Great informative show Doc!
You wouldn't by chance have a PDF of that Hydrogen fuel cell you made would you?
I'd like to see some more detail on how you put it together and try one myself.
Also, running that vacuum hose from the intake to the fuel cell like you did, with the top of the container drilled out, does that cause any problems with how the car runs?
I ask, because that looks like it might have the same effect as a big vacuum leak.
