Back in 2016, MIT’s Media Lab installed a quirky vending machine that’s become a bit of tech lore: it exclusively stocked Soylent (the meal-replacement drink/shake) and accepted payments only in Bitcoin via a scannable QR code. This wasn’t your average snack dispenser—it was a forward-thinking experiment in crypto payments, perfectly suited to the lab’s innovative, future-of-food-and-finance crowd. No cash, no cards—just BTC for your nutrient-packed bottle.
What It Was
- Concept: A standard-looking vending machine retrofitted for Bitcoin, dispensing bottles of Soylent 2.0 (the vanilla or chocolate ready-to-drink version at the time). Users scanned a QR code with their wallet app, sent the exact BTC amount (adjusted for real-time exchange rates, around $2-3 per bottle), and grabbed their drink. It highlighted early crypto adoption in everyday scenarios, blending Soylent’s “food as tech” ethos with Bitcoin’s decentralized vibe.
- Purpose: Spearheaded by Media Lab folks (including director Joi Ito), it was a demo of seamless, low-friction crypto transactions. As one report quipped, it was “the vending machine that survives the robot apocalypse”—stocked with sustenance for coders who might not surface for days.
- Tech Twist: Powered by simple blockchain integration; no fancy Lightning Network yet (that came later in MIT demos). It even tied into broader lab projects on digital currencies.
When and Where
- Launch and Timeline: Debuted around mid-2016 (first buzz in July), after months of hype on social media. It was a semi-permanent fixture but likely phased out as tech evolved—by 2017, mentions faded, and no signs of it running today.
- Location: Right in the MIT Media Lab building (E14 on the Cambridge, MA campus), down the hall from project spaces. Easy access for students, researchers, and visitors fueling late-night hacks.
- Availability: Bottles were always limited (photos show it half-empty), emphasizing exclusivity over mass sales.
Impact and Legacy
This machine sparked viral chatter for symbolizing a dystopian-yet-cool future: crypto-fueled, Soylent-sustained efficiency. It inspired other Bitcoin vending experiments worldwide but stayed niche. Fast-forward to 2025: MIT’s still crypto-forward (e.g., their Lit software for Lightning Network payments), but you’ll find regular snack machines on campus now. Soylent? Widely available online or at MIT co-ops, payable in USD (or BTC via some retailers).
