Exploring COP in Magnetic Induction Heaters Powered by Non-Electric Drive Systems

I'm opening up a discussion to investigate the Coefficient of Performance (COP) of magnetic induction heating systems powered by various non-electric sources, such as Stirling engines, efficient electric motors, Tesla turbines, and gas pressure drives.

Magnetic induction heating, traditionally powered electrically, is known for rapid, efficient heating by generating eddy currents in conductive materials. However, adapting it to non-electric drive systems could unlock new levels of efficiency, especially in scenarios where direct electricity is limited or where sustainable power is a priority.

Key Goals:

Define COP for magnetic induction heaters driven by different power sources.
We aim to measure input in mechanical or electrical units (volts, amps, watts, RPM, etc.) and compare them with output heat energy.

Measure Heat-Up Time to reach maximum temperature.
Measure electric volts amps watts in 
Measure max heat out and most important time to reach max
Time-to-heat data is crucial for accurate COP calculation and comparing the effectiveness of each drive system.
Compare System Efficiency across different non-electric drives:
Stirling Engines: Known for high thermal-to-mechanical conversion efficiency and minimal emissions.
Tesla Turbines: Highly efficient for specific mechanical output profiles, particularly with pressurized gas or steam.
Efficient Electric Motors: Testing performance with high-efficiency designs to see if electrically driven induction can still perform competitively.

Gas Pressure Drives: Assessing if direct gas pressure can provide a feasible induction system with rapid heating.

Key Metrics to Capture:
Power Input (Volts/Amps/Watts): To assess and calculate power consumption.
Max Heat Output: Temperature achieved in the heating medium (copper tube, steel rod, etc.).
Time-to-Max Heat: Crucial for evaluating the practicality and effectiveness of each drive.

How You Can Contribute:
Share data from experiments or research on non-electric magnetic induction setups, especially those driven by Stirling engines, Tesla turbines, or similar methods.
Discuss design challenges and solutions, especially around transferring mechanical motion to magnetic induction with minimal loss.

Offer insights into alternative designs or materials that improve COP.

Questions to Kick-Start Discussion:
Which drive system has yielded the highest COP in your experience?
How does heat-up time compare between electric and non-electric magnetic induction?
What strategies improve heat transfer and energy conversion for induction when avoiding direct electric input?

Let’s work together to uncover the best configurations, measure COP accurately, and perhaps redefine the way magnetic induction heating can be applied in sustainable, off-grid, or specialized industrial scenarios. Looking forward to your insights, data, and ideas!

Using heat to make heat is an interesting setup, especially when combining Stirling engines and magnetic induction heating systems. Here, the system would work by converting heat into mechanical energy (using a Stirling engine), which then drives a magnetic induction system to generate heat again. This cycle could create a relatively self-sustaining system, with applications in off-grid or closed-loop heating solutions.

System Overview
Heat Source for the Stirling Engine: The system begins with an external heat source, such as a combustion fuel, geothermal heat, or concentrated solar energy. This heat powers the Stirling engine.

Stirling Engine: Converts heat into mechanical energy with an efficiency of around 20-40%, depending on temperature differential. The engine drives a rotating magnet, spinning it over a conductive material.

Magnetic Induction Heating: The rotating magnet induces eddy currents in a conductive material (e.g., a copper tube or plate), generating secondary heat for the target (such as a water tank or heat exchanger).

Discussion Invitation
This setup has potential for sustainable heat applications but requires further research to understand:

How to maximize the COP in practical setups.
Ideal Stirling engine designs that maintain efficiency at various temperature ranges. above 40%
Magnetic induction coil configurations that achieve higher efficiency and faster heat-up times. above 80% 60 secs
join cop of 0.55 and above 21 to 2,5 cop

For example, if an alternator receives 100 kW of mechanical power and produces 85 kW of electrical power, the efficiency would be:
Efficiency=85 kW100 kW×100=85%\text{Efficiency} = \frac{85 \, \text{kW}}{100 \, \text{kW}} \times 100 = 85\%Efficiency=100kW85kW×100=85%
In real-world applications, the efficiency of alternators typically ranges from 85% to 95%, depending on the design, size, and operating conditions. Larger alternators designed for industrial or power generation applications tend to have higher efficiency due to optimized designs and better materials.

So One would expect same or Better from a Non Electric Magnetic Induction Heater

Lets measure some and put some number in the world for others to improve on
