Reminds me of the first electric car i built. Worked great... for 11 miles. Then it needed to charge for 12 hours. I thought I was sooo smart, but it cost me a ton of money (well.. $2300, and at 16 that was a lot) and I couldn't even drive it to school.
Just because you missed a few key parts, doesn't mean you're stupid. Don't let them get you down, you've obviously grasped the basics of hydrogen fuel in a few short days. Give it some time, and you might figure it out.
Oh well, "if at first you don't succeed, get a bigger hammer!"
Also... If you want to be taken seriously, don't scream any time someone questions your idea. And.. Show some damn proof! I can claim that I made an airplane that runs off used breast implants. Until I show proof, everyone is going to call me stupid. Just my 2 cents.
