The truth and myths about methan-io


The-Largest-Architectonic-Buildings-in-Nature-2.jpg


this a termite nest,
have you any idea how much produces?
about 2-3 % of global methane emission is by termites.
does that mean we have to exterminate termites? in the name of global warming?

Natural gas is produced by bacteria and microwolrd, and usually traped under rock,
do we have any idea of how much is not traped, but goes straight to atmosphaere?
only human wastes from a city that are buried or through waste water released etc are about 1/3 of the city demanded power.
these are beans
7-_Legumes_W1812_gi659524906.jpg


have we any idea of the methane produced in our stomachs?
and by our domestic animals like pigs cows sheeps goats etc?

So I wonder what is better a CO2 gas
or a CH4 ->CH3 +H gas?

and how this energy would be 'controled'

No more pork or beef steaks for you (brizoles), Yetos! No more bean soup(fasolada) for you either.

But your AC still uses the bad R410A.

Fujitsu's figures completely miss the only two refrigerants that are climate-friendly: R290 and R600A. From this year these are the only types allowed in the European union. Even R32 is banned.

What does productivity have anything to do energy consumption? In developed countries, lower energy consumption is associated with more advanced technologies. Anyway, most European countries have a higher productivity than the USA according to the latest OECD data.



Why do you think that protecting the ozone layer is more important that fighting global warming? That was an important issue in the 1980's, but measures have been taken and the holes in the ozone layer have since healed.

Are we talking about the European Union or individual countries? It seems to flip flop. The U.S. is the most productive economic nation in the world. It's not even close. China is number two, but they are catching up to us.

If we want to divide Europe by country to cherry-pick data points, I could easily divide the U.S. by state as a counter. For example, I'll put California's per capita productivity against any nation on Earth.

There are four nations on the planet that are both net exporters of energy and net exporters of food.

The U.S. is one of the four.

Indeed, until we find a method to gather and control this energy,

You have no idea what productivity means, do you? You confuse productivity and GDP. Productivity is is a ration of GDP over a time period, for instance the GDP per hour worked. Countries where people work long hours, like the USA or Japan, tend to have lower productivity than those that work short hours and take lots of holidays to produce the same wealth. It may seem counter-intuitive, but if you compare 2 countries with equal GDP per capita, the country with higher unemployment is the more productive (as less workers produce the same GDP).

If you had checked the OECD data I linked you could have answered your own question about the productivity in the EU vs individual countries. The GDP per hour worked in 2018 in the EU was 108.2 USD, while in the USA it was 104.7 USD.

China's GDP per hour worked is very low, around 10 USD.

I have had enough of people like you who have no idea what they are talking about. I am going to get rid of people who keep wasting my time with inanities.
 
Air conditioners can contribute to the development of sick building syndrome in certain rooms and in a variety of conditions. People in an infected room may experience dizziness, dry throat, itchy eyes, and nausea.


Studies conducted by the Journal of Occupational and Environmental Medicine have found that forced air conditioning with split systems, window and central air conditioning, much more often provokes symptomatic health problems, which is rare in natural ventilation of buildings.
 
Spain has restricted cooling to 27 C and heating to 19 C.

Climate change has created drought, with river levels falling. There is an issue with low river flows where power plants need to turn down to avoid heat pollution creating a fish kill in the cooling water outlets.

An Irish company (Exergyn) has come up with a new airconditioning system completely devoid of greenhouse gases. It is based on a substance called a shape-memory alloy (SMAs). The new AC is not just more eco-friendly but also 30-40% cheaper to run. Sounds revolutionary.

Awesome!! :)
Going to be honest with you, just reading the different Moderators arguing about air-conditioning just made me get out the popcorn. :D
Yeah, the big problem with every American ditching air-conditioning Willy-nilly is that it would mean laying off hundreds of people from the workforce. But I?m glad that Ireland is taking the initiative and manufacturing an eco-friendly air-conditioner. :)
 
I was one of them, I know. :)

Let me tell you, with the temperatures and the humidity this summer, they'd have had to pry the control out of my cold, dead hands.

I did, today, turn it off and opened all the windows. Thank-God for the coming of autumn! ​
 
With the possible return of intensive use of coal due to the energy crisis in Europe, the use of ecologically correct refrigerants in air conditioners seems to have become a minor problem Will we will see the return of smog clouds: A mix of soot and CO2, sulfur oxide, nitrogen oxides, volatile organic compounds. In the face of coal, even oil looks clean….

This picture taken from my house. This is the Northern Puget Sound looking strait at the Cascade Mountains. The sea is so close to the Cascade Mountain ranges that the two tend to keep Western Washington cool in the summer and the Mountains block out almost all of the snowstorms in the winter.
We have an air conditioner but the sea breeze tends yo work better; as long as there is a bug net in the windows. :)
But I suppose with West Virginia, you?d need other methods to cool off.

Live on Long Island; we got socked with a really, really hot summer. I love the sun, but I can't take the temperatures in the upper 80s and 90s with high humidity.

I swear it's genetics. I'm my father's daughter where this is concerned. I get fried by the sun no matter how much sun screen I wear, and I'm really prone to heat stroke. I don't think I perspire enough. Even in the shade I can't take the heat no matter how much I drink. I have to go sit in the air conditioning.

My mother was the opposite. She would bask in the sun for hours like a lizard. She loved it. My husband and both my children are the same. I'm the one always complaining and running indoors. :)

There is a bunch of nuclear, solar and wind in Europe. You can see a live map. Poland is mostly coal.

The US President Trump warned Germany in 2018 that their reliance on Russian gas from Gazprom would make them dependent on Russia and they laughed at him at the time. Now Germans are stocking up on firewood.
