In a perfect world, we would slowly wean ourselves off fossil fuels and embrace green technology. The thing is that it's hard to let go of them when we can't find green alternatives that provide as much power. Dye-sensitized solar cells promise to bring solar cells to everyone cheaply...
French designer Léa Longis created this amazing-looking radio, that works purely on solar cells. If that were it, this might get boring quickly. But, as you might have guessed, it isn't. This design uses dye-sensitized solar cells, which were developed by Michael Grätzel.
These types of cell promise to make solar cells very cheap, since they use low-cost materials and they do not need an elaborate manufacturing process. In large quantities, they should be significantly less expensive that other types of solar cells. They can be made into flexible sheets that are robust, and they require no protections for minor scrapes, like hail or trees. Their conversion efficiency is poorer than regular cells, but their price-performance ratio is high enough to allow them to compete seriously with fossil fuel alternatives.
The Hélio DAB Radio uses these colorful solar cells to power all of its functions. These panels get their color from vegetable ink. The psychedelic radio's solar cells are printed onto thin glass panels, enabling them to capture the ambient light that is prevalent in most rooms and harness it for power. The cells are on these panels that rotate around, kind of like the blades of a fan.
