History of the Car

Reassembled from Umass Lowell’s donated solar car parts, the Nerdgirls’ car, “Anne E. B.,” was reborn summer 2002. In her previous life she raced for Umass Lowell. Her accomplishments include:

  • Sunrayce 93 - Dallas to Minneapolis, 8th Place
  • Sunrayce 93 - Teamwork Award, 1st Place
  • Sunrayce 93 - SAE Engineering Excellence Award
  • American Tour de Sol 95 - 1st Place Solar Cross Continental Category
  • American Tour de Sol 95 - Most Efficient Solar Cross Continental Category

Naming Anne E. B.

Anne, daughter of Betty and Roger Borghesani, graduated from Lexington High School and Tufts University. In March 1990, Anne was brutally murdered by a stranger as she walked from her apartment to the Metro in Arlington, Virginia. She was planning to meet friends to celebrate her twenty-third birthday.
People and community were important to Anne. She was a family person, an upholder of traditions, a loyal friend, a great communicator, and a person who brought people together from different religions and cultures.

The Nerd Girls feel that Anne encompasses the spirit of the project bringing the team together to work towards a common goal. Betty and Roger believe that Anne would have heartily endorsed the project's goals of promoting women in engineering, along with teamwork, and renewable energy. Although math and engineering subjects were definitely not Anne's areas of strength, she was certainly a supporter of women's abilities to succeed in all areas of study.

The Nerd Girls thank the Borghesani family for their permission for using Anne's name.
