2. Induction lamp - Wikipedia

   en.wikipedia.org/wiki/Induction_lamp

   Plasma lamps are a family of light sources that generate light by exciting a plasma inside a closed transparent burner or bulb using radio frequency (RF) power. Typically, such lamps use a noble gas or a mixture of these gases and additional materials such as metal halides , sodium , mercury , or sulfur .

3. Inductive output tube - Wikipedia

   en.wikipedia.org/wiki/Inductive_output_tube

   The inductive output tube (IOT) or klystrode is a variety of linear-beam vacuum tube, similar to a klystron, used as a power amplifier for high frequency radio waves. It evolved in the 1980s to meet increasing efficiency requirements for high-power RF amplifiers in radio transmitters. [ 1 ]

4. RF module - Wikipedia

   en.wikipedia.org/wiki/RF_module

   An RF module (short for radio-frequency module) is a (usually) small electronic device used to transmit and/or receive radio signals between two devices. In an embedded system it is often desirable to communicate with another device wirelessly .

5. List of vacuum tubes - Wikipedia

   Some specify which end of the filament is to be powered by the positive side of the filament power supply (usually a battery). All have glass bodies that measure from 0.285 to 0.400 inches (7.2 to 10.2 millimetres) wide, and from 1.25 to 2.00 inches (32 to 51 millimetres) in overall length.

6. Gas-discharge lamp - Wikipedia

   en.wikipedia.org/wiki/Gas-discharge_lamp

   The lamp consisted of a Geissler tube that was excited by a battery-powered Ruhmkorff induction coil; an early transformer capable of converting DC currents of low voltage into rapid high-voltage pulses. Initially the lamp generated white light by using a Geissler tube filled with carbon dioxide. However, the carbon dioxide tended to break down.

7. Wireless power transfer - Wikipedia

   en.wikipedia.org/wiki/Wireless_power_transfer

   A human safe power density of 1 mW/cm 2 distributed across a 10 km diameter area corresponds to 750 megawatts total power level. This is the power level found in many modern electric power plants. For comparison, a solar PV farm of similar size might easily exceed 10,000 megawatts (rounded) at best conditions during daytime.
