That was both funny and informative. Don't know how much power they were actually making, but hey, it was donuts, vodka and tea.

Submitter here. The guy in the video is a friend of mine in the lab.

That particular cell is making about 40 microamps in the video. I don't know the area of illumination, but I'd guess it's around 2-3 square centimeters. It's certainly not the next generation of solar cells (though we're working on that as well), but it's a fun thing that you actually could do in your home.

Spectacular.

Bravo science!

How much wattage would 12 drunken cops connected in series produce?

Still, that's pretty good for easily found (if not consumed) items.

However, I have a question for you. You found a good use for anthrocyanins, but what has yet to be addressed is are you REALLY a super wombat man? And if so, do you have an arch nemesis?

My mom tells me I'm pretty super, so I'm gonna have to go with yes on your first question. As for my arch nemesis...it's probably the Mad Advisor. Seems to be able to sap all my power whenever he's around.

Very awesome... I'll have to steal some ethanol from lab to try it out

Does anyone else immediately get a crazy, unstoppable high when they eat a powdered mini donut?

Now I'm wondering if old LCD displays would make a good source of conductive glass, thereby making the whole thing a "found items" project.
 
2009-03-17 06:23:53 PM
about 0.002 Amps / square meter (please check my math)? How many volts?

You've got the cheap (compared to tradition mono or polycrystaline cells) but the efficiency...

Anyway, that was a fun, informative and cool video! Thanks.

maxheck: Now I'm wondering if old LCD displays would make a good source of conductive glass

Good idea, I was thinking that the conductive glass is the only component which would put this project outside the ability of most people to try.

Actually just found a page(^) on how to make your own conductive glass. It looks pretty easy but maybe not something you'd want to try in your apartment kitchen.

I actually get about 0.13 A/m^2 (40 microA * 10^(-6) * 100^2 cm^2 / 3 cm^2). As for the voltage, I have no idea. I don't think that's really been tested. If I had to guess, I'd put the open circuit voltage (i.e., no current being drawn off) at maybe a few hundred mV (negative).

Yeah, the conductive glass is probably the hardest thing to get, although I would think that you could put some aluminum foil or something in there around the edges that would allow for conductivity (do this before dropcasting the TiO2, obviously) with regular glass.

Your performance would probably suffer some due to increased recombination losses, but it should still work, I think.

Now I'm curious... I know I've got a few items with LCD screens in my big bin of electromechanical junk I could try. If I do I'll make a movie, but there's no way I could compete with the awesomeness of the original movie.

Anyone have any idea of the electrical properties (resistance as low as possible I guess) that I should be looking for in a candidate for conductive glass?
 
2009-03-17 07:08:51 PM
You want low resistance (obviously, as you noted). But you also would ideally get optical transparency. Pretty much any glass should be ok. Just make sure you can see through it. That should give you enough of the visible spectrum for this to work.

VODAK!!!

Is it just me, or does a video like this seem absolutely perfect for fark? Enough science and fun, with the silliness to keep you watching.

Also, I hope this guy teach entry level physics labs, this is exactly what you need to get students interested. I would say he should teach middle school or high school science, but i wouldn't wish that on anyone.

/I've had some awesome science teachers before, fun people.
//In the Myers-Briggs typing profile, I would have to say they are iNtuitives not Sensing types.
/// NTJ or NTP types, definitively not STJ or STP types (those guys are never any fun :p). I or E is probably fine either way.

(to clarify, the author seems more a chem guy (or biochem) than a physics guy, especially given the equipment in the lab. I just prefer physics :p)

So if every civilization that made pyramids had a solor cell on every step of each perfectly alingned structure, making alcohol and tea and soot, and the white stuff, they could have lit the interior of the strucures.
Even recharged space ships?

Wait... You're a friend of the guy in the video?

So... Do you know Moist and The Pink Pummeler, too? Did Dr. H. make this before or after he joined the Evil League of Evil?

Why build a pyramid just to light up the inside?

So now you understand why there's traces of Gorilla Glue on the Great Pyramid.
