Self charging battery.

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.

The idea

COVA began as a shared dream between four co-founders who asked: can we generate clean energy from the air itself? Frustrated by the limits of traditional energy, we set out to create a compact device that turns humidity into electricity. After months of testing and iteration, COVA was born a smart, sustainable solution designed to power the future using nature’s most abundant resource: air.

1. Install it

Put the COVA generator in your backyard or next to your home. It doesn’t need much space and blends in easily with your environment.

2. Connect

COVA is linked directly to your home’s fuse box. Once connected, it becomes part of your household energy system without extra effort.

3. Harvest

Using its special carbon and hydrogel technology, COVA captures humidity from the air and converts it into electricity. It works continuously, day and night, as long as there’s moisture in the air.

4. Power your home

The clean energy flows straight into your fuse box, powering everything from daily appliances to essential devices. It’s sustainable, reliable, and always ready when you need it.
