an airplane, or a liner, pollutes more than a car, it is obvious, but calculated by passenger and by km, surely less,

the question is above all: is mass aviation justified? the mass car too?

think before you answer ... trick question. :P

you also have to see how many people in the car : Wink:
at five it is more economical / ecological than the plane especially if it is not well filled : Mrgreen:

in fact we have to see if the displacements are really justified,

and at the same time replace all these polluting fossil fuels with renewable sources of all types.

anyway we will run out of cheap fossils, so we have to play on the previous 2 levers.

What about the mass motorcycle?
Yesterday they were 1600 to demonstrate and block the roads in Amiens and it is the one who made the most ruptures, what a good example of "I pollute a max and I piss you off .." 800 g of CO2 / t.km for a car, but a large cube consumes more than an average car and pollution issue, there should not be much with a catalytic converter, compared to the number in circulation.
Technical control, always delayed, will put some order, but not before 2022? https://www.permisapoints.fr/moto/contr ... point-2018

it is true that motorcycles often have an impressive consumption compared to their small SCx and the only passenger they carry.

after it is better?
a biker alone on his motorcycle?
or a motorist alone in his car?

Otherwise, it's a good document, full of good numbers, and this table is very interesting for motorists who vomit on airplanes:

Consommation_avion.gif

Yes, a plane, with more than 100 seats, transports you to 700-900 km / h with a consumption per passenger of the order of 4L / 100 ...

There is no picture: the car (in its current design) is a daube (a scam?) Energetic!

ps: a Cessna (and equivalent) does not consume that much per passenger per km (if the 4 seats are occupied) ... See this topic: new-transport / diesel-en-Aviation legere-and-Ulm-Dieselis-gazaile-t2250.html (from the memory the Gazaille, 2 places, feels the 2L / 100.passager !! To check on this subject ...)

And the ATRs (42 and 72) are appreciated for their low consumption / maintenance load ...

reps: interesting variations and passages by mini in columns> 100 places


Thank you for this painting, I reposted on Oleocene

Some figures for a cruise liner with data collected on board:
- 4000 customers
- 1000 crew (sailors, catering, animation, laundry, maintenance, ... in 24 / 24)
- 50 tons of fuel oil / day at berth
- 150 tons of fuel / day cruising (24 hours of navigation)

If we look at the dock, 50 tons give about 50 * 10,64 * (40% yield) = 212 MWh, or 42 kWh per day per person.
This is huge compared to 4000 / 365 = 11 kWh per day for an average home. (pools and desalinization surely).

The liner has a cruising speed of about 21 knots (40 km / h). It travels about 1000 km per day.
The consumption of displacement per passenger is therefore:
(150-50) * 1000 / 5000 / 1000 * 100 = 2 liters to 100.
And 3 liters at 100 including consumption at the quay (lighting, air conditioning, kitchens, laundry, desalination of sea water, ...)
Or 3,75 l / 100 excluding crew members.
