Help with some research please?

Hi guys.
IM doing a "Themes exploration" project on Dracula for my A-levels.
Ive chosen to look into how the "Theme" Of technology is used in the book. Ie like the typewriter Mina uses or whatever.
So far ive basically got that most of the technology in the book is used for communication.
I was wondering if any of you lot could think of any other ways in which the theme relates to Dracula?
Much appreciated :)

You could look at the transport and how communications was transmitted/sent of the time. At the time it was written this may have been quite modern to the period. From what I remember there were boats and coaches. Photography, a vampire can not have its picture taken because of being without a soul.
