The Future of Power Is Already in the Air
COVA: electricity born from humidity.


At Cova, we believe the future of energy should be natural, clean, effortless, and an integral part of everyday life. We are a team of people who care about building a world where powering your home does not come at the planet’s expense. Our goal is simple: to make energy something you can rely on without even noticing it, because it is always there, quietly working in the background.
That is why we are creating Cova, a technology that turns the air around us into reliable electricity: no noise, no hassle, just sustainable power whenever you need it. For us, sustainability is not a trend or a buzzword; it is about leaving things better than we found them and making sure tomorrow feels brighter for everyone.

Every contribution matters.
every €5 cuts about 1 kg of CO₂ emissions. Small share, lasting impact.
We are not replacing large power systems.
We are redefining micro power, continuous electricity for sensing and transmitting small data signals.
The world is filled with sensors, monitoring temperature, humidity, air quality, pressure, and movement across buildings, factories, farms, and homes. But most of these sensors still rely on batteries, making large deployments expensive, slow to maintain, and wasteful. As a result, many sensor networks are never installed at all, simply because powering them is the biggest barrier.
There is always some moisture in the air, even when we don’t notice it. When this moisture comes into contact with the COVA layer, water molecules naturally bind to its surface and create a gentle flow of ions within the material. This ion movement generates a small but steady electrical signal. As long as the device is exposed to air, the COVA layer continues producing power on its own.
