DiodeArrayTechnology/NewExclusiveApplications Charles M Brown: I foresee there being first in position applications rather than exclusive applications. If a productive group develops an application it will start out as the exclusive source that keeps its lead as long as it does enough things right in good circumstances. The right tactics are probably apparent to everyone. I don't think maintaining exclusivity is important. If another group wants to enter the market the first company can sell its earliest small scale production equipment or some product made by the higher volume, cheaper unit cost equipment the first group has evolved to the new people so the new people can start small. Higher demand for a product can be met by many low production volume prodution lines, intermediate mixtures, or a few high production volume production lines. Diode arrays would supply scalable energy at low cost anywhere so factory equipment would be financially very liquid. Factories can be modular using shipping containers as modules.
hellekin: I was rather thinking of exclusivity as in: applications that can only be made with DA tech.
Charles M Brown: The diode array would make a lot of things easier. Preliminary brainstorming should be accepting of any workable application. Some of the new products may supersede others so further analysis is needed to filter good commercial prospects from the merely workable. The merely workable should be studied to some extent because they may be useful in other circumstances.
Diode arrays inside heat resistant containers would simulate perfect thermal insulation indefinitely autonomously. A diode array cooled tank of liquid helium could last for years within molten lava for vulcanologists. Diode array cooled fire resistant vehicles could drive through forest fires. Firesafes would be improved. An improvement in fire protection radical enough to be an exclusive application of the diode array would be the fire resistant binder or clipboard case.
Charles M Brown: Diode arrays would bring better conditions to squatters. Squatters would be able to work under safe reliable light at night or in deep interiors. Stoves and ovens would be safe and reliable. Safe reliable and quiet refrigerators would come in a great variety of sizes and purposes. A small cordless hotplate would be marginally practical, it would need to absorb heat in another part of itself to supply heat at the heating element. Perhaps a small combination stove and refrigerator with means to balance its power would be a useful answer. Freeze dried food would become widespread. Fresh water supply and sewage removal would be easier. Autonomous power tools would help people repair and construct material comforts. Reliable radio and video would assist in fire, police, and medical emergencies. Comfortable, low cost, nomadic camping would be possible in Hawaii.
Watercraft would be improved by diode arrays. Fuel would not be needed. Streamlining would be less critical.
Purification will become cheap. Semiconductors are often purified by zone refining where a narrow molten or gaseous zone is moved through the material several times. At present, energy has to be supplied to heat the material which is not recovered when the material cools. Diode arrays would recycle the heat when the material is cooled. Only a small amount of energy due to the removal of minor constituents would need to be imported or exported from the process.
Cheap purification leads to cheap photovoltaic panels but diode arrays would overwhelmingly superceed photovoltaic panels in utility. Improvemetes in large pannel fabrication remain important for chip substrates, antenna arrays, thin video displays or lighting panels.
Movie studios would cost little to light and cool. This would make it easier to make movies.
