My research was on the environmental part, not the mpg of the cars. I was more commenting on that most car manufactures ship parts around the world and back throughout the process of making a car.^^^what research have you come up with actual MPG of a Prius. My friend rented a Prius to drive from Los Angeles to San Francisco a few weeks ago, and found out that while the Prius is rated for some 60 MPG highway it only ranged in the low 30's MPG. When he called the rental car agency to see what's up they stated that that's the norm for the Hybrids. They don't get the MPG that they are rated for. It was a funny story cause he rented the Prius for the gas, but gets better mileage in his xB. He has made it to S.F. from L.A. on just over one tank many times averaging out to 36-38 MPG. Prius at best was 30-33 MPG.
The basic method to making hydrogen fuel is:I donlt know about the Hydrogen cars. great they emit water as a by-product, but then we'll drown in our own by-product. the earth's atmoshpere will over hydrate.
