Okay, let's say it's the propeller that makes the most noise, so why don't we make them quiet? Huh? We could, too. The wings of some birds are equipped with kinds of very fine "feathers" which make their flapping imperceptible. : Mrgreen:
As for the powerful 2T, it is enough to increase their displacement to compensate for certain losses due to a quieter exhaust.

Winglets reduce the shear at the tip of the blade but do not cancel it ... it is impossible to make a truly silent performing propeller without having monstrous dimensions ...

Kind more than 4 m in diameter for 20 kgF ... : Cheesy:

So the question is simple, what about football's carbon footprint?

In econologist memory I have never found a study on this subject (I did not look too much either ...)

Bread, wine, games ... and you will tame the people of the fields ... Is that their thing?
...

There are already so many fundamentalists in the green religion that it does not seem wise to me to suggest that they launch fatwas against football.

And the carbon footprint of all webmasters? The forum with this kind of discussion are not more necessary than football. What would it be after football banned because of CO2? The ban on all mechanical sports obviously? The ban on all cultural activities where you cannot go by bike? And even the bicycle? Shouldn't we ban it and all sports since our lungs emit more CO2 during physical exertion?

Without being a fan of football, and finding shameful what the players win and stupid the behavior of many supporters, I nevertheless prefer the "panem et circenses" to any green or not green dictatorship. Limiting carbon does not give all the rights, even none. It's not just CO2 in life!

Eliminating a team is also good for the covid!

So in a few days, we will also have to do the EURO2020 COVID review, it's already starting elsewhere ...

And meanwhile, among psychopathic billionaires in the mental age of a spoiled 7-year-old:
Billionaire space race: Richard Branson wants to get there before Jeff Bezos
Image
The space race was packed Thursday, July 1 among milliardiares. The wealthy Briton Richard Branson aims to go to space aboard the Virgin Galactic company ship from July 11. He hopes to tackle his rival Jeff Bezos, whose trip to zero gravity is planned for him ... on July 20.

The competition rages between the two men. Richard Branson and Jeff Bezos both started space tourism companies, which offer short suborbital flights.

In early June, the boss of Amazon announced that he would be part of the crew of the first manned flight of the New Shepard rocket, developed by his company Blue Origin. He thus thought to steal the scoop from Richard Branson, who had long said he wanted to participate in a test of Virgin Galactic, before the start of regular commercial operations announced for 2022.

But the Briton pulled the rug out from under his competitor's foot on Thursday, declaring that he would be among four people aboard the VSS Unity spacecraft, which must therefore take off on July 11 in New Mexico. The schedule is however suspended to weather conditions as well as to "technical checks", Virgin Galactic said in a statement.

You're not nice Guy! He has the "right" because he has "passed" his life on the human value scale.

That is to say that he has selfishly accumulated more wealth than 99.99% of other humans ... a "great success" therefore from a human point of view! : Mrgreen: : Mrgreen: : Mrgreen:

What does his competition to "save the planet" give? Let me guess ... Nada?

Their billions would do better to be invested in the real fight against global warming ...

No kidding...

Covid-19: Does the Euro football play a role in the resumption of the epidemic in Europe?

While the Delta variant threatens Europe with a new wave of the epidemic, the WHO calls for better monitoring of supporters of Euro football, where barrier gestures are not always respected.

(...)

Last week, cases of Covid-19 contamination increased by 10% in Europe after ten consecutive weeks of decline, the WHO warned. "There will be a new wave in the European region unless we stay disciplined," WHO Europe director Hans Kluge told an online press conference last Thursday. The increasingly active circulation of the Delta variant is undermining the progress made so far by the various countries to eradicate the epidemic. Russia and the UK, in particular, both host countries, are hard hit by the strain detected in India. The WHO expects it to constitute 70% of new European cases in early August and 90% in late August.

Christophe wrote:You have doubly wrong Guy:
a) 80% of the decibels of a paramotor is the propeller ... so lost guy! Electric paramotors are far from silent!
b) The engines are efficient 2-stroke ... it is quite difficult to make an efficient 2-stroke very quiet but that would not be of much use for the reason a)

On the other hand, we could make your remark to the manufacturer of mowers: why are they still making so much noise in 2020 ?!



For the same reason that your paramotor : Mrgreen: the blade is neither more nor less than a propeller .... Listen carefully to the mower of one of your neighbors rather distant .... You will hear more the noise of the blower than the fart fart of the engine ....

And the big fashion is now robot mowers which are still quite silent .... Even if there are still many irreducibles of the petaradant motor mower (of which I am part) .... These dinosaurs are brought to disappear ....
