The Engineer

David Warren Lee
Chairman, Project Director, and Systems Engineer
Society For Sustainable Mobility
Malibu, California

David Warren, 30, works as an engineering product manager for a defense contractor by day, but in his free time leads the Society for Sustainable Mobility's Open Source Green Vehicle Project. The goal is a seven-passenger SUV that will get 100 mpg, sell for about $30,000, and, he says, have the performance of a Porsche Cayenne.

"The car is called the Kernel, because we're using the same idea as Linux. So far, I have 150 engineers helping -- all of them are part time. We provide the essential functions, plus interfaces so things can be plugged in. The power-source module could be battery or gasoline or compressed natural gas. If you wanted to go from gas to diesel, for example, you could swap those modules in a couple of hours.

I'm working on the electrical architecture, the basic propulsion system, and the power management. The chassis and suspension are being designed at Rotterdam University, and they're going to be made out of a polymer. With steel, extracting and shaping generates a lot of greenhouse gases. Plastic takes a lot less energy to produce."

The Student Teacher

Nii Armar
Codirector, Vehicle Design Summit
MIT
Cambridge, Massachusetts

Nii Armar, 23, is an MIT aerospace engineering graduate student who, along with undergrads Robyn Allen and Anna Jaffe and 2007 grad Jonathan Krones, runs an international open-source project of students trying to build a 200-mpg car.

"Anna and Robyn had the original idea: They went to the 2005 World Solar Challenge, where teams build cars to cross Australia, and saw 40 very similar vehicles. They thought, Maybe we could get these people together to collaborate. Vehicle Design Summit 1.0 brought 50 people to MIT in 2006.

We decided to make the 2007 summit virtual, collaborating with people from schools around the world. The goal is to make a low-cost, 200-mpg four-seater for the Indian market. It's a plug-in hybrid, and we have about 200 people involved, almost all of them students. We're aiming to have our first iteration done by the end of summer 2008, then a final version by 2009 or 2010."

The Design Pro

Geert-Jan Schellekens
Principal Automotive And Industrial Designer
SABIC Innovative Plastics
Bergen Op Zoom, The Netherlands

Geert-Jan Schellekens, 45, is the principal automotive and industrial designer at SABIC Innovative Plastics (formerly GE Plastics), where he works on the C,mm,n (pronounced "common"), an open-source car project managed by three technical universities in the Netherlands.

"We help our customers develop the end product, whether it's an MP3 player or a car. So being involved in design of this kind is not unusual. With C,mm,n, the chassis will be metal because it does the job better: It has very high stiffness. But the body will be plastic. It's lightweight, and it gives designers the freedom to make a vehicle that's more aerodynamic so it's more fuel-efficient. As a company, we do projects like this to stay in sync with what's going on in the world, and the whole idea of open-source design is very interesting. It's like the automotive Wikipedia. We've learned a lot."
