Sorry, I thought we were using the left hand rule

 

Not currently.

 

Your maths looks plausible, it's your units I question -- a BTU
is an imperial unit so it's the energy required to raise the temperature
of a pound of water by one _Fahrenheit_ degree (specifically, from 60 F to
61 F). So your figure should be multiplied by 9/5 -> 32610.

32610 BTU is roughly 32610*1.06 = 34,567 kjoules.

150 kg of water raised by 54.9 Celsius degrees ~ 150,000 * 54.9 =
8,235 kcal = 34,445 kJ. Compatible, given the approximations. Over
3 hours that's an average of 3,190 W. How big are your solar panels, about
4 or 5 m^2?

I thought you wanted to prune this cascade

 

I couldn't give a fig.

I thought the choice of unit was OK. Its a bit of domestic technology.
Most domestic technology uses the BTU as a guide as to beefiness for us
somewhat less scientific types. Air-conditioners, boilers etc. all come
with this mine's bigger than yours willy waving figure attached to the
box.

Due to the sunpowered nature of the panel manafacturers aren't,
reasonably enough, willing to commit themselves to numbers on the box.

Units of measurement are also a bit of a personal thing. Us non boffin
types do get a bit emotionally attached to our units and what they mean
to us. I can tell you that a kilometre is 1.6 miles or 1000m but I *know*
what a mile is at a deeper level. How it feels to walk it, how long it
takes, how many of them from here to that wiggly road I like. We get
attached it would seem.

Panel thing is quite small at 1m x 2m big. Water is fed by gravity into
the panel from the bottom and works on the heat rises principal to
shuffle the water through the system I think. Primitive but effective. It
still works so I haven't fixed it yet. Theory of fixing is hit it with a
hammer. It jars loose the lime-scale and all is good or it breaks it
properly and you replace it. They normally have about a 4-5 year life
span I believe.

 

We have the capacitance deal with the charges against us.

 

But you screwed up on the definition. It's the energy required
to raise a pound of water by _ONE FAHRENHEIT DEGREE_ -- you calculated using
the temperature change in degrees _Celsius_. Use whatever unit you like,
but use them properly!

That's told him! Now write it out 100 times after class.

He's in good company though...

The Times no less...

 

Places we've chartered in the Med:

Croatia - Mainly large Marinas. Was cool when we were there (end
Sept.). Nice enough, some interesting sailing weather when we were
there.

Corfu and Northern Ionian - Some very nice harbours, mostly not too
crowded, quaint little villages to more developed, but still charming,
tourist-yachtie towns.

Southers Ionian (from Levkada). Very underdeveloped (although it's a
few years now since we were there). Very 'safe' sailing, all enclosed
by a ring of islands so protected from the open-sea weather systems,
although still possible to get blowy days, but often lacking wind,
especially in the mornings. Lots of novice sailors.

Athens and the Saronic gulf - Didn't much enjoy our first day, on a
new boat, with a hell of a hangover, having to cross one of the
busiest shipping lanes in the world, from Piraeus to the sea, in an
increasing (got to F7 that afternoon) wind. Much more Greek, most
places used as weekend retreats by the ore well-off Athenians.

Turkey (Lycian coast) - the best of the bunch, in our experience. Much
larger operations, thousands of yachts, yet enough harbours for all,
many of them of the 'one family, one restaurant' variety. We loved it,
and TBH the Gulets aren't _that_ annoying, although they do try. Oh,
and the standards of cleanliness and maintenance of the boats was the
best I've ever seen, and is apparently typical of the area, not just
our charterer.

Bareboat vs. flotilla. Horses for courses, but the key in choosing a
flotilla is to know what you're getting yourself into beforehand. Some
of them, notably those run by 'Sailing Holidays' take raw novices, put
them in charge of a boat, then run around chasing after them and
telling them exactly what to do, where to go at all times. Clearly
you'd hate that. Others, like ones we've used through several times,
tend more towards the 'This is where we're going tonight, let us know
if you end up somewhere else and we'll see you tomorrow' variety.

This time our flotilla was organised locally, independently from the
boat charter, and run by a Dutch couple with their own boat
(http://www.gofunsailing.nl/gofunsailing engels/Flotilla Turkey.htm,
highly recommended). Was early season, so just five and three boats
resp. for the two weeks we were there, but very relaxed, everyone knew
what they were doing.

We tend to go for a carefully-chosen flotilla if it's our first time
in an area, but as much for the social aspects as for the local
knowledge. Bareboating can also be fun, but sometimes a little lonely
and you really need to know what you're doing if there's just the two
of you (like us) on the boat.

Or, in layman's terms, 'loads'. We've been tending to go a little
bigger 35-36ft, ostensibly 'cause I need the headroom even more since
I broke my back, but they're more comfortable all round and tend to be
rigged more towards ease of use than pure sailing performance. Maybe
that's just them getting newer and better over time, I don't know.

In Greece they do tend to ask for a licence of some sort, and it
seems to have been tightened up in recent years. But mine (prior to
getting an ICC in Croatia three years back) was a real micky-mouse job
issued by a holiday company, but was accepted.

In Turkey, it seems they don't actually need anything at all. I know
we'd faxed our licences to our booking agent beforehand, but when I
offered the original to the charterer, he wasn't in the least bit
interested.

Yeah, they would though, wouldn't they.

Let me know if there's anything else I can help with.

Well you could have mentioned that in the post above instead of getting
all shouty now.

My reading skills dont cover one letter words too well apparently.

It does quite clearly state F. in a very clear and concise description of
a BTU henceforth to be abandoned as unit of measurement due to being to
complex for the ....

OOOoooH! Donuts!

 

Thank you *very* much for that.

I hope to be back to you.

 

I forgot to mention prices.

Croatia was surprisingly expensive, especially as you neede to pay
Marina charges most nights, around 30Eu for a ~12-meter boat. Food and
drink were normal western european prices; and nothing special.

Greece varies, but in the Ionian there's only a few ports where you
pay mooring fees, and they tend to be around 5-10 eu even then. In the
Saronic gulf there are more restaurants of the type where they have a
jetty, and help you berthing, handing you a lazy line, sorta thing, on
the unwritten proviso that you'll eat there.

Turkey has even more of this type of place, and these definitely get
my vote. Food at them tends to be a limited (mainly meat) menu at
~15eu p/p, including a meze of starters. Wine is indecently expensive,
like twice that much for a very mediocre bottle. Beer is cheaper. Some
of the larger ports have paying marinas, but I generally avoid these
except when in dire need of shore power or water, although some of the
smaller places have the latter.

 

I can't help but read that as the sardonic gulf.

 

And Heinlein even closer in the fifties. He specifically mentions
'personal communication devices' in several books, and several
characters carry a phone in a pocket and their conversations with others
over their mobile phones are frequently intrinsic to the story. I can't
think of any specific examples, but I'm sure that GPS could be construed
under the headings of the various location and navigation devices
employed in many of his books.

 

In the last Heinlein I tried to read I gave up when the wife of the president
pointed out that she had been darning his socks for the last forty years.
I've never actually tried wading through treacle but I'm sure it's more fun than reading SF.

 

Heinlein (especially the later stuff) is very definately *not* good SF.
More a personal expression of his various fetishes and bugbears..

"Terrorforming".

It could be just like Westworld, apart from Champ's geographical
problem: SouthMidsWorld doesn't have quite the same ring to it.

Indeed.
