Oil retains most of its heat through the night. The stirling engine runs on the temperature difference between two locations on the engine, enough to mechanically or electrically power a dehumidifier, air conditioner, or even a power generator. Stirling engines are very scalable, yet even one a few inches tall can run off the heat of your hand. With a fresnel lens heating up your oil to just below smoking temperature, you could have a few stirling engines running in tandem, or one for each device. Coupled with geothermal heat exchange, you could ditch the oil and just use the temperature difference between groundwater and the air, and 21 feet in the ground, the temperature there remains constant all year round, equal to the average temperature of the air at ground level. All sustainable energy comes from the sun anyway, might as well be efficient... That stirling engine can cost you a lot of money. You'll likely want to find plans online and make it yourself. Geothermal is good for air conditioning, 1/4 the running costs of a standard a/c according to my parents who have this in their home in gulf coast alabama, but I don't know if it has enough power for generating power, unless you know or learn how to eliminate lenz law magnetic drag, which has been done in several ways. As you can guess, it requires rewiring your generator's coils, a nightmare if you don't know what you're doing, but it more than doubles the energy output or requires half the input power by reducing induced magnetic eddy current drag to zero.
