Tesla

Tesla is the surname of the famous inventor, Nikola Tesla. The Tesla coil is one of his inventions, and his name has been used as a unit of magnetic flux density. 2244 Tesla is an asteroid that also bears his name. Tesla Motors is an electric car company based in California. 

The agents of Warehouse 13 use an energy weapon called a Tesla. 

I think that his name lends itself well for girls, since it ends in a, and can lead to the nickname Tess. My only concern in using this name is if Tesla Motors becomes popular in the future, it might be like naming your daughter Honda. Otherwise, it's a great way to honor the brilliant scientist. In 2011, 70 girls were named Tesla, as well as 9 boys.
