The Water Problem
AI is thirsty. Here's the fix.
Our Impact — Live
Every dollar raised for clean water. Honest and growing.
$0raised so far
Just getting startedGoal: $1,000 → our first well
We show real numbers only. At $0, we say $0 — because honesty is the whole point. Watch it grow as JSTJO grows. 💧
Give directly — 100% goes to the charity, JSTJO keeps nothing
Goes to charity: water — pick a different one below and this follows.
Every AI answer has a hidden cost: water. Data centers run hot, and most are cooled by evaporating massive amounts of it. A short AI chat can use about a bottle of water. Multiply that by billions of prompts, and it adds up fast.

✓ We Did the Research — Here's Who's Solving It
These are the real companies and breakthroughs tackling AI's water problem at the source. Not vague promises — actual technology shipping now.
Ferveret · MIT startup
Nuclear-reactor-inspired cooling that submerges servers in a special liquid — achieving zero water consumption while boosting efficiency. No toxic forever-chemicals.
Corintis · backed by Microsoft
Puts microscopic cooling channels inside the chip itself — 10x better heat extraction, 50x more energy efficient. Cooling at the silicon level.
NVIDIA · Vera Rubin platform
Newest AI servers are 100% liquid-cooled in a sealed closed loop that runs hot — venting heat outside without water-guzzling chillers. Becoming the industry standard.
Submer · immersion cooling
Submerges servers in non-conductive liquid, eliminating air-cooling entirely — cutting both energy and water use, in compact modular builds.
Oracle & Microsoft · closed-loop at scale
Both deploying closed-loop cooling — fluid filled once and recirculated like a car radiator, not consumed. Microsoft says its newest centers use about as much water as a single restaurant.
The honest part
Better cooling slashes on-site water — but AI's electricity still carries a hidden water footprint from power generation. The problem isn't fully solved. But real progress is happening fast, and we choose to be part of it.
The shape of it
US data centre water use
billions of gallons per year · 2028 is a projection
Water per AI answer
the honest version is a range, and it depends what you count
Cooling only — what companies report~0.3 mL
Add the electricity's water10–50 mL
That gap is the whole story. Nobody is lying about the small number — they're just not counting the rest of it. We count more, not less.

JSTJO's Commitment
JSTJO runs on AI — which means JSTJO is part of this too. We don't hide from that. JSTJO commits to building responsibly: spreading awareness, choosing water-efficient infrastructure as we grow, and giving back to clean-water causes as the platform earns. You shouldn't have to choose between building the future and protecting the planet.
💧
5% of every subscription helps fund clean water.
You're not just building your world with JSTJO — you're helping protect the one we all share. And our pledge only grows: the more JSTJO thrives, the more we give. We started at 5% — and we're just getting started. 🌍
You Choose Where It Goes
Two ways to make an impact — you pick the one that speaks to you. Help people who need water now, or fund the research fixing the problem at its source. Either way, you direct the good.
🌍 Help People In Need — water access + conservation
🔬 Fix It At The Source — water-tech research
Note: the big cooling companies (NVIDIA, Microsoft, etc.) are for-profit — you can't donate to them. So "fix the source" supports independent research nonprofits and university programs actually solving it.
There's always good in bad. We choose to be part of the solution. 💧

WHY DROPS
THE MATH, SHORT
One answer costs roughly 2–25 mL of water —
2 if you count only the cooling at the datacentre, 25 if you also count the water used
generating its electricity. Nobody can measure your specific query, so this is a
coefficient, not a reading.
