More cool stuff from Canada.

"Buildings of the future could be "clothed" in a flexible, power-generating material that looks like denim. The Canadian company developing the material says it can be draped over just about any shape - greatly expanding the number of places where solar power can be generated.

The inventors hope their power-generating material will enable architects to design complex, curvy buildings that can nevertheless carry solar cells. One day, consumer products such as personal stereos and cellphones might also harness "denim-power" to charge their batteries.

Unlike conventional solar cells, the new, cheap material has no rigid silicon base. Instead, it is made of thousands of inexpensive silicon beads sandwiched between two thin layers of aluminium foil and sealed on both sides with plastic. Each bead functions as a tiny solar cell, absorbing sunlight and converting it into electricity. The aluminium sheets give the material physical strength and act as electrical contacts.

The idea comes from Spheral Solar of Cambridge, Ontario, which acquired patents on the concept in 1997. Spokesman Milfred Hammerbacher expects the company to start making its flexible panels next year."
