Turning low-grade heat into water.
Pleione is developing modular thermal water recovery systems designed to couple low-grade thermal energy with advanced sorption and condensation processes. This page is candid about what is proven, what is partnered, and what is still being validated.
We don't sell the material. We own the system.
We are developing next-generation thermal water recovery using advanced sorption materials, including MOF-based architectures, designed to operate from low-grade thermal energy. The active module is a replaceable cartridge. Today it might use one sorbent; tomorrow another, or membrane distillation, or a hybrid. Guardian determines which technology belongs inside the Node.
The opportunity is real and condition-dependent. Researchers have reported sorbents such as CAU-10-H capturing water at relative humidity ≥18% and releasing it near 70 °C, with reported production around 1.8 L/kg/day under stated conditions; recent work identifies data-centre waste heat as a source for sorption water systems. We treat these as third-party findings, not Pleione performance.
The engine is replaceable.
The active recovery module is a serviceable cartridge with nine functional stages. Guardian recognises a new one the moment it seats and loads its optimization profile — hardware opens the account, the cartridge and service make it recurring.
Illustrative telemetry. Values are simulated until the first cartridge runs.
Water chemistry in. Treatment architecture out.
Give Guardian a source, a flow, a chemistry and the heat available, and it composes the recovery train.
Every plan is written to the ledger before it is executed, and the constraint layer must clear all twelve rules first.
A meets the spec at a third of B’s energy. B is held in reserve and selects automatically if conductivity passes 780 µS/cm. C fails the microbial margin.
Under active engineering and validation.
Designed to utilise low-grade thermal energy. Waste heat does not create water — it powers the recovery of water that already exists in the facility's own streams and, where the climate supports it, from the air. Performance varies with temperature, humidity, airflow, water chemistry and configuration. Every litre carries its source, its energy input and its chain of custody.
