A Tesla coil is a radio frequency oscillator that drives an air-core double-tuned resonant transformer to produce high voltages at low currents. Tesla's original circuits as well as most modern coils use a simple spark gap to excite oscillations in the tuned transformer.
Proton-exchange membrane fuel cells, also known as polymer electrolyte membrane fuel cells, are a type of fuel cell being developed mainly for transport applications, as well as for stationary fuel-cell applications and portable fuel-cell applications. Their distinguishing features include lower temperature/pressure ranges and a special proton-conducting polymer electrolyte membrane. PEMFCs generate electricity and operate on the opposite principle to PEM electrolysis, which consumes electricity
Program Objective Memorandum. WHAT IS A POM? A POM is a central component of the Programming phase of the PPBE, when planning decisions, programming guidance, and congressional guidance is converted into a detailed allocation of resources. The Program Objective Memorandum (POM) is used to submit programming proposals. Submitted by the services in even-numbered On Budget years to develop proposed programs consistent with the Joint Programming Guidance (JPG) and to submit proposed programming, the POM includes an analysis of missions, objectives, alternative methods to accomplish objectives, and allocation of resources.
