Logo for a ecological friendly mobility exhibition/fair

What we need is a hip logo which has 2 important qualities:
It has to have something to do with ecological/environment friendly mobility. Mobility in this matter is very diverse (cars, boats, scooters, segway's, Vans etc.)

And it has to be an eyecatcher. not to much, but a good combination of a business logo and a hip logo.

eco mobiel

We are a company that is organizing a congress and exhibition/fair which focuses on sustainable and ecological friendly mobility. (In the Netherlands)
The companies that will display their products on the exhibition are producers of all types of ecological friendly mobility. Such as cars, boats, transport (electric vans), Segway's etc.
Other companies that will be present on this exhibition are car lease companies that particularly focus on ecological friendly cars, companies that produce hybrid or electrical motor systems and on top of that producers of motors that are driven by water or air pressure.
As you can read the products will be very diverse but all with a ecological friendly character.

Designers are free to go their own way and give all kinds of input!

As long as it's has the 2 qualities as discribed in the summary.  

* The logo will be used for all the exposure of the exhibition/company so it will be on:

- The website

- The promotion material

- Correspondence with customers

- Business cards

- Company paper

- business proposals

- etc. etc.

So it has to be a logo which can be used for all of the above matters.

Furthermore whe are a dutch company and the exhibition is in the Netherlands. The name of the exhibition/fair is "eco mobiel"

Name doensn't HAVE to be in the logo itself, but it's possible, whe leave that up to the designers. We do need the name designed, but the letters can be separated from the logo.

Your free to try some things out!

Not particulary,

as long as it has the qualities as descriped.

If you have more questions please feel free to ask!
