Electron Stimulated Luminescence (ESL)
http://phys.org/news172341986.html In December 2011, Lowes will begin carrying a new cathodoluminescence or Electron Stimulated Luminescence (ESL) R30 light bulb by Vu1 Corporation. The flood light is expected to retail for $14.98. Cold cathode technology has come to the foreground with the discovery of carbon nanotubes – nature’s ideal cathode technology. ESL technology works by firing electrons at phosphor, which then glows. As Vu1 explains, the technology is similar to that used in cathode ray tubes and TVs. However, the bulbs have several improvements, such as in uniform electron distribution, energy efficiency, phosphor performance and manufacturing costs. “CRT and TV technology is based on delivering an electron ‘beam’ and then turning pixels on and off very quickly,” the company explains on its website. “ESL technology is based on uniformly delivering a ’spray’ of electrons that illuminate a large surface very energy efficiently over a long lifetime.” >From the time, carbon nanotubes have been discovered; cold cathode technology has come to the forefront, which the company wants to utilize for attaining better efficiency, highly accurate turn on times, simpler electronics and lower cost. I am very lazy, why reinvent the wheel when all the work has already been done for us. It is a pain in the butt to build our own nanotubes for our cold fusion reactor. It might be possible to repurpose an existing device to do what we want. At $15 it won’t cost us much to try. The cold cathode technology uses a nanotube based electron emitter to stimulate a phosphorous screen. We might be able replace the phosphorous screen with a thin layer of nickel nano-powder. Then use this nanotube based cold cathode to push electrons onto nickel nano powder that is enclosed in a high pressure hydrogen envelope. This is the kind of thing NASA (and maybe the Navy?) is doing on their chip.
