Finally! A working mini solar tower powered by a fresnel lens that turns a turbine, a paper turbine. It's nowhere near powerful enough to turn a PC fan. This one is built like a screen/matrix solar air heater and isn't much like a solar tower like the 5 previous versions. I'm using my fresnel lens and mirror solar cooker setup for the structure.

Watch my "Where I use Math" video to see the chimney formula I used for this project:

Version 7 was the final version and was able to turn a paper turbine and got a boost from an actual tower, but did not generate electricity.

For the version 7 of my solar tower, see:
