Solar camping lamps(skldintl)

PORTLAND, Ore. - They haven't figured out yet how to get the pruning done, but architects and federal officials plan one of the world's most extensive vertical gardens in downtown Portland — what amounts to a series of 250-foot-tall trellises designed to shade the west side of an 18-story office building.
It is not a new idea to use greenery vertically as "solar garden light," running plants up the sides of a building to keep it cool.
But even in a city with a reputation for rainfed greenery as well as for green architecture, the wall of the Edith Green-Wendell Wyatt Federal Building would stand out.
