Uranium is 70% denser than Lead.
The energy stored in the drive weights of a long case clock could therefore be substantially increased if the weights were made of depleted Uranium rather than Lead.
This could allow an eight-day clock to be reworked as a fifteen day clock, or have more elaborate
chimes for the same case size and drop.

You want dense? I'll give you dense. [neutrinos_shadow, May 07 2010]

Hardly seems worth the effort of depleting it just to gain a
fraction of an AMU. |
|
| |
No, when the weights come into close proximity, the surroundings get warmer. |
|
| |
this is a case of technology potential versus cost effectiveness. Depleted uranium is a lot more expensive than lead. plus i dont think the army is gonna let go of any soon since they need it to throw at mountains in other countries. why not double the size of the weight instead, Much cheaper. Remember the addage K.I.S.S. |

Hah, you think that's the best we can do ? This merely describes an energy storing sub-assembly. If you want a totally dangerous clock, then we'll start working up a specification. Some sort of Death Clock ... |
|
| |
A cuckoo clock, where every hour the door opens and a vicious and hungry swarm of hornets comes out? |
|
| |
//when the weights come into close proximity, the

Frisch's "Dragon" experiment? |
|
| |
Uranium? Childs play.
If you're looking for dense, get some Osmium - twice as dense as lead. |
|
| |
Could the weight be modelled to look like Sarah Palin? That would increase its density by a significant factor. Dense-baby-dense. |
|

// without the toxicity and obtainability // |
|
| |
Actually, Osmium Tetroxide has some interestingly toxic attributes ... |
|
| |
//Osmium Tetroxide// Yes, I had the same thought: was
going to say it was perfect for the Death Clock. Was then
disappointed to discover that *bulk* osmium oxidises only at
high temperature. |
|
| |
But you could still make a Death Hourglass with powdered
osmium .... |
|
| |
... with the unoccupied volume filled with a persistant nerve gas. Excellent. |
|

OK I would like a long case clock with the weights of solid gold. Thanks in advance. |
