Stirlings heating cone

 On a lamp

So you mount a large diameter stirling engine on top of a light. Turn the light on and the engine will spin. Attach said engine to a generator which powers a heating coil.Place said coil at the top of the engine. Now on top of the first stirling engine place another engine (of a smaller diameter) and have it power a heating coil. repeat until you cannot physically make a smaller stirling engine.

       Then what? You could probably warm a space with the heating cone. Plus it would be cool to watch operating. And the glow of the heating coils.

       Bone from me. That bottom light is too bright. It hurts my eyes, or would, if it were real. Plus that top one is not even a Stirling engine. It looks like a little tub of maple syrup, or it would.

       You'll probably have 1 engine in your entire chain due to inefficiencies. And I agree with Bungston, even though he's bitter about his body bank.

       What if the heat from the lamp only goes to the first engine. The other engines would be insulated from its heat and powered only by the heating coil from the preceding engine.

       Actually changed my perspective on this idea, and my vote+

       Sitting at your computer watching the 5 or 6 engines spining with the orange glow of the heating coils. All that simply by turning on your desk light.
