Much snowy stuff, even more lack of warm, not quite as much
atmospheric movement and sod all solar activity at the Castle this morn, the
white stuff, a touch of frost and skywater has managed to bollocks up the
interweb thingy all weekend, every time I tried to post it went tits up and
then came back on when I gave up-ditto-ditto-ditto, so I eventually submitted
to nature and abandoned the blog until today.
All seems connected-so far, the elbow isn’t recovering that
well, been four days since the pecking and it still hurts like buggery (I know
because I have had a prostate exam).
Shortish post this morn-just in case.
Allegedly plans are afoot which would see passengers pay
according to how much they – and their luggage – weigh.
Norwegian aviation expert Dr Bharat P Bhatta’s ideas could
also mean falling costs for slimmer travellers.
Dr Bhatta of the Sogn og Fjordane University College in
Norway said: ‘As weight and space are far more important in aviation than other
modes of transport, airlines should take this into account when pricing their
tickets.’
Airline bosses are to consider three variations, including a
scheme where air-users would be charged according to their weight along with
their luggage.
Another option would see passengers paying a base fare plus
or minus an extra charge.
A third variant would see a standard fare for passengers
within 25 per cent above or below a set weight limit, with a discount or
surcharge depending on whether they are over or under that span.

Mulan Jamila, a four-year-old Bengal tiger, shares a sloppy
kiss with keeper Soleh.
The pair has become
inseparable and have regular rough and tumble play fights at the Al Khaffah
Islamic school in Malang in Indonesia’s east Java province.
The tiger was a
gift from a friend and is kept as a pet under a government permit.
Mulan Jamila has
been Soleh’s pet since the age of three months and now gets through 11 pounds
of meat a day.
Good luck with that-wonder how much a human head weighs....
And finally:
A vacuum airship, also known as a vacuum balloon, is a
hypothetical airship that is evacuated rather than filled with a lighter than
air gas such as hydrogen or helium. First proposed by Italian monk Francesco
Lana de Terzi in 1670, [1] the vacuum balloon would be the ultimate expression
of displacement lift power. …
An airship operates on the principle of buoyancy where air
is the fluid in contrast to a ship where water is the fluid. The density of air
at standard temperature and pressure is 1.28 g/L and 1 L of displaced air has
sufficient buoyant force to lift 1.28 g. Airships use an airbag to displace a
large volume of air; the bag is usually filled with a lightweight gas such as helium.
The total lift generated by an airship is equal to the weight of the air it
displaces, regardless of the materials used in its construction or the gas used
to fill the airbag; However for flight it is necessary for the total lift
capacity to exceed the ship’s weight, which includes the weight of the gas used
to fill the airbag
Using the molar volume, the mass of 1 L of helium (at 1
atmospheres of pressure) is found to be 0.18 g, since every displaced litter
provides 1.28 g of lift the effective lift is reduced by 14%.
Vacuum airships would theoretically replace the helium gas
with a near-vacuum environment and would theoretically be able to provide the
full lift potential of displaced air. The main problem with the concept of
vacuum airships however is that with a near-vacuum inside the airbag, the
outside pressure would exert enormous forces on the airbag and causing it to
collapse if not supported. Though it is possible to reinforce the airbag with
an internal structure, it is theorized that any structure strong enough to
withstand the forces would invariably weigh the vacuum airship down and exceed
the total lift capacity of the airship, preventing flight …
Worth a try though....
