I have am researching using hydrogen to help with fuel economy and trying to figure out if it really works. The site I have looked at the most is water4gas.com. I am getting 15 mpg on my Tahoe and trying to find something that will improve the mpg. Can you please help? Thank You

Dear Don, Here is an answer from Brandy. She is an editor for Ask Patty. Dear Don, I'm sorry, but I know very little about these products that you can install to use hydrogen boosters to your existing engine, but I'll do a little more research to post a future story at askpatty.com. In the meantime, I can tell you that I am a huge fan of the current round of real-life concept vehicles being produced by manufacturers to run using a complete hydrogen powertrain. Hydrogen is a clean-burning fuel, offers equivalent fuel economy to gas, and can be refilled in minutes at special hydrogen stations, instead of the hours required by battery-powered vehicles. Such hydrogen fuel cell vehicles are being produced by Volkswagen, Honda, and Chevrolet. Chevrolet is currently promoting a program called "Project Driveway" in which they are placing a hundred hydrogen fuel cell powered Chevy Equinox SUVs into the hands of consumers and select notable public features. The program is meant to raise awareness of hydrogen as a viable vehicle fuel source, and also to gain valuable real-world information about the performance of these vehicles. More info on the program is here: http://www.chevrolet.com/fuelcell/ Depending on where you live, you might be able to become one of the drivers of these vehicles. You can find out much more about these cars and the program at the following link: http://www.greencar.com/features/vision-award/ You can find out more about how hydrogen works here: http://www.greencar.com/features/hydrogen-fuel-cells/ In the meantime, you can get more hydrogen-related information at the following links: http://www.askpatty.com/page.php?ID=1654&t=Volkswagen_Debuts_Zero-Emission_Hydrogen_Tiguan_HyMotion Volkswagen Debuts Zero-Emission Hydrogen ...
