Could someone knowledgeable (As opposed as someone with opinions) tell us more technical details here ?
The experiments i heard about were with classical oil guzzling cargoes which used wind as an additional source of propulsion to decrease fuel consumption. Long ago i heard about experiments with big kites. It seemed cute but i haven't heard about them since. More recently i read about other ships using vertical cylindrical sail using the Magnus effect.
Each time the advertised fuel saving were modest. Not much above 5%.
There are a few commercial nuclear cargoes out there but they are severely boycotted. As far as i am aware they operate mostly along the Russian coast. I do not foresee the nucleophobes laying down their arms soon.
Does it means some are trying to switch to gas-powered turbines ? That would not be a very good news because gas extraction itself can be very polluting. For example when methane is released during extraction. But on paper that would reduce the CO2 emissions of the ships themselves. And displace the rest of the pollution !
You are too much limited by the space (Especially in Europe) and the cost of the pumping station with artificial reservoirs. It is a "dumb" problem of massive civil engineering requiring lots of concrete. But really lots. There are also other projects which look nice from point of view of a science or technology enthusiast which do not pan out because of their economical costs.
Like the offshore wind farms coupled with artificial islands serving as water reservoirs for pumping stations. It is their price that kills them.
And you would have to build many of them. Several times the actual storage capability.
Besides, theses reservoirs have a gray energy. You need energy to make all that concrete. And in some cases you drown ecosystems. And sometimes the drowned vegetation ferments and that produces even more CO2 than a forest fire. Sometimes there are bacteria in the slit of you reservoir and they fart methane which is not environment friendly.
I i wanted to sell a Linux distro to a non geek audience i would show people do fun stuff with it. Not useful things. Probably playing video games. And that is actually the weak point of Linux.
That being said, even if i think Linux is very handy and easy to use, i do not believe it is for every person using a computer. And i do not believe computers are for everyone.
I love my nerd world, my nerd friends and colleagues. But there are simple stuff that doesn't go trough our thick skulls. It never came to your minds people do not learn to program simply because they do not specially desire to do so ? They do not consider it an important skill, they have no curiosity about "how it works in the inside" and often consider an electronic device that needs any intellectual effort a poorly designed device.
I loved my commodore 64. I learned to program a little bit on it. But it is because i was curious and educated by parents that encouraged that trait. If we lived in a world where computers were ubiquitous but similar to commodore 64's, they would not learn to program because you have to to make a C64 work. They would buy consoles.
I have similar conversations with some of my nerd brethren about maths. I mean, the few ones that more or less realize that most people know very little maths. They speak about the difficulty of some abstract concepts, the quality of the teachers, the small number of math hours at school. But they do not get that most people do not desire to become whiz kids. Eventually they find them annoying, or pedant, or arrogant. They are not curious and are not raised to become that way.
They may be embarrassed by the social consequences of their ignorance. But it is a pecking order question for them, nothing more.
Same kind of reasoning when talking about why people are not athletic while they have an able body like everyone else, etc...
If he wants to send a silly payload, he should make an enormous inflatable Russel's Teapot in orbit between Mars and Jupiter. Big enough to be seen from a terrestrial telescope.
Some people have argued that Linux does not work out for bureaucracies, civil servants or "large organizations". That made me laugh.
The French Gendarmerie (miltarized police) switched to Linux. But the organization was different. For example in lieu of bitching about non microsoft word processors not being compatible enough with whatever version of microsoft word, they dropped the proprietary formats and went to the.odt format. So, microsoft incompatibilities are not their problem anymore.
Because they made choices. And it worked out for them. A wikipedia summary here:
The second advice, the one who says you have to uninstall PlayOnLinux. All i had to do is rename the file i downloaded with some name in.exe. It was two weeks ago.
But i agree it is a hassle. I successfully ran sidplay95 on it too.
IL2 sturmovik flat out refused to install. Falcon 4 BMS worked but without recognising properly my HOTAS so there was no point. I have not booted windows for more than a year.
When i saw your post i thought i was going to see a video of one of the first MS-DOS popular flight sims and was thinking about posting a commodore 64 retort. I am beaten. I love that retro stuff.
If we want to take advantage of a 8K monitor for simming, the power and prices of graphic cards better improve. It is hard enough on those who use three full-HD monitors.
In flight simulators, especially in combat flight simulators 4K monitors are said to be below what the naked eye can do in real life. When you have to identify visually a contact at long distance actual screens are not enough.
I had a brief affair with winamp when i shortly used winXP on my pentium 4. I liked it. It could play everything i would throw at it.
I quickly switched to linux and used the media player du jour. AmaroK when i was on KDE. Rythmbox when i used GNOME2 then when Ubuntu switched to unity i switched to XFCE and i use gmusicbrowser since then.
Plus VLC for some proprietary media and sometimes an old sidplay for win95 i run on WINE when i want to listen to commodore 64 music.
I heard a lot of positive comments about clementine. I never tried it.
As an engineering physicist, i use and have used extensively mutliCPU calculations. But they were always running on some sort of UNIX like system. Commercial or not. And the needed tools already exist there. Without silly restictions over the number of NUMA nodes or unwanted telemetry or whatever...
Of course, i work in a field where windows is nearly inexistent. So i am very ignorant about this universe but who would be the customers for this version of windows ? My electromechanical engineer buddies use windows for example to do CATIA stuff. But as far as i know they do not use massive multiprocessor rigs to do so. Also, it is funny to see so many of them using outdated version of their OS. I have a friend working in the space industry that still has a workstation running winXP. Not connected to the internet.
When i was in university all the heavy duty work was done on 'Nix that is what the mainframes ran.
So i am willing to read an explanation if someone is kind enough to provide one.:)
Who the hell cares what greenpeace says ? I do care about nature but i certainly pay no attention to what greenpeace says. And hippies in general.
They aren't a scientific institution, they are a lobby group for simpletons who cannot abide by the conclusions of scientists when they differ from their religious preconceptions. They are rather anti-science. They fish arguments from fringe individuals and see most scientists or engineers or physicians as suspects and in collusion with some vague plot from the industry they consider a priori as evil.
I liked them when they were defending the whales but nothing more.
Actually, finding out what to do to favour responsible behaviour in the industry and what to buy is extremely complicated. You need a lot of input from a lot of different kind of good experts. And the conclusions are not always intuitive.
Like when i read that depending on where you live driving an electric car pollutes more than driving a diesel. Or in some places installing solar panels isn't green because of the configuration of the electric grid. The answers are never simple.
That is why we need robust institutions with their own experts. As independent as possible.
I already switched one of my 900SD ASUS netbooks to debian because xubuntu is slow on my 32 bit celeron M @800mhz. Makes playing some SCUMMVM games more difficult.:/
Netbook's hardware work fine. Bought them in 2009. No reason to switch.
In the industrialized countries, it's the industry that weighs in the costs of electricity and they are very touchy about it. So even a small increase in costs for the sake of renewables is out of the question. Last i heard The Spanish industry whined a lot that the choice of solar thermal had made their electricity bills so high they had become uncompetitive.
Private consumers are a different animal. They often can afford more or less reluctantly the prices hikes due to renewables.
So since Morocco doesn't have much in terms of heavy industry it may work there.
But i wouldn't want any European country dependent of another country which refuses to take back its deported criminals. Morocco is basically using Europe as a dump for its undesirables.
The European EELT will cover the southern hemisphere. So it is logical the TMT people want to build their instrument in the northern one.
Except there are no that many sites. You need a calm and clean laminar atmosphere and a high altitude. Sites facing an ocean to the west are good because it is where the dominant winds come from. No hills or mountains there to create turbulences.
South California is in Mexico, a moderately stable country plagued by banditry and mafias. Some people have suggested Morocco for European scopes but the country isn't very secure either. The Tibetan plateau is behind mountains which generate turbulences. The Canary Islands are nice, but not as nice as Hawaii in term of altitude and dryness of air.
As already pointed by another poster, the French press gives a different account.
They already have done a small pilot project with a one kilometre long strip. They say it was a success without going into specifics. They also say that such one kilometre long strip can provide lighting to a 5000 inhabitants small town. Not that it can power it fully. Quite a difference. They add that the project could be extended to the point 1000 km of roads would be equipped that way over a time span of five years.
And i doubt Royal (who is indeed not a very smart person) has five years ahead of her. There is a presidential election in France in 2017 and whether the current socialist excuse for a head of state will stay in place is highly questionable.
They were trying to protect Turkmen islamists i guess. Trying to show some muscle by ambushing Russian planes which were not expecting it. I think the turkish politicians, that Erdogan redneck first, do not realize what they have done.
By the way, the Russian ministry of defence has issued a statement:
-Bombings will continue -Bombers from now on will be escorted -The cruiser Moskva will move north to provide cover with his 64 big big S300 surface to air missiles -They will deploy ground to air missiles (where ? which ones ?) -They will "engage" any hostile or provocative action by fighters or SAMs (Read, if we want, we shoot first)
Yes, but i've been told by real life pilots that it cannot distinguish a -modern- MiG-29 from a Su-27 or 30. Disclaimer, i am not a real life pilot myself.
They are islamists. The only "moderates" are in hotels in Turkey; They have no power and are nicknamed the "five star opposition" because of the five star hotels they live in. For the Russians, a beardie is a beardie.
There is neither "the Russians are bombing moderates while they promised to bomb DAESH" They said form the start there were no moderate islamists and even joked they bombed moderate islamists with moderated bombs "which have more pleasant colors".
Turkey and Saudi Arabia are backing Al Nosra which is a local branch of Al Quaeda. And UK and particularly France with that idiot Laurent Fabius timidly backs them to please the Gulf states so they buy them weapons. Airplanes in particular. Against the advices of their own military. It is changing but slowly.

Also rotor ships.

But as far as i know such systems are experimental and used as a complement only.

The amount of energy stored this way is ridiculously low. It is a fun idea but the applications where it can be used are very limited. Like flywheels
I dunno...

Yep, the Lenin was the first propelled ship to use non-fossil fuels. Without resorting to massive batteries.

Plus there were other battery powered boats before the Chines one.
