You might be interested to know Stirling Energy has created a 25kW version that uses a 38 foot dish and a 4-95 (4 95cc cylinders) stirling engine - it even tracks the sun.

Could this Stirling demo engine be made more efficient if some of the flywheel energy was used to drive a fan over the cooling fins to increase the temperature differential inside the engine? And can some of the extracted heat from the cooling end be recycled and fed back to the heated end?

Likely inventing alternative energy is just the easy part.Beating the mother off all interest called the oil industry(that pretty much owns the military-industrial-media -intelligence complex)to systematically integrate it is the hard part.
Would be “slightly” naive to assume they’d simply say bye bye to their trillion dollar industry not?

I discuss the working of the stirling engine on my site, feel free to take a look and point out any mistakes

Those always make me smile. I made one cheaply out of tin cans and put it on my channel. Enjoy!

the $64,001 question is.. can you transform that motion into electric and store it, and if so can you can you get more energy that way than using solar panels alone?

Something like this would be good for recharging solar batteries after a few days of no sun.

yes, if you can get a city-block sized lens to focus light on to the hot region of the engine. it only worked without the lens for that long because the focused light heated the engine up to an incredible temperature. if you want the engine to run through few days of no sun, not only need a huge lens, you also need some sort of system where you can take the hot region off and store it in a thermo so it can be used later on

i doubt it. if you cool the engine by rotating a fan, that fan is exerting a resistance to the engine’s motion. what you can do, however, is have heat-pipes to a water supply (preferably running, like stream or river) and cool the “cold” side of the engine. and heat-recycling would be extremely hard. the hottest part is where the heat is applied, and heat only moves away from there, unless u got a heat pump, which still will make it less efficient
