November 1976 RAIN Page 17 -SHOW RAIN TO A FRIEND! We'd like to ask a favor of all you RAIN readers! Help us connect RAIN up with people who can make good use of its treasures. You are an importaryt link in improving our ef-· fectiveness. We want to increase the number of RAIN subscribers to the point (5,000) where the magazine will pay for its produc~ ,tion and pay a subsistence salary ($400/month) to those who put it out. At pre·sent your subscription pays for production costs but it doesn't pay any of us. We have to earn money doing other work, which is okay and keeps us honest, but it also means we can't do many things we feel are important. *We want to get RAIN out to more people who can make good use of it-not just build up a lot of "readers"-but don't have the time, money or connections to do so. *Having to spend 60-80 hours a week doing other jobs to earn a living and doing all the rest of RAINwork besides writing and information networking means we don't have as much time or energy to do as good a job as we'd like getting new things together for you. It also means we're likely to burn out on doing this, which shouldn't have to happen. *We'd like to be able to train other people to put out publications, to take over RAIN, bring in new views, cover new areas, and replace us so we can get new projects going that can help expand and extend the things we are all working on. But we can't realistically expect every good person to be willing to If each present RAIN subscriber would connect up three new subscribers with RAIN, we'd be there. You're the most effective way we can think of to.introduce RAIN to new · people. You know us, and hopefully find something useful in us, and you collectively know many times more good people than we do that could make good use of RAIN resources. Any other form of locating new subscribers takes mone-y (which ultimately is reflected in subscription costs), lots of our time and isn't either a very effective or right way to grow a network. So give us a hand: *Show RAIN to your friends, and get at least three to subscribe. work an extra job to be able to do RAIN. _ * Give a gift subscription to someone who can use it. * Clone yourself and subscribe again. Your personal recommendation of RAIN to a person is important. Without someone they trust suggesting something, most people need two or three different turn-ons before they will really take a careful look at something. *We'd like to be able to demonstrate that a network-supported information service can be economically self-supporting and can provide a viable alternative to advertisement-supported publications. THEREILL BE A .HEAT PIPE ·IN YOUR FUTURE Line the inside of a metal tube with a wick from a kerosene lamp, saturate the wick with water, evacuate the tube, seal both ends, and you have a heat pipe. Dip one end in a pot of boiling water and within a few seconds the other end will be too hot to handle.. Basically, a heat pipe is a super thermal conductor that transmits heat by the evaporation and condensation of a working fluid. It can transfer about 1000 times.more heat energy than copper, one of the best known copductors and do it with a temperature drop of less than 3°F. per ft. Heat pipes have no moving parts, require no external energy (other than the heat they transmit), are reversible in operation, and completely silent. And, like any piece of tubing or pipe, they are rugged and can stand lots of abuse. Already in use in medicine, nuclear reactors, space flight and as hear-sinks in electronic equipment, the energy crisis and the increasing demand for more efficient use of fuels is prompting renewed interest in heat pipes for waste heat recovery and solar energy collection. Since you'll soon be seeing and hearing more about heat pipes, we've selected a few articles that will introduce you to their theory and applications and listed manufacturers who supply them: "Heat Pipes: Breakthrough in Thermal Economy?" by Charles Behrens, in Appliance Manufacturer, Nov. 1973, pp. 72-75. "How Heat Pipes Work" by Don Noren, in Chemical Engineering, August 19, 1975, pp. 89-91. "The.Heat Pipe," by G. Yale Eastman, in Scientific American, May 1968, pp. 39-46.
