[...] What a great idea. I'll bet Jay has never even thought of that or done any type of a cost/benefit analysis. ![]() Interesting cost/benefit for one case. ~7 year to pay for it. http://www.pbs.org/wgbh/nova/solar/house.html Obviously it's a stretch to apply it to all houses. Interesting show, nonetheless. Entire show is he http://www.pbs.org/wgbh/nova/solar/program.html Thinking of checking out one of the houses that's featured in the show (Somerville is one town over from where I work). =============== I remember playing around Freshman year in college ('80). I was a tech theatre major and 'borrowed' one of the Fresnel lenses. Found a beat up old car radiator in the garage. Cut a 55 gal. drum in half, painted the inside black, filled up the radiator with water, and proceeded to set the el-cheapo experiment into motion. Took about a minute, and the pressure built up enough that you could hear the metal stressing out. The tranny lines, which were cut and bent, began to straighten out. We took a few steps back. 30 seconds or so later, and what little tranny juice had remained, shot out fairly rapidly. We took a few more steps back. Finally, the radiator just failed completely, as steam shot at high pressure from whatever new orifices were being created. We concluded: Stupid solar, might as well abandon this. Damn old rusted cheap, sitting in the garage for 10+ years, radiator. Waste of time... let's go do something constructive, like take the dirt bikes out again... Yeah, we were down a few quarts, so had to be properly oiled (heh) beforehand, to ensure an nice uncontrolled experiment :P Regards, Jon |
