That would be Mars. This Amazon reviewer helps us out:
John Rolf is an exiled human, living midway up a spiritually-significant Martian mountain and, for vague reasons, developing a telepathy machine. The machine brings the attention of corporate raiders (seriously) from Earth, who bring along his daughter as thinly-veiled sex hostage.
The i-machine helps develop telepathy,and from the looks of it does something awful to your hair and cheekbones as well. Unless that's just what the readers expected when it came to Future People with great mental powers. They wouldn't be fat with a comb-over.
Too bad the tagline on the top didn't end with "Walk into a bar."
