Electrical Power Stirling Engine Magnesium fuel? 1

Why 24hrs power and no emissions.
A while back I did a form on power a Stirling on (lower power) heat source that was not sufficient for electoral power.
Now I am back with new idea can you make a custom Stirling engine using magnesium burned as fuel to power 10KW of power?
What health precautions will you take ( Magnesium Oxide)?
Reputable machine shop to create the parts (have to withstand high temperatures?
Any thoughts appreciated?

Sure, but you really shouldn't.
This is a Stirling so reaction would be outside engine just heating the plate?
Do you have other chemicals would you experiment with for power?
This is just conceptual ideas so open to any for experimentation?

If you want heat energy there are all sorts of things you can burn or react. Pretty confident there aren't any that haven't already been considered and rejected.
 
The ability to control, and stop, the fire after it's started might be important to you.

Have you thought about the size of the fire you'll need to get 10 kW out of your system?
 
Back waaaayyyy up until you can see the big picture and the main objectives - "obtain X amount of electrical power for Y time in Z environment" - and it will almost certainly be found that a bulky and inefficient-in-the-real-world Stirling engine running on a high-risk inefficient-to-produce material as "fuel" will be a sub-optimal solution, and probably by far.

"just because you can, doesn't mean you should"

You'll have to excuse me while I run an errand in my battery-electric vehicle ... somewhere deep inside that battery, lithium "fuel" is being combined with a chemical "oxidizer" in order to quietly produce electrical power at very high efficiency relative to the electrical power that was put into it yesterday while it was plugged in.

Maybe your application is different that warrants using a complex, inefficient mechanical solution using a risky energy source. Explain us.
