This is a larger Stirling engine that has a 12v DC Permanent Magnet motor operating fixed as the flywheel bearing. It produces 15 Volt max with NO LOAD. This setup as is produces about 15 watts. The heat sink is a water cooled tank that is a bit short for the displacement piston but does work. I will be adding some heat sinks soon and testing it with the 56 inch dish and a Fresnel Lens. The motor/generator has an additional pulley that the other engine I have may be tied to. The water can be fed continuously or as a tank.

How big a setup would be needed to power a typical home? I ask because things like this fascinate me and I wonder how far off we are from being able to take an average house "off grid" using solar sources.

do you have one "powered by" a fresnel lens?

Won't try putting in a large stepper motor. Didnt you say they are more power wise better as a generator.

@pmryan25 Look up Molten salt storage
A variety of fluids have been tested to transport the sun's heat, including water, air, oil, and sodium, but molten salt was selected as best. Molten salt is used in solar power tower systems because it is liquid at atmosphere pressure, it provides an efficient, low-cost medium in which to store thermal energy, its operating temperatures are compatible with today's high-pressure and high-temperature steam turbines, and it is non-flammable and nontoxic.

@bhitt99
(39.37"x2π)/4 = 61.8" (area of mirror)
(2"x2π)/4 = 3.14" (area of focal point)
61.8"/3.14 = 19.68 (magnification)
1 meter = 1kw, that's 3412BTU/h directed to a 2" surface. Variables (clouds, trees.) will alter that number.
Converting to °F is a huge variable, there's no way he could give you a temp that would be optimal for every Stirling engine. If the surface temp of the road is 108°F on a sunny day, then a magnification of 19.68 will bring the 2" focal temp to 2125.44°F
