compress air at the bottom and inject gasoline and ignite.

What happens when combustion products cool down. [Freefall, Oct 04 2004]

Finger on "go" button, check around to see if there are any pregnant passengers, initiate countdown... |
|

Something for the evil bond-villain in all of us. |

I quite like this - I feel there is a use for second-hand mattresses here. its always been a worry for me that old mattresses are good for nothing. |
|
| |
1st person to say mistresses gets a slap. |
|
| |
do hope my plurals are correct - my dictionary gives me no plurals for either |
|
| |
second thoughts, quite is inadequate - this is fun. |
|
| |
except with phoenix, what goes down must go up <g> |
|

//second law of thermodynamics// |

Don't all elevators go both up and down? |
|
| |
Not if it's a one-way elevator. |
|
| |
[gnome] - are you absolutely sure about that? If so, good grief, Pioneer spacecraft are breaking the second law of thermodynamics. |
|
| |
I always thought they were "heat is work and work is heat" and "heat cannot of itself transfer from a cooler body to a hotter body". |
|
| |
Weeeeeeell, that is sort of like it but I cant help thinking that that is a bit 'old school thinking' [PeterSilly]
If you ask a friend if mine (who *is* an electrician) about any rule or principle, he generally says "What goes up must come down"
The point that I was trying to make was that there was no description of the 'coming down' bit |
|
| |
Surely the downstroke could be controlled by restricting the outflow of the combustion products. |
|
| |
-->Bang! Elevator goes up |
|
| |
-->Hisssssss... Elevator goes down |
|
| |
Actually, [gnome] it's Flanders and Swann thinking - that's entropy, man. |
|
| |
Go down via ratchet & brake.
BANG! top floor.
Kachunk kachunk kachunk kachunk next floor down.
Repeat until at bottom.
I think you could even make it work in a power outage. |

Funny thing about combusting gases: once they cool, they typically take up less volume than their initial components. It's the heat produced during combustion that causes the expansion. (link to come) |

i had to delete the post with the enitrely false definition of the second law of thermodynamics. sorry but i can't stand misinformation |
|
| |
buddha, <SLAP> that hurt me more than you sweetie. |
|
| |
//i had to delete the post with the enitrely false definition of the second law of thermodynamics. sorry but i can't stand misinformation// whats that all about? |
|
| |
Someone tried to say that the second law of thermodynamics was "what goes up must come down" - sheesh! |
|
| |
Come on, everyone knows that the three laws of thermodynamics are:
1 - You can't win.
2 - You can't break even.
3 - You can't leave the game. |
|
| |
That was me [Peter] and [davidcreede] - not entirely seriously I might add |
|
| |
noted, and i appy polly loggy, but i can't stand running into other people who think that "what goes up must come down" is a "scientific thing". And ridding the world of that mental item is one of my personal crusades. |
|
| |
..which, of course, is to be lauded. No Worries. |
|
| |
Might be good to send things into space... or shoot aliens? |
