Water vapor => greenhouse effect




by gerald » 15/11/05, 19:14

Hello
I just read today that water vapor is an important part of the greenhouse effect. It will suffice to design exhaust pipes that condense the steam if the system is efficient, it would be possible to filter this water to use it indefinitely while recovering pollution in the filter. The water tank is said to be non-existent or very small.

No need ... we have already discussed the subject and Jean Marc Jancovici has made the calculations for estimating the releases of water vapor from the combustion of hydrocarbons compared to the evaporation capacity of the oceans.

Well the result of the quantity of water coming from the hydrocarbons is of the order of 0,0005% (I no longer have the exact figure in mind but it was in these waters) of that of the oceans.

So overall it is very negligible ... on the other hand it can create regional disturbances.

For example, in Schiltgheim, where the largest brewery in Europe is located, it is common to have more fog (see snowfall) than in the rest of Strasbourg. This obviously comes from the steam of the manufacturing process.

In the case of "pantone" engines or hydrogen engines, it seems to me that the water vapor emitted would necessarily be more important than for operation with hydrocarbons ... ??? NO?

well in this case we go to 0,00051% .... this remains very negligible.
Then, if steam is a greenhouse gas much more powerful than CO2, its average "lifespan" is 2 weeks before falling back in the form of rain.

That of 2 years of CO120.

Well it's funny, it is, among other things, one of the arguments of critics of the water engine (assuming it exists): what would be the consequences of such discharges of water into the atmosphere ...
