Think! Biofuels Group, LLCLogo Design Contest

Mazive: Thanks so much for your fast entries!
#'s 1, 3, and 5 were too hard to read.
I like #4, but it's ultra colorful. And the "Biofuels Group, LLC" is hard to see. It looks like the company is called "Think!"
The drop of biodiesel was a nice touch.

#14 is getting closer

We are starting to get really interesting here.
I think the use of color has been too much, and I would like to see darker attempts please.
Also, I don't know if this would work but what about a design where the company name is positioned like:
Think
Biofuels
Group
And the Dot in the "I" in THINK is the spout of the gas pump, the vertical line in the "I" in THINK is the start of a droplet, and the "O's" in BIOFUELS and GROUP are droplets (narrow droplets).
Would that look wierd?

Now we are getting some really great work!
I have re-ranked them, as you can see.
I have decided that we should NOT use the slogan any more. It's just too small and hard to read. This has to work on business cards, and really small type is impossible

I wouldn't mind also seeing some totally different designs, just to see what other designers can come up with. Just read my comments from before, and give it a shot!
Thanks

When creating our logo, please make it:
1) describable
2) memorable
3) effective WITHOUT color
4) scalable (i.e. works when just an inch in size)
5) appropriate

Don't be afraid to use shape, and negative space.
You can use action, like the movement of a falling droplet, or the forward momentum of a vehicle.
Biodiesel is made from Triglicerides (fat) with the glycerin removed. Perhaps you can do something with that. Really GO FOR IT!!!

In a word: Wow! Great work so far everyone.
Comments:
I realize now that I should have asked for a MUSCULAR and MASCULINE logo. That means no cutesy or clever stuff, no flowers! think Mack truck leading, with a Prius behind.
Please convey the POWER of fuel and power of thought.
#4 has one of the most effective images, the green leaf. It is not power packed and the rest of the design doesn’t hold up, but the image by itself is memorable, appealing, even beautiful. But as a stand alone item, it can’t carry much weight.
#14 and #22 has what strikes me as a better image, more colorful, and the color has meaning. The typeface and arrangement are weaker than #14, but possibly the image could be transposed to the other format.
#35 caught my eye at first, but doesn’t hold up to the principles above, but it has one item that works, the sun used as the dot over the letter i. The sun image itself is wobbly and could be much stronger, especially given the fact that the sun is an enormous power source. Now look at #46, where the same dot idea becomes totally believable in form.
Now go to #55. Here is a logo that is starting to get a lot right. The lettering is compact, powerful, sleek, a perfect, effortless rectangle and that green line gives the message without a lot of gesturing about. The colors are wonderful, the black is the black sedan, the black tie, the “knockout” color, and the white lettering suggests clean, pristine. The light bulb is another of those Too Much Information devices….got to go. It all has to be centered on the sheet.
#58 is the most effective of the new ones, and one of the best over all. I like it better than #14 or #22. It plays a clever little mind game with the different shades of gray, which kind of catches up with you for a second hit, oh! They made me think! The wave effect is very subtle and here suggests movement, energy, whereas in #14 that doesn’t come across.

Hello, kindly accept my entry in the contest, hope to see some feedback from your side. thanks & take care.
