How the conversion of light into electricity or hydrogen works

Photovoltaic paint captures sunlight and converts it into electricity. Think of it as a plant that uses light to grow. Instead of leaves, the paint has special materials like titanium oxide.

These materials take sunlight and change it into electric current. It's an efficient way of generating electricity without big panels on the roof.

To make hydrogen, another paint uses moisture in the air. This paint takes the water in the air and splits it into hydrogen and oxygen with the help of the sun. The hydrogen can be stored and used as an energy source.

It's like separating the ingredients of a recipe for later use. This technology could revolutionize the way we produce and use energy in our homes and cars.
