Researchers Turn Old Junk Drawer Smartphones Into a Mini Cloud Computing Platform


E-waste is a pretty serious problem, and researchers have been studying how to reduce, reuse and recycle old tech as long as there has been old tech to recycle. Google Research and UC San Diego came up with a pretty cool way to deal with at least some of it. 

Researchers used 2,000 discarded Google Pixel phones to create a mini computing platform. Unlike the famous Taiwanese grandfather who played Pokemon Go on 64 phones, the old Pixels underwent extensive modifications before being placed in their new home. The motherboards were removed and placed in self-governing clusters comprising 25 to 50 devices, according to the study.

The motherboards had their Android operating systems removed and replaced with Linux, which removed many consumer-facing protections, such as a low-memory killer function that helps phones run more smoothly, but would be counterintuitive in a server context. Everything that was unnecessary, like displays, camera arrays and batteries, was removed, leaving just the motherboards to do their thing.

The Pixel phone server (the blue bars) did surprisingly well on benchmarks compared with an Asus server rack.

This setup was pretty successful. According to Google, the Pixels performed better or at least on par most of the time with professional server racks like the Asus RS720A, a popular choice for enterprise data centers. This made them viable for UC San Diego’s needs, which included a small-scale cloud computing platform that could run applications for classes. 

UC San Diego says that 20 Pixels were enough to support a class with over 75 students, and with 2,000 Pixels, they could support 100 classes at once.

The big win for UC San Diego was cost. The price of the Pixel phones and the time it took to set them up was “a fraction of the usual cost” of a comparable amount of server computing power. UC San Diego intends to study how long consumer-grade electronics can last in a more intense server environment and plans to launch the system in the fall 2026 semester. 

A small solution to a big problem

While it was small-scale, this experiment has legs when it comes to further use in academia. Google says that the vast majority of school usage, including teaching, grading and even research, is “within the capabilities of a single smartphone to host.” Should UC San Diego’s experiment prove successful, colleges all over the world could use old, discarded smartphones in similar server setups to help reduce costs.

However, this approach isn’t the next big thing in data center or server construction. Data centers can process hundreds of gigabytes per second on the low end. Data centers for AI and other enterprise applications require much larger, stronger and more robust solutions, which bring with them an entirely different set of environmental concerns, like the ridiculous amount of water they need to stay cool and the fact that some data centers use enough electricity to power tens of thousands of homes.

There is no chance that a gaggle of old smartphone motherboards is going to make an impact on the greater data center industry, but it is nice to see that it does work on smaller scales, where businesses and researchers alike often overpay for cloud computing power when they really don’t need that much. 

A drop in the bucket for e-waste

It’s commendable that researchers and companies are seeking ways to use e-waste, but they still have a long way to go. The 2,000-smartphone server farm built by UCSD removed a tiny fraction of the estimated 62 million tons of e-waste entering the garbage stream every year, only 22.3% of which is properly recycled. CNET readers do better than average, recycling old tech 39% of the time, but that’s still a concern. 

An estimated 5.3 billion mobile phones are thrown away every year. That means UCSD would need to make another 2.65 million such server farms per year in perpetuity to clean it all up. There’s no expectation for one university to do so, but it shows just how big the e-waste problem really is. Those numbers also don’t take into account the large number of adults who keep old tech sitting in a closet, collecting dust. 

Other initiatives are helping with this. Right-to-repair laws in the US are slowly making it easier and more affordable to repair tech instead of just throwing it away. Governments and companies are working to raise awareness of proper e-waste recycling so that those metals and chemicals can be reused rather than left to rot in a dump somewhere. 

Should UC San Diego’s experiment prove successful, it may be another in a long line of small initiatives to help clean up a problem that was considered out of control many years ago.

Alaskan cruising is big business, with nearly two million travelers boarding mega ships each year. These floating cities move through Southeast Alaska’s port towns ofJuneau, Sitka, and Ketchikan with long transits to and from Vancouver or Seattle. They must be doing something right. But the real question is: right for whom? Discover why UnCruise offers a more immersive Alaska experience—fewer crowds, closer wildlife encounters, guided adventures, and all-inclusive small-ship travel in Glacier Bay.

We recently sailed on UnCruise’s Wild, Woolly, and Wow with Glacier Bay itinerary and experienced Alaska at a human scale, up close, unscripted, and deeply immersive. What we found was a style of travel that felt less like a vacation and more like a shared expedition. Here’s why we chose UnCruise for Alaska and why we’d do it again without hesitation.

An All-Inclusive Model That Actually Includes You

Traditional cruising relies on a dual-revenue model: low-margin fares offset by high-margin onboard spending like drink packages, shops, specialty dining, and excursions. To make the math work, those ships need 3,000 to 6,000+ passengers and rigid itineraries built around ports and schedules.

UnCruise turns that model on its head. With fewer than 90 guests and truly all-inclusive pricing, the experience feels more like an adult summer camp than a floating resort. Their ships anchor in remote bays instead of lining up at docks, and exploration is led by an in-house team of naturalists and guides, not outsourced excursion operators.

You’re invited, not herded, to experience Alaska on its own terms. For us, that meant forming real connections with the crew, with fellow travelers, and with the place itself. We learned names quickly, swapped stories easily, and capped each day with shared meals and drinks that reflected the region we were sailing through.

When Alaska Is Your Window View

Our first morning in Juneau felt surreal. The harbor was wrapped in fog as we walked along an empty dock, with tens of thousands of cruise passengers still waiting behind raised gangways. As the mist lifted, the walkways dropped, and the quiet was instantly replaced by crowds racing toward shops and excursion buses.

I couldn’t help but wonder if anyone glanced out their cabin window and felt a flicker of FOMO. If only they knew what mornings on UnCruise looked like. Day after day, our views were of waterfalls spilling into secluded bays and glaciers calving in the stillness of early morning, no crowds, no commentary, just Alaska doing its thing.

Closer to the Heart (and the Ice)

Growing up, Geddy Lee’s voice urging us to be “closer to the heart” felt like a creative manifesto. Forging our creativity, molding a new reality, and sowing a new mentality… Closer was better. Closer was where new ideas formed and deeper connections took hold. That philosophy plays out beautifully on UnCruise.

In Glacier Bay, we had an unobstructed view of Johns Hopkins Glacier, while a mega ship lingered somewhere farther out in the fog, barely visible. We could hear sea lions barking as we passed and orcas exhaling as they surfed our bow wake.

And when “close” still wasn’t close enough, we boarded skiffs. Close enough to feel the surge from calving ice at LeConte Glacier. Close enough to taste ice that had traveled decades from mountaintop to sea. Close enough to hear bears splashing as they fished below Pavlof Falls. As Rush put it, “There’s something here as strong as life.” We felt it.

Days Built Around Doing, Not Watching

A typical UnCruise day included both a morning and afternoon adventure: skiff tours, kayaking, or bushwhacking through rainforest. Each option took us deeper than the ship alone ever could, with kayaking bringing us closer still.

Trading engines for paddles let us hear waterfalls crash into Waterfall Cove and study freshly calved blue ice glittering in the morning light. Bald eagles watched from high pine perches while harbor seals lounged on stray ice floes, eyeing us just as carefully as we watched them.

Where Boots Matter More Than Deck Chairs

Some experiences require boots on the ground, and this is where UnCruise truly excels. They don’t just provide sturdy rubber boots for muddy landings, they bring the expertise to use them well.

Their skiffs deliver you to remote shorelines and return at just the right moment. On land, you’re guided by wilderness professionals with advanced medical training, GPS navigation, and safety protocols (and gear) for everything from bears to sudden weather shifts.

That preparation opened the door to unforgettable moments: wandering through old-growth forests spared by their isolation, snacking on wild blueberries still wet with morning dew, scrambling up rocky outcrops for sweeping views, and sinking ankle-deep into muskeg bogs. It felt unapologetically, unmistakably like wild Alaska.

Eating as Part of the Journey

Twice-daily adventures worked up serious appetites, and the UnCruise culinary team rose to the challenge. Meals weren’t just filling, they were thoughtfully designed to reflect the region we were exploring.

Our onboard chef, Rachel, originally from the Northeast, described Alaska as New England elevated. She leaned into the freshness of local seafood, serving dishes like butter-poached, fresh-caught halibut. And of course, there was the crab feast featuring sweet, delicate Dungeness crab with tender, flaky meat that exceeded even our lofty Alaskan expectations.

Evenings That Deepen the Day

After full days of movement and fresh air, evenings onboard were about understanding what we’d seen. Instead of shows or casinos, UnCruise offers Arctic education that builds context and meaning.

On bear-watching days, we learned how salmon runs support the entire forest ecosystem, right down to the trees. Entering Glacier Bay, we explored how microscopic life on ice underpins one of the planet’s most complex ecosystems. It was the perfect complement to what we’d experienced firsthand.

UnCruise is headquartered in Juneau, and founder Captain Dan Blanchard was adopted into the Tlingit tribe in 2013—a reflection of his deep, long-standing connection to Alaska. For more than 30 years, the company has focused on immersive, active travel with a strong commitment to environmental stewardship.

The “Un” in UnCruise is intentional: unplugging, unhurried, and undeniably different from traditional cruising. For us, choosing this road, or route, less traveled made all the difference. We may never be as truly Alaskan as Captain Dan, but that week in the wilderness left a connection that time won’t erase.
