Entry # 35 can you make the rectangle shapes maybe have small octagons inside to resemble a solar cell and give the wave more wave look since this can be associated to a paint brush swirl but I like the idea you are running with. Thanks for your submission and I look forward to others you may have.
Entry # 40 is more on target than the others. The wave sort of looks like the Nike symbol so let me know if you have other suggestions with the wave. Also what do you think about incorporating some sun element into the logo?
