Wow. Has it been a month already, since the last amazing breakthrough I heard about, concerning solar panels. Seems like i've been hearing stories like this since the late 90's. And, yet I still cant afford them. Sure, they are in my calculators... They are not in my car nor my house, nor any other car or house I see. I live in a pretty average middle-class neighborhood. What gives? I must have read over 30 articles like this in the last 5 years. (One every two months, I know) Why do I see rolls of these things in home depot for the price of a cheap carpet?
