The Science of stargate

I any of u catch the special about aloyt of the things in stargate are actually possible i wanted to here your take on the matter.

Theres a lot of good ideas in it but still Sci Fi unless they put billions into something. Cars without oil based fuel is also possible since 20 years but the oil companys who have shares in the car companys wont allow this of course

Theres a book called "The Stargate conspiracy" havn´t read it yet but should be interesting.
