IBM makes strides in reducing the cost of solar power
The largest obstacle involved with focusing solar energy into smaller areas lies with the intense heat produced. This is something we learned as children, sitting on the sidewalk with a magnifying glass in hand. But recently, IBM has taken the reins on the issue, utilizing some of their own heat-dissipation technology they use in their computer hardware for the solar energy field.By focusing the sun over 2300x, they were able to generate 70 watts of usable electric power out of one square centimeter of silicon photovoltaic panel. This is a vast improvement over the previous attempt by Sungri at 1600x. The heat problems, size of the concentrator itself and the cost are all factors against this amount of power being practical now, but the more efficient and powerful these large companies like IBM can get solar power, the lower the cost will evolve for the normal consumer like you and me.
