Technofantasy
Technofantasy is a subgenre of fantasy, which has some elements of science and technology but it does not rationalize their use through scientific or quasi-scientific terms, which distinguishes it from science fiction and science fantasy. The less realistic and the more "technobabble" any explanation is, the closer the work is to technofantasy. The concept of technofantasy has been described as "destroying the difference between magic and science". See also
