I remember hearing about the DeLorean car production on UTV and BBC Northern Ireland when I was about 14 years old. With the Troubles, the DeLorean factory was about the only thing positive on the local news. My family had returned to N. Ireland from the US in 1979. I got to see my first DeLorean on a bus journey from Derry to Belfast as we passed over the Glenshane Pass. It was unlike any car I had ever seen in person, low to the ground, unpainted, and sporty. I knew that someday I would have one.

Some 25 years later and living in Houston TX, my work involves looking at investments in emerging energy technologies. One of those technologies indirectly involved Li-Ion batteries. The local battery expert introduced me to the potential for electric cars. The motor and energy characteristics were intriguing. What was clear was that I had a lot to learn. While I was a professional programmer for many years, and I had worked on cars for many years, I had very little understanding of the electrical and engineering issues involved in building an electric car.

In 2011 I decided I wanted to convert a car to electric drive. I read a few books and consumed as much online guidance as I could. I needed two things... 1. a much better understanding of electric car systems and 2. a project car. Then I found the videos of the electric DeLorean by Dr. Delman. That was it. I bought my DeLorean in 2012 from a seller in California. The car was in great condition, but was still 30 years old.

My plan was always to get the DeLorean running well, restore all the stock systems, and then in time replace the engine with an electric motor. Then Tesla happened, and the TesLorean was born. I had no idea how to do it, but I knew it was going to take some years to design and build, and I am still right.

These days I work as an internal company consultant, spending my weekends on TesLorean or house related projects. I've learned more about electric drive, fabrication, control systems than I could ever have imagined. It has been a fascinating journey.
