Tech: Canadian company makes nanowire solar cells

[dracodraconis]

Researchers at McMaster University claim to have developed a method for converting solar energy into electricity more cheaply and with greater efficiency than current methods. They grow nanowires on a semiconductor that collect and convert solar energy, resulting in the black appearance on the material shown in this picture. They haven't released estimates of cost per unit energy or conversion efficiency, but are  now working with a local company to commercialize the product.
