Hi, could you tell us the reasoning behind these samples? are these the styles you like?
Do you have a current logo that you'd like to add an icon to? My interpretation of the brief is you simply would like to have a stand alone icon that can be added to your business name (ie we do not need to design the name). If this is an accurate interpretation, it would be good to provide us with the file copy of your existing logo so we can create an icon that works with it. Thanks!

We do not have a logo yet. The images provided were the result of a brainstorming session in which a bunch of engineers tried to design a clever logo (not a good idea). We would like to have a logo in which an icon is integrated into our name as an element, such as the curl of the wave replacing the "C" in our name. Our product allows the data center engineers to "ride out the wave" of the energy demand, so a logo/element that show a gentle ebb and flow is ideal. Also, of interest is that the middle part of our name contains the letters "DC" together which is also the fundamental difference (DC power) in our solution.
