Corporate logo for Green Technology company

Transitional Technologies, LLC (no website yet)

We are a fast growing Eco friendly company focusing on the Transitional Technologies needed to take us from present energy sources into the next era of energy production. We currently build and sell hydrogen generators around the world for the auto industry (http://www.hhokitsdirect.com) and teach others how to build them (http://www.hybridwaterpower.com). We are also expanding our line with the next generation of home power savers (reduce electric bills by 20%-30% a month) and are working on developing water treatment products, gas vaporization units and hydrogen assisted generators for commercial use, as well as new electrical motor designs and HV plasma research.

We need a logo to cover and portray this scope (not just auto industry) of transitional technologies that will help us convert from old school energy to new technologies. We can't throw away 200 million cars- or knock down all existing homes- which would be wasteful. We believe developing transitional technologies is the next wave of practical breakthroughs.

The auto products target largely mechanically inclined males in the 30-60 age group, although we have guys in their 70's who are buying our systems.
The other technologies target a much larger demographic.

Must have a good logo that portrays our company goals in a professional looking way that would be good enough for a professional business card, but not so stuffy that it couldn't be handed out to a person who would like to buy and install a system in their home or car.

May or may not incorporate the company name in the logo- Transitional Technologies, LLC

Open to color schemes, prefer deep greens and blues but open to creative concepts

Rather not have a picture of the earth- seems everyone is doing that, but if your design is decent, will still consider the option.

Logo design should be in Adobe Photoshop or Illustrator format
