Physics Questions? Ask the Van

Question of the Day

"My question is involving water and electrolysis. Everything I have found says it is possible to run an internal combustion engine on hydrogen but that it would take a large storage tank to do so. What I ask is what if instead an onboard eletrolysis tank was on the vehicle. The water wouldnt evaporate as rapidly so it would store the energy but would it be enough energy to power the vehicle if say you had 20 gallons of water? I know it can be utilized as an aid by that method according to an American Cycle issue where a motorcycle with a turbo charger and a small electrolysis tank cut gasoline usage by 50%. I just want to go for the full 100. My email is ### Thank you for any info you can provide. I sure appreciate it."

About Us

7934 questions have been answered online since 1998 by volunteers from the Department of Physics at the University of Illinois' Physics Van outreach program. We've tried hard to make this the most reliable physics Q&A site on the Web, but no site is perfect, as we explain on this note. Our Baloney feature provides examples of how shaky many other sites are.

If you'd like to ask us a new question, not already covered, please read our answering guidelines first. We try to answer as many questions as we can, but it's not always possible to answer them all. Questions from kids are especially welcome.

Although we recommend not using our informal site as a cited reference, students who are in a rush and can't find a more proper peer-reviewed source can check our citation information section.
