TdS Report #12: Team Profile: DC Cruiser

Mark and Seth Murray are the father-son team that built the "DC Cruiser". Seth
told me, "We started about two years ago but didn't really seriously start
working on it until 6 months ago. Our first test drive was April 7th. We've
got about 1200 miles on so far; not bad for 5 weeks." The Chevy S-10 is a
popular first conversion platform, especially if you talk with Bob Batson of
Electric Vehicles of America. "He is totally right - it is the way to go."
The truck was $350 with a blown engine but a good body and frame. Seth paid
for about 1/3 of the project; the rest came from various family members.

driving very conservatively." He drives the car about 30 miles to his school,
charges there and then drives home. "They gave me my own parking spot with an

Seth is already planning his next project. He would keep the clutch and get a
better, solid-state charger.

This is not the first father-son project. "When I was in 5th grade we built a
small electric go-cart out of bike parts, plywood, angle-iron and a little
winch motor. The greatest day was when I drove it down the hall and into the
classroom to give a presentation."

What is Mark's part in all this? "My dad is very handy. He builds boats for a
living." They wanted to show that a father and son could build an electric
vehicle that can be used every day.
