We discovered that the world's largest freshwater source isn't underground.
It's in your exhaust pipes.

Everywhere industry burns energy, it also discards heat. We built the first material system that converts this waste heat into water — at the exact temperature your infrastructure already runs at.

Industry wastes more energy as low-grade heat than all of Europe consumes in a year. Until now, it was worth nothing.

Data centers are where both collide. They produce enormous quantities of low-grade waste heat — and they consume, and are increasingly denied, the water they need to stay cool. RBV converts one into the other.

If freshwater access is a risk for your next site, we can eliminate it.

We are currently engaging data center operators about pilot programs in Europe and North America.

"Currently, we have a community backlash issue on the amount of water that we use." — Data Center Director, Stack Infrastructure, Virginia

45–50 °C. That temperature is the entire thesis.

It is the range at which waste heat is already leaving your cooling circuits. Our sorbent captures water vapour from ambient air and releases it as liquid the moment that heat passes through. No fuel, no vacuum, no additional energy input — we run on what you currently discard.

Capture vapor from air

The sorbent draws water vapour from ambient air — from 35% relative humidity, the standard for most data center climates.

Regenerate with waste heat

Server exhaust heat — already being thrown away — triggers full release. No competing with existing thermal systems.

Condense into liquid water

Released vapour condenses immediately into clean liquid water. Fast cycle — continuous production, no batch delays.

Feed the cooling loop

Water feeds directly into your existing cooling infrastructure. Zero freshwater grid withdrawal. Zero community conflict.

The 45 °C insight changes everything.

The fuel is already there.

Direct-to-chip cooling loops exit at 40–55 °C — the exact temperature required to fully regenerate RBV's sorbent. No vacuum. No additional energy source. The heat your infrastructure currently discards becomes the engine of water production.

One connection. The rest stays exactly as it is.

Existing cold plates, CDUs, and cooling towers operate unchanged. RBV connects at a single point in the existing loop and changes only the source of makeup water — from the municipal grid to the atmosphere above the facility.

European, by design.

Stricter water regulation, the fastest data center growth, and binding ESG deadlines create the most acute non-monetary cost of water dependence in the world. RBV is European and built for the regulatory moment that is already here.

Data centers open the door.

The same physics works in steel, chemicals, pharma, and food production — every industry that wastes heat below 80 °C and consumes water. The first pilots in data centers write the operational playbook for what comes after.
