The BMW Gina’s defining characteristic is its spandex like textile skin that replaces a metal outer body. The textile skin fits over an aluminum and carbon fiber wire frame. This means that when doors and trunks open and close, they flex instead of swinging on hinges.

This also means that if the skin were torn, pierced or punctured or damaged in some other way, it would take only ½ an hour to replace the entire textile skin of the BMW Gina. Conceivably this would be a bit safer for pedestrians and bicycle riders that may collide with the textile.

But, the most important feature from a green standpoint is that this reduces weight in the vehicle which equates to great gas mileage. Replacing metal with fabric is one way the car manufacturers can increase MPG’s in the future.

Will the BMW Gina ever be a production vehicle? Probably not, as there would be a whole host of crash test issues to overcome. But, it does give us a peak into the future and another idea of how to increase mileage, reduce emissions and increase energy independence.

In order to qualify for the top 6, the finalists had to do 3 things:

1. Show the potential of the product (or process) to reduce greenhouse gases with a rough estimate of its impact.
2. The product should be far enough along to execute in front of the judges.
3. The product should be ready to bring to market within 2 years

The finalist also has to commit to bring the product to market themselves if need be or commit to working with organizations who can do this. In addition, the finalist has to show up in Amsterdam and present their idea to the jury in order to claim their prize.

Here’s a rundown of the finalists:

Sanne Castro wants to develop a biogas system to provide energy to millions of people in developing nations.

Dean Gregory wants to develop low cost rooftop wind turbines that work in low wind conditions.

Michael Mathres has developed a feed extract that reduces carbon emissions from cow waste.

Robert Mathams coordinates individuals and transport providers making best use of overcapacity.

Hjalmar van Raemdonck developed an aerodynamic solution for trucks to reduce fuel consumption and noise.

Robin Chase is introducing innovation and flexibility to future and present rolling stock of vehicles.

More will be known about each product and process in the weeks to follow. Details are purposefully sketchy right now as to not tip one’s competitors too soon. And, unlike some TV competitions, no one gets voted off the island. In fact, the island will be a little greener because of each contribution.
