Hi. I really, really dig these designs. At the moment we're looking for something more representative of green technologies, such as wind energy/solar power/biofuel and so on. Think you could come up with something like it, in the style of #13 or #14?
Thanx for the feedback, i think this design can be reproduced to make varied things, like wind energy, solar energy and biofuel etc. i have made separate icons and combined them also ina logo to show you how they will look, all made from single icon 1. Solar energy
