The use of electric eels as batteries...

Postby Grincement » Wed Oct 18, 2006 8:40 pm UTC

Can anyone tell me how easy it is to use an electric eel to power an emergency radio?

I know it's a very stupid question but due to a project i'm wokring on at the moment, this cropped up and well it's made me curious.

Any ideas?

:D

As for the eels, without any knowledge, i'd say the power they produce is too sporadic, but yeah, i don't know

Previous speaker was still funny tho :P

As far as I know, eels tend not to generate continuous currents, which is what you would require to have a radio worth using. It may be possible to get them to do so- however, I would rate it "ridiculously hard" on the easiness scale.

Looking at wikipedia- "When agitated, it is capable of producing these intermittent electrical shocks over a period of at least an hour without signs of tiring." While you have duration there, the "intermittent" seems to make this impractical.

You could always charge the battery instead of a direct electrical current.

It could charge a capacitor, but you know what, the hand-crank model would be more efficient.

Then again, if you're using an electric eel to power things, you're really not looking for efficiency :)

Unfortunately, it would be simlar to trying to harness the energy that comes from lightning :(
It's too much energy too fast, and for too short a time.

Yes to both. If you had a slope you could use a potato in the same manner.

Last time I checked, breaking the law that forbids perpetual motion machines had, to say the least, disappointing results.

It wouldn't be a perpetual motion machine though if you were rolling a potato down a hill. Unless said potato was perfectly round, said slope was perfectly smooth, and it was unlimited in length...

Hahahahaha! I was gonna do that, I just don't have a scanner in my room and I got distracted by "As you can see, the weather today will be cloudy with a high chance of fuck you"

In fact I only came back just now to retract my offer of artist for hire based on my friend has convinced me I can pull off a webcomic :P

I don't mind though, I commend your speed and recognition of genius 8)

Thank you, thank you.

I humbly accept this award. And I think it's fair to say, I owe it all to MSpaint. Thank you MSpaint, you're the best.

Edit: Seriously though, if you do a comic that would be fucking sweet. I have high expectations!

That reminds me of something. And because I still can't figure out how to draw scalable shapes easily, here it is in paint...

It should also be pointed out that, to even get that intermittent hour of charge, you'd have to "agitate" the eel. In other words, it would have to be so terrified that it would completely wear itself out generating charge for a solid hour.

If that's not animal cruelty....

i too want that game. it looks to be something rather fantastic. i mean, common u cud do damn near anything, "hey look, a giant pit, hey look a whole heap of enemies"
and then u dump the giant pit on the enemies and throw boxes in on top. mmmm
and i also want a potato that just keeps on rollin, like its magic or something,
except that'd make the walls bleed or sumthin else crazy and my mother wud get shitty

Thanks for your help guys...unfortunately it doesn't seem possible to use an eel. I'm guessing the team is going to have to go back to more conventional methods, like lemons.

However I do like the idea of the potato...makes an interestinbg conversation piece for people visiting your house, apart from they would probably drop down dead from confusion...

If you fire the potato through the ergosphere of a rotating black hole you could get energy that way...

Otherwise an electric eel attached to a wheel (with a horizontal axis) going around and around charing a generator.

Or instead of an infinitely long slope with a single potato you could have a finite length slope with a very large number of potatoes at the top. You'd have to hire somebody to place the potatoes in the top of the slope, hire somebody else to go out and buy more potatoes, and hire a third person to chill out at the bottom and make chips.

if you had a huge huge amount of electric eels in a huge huge tank could you not just use the tank to complete your circuit and not have to be that cruel to them to get some sort of constant flow?

or maybe the internal conflict in the tank would be enough stimulus to keep the charge coming without you having to do anything... ah, i really have no idea, but it is a nice idea, if i'm ever very rich i might have a room powered in this fashion, with the eels inside the walls.

Or you could drive the tank to the closest powerplant, aim the cannon at them, and ask very politely for some free energy please.

I think that would fit well into the "i am so geeky that I" if you did :D

perhaps, but i think it is cool geeky... and i'm not geeky enough to post in that thread anyway, i'm scared my credentials would be called into question and i haven't even looked at maths/physics for over a year, and only a little chemistry. and that was only higher level anyway (i have no idea what the equivalent of higher is in other parts of the world, basically it's the qualification that gets you into university)

So one room in a house could be powered by a the infinite rolling of a potato...the other room powered by electric eels.

Hmmm, now just another 8 or so rooms to power...

germanium radio + duct tape + electric eel.

all good :P

(them radios that use only the power of the radio waves... AM only)

I have seen schematics for a beer powered radio also, and believe that it is highly likely to work.

EDIT: so you get the eel really smashed
