Sí-Climate Systems

Sí-Climate Systems develops fully autonomous cooling, heating and water-infrastructure solutions based on natural, pressureless and electricity-free processes.

Our technologies — SíAir, SíWater, SíSand and SíHouse — enable buildings and villages that operate without air-conditioning, without heat pumps, without fuel and without batteries.

We focus on:

Passive cooling using ground-air & thermal mass

Long-term solar heat storage in water and sand

Decentralized drinking-water systems

Off-grid & infrastructure-light housing

Scalable solutions for Africa, Asia, Latin America & Mediterranean regions

This channel documents the development of our prototype village in Mallorca, technical modules, construction processes, field tests and international pilot projects.

If you work in renewable energy, off-grid systems, infrastructure development, sustainable housing or humanitarian projects — you are in the right place.
