Materials like quartz and corian have low thermal conductivity that make them ideal materials to be used in combination with a technique called inductive coupling. This technique can be used to wirelessly charge devices that support it or with the addition of wireless charging cases and adapters.
This design uses quartz as a base material for a bus shelter, integrating multiple charge ports into the seats. People who rely on public transit spend a lot of time at bus shelters and terminals, making them an ideal structure for public charging stations. Solar panels on the roof of the shelter supply power.
However wireless charging could prove to be a security issue (phones and tablets being stolen) in a public setting and not everyone will have the hardware available to use wireless charging, so outlets have been included into the design under the seats.
