      Since it takes a lot of energy to isolate Silicon from sand, these days the blue-colored silicon (sometimes with psychadelic paterns) is obtained by meting the electronics devices from these junk systems thrown in the garbage dump. For Silicon cells although such polycrystalline materials do not have 99% purity as in the case of Mono-crystalline wafer material. the lack of 99% purity of Silicon only decreases the Efficiency by a very slight margin, when one compares the cost. Most recycled Silicon ends up in producing Solar Cells., which lowers the effective cost of Solar Modules. But both Mon- and Poly- Silicon Solar Modules function quite well for over 20 years.
      The Amorphous-Thin-Film Silicon behaves in quite different ways, and although many manufacturers guarantee these modules for 10 years, their performance begins to degrade after about 6 years, just like one observes the Colored drapes fading in color exposed to sunlight after some time.

      And don't forget surveys.... Do not trust the surveys.... They will be used against you. If president Bush succeeds at releasing the marketing companies from liability and making this retroactive people will be in a world of hurt and I mean this literally!  Do not participate in surveys and if it is a reputable company.... even less! I repeat, the surveys will be used against you.

Radio is mostly scripted so it is also out. Television is made from pictures and I like pictures, and each of which incidently, I have heard are worth a thousand words. But those words only have worth if spoken since if they are ever written down they are again out. Network TV comforts me. I have no debt, and what is a library? And did I tell you I read somewhere that you can't trust what you read?

      perhaps the best strategy to improve  the media input in your household and save money at the same time is to send the old TV set to be recycled and use the replacement money [$600.00 stimulis check?]  on paying down your debt.
      Remember in the '60s when the Federal Communications Commission Director called network television in the US a "vast wasteland"? Well nothing has changed except that it has become a much more profitable and extensive wasteland. The old adage "Kill Your Television" is more relavent than ever. Get your family library cards...use them. Get your news from the www and newspapers, especially weekley and business journals and numerous resources. The TV should be near the bottom of "information" sources.

      Subject: [hreg] Flat Screen TV Energy Usage Spreadsheet
      My 32" boob tube is showing signs of failure so I have an excuse to buy a 'cool' new Flat HDTV.
      Cool has a dual meaning here. Cool meaning just plain cool, as in 'Look at my cool new TV' and cool meaning low energy consumption. Electrical inefficiency is directly proportional to waste heat generated by an appliance in my home that my AC must then burn even more electricity to remove.
      So being a green engineer I naturally start with HDTVs 2007 models ranked by energy usage. I copied this from CNET then deleted too small and too big models (for my needs and budget). Then I deleted all the  'poor' performers, some of which used 4 times the energy of the same size model.  Note that almost all are LCD with only 1 plasma TV remained on my list.  The model names in the spreadsheet should still have the link back to CNets general ranking and performance scores for each model.
      I will probably cross reference these to the latest Consumer Reports ranking and then finally price. At that point I will have the 'Nirvana' of flat screen TVs.
      Maybe a fellow HREG is in the same stage.  (If not put a big magnet on the back of your TV like I did when my wife was not looking)
