Here is a concise summary of the provided text:
**Title:** The World's Most Dangerous Candle (Ultra High Frequency Tesla Coil)
**Key Points:**
1. **Device:** An ultra high frequency (15 MHz) Tesla coil creating a plasma "candle".
2. **Unique Properties:**
* Cannot be blown out
* Attracted to grounded objects (e.g., humans)
* Can melt steel due to extremely high temperatures (up to 11,000°C)
3. **Electromagnetic Interference (EMI):**
* Trips Arc Fault Circuit Interrupter (AFCI) breakers in nearby houses due to induced high frequency currents
* Can be mitigated by placing the device on a conductive surface (e.g., concrete floor)
4. **Plasma Characteristics:**
* Appears as a whitish flame due to extremely hot air emitting a broad range of frequencies
* Can ionize and light up gases (e.g., helium, neon) and LEDs without direct contact
**Note:** The summary excludes promotional and concluding remarks (e.g., subscription requests, video links).
Here are the key facts extracted from the text, each with a number and in short sentences:
1. **Device Description**: The device used is an extremely high-frequency Tesla coil.
2. **Operating Frequency**: The Tesla coil operates at around 15 megahertz.
3. **Frequency Alternation**: The current alternates back and forth approximately 15 million times per second.
4. **Classification**: It's classified as an ultra-high frequency Tesla coil.
5. **Initial Power Issue**: Initial attempts in the kitchen caused breakers in the house to blow.
6. **Power Source Adjustment**: The device was connected to its own power source to mitigate breaker issues.
7. **AFI Breaker Tripping**: The device trips Arc Fault Circuit Interrupter (AFCI) breakers in the house.
8. **AFCI Breaker Function**: AFI breakers distinguish between sparks that may cause fires and regular sparks.
9. **Electromagnetic Pulse Effect**: The device sends out an electromagnetic pulse that can trip AFI breakers remotely.
10. **Concrete Floor Effect**: Placing the device on a concrete floor prevents it from tripping breakers.
11. **Plasma Flame Characteristics**:
* Attracted to grounded objects.
* Cannot be blown out.
* Much hotter than regular fire.
12. **Electron Temperature**: The electron temperature in the plasma flame can reach around 11,000 degrees Kelvin.
13. **Steel Melting Capability**: The plasma flame is hot enough to melt steel.
14. **Operating Principle**: Uses a very small amount of current but a very high frequency alternating high voltage.
15. **Lighting Capability**: Can light objects (like helium or neon tubes, or LEDs) by proximity due to electromagnetic waves.
16. **Plasma Color Variability**: The color of the plasma (air plasma) can vary from blue/purple to white, depending on temperature and ion ranges.
17. **Comparison to Other Tesla Coils**: Higher frequency coils produce a whiter flame, while lower frequency ones appear more blue/purple.
