Science Experiment: Oscillation.
To demonstrate oscillation:
1: Place trouble light under car. Be sure to remove guards so quartz lamp is fully exposed.
2: Crawl under car. Make sure engine is warm, and exhaust system is hot.
3: Roll onto quartz lamp
4: Leap away from quartz lamp, driving forehead into red-hot catalytic convertor
5: Scream, fall back onto quartz lamp
Repeat 4 and 5.
Process is stable until pain receptors fail or subject escapes.

LOL! You really know how to live! I’m jealous!
Now let’s see, place trouble light under car….
Heh. I’d think eventually your forehead and body would absorb the heat until your reactions would minimize. If you survive long enough.
the thing people do for science… ;)
That’s why Step One in working on a car should be “Open Beer”. Step Two should be “Drink Beer”. Lets things cool down a bit :)
Forget solar and geothermal, this looks like a perfect thermal-to-mechanical energy conversion mechanism.
Ouch.
I’ve done the same thing with my head stuck between an F100 engine gearbox and the inner bulkheads of an F-15C. Hit, sizzle, hit, sizzle, etc.
Makes for a great story years later, but a horrible evening.
