These links are to pictures of what our primary product looks like and how it functions.
I would like to see some concepts integrating the Golden Section, Pi, a Nautilus (represents the Golden Section), a sunflower (the seed pattern represents the Fibonacci sequence) or other universal natural concepts of beauty.
One idea I had was the Parthenon, which integrates the Golden Section, a roof line (representing the installation location of our product) and the columns represent the evacuated tube collector.
The above is only one idea, and other ideas could include references to the sun, water, heat, energy, and motion.
We very much like the MMK Solar Thermal logo, the colors are nice, and the yin/yang concept is fantastic. Unfortunately, this idea has been taken already!
