Very interesting, I had not thought about using rocks for thermal storage. Nice idea about recycling old fans to route the air through your system.One small correction: you suggest using an inverter to power the fan(s). An inverter takes direct current (DC - usually 12V, or something that can be easily stored by batteries) and converts that into alternating current (AC - usually 110-120V, or what normally comes out of your wall outlet.) Your description shows using a 120V to 12V device, that is almost always 120V AC input and 12V DC output; this is called a power supply, rather than an inverter. Other than that, this looks pretty good.
