Director Davis Guggenheim eloquently weaves the science of global warming with Al Gore’s personal history and lifelong commitment to reversing the effects of global climate change in the most talked-about documentary at Sundance. An audience and critical favorite, An Inconvenient Truth makes the compelling case that global warming is real, man-made, and its effects will be cataclysmic if we don’t act now. Gore presents a wide array of facts and information in a thoughtful and compelling way: often humorous, frequently emotional, always fascinating. In the end, An Inconvenient Truth accomplishes what all great films should: it leaves the viewer shaken, involved and inspired.
I made this solarpanel using: one layer og glass, one layer of eva (str photocap), then solarcells in strings ‘face down’ , and last layer of eva. I think the best method must be solarcells ‘face up’, and use acrylic backplate. i can not recommend to make solarpanel with acrylic backplane, use aluminium or wood instead as backplane.
