| Amanda Riphnykhazova <licensedtoquill@gmail.com>: Mar 27 02:56PM -0700 About 25 years ago I bought a baseballs hat with a solar panel on the top which drove a fan motor. It looked terrible and never moved enough air onto the user's forehead to actually do anything. After a while I got the impression that the panel was no longer giving out ANY power. I wonder if it might be possible to replace the 25 year old solar panel with a more modern one which actually works? Possibly a flexible panel which goes round the head a bit? What values should I try looking for? Or am I kidding myself that I might get this thing to work? Is that why no one has tried putting these things back into production? |

Solar cell efficiency certainly has improved, but not enough (in the cells available to you) to make any difference in that gimmicky hat. |
| Amanda Riphnykhazova <licensedtoquill@gmail.com>: Mar 28 08:06AM -0700 So, even after 25 years of solar panel development, the most i can expect (if I replace that el-cheapo rectangular panel at the top) is to restore it to its former lousy operational state? |

Are you sure the problem is a wimpy solar panel? Does the fan blow adequately if you power it from batteries? If you look on ebay, you can find lots of sellers of solar cells, fans, and caps, both separately and combined. |

Phil That's not a terrible idea, but, I would try searching Ebay and zip through several hundred pictures of amplifiers, one might pop out at you. Mikek |

Too bad, actually quite a few amplifiers had that feature, my wife's parents had one in Florida. -- Thanks, - Win |
| "Ron D." <ron.dozier@gmail.com>: Mar 27 11:58AM -0700 My laser printer is in the basement. I have to store my unused paper in a heated part of the house or it may jam. It's OK, if it's in the printer. There is a "curl" to the paper and the printer feeds better one way. So, flip and rotate sometimes helps. Humidity affects paper. You have pick-up and separation. |
