When we were brainstorming ideas for Earth Day posts, we thought about featuring the ten most exciting green cars we wish we could buy today. It turns out that there are at least twice as many green rides on the horizon that we'd really like to have today, so the list has expanded. We'd like to note that this list is far from complete; the green sector of the automotive industry is growing in leaps and bounds. Start here and join us for a guided preview of our future garages or jump ahead by clicking on a number below. Either way, enjoy!

Want to know the hottest, green trend in car design and the vehicles that are sure to turn heads in 2008? The answer, IMHO, is convertible, two door, mini SUV/crossovers. I have compiled a list of the top 10 best concept Jeeps and Jeep-like vehicles for you. Why will young, hip, urban types suddenly go Daisy Duke and start driving a Jeep? Small vehicles like sip gas when compared to an SUV and with gas prices probably going to $4 a gallon next year, a vehicle type even smaller than the crossover that maintains the usability and apparent safety of the SUV just might take off.

Major car makers like GM see green technology like hybrids and smaller design as a way to improve the mileage and sales of their best selling SUV. Crossovers as a solution to the problem of slowing SUV sales are losing steam and, as 2007 comes to a close, we are already seeing a Hummer even smaller than the 20 MPG H3 and the BMW Mini entering the SUV market. The Hummer and Mini SUV are on the top of our top 10, which you can read in full below the fold. Are you ready for modern, small off-roader?

Mobile homes, RVs, travel trailers, caravans, and campers are very green forms of housing because they are prefabricated and small. Mobile homes' assembly line construction uses less energy and creates less waste than regular home construction. Mobile homes are usually smaller and that means less energy to heat and cool. We figures there are many new modern designs for mobile homes you might have missed, so we compiled a list of the newest and the best in homes on wheels. Below the fold are the 10 best modern travel trailers, RV, campers, caravans, and mobile homes. No one will mistake you for an old couple taking a cross country trip in any of these designs.

Lighter-than-air vehicles don't get enough credit as a form of transport. Okay, there was that one little crash and they are not fast or easy to control. If you get past the safety, speed and control issues, though, they are a great form of transport. Lighter-than-air vehicles are efficient, silent and, in their own way, beautiful. Below the fold are the top 10 most interesting lighter-than-air vehicle videos we could find. Enjoy.

Modern Mechanix is a really great magazine that began in 1928. It's a lot like Popular Mechanics and Popular Science but focused on the efforts of do-it-yourselfers. There are lots of ideas we may think are new like compressed air cars and small cars but were chronicled in the pages of this magazine. Looking through the archives, it became clear how much cool stuff has been around for a long time. Below the fold you will find our picks for the top 10 articles about green automotive inventions.
