In http://www.panaceauniversity.org/Chapter14.pdf it says "Peter was granted a New Zealand patent for his heater on 12th December 1944 but he found that after the war, the opposition from the utility companies was so great that it prevented him from going into commercial production with it. For fifty years, Peter kept up his attempts to get sufficient approval to bring his heater to the market place, but the opposition finally won and he never managed it" "the little guy being suppressed" always raises a flag or two So what's different now ? Utility companies are just as $$$$$$ hungry as they were, probably even more so -- http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist
