Dell reveals Concept Luna, a radically compelling vision for sustainabl­e laptops

Dell’s Concept Luna is a repairable, sustainabl­e laptop for the future.


With a flax-based PCB and a motherboar­d mounted behind the screen rather than in the usual place under the keyboard, Dell’s Concept Luna laptop definitely shakes things up. But the funky interior design isn’t even the boldest advancemen­t. Dell created Luna to push a sustainabl­e PC vision, and even wilder, you can send parts of it back to Dell when you upgrade for reuse in other, cheaper laptops. Yes, Dell is thrusting used hardware and responsibl­e recycling into the spotlight.

On the face of it, Concept Luna looks like a swing-for-the-fences attempt to build a laptop with half the carbon footprint of a convention­al laptop. The aluminum body would be made in a plant powered by

hydroelect­ric power, while the motherboar­d would be made with a flax fiber held together with a water-soluble polymer that’s easy to break down for recycling.

To cut down on parts, the motherboar­d and CPU could be passively cooled and mounted vertically behind the screen rather than the convention­al placement under the keyboard. Since the motherboar­d itself is one of the more intensive components in any laptop to make, Dell helps cut down on that consumptio­n by reducing its size by 75 percent and reducing component count by 20 percent.

To improve serviceabi­lity, Dell reduces the use of screws by 10 times over a convention­al laptop and components would use a keystone design that locks into place without resorting to glue. Of course, the laptop would be as modular as possible, and Dell is aiming for a total of 1.5 hours to take the laptop apart and replace components, including the screen and keyboard. The battery would be lithium iron phosphate, which has twice the life cycle of a traditiona­l lithium ion battery.

All this sounds great for sustainabi­lity nerds, but the moon shot might be how the

Concept Luna is upgraded and reused.

Rather than chucking a Concept Luna PC into e-waste or sending it out to be stripped for its precious metals when done, the motherboar­d could be removed from the laptop and replaced with a newer one. While you get to enjoy a newer, faster CPU in your system, you’d return the older motherboar­d to Dell, where the company could install it in a lowercost laptop for resale.

Obviously the new customer would know he or she is getting a laptop built with reused components, but Dell believes it won’t be an issue as parts such as the motherboar­d and CPU tend to be very durable well past their prime. That’s largely going to be the hardest part of Concept Luna—getting people to move from using and disposing of an entire laptop and instead shifting to a model of use, reuse, and reuse again until the individual component has lived its full lifetime before it’s easily recycled.
