You are going to have to look at real houses and scale them down. The model is going to have to be huge enough to have space for the items to fit and show how they work. That means space for a photocell panel on the roof, windows on a wall for solar heating of a floor of plaster or stone that can pretend to be cement, and space for a battery and a small lightbulb and fan. With proper design you can use incense smoke to show circulation of warm air without the fan. You will need a white heat lamp (not red) to be the sun.

Yes, it will work, but not as good as an actual three bladed turbine/ propeller.

This review is from: VDC Electronics BatteryMINDer 12 Volt Solar Charging System with 5 Watt Panel and Desulfator, Model# SCC005 (Misc.) The solar panel arrived in good condition and worked just fine as soon as I connected the wires. I set it up on a work bench to test it out and it has worked very well. The rested battery had 12.46 volts showing and began to rise right away. I have not been able to do a sunny day test because it has been overcast and raining everyday. If there is decent light out the solar panel can do it’s thing and that is just what I want. I will have to wait to give a superior sunny day report, but for now all is well. Sorry for the lack of sunny day detail. I plan to use the charger on my travel trailer to keep the battery up. I did try plugging in a power inverter to see if it would work with one attached to the battery while charging and it worked as well. Satisfied with the purchase. Would I advocate it: yes Con: the delivery time was a bit long I thought, compared to other buys – but Amazon has spoiled me with other swift deliveries.
