Now, even though I have been promoting eartn4energy for long time without actually knowing what it is, today, I decided to look into it's salespage, I understood that the problem people are not using solar panel is because it's too expensive and it takes 30 years to get the investment back, I believe it cost appx. $20,000 for installing solar panel, now, I can't f**king understand, if they can build 100+ million Iphone 4s and Ipad 3, when they were not that really important, why the f**k can't they build 500 million solar panels, and as we know, the more the product, the lower the cost it get, I mean, can't we reduce the cost of solar panel from $20,000 down to $500 or something, so that we can get our investment back in 1-2 months, and not only that, the world will be truly green, I mean, we can switch on the AC 24 hours and our parents won't even come and repeat everyday, son, have u switch off the AC ?
