You forgot to say what to do with the waste products from your engine. |

//You forgot to say what to do with the waste products from your engine//
Whilst I agree with your sentiments, [lurch], I don't think Messrs Watt, Benz, Diesel or Whittle considered the question either.
[EDIT] Why potassium?
Why not sodium or lithium? The reaction would be more violent (== energetic) for less "fuel" mass, no? |
|
| |
Or bananas? Unlike diesel or sodium, you could eat the fuel. |
|
| |
Although I think you could still eat lithium. I read somewhere it is good for you. Makes you feel better. |
|
| |
<Homer> Mmmmmm...lithium. </Homer> |
|
| |
would this be upgradeable to a cesium engine? I really like to go fast myself. |
|
| |
Awwlright you lousy steam you, look alive and give this 'ere boat a bittuv a shove.... |

//Why not sodium or lithium? The reaction

Lithium is less reactive than sodium, which
is less reactive than potassium, which is
(as jhomrighaus points out) less reactive
than caesium. |

The waste product, potassium hydroxide,
could help to counter the effects of acid
rain. |
|

[MB] Thanks for that - it is over 30 years since I was intimately acquainted with the periodic table. |
|
| |
So does this work like the baking soda and vinegar volcano? |
|
| |
lutefisk (from lutfisk, "lye fish"). Cod is soaked in Potassium Hydroxide or (KOH) to a jelly-like consistency, then served with bacon fat, potatoes, brown cheese (brunost) sauce and mushy peas. |
|
| |
So...it's like a good start then? |
|
| |

Good job it isn't served with chips - you could be tempted to put vinegar on it! |
|

No no, I think [Absinthe] might have been onto something there. Whilst Potassium is more energetic per mole, on a per gram basis, I think sodium or Lithium would probably tip the scale. |
|
| |
.... Check [linky] actually lithium is more energetic, per mole even. Hmmm. Super-fuel, anyone? |
|
| |
Given that Lithium is 6.9 g/mol and Potassium is 39.1g/mol, we have ourselves a clear weiner. |
|
| |
Potassium as a fuel is worth 5.01 kJ/mol |
|
| |
and Lithium races by at 32 kJ/mol. |
|
| |
Well spank my arse and call me charly. I wouldn't have thought it would be so disparate. |
|
| |
Yeah, but you'd only eat cod soaked in lithium if you were crazy. |
|
| |
summer break meets chemistry class meets autoshop. |
|
| |
Yeah, lithium seems to outstrip potassium. Plus, lithium is lighter. |
|
| |
You could use the potassium hydroxide to make biodiesel. |
|
| |
with sodium, lithium, and caesium, the off-gassed hydrogen actually auto-ignites because the reaction is so hot, so you'd really be making a rocket engine |
|
| |
with caesium, the reaction is so violent it's a huge explosion |
|
| |
Either/any reactive metal is going to cost you more to make than you'll get out of it pushing a boat. Lithium may work as an energy-storage scheme, but as a power source, it's crazy talk. |
|
| |
Potasium is purified with electrical current. How many Kilowatts of energy is required to purify enough potassium to create a kilowatt internal-combustion power? |
|
| |
Not looking too beneficial to me. Maybe it would be useful for a torpedo engine or something. |
