Rob from cockeyed.com build himself quite the solar death ray using a satellite dish and mirrors. He probably could have roasted the heck out of a chicken. Check it out: http://www.cockeyed.com/incredible/solardish/dish01.shtml

"From a technical viewpoint, I thought if you changed gender from female to male that you kinda got the whole package, penis and testicles. Did this guy not get that? If not, how is he a man? Flat chest + testosterone pills = male?"

Apparently, most transmen (correct me if that's not the proper term) only get the top done, since phalloplasties (having penis made) doesn't work that well. They don't look very good, and don't have much sensation. So most transmen skip it. I guess many of them have hysterectomies and have their ovaries removed, but not all, and clearly Thomas kept his. So from the waist down, he probably look like a normal, if hairy, woman.

As for what makes him a man, one can have one's gender changed on one's birth certificate is almost every state. So feeling strongly that he is a man and then having his legal identity changed to reflect the gender he identifies as is what makes him a man.
