bi-metal shade
this idea is based on thermo-bi-metal, which changes it’s form when exposed to heat, like in this lamp:
so why not use this as umbrellas that extend like flowers in the sun. This could either work directly through the heat of the sun, or indirectly through solar panels that put a current to the metal sheets.

light pole
we saw the cable supportet street lights that were all connected to a pole in the middle … why not light up this pole? And also the cables … they are already “conected” to power!
