actually I'd argue that the Time Machine and WotW are, as well as the birth of Science Fiction in general, where the Victorian SF (steampunk) meme started as well.

the idea that we started to reverse engineered Martian tech is mentioned in WotW and you can't get more out there than the Time Machine.. specially the 2002 Brass, Glass and Wood beauty....

 

"By extension, any contemporary SF written now will be called Early 21st Century Techpunk.  See?  Silly, ain't it?"

well. you know there's Cyberpunk, Dieselpunk.....
