zamysli sa nad tym, ze motor v sucasnosti najvacsej lode ma na vysku 15.5 metra, sirku 11 metrov, dlzku 25 metrov a pracuje 280 dni v roku. Okrem toho neexistuju ziadne regulacie emisii a vsetky tieto lode spaluju toto (odpad z rafineriek):
podla tohto (http://www3.epa.gov/otaq/consumer/420f08024.pdf) je priemerna spotreba auta za rok 500 galonov - cca 2000 litrov
cize 760 000 000 * 2 000 = 1 512 000 000 000 litrov
od 2015 musia lode pouzivat palivo s maximalne 0.1% siry (https://en.wikipedia.org/wiki/Sulphur_Emission_Control_Area), co je 100 krat viac ako benzin v autach
kedze auta spotrebuju 1000 krat viac paliva tak vypustia 10 krat viac siry.
On 1 January, this Sulphur Emissions Control Area (SECA), along with two zones in North America, tightened its restrictions on the sulphur content of fuel used by commercial ships from 1% to 0.1%, in line with the 2013 Sulphur Directive. Sulphur content in ship fuel is hardly regulated in other areas, including the Mediterranean, where it can be as high as 4%. A global limit will be set at 0.5% from 2020; a challenge for the industry, but an essential measure for the environment.
...tolko k tvojmu 0.1%... regulacia sa tyka len minima oblasti
... na elektrinu vyrobenu z domaceho uhlia v Novakoch.
napriklad do USA
na lodi
vsak prave...
u lietadiel ide o to ze su blizko ozonovej vrstvy ,sice ich tak necitime ,ako dole auta ,ale o to rychlejsie znecistuju priamo na mieste
...ale sme vo vychytavkach ...takze pardon

Aj keby tvoje cisla sedeli, tak ti velmi nesedia jednotky, kedze emisie sa nemeraju na spotrebovane litre. Treba si uvedomit od dokonalosti spalovania, cez filtre (v autach napriklad katy a dpf) az po cistotu paliva vstupujuceho do procesu spalovania. Potom pochopis, ze nie z kazdeho vyfuku vychadza to iste a ze spotreba je nieco ine ako emisie.

Velmi zaujimave citanie. Fakt to masove lietanie je pekna blbost pre planetu. Inak - letecke spolocnosti neplatia spotrebnu dan za palivo.
