silicon that results from the process is still in the early stages and needs improvements to automation and refinement to become a real product, but there’s every intention of making that happen: Fraunhofer plans a spinoff to market finished laser systems for solar cell builders who want their own black silicon. If all goes well, the darker shade of solar panels could lead to a brighter future for clean energy.

Drive west on US Route 50 through a stretch of Nevada highway known as “The Loneliest Road in America” and you’ll eventually find yourself in the rural county of Churchill. Once a solitary leg in the Pony Express route, irrigation transformed swaths of Churchill’s high desert areas into thriving agricultural communities more than a century ago. Fast forward to today and Churchill finds itself playing host to yet another interesting dichotomy — a first-of-its-kind power plant that generates electricity by harvesting renewable resources from both earth and sky.
