Did you know that...

I always think of this bit from The Goon Show:

SEAGOON:
A big crowd of people here today.

ZOO KEEPER:
Yes, I know. We let 'em in for the animals to look at, you see. Trouble is, we have to lock the boa constrictors up so the kids don't get at them, you know. Lost four boa constrictors last year, kids taking them home all the time...

You can't get the wood, you know...

DYKT there's an exhibition about pirates on in Museum of London (Docklands) next month?

Griffin and Bart  NB

[Griffin NoName]

Love the Museum of London. Haven't been there for years though.

[Swatopluk]

Over here we get flooded this year with exhibitions about a guy who possibly has never set foot on a ship* in his whole life.

*real ships, not river ferries or pleasure boats for small bodies of water.

Wow.. two things that amaze me: how much energy in terms of calories* is available in food, and how little energy we actually use (in terms of wattage) compared to our appliances. 



*one kcal (food calorie) is the amount of energy to warm a kilogram (one litre) of water by one degree. Now think of one of those little 100-cal snack packets: They contain enough food energy to more-or-less boil a litre of water.

How about prolonged energetic sex with three ladies?

Don't confuse heating and boiling. To get stuff to the boiling point is cheap and easy. But to get the liquid to turn into steam takes a wee bit more effort.
To get one mol of water (18g) from 0°C to 100°C takes just about 7.5 kJ but it takes about 44 kJ to turn the same amount from liquid to gas.

How about prolonged energetic sex with three ladies?

Apparently half hour of energetic sex burns ~150 calories but the refractory period can last from 10 minutes to hours depending on the individual, so unless you are one of the few individuals that can keep it upright after one, or a very short refractory period the other two ladies may become seriously displeased.

Hence the waffle-word 'more-or-less'. Incidentally, I was meaning to look up the ΔH_vap for water, to see how many frigories I can get per litre of evaporation (see the Water Cooled Air thread).  As I will be working with greater than a beaker's worth, the number is 2257 kJ/L or 2381 BTU/L in air conditioning terms.

There are three solutions to this problem: One is to make sure the three ladies are of the inclination to continue the erobic activities without male assistance (which seems to be a necessity regardless of refractory periods; I cannot fathom how to simultaneously seal three bottles with a single cork).  The other 'solution' is to eliminate the refractory period by lasting for more than a half-hour - YMMV on this one. The third is to not make the phallocentric error of assuming that sex is a physiological monologue carried out only by one body part.  

I have never really understood the very common heterosexual male's multiple-partner fantasy in terms of the logistics (barring the solutions above, with emphasis on the first).

In this case it is assumed that the minority rules
An oligosome (excluding gang rapes) with one female and several males is seen as female controlled.
From a practical point of view a male caracole on the female would look most efficient with just enough males to cover the reloading period.

[Roland Deschain]

How did a conversation about calories get onto simultaneous multiple sexual partners? Not that i'm complaining, though. It is an interesting experience though, and one that needs both stamina and ingenuity, not to mention the skills of a cunning linguist (and maybe Vitamin V as you get older).

[Swatopluk]

A caracole would be sequential

It's the squidlings fault. They encourage off-topic.

[Aggie]

All I can say is that I definitely need more....  calories that is.
