We've been stockpiling your comments and questions for a couple months... Alternative Hydrogen Generation. Potato Guns. You need a load to measure current. Building a Radar Jammer...

Before I even download it, is this episode even worth the bandwidth?

I believe you need 2 disparate metals (like copper and zinc) to properly make a lemon battery work...

If you are using the same metal at both the anode and cathode (you used nails) of the battery/salt bridge(in this case the lemon) the only thing that is providing the current is the concentration gradient of ions in the lemon itself. This leads to completely unpredictable voltages across a given lemon. In a normal battery it is the two different materials used at the anode and cathode that produce the majority of the voltage. this (http://en.wikipedia.org/wiki/Table_of_standard_electrode_potentials) is a list of the electrode potential of different materials. Materials near the top make good anodes(-) and materials near the bottom make good cathodes(+) the farther two materials are apart on this scale the larger the voltage you will achieve. If you want to make a lemon battery with a decent voltage difference(enough to charge portable electronics) using different materials at the poles is the only reliable way.

Randolph, Norton, what the heck!?!?! You guys take the week off? Seriously?

here is a link to the guy that "the man" did "keep down" after he built a hydrogen fueled car. Google his name and you will see he mysteriously died from an aneurism from poisoning, just saying.

Could you pleeease change your power saving option on your laptop? It's really annoying when you have to move the mouse every minute to get it to light back up...
Great show. Keep goin'!

I kinda feel like you guys didn't really address what most people are upset about, which is ~9 minute long shows where you don't show any work you just sort of pop out the end results ala Food Network.
I'm not sure if you guys don't get it or just can't get it to work, but you know that 72 hours you were talking about? I know I for one would have liked to see at least 15 minutes of that. And if you think something is important enough to talk about on the show, why not demonstrate it for us?
I love this show and it has so much potential, especially with two great hosts such as yourselves, I would just really like more content. I had no intention of building a mame cabinent, but I was still excited to see yours and I was really hoping to actually see it in action, although I can understand if that was a legal concern, it's just that 5 weeks of build up with absolutely no action shots of the end result was a downer.
