Battery/LED challenge. play if you dare!


Recommended Posts

easy win: take an iron bar and a nice long piece of wire, wrap the wire around the bar and then connect the diode to the wire and go and sit it next to an electricity substation. It will flicker at 50Hz unless you rig up a cunning array of diodes and capacitors, but it will work as long as the LED lasts.

it would indeed, and also not come under the catagory of a "Battery".

the secondary winding of a transformer would be closer. but non the less, as a whole, the idea certainly has merit :)

Someone needs to make some sort of nuclear battery. That would be cool.

 

YT, you speak Russian, go hit up the reds for some uranium.

Posted

Indeed I speak some Russian, of that you may be sure :)

but be equaly sure that Uranium is not something I wish to posess and Russia would not be the place to buy it from anyway :)

having said that of course, a nuclear battery doesn`t always use Uranium, very seldon in fact :)

Hey i only got 1day and 3hrs, what metals did you use.

I used a Zn,Cu with a KNO3 salt bridge and sulfate ions of tehm for the solution. (the salt bridge was what let me down)

An allittle electroplating was going on.

BTW i was a couple of gms over the limit( 27gms over)

Posted

not bad! :)

maybe try a carbon bridge next time, it`s quite inert and would weigh that little bit less. Nice work! :))

ok mines done and working.

it was activated today at 12:53 pm GMT

when a few more have done theirs and are lit, I`ll post what I made it with and how long it lasted (or didn`t LOL).[/quote']

 

which parts of that count toward the weight? is the stand included or just the tubes and other things attached to the LED?

"I present to you, the default winner of this competition, Nuclaer Boy"

 

David Hahn rocks indeed. :)

 

"Unitednuclear.com sells Uranium"

 

These days they only sell uranium ore or marbles, and other rather boring types of uranium. :) They used to sell actual, probably about 3% U-235 containing nuclear reactor U-fuel pellets! I'd like to get my hands on a couple of those. :>

They now sell depleted Uranium metal - http://www.unitednuclear.com/chem.htm

Very expensive, though.

I did weigh the entire thing incl the stand in mine, but you dont have to, as long is it isn`t part of the actual battery itself, related support materials needn`t count if you don`t want them too :)

Hey YT i noticed your pictures of your LED were cropped...whats that wopping great motorbike battery doing sitting there in the background.Hope your not cheating,and if you look in the left hand corner you can see the grill from a £12.99 electric fan from ARGOS

Posted

the shiney metal thing in the left is my Coffee mug.

the round thing at the back is a laden jar made from 2 margarine tubs and tin foil.

the only bit cropped is just the pos to neg link between the cells.

 

no bike batt or fan :)

are you Mental or something!???

 

anyone can clearly see that the magnallium electrode in right hand test tube contains a Nuclear Battery (as seen/used in the Bionic Man).

 

you spent all that time looking for cheats and missed the totaly obvious :(((
