ESA builds air-breathing engine that works in space The European Space Agency has hailed the successful test of an air-breathing engine that works in space. The engines don’t need the oxygen found in air to burn. Instead, as the ESA has explained here, the idea is to collect air, compress it, give it a charge and then squirt it out to provide thrust. The engine has no moving …
The email link for corrections? If you use webmail or don't have an email client set up for some other reason it is completely useless
If only computer came with the ability to copy a bit of text from one browser window to another eh? That would mean we could do a whole lot more!
There - can you see my level of sympathy? It's not only very, very small, it's also very, very, very far away...
> you missed the "Tips and corrections" link
You mean the mailto: link? If there was a proper webform that was quick and convenient, I'd happily use it. Having to disclose my email address or go through the faff of logging into a throwaway one to correct someone's spelling mistakes? I don't think so.
Sending email is DIFFICULT??? Methinks ElReg might be too advanced for you. Perhaps try another redtop?
And BTW, Mr/s AC, ElReg already has your email address. Remember, that one you used to sign up with? The one that all your posts are linked to? Hint: eyeball your posting history. Not all that anonymous, are you?
> Mr/s AC, ElReg already has your email address.
The throwaway email address that I used to sign up here like twenty years ago does not even point to an existing domain. I am not sure if it ever did.
Quite apart from the loss of privacy, I would hate to deal with all the spam that results when people give their actual email address(es) to world + dog.
So you admit you falsified your ElReg registration info? Are you certain you want to do that? After all, it's been your handle "for like 20 years" (yeah, sure, right). I'd hate to see you lose it.
You also admit that you use email addresses that are not yours? There's a word for that.
How on earth do you equate using a proper email address to register here with "giving your email addres(es) to world+dog"? Do you really think ElReg is likely to sell your address to spammers? Or are you so paranoid that not even your DearOldMum knows your email address? Because I guarantee that ElReg is a hell of a lot less likely to be compromised than she is. Kinda makes email pretty useless for you, no? So you may as well use the real thing, useless as it is ...
Your privacy in this context is totally meaningless outside your personal paranoia.
Do you really think ElReg is likely to sell your address to spammers
.. which they don't. Or, at least, I've never had any spam addressed to the variant I use for El Reg..

Just because you are paranoid doesn't mean they are not out to get you..

The tips and corrections link is a mailto: link, which isn't much help when you don't have an email client installed.
And I'll admit to being too lazy to go through the rigmarole of logging into webmail when I can just post it as a comment.
The reg would be better off making it a form that, it they really want an email, sends an email.
The reg would be better off making it a form that
.. can be abused by every spam engine out there?
I have one website that has a feedback form. Despite the fact that it goes no-where else other than webmaster@, it gets tons of autofilled spam.
It also regularly gets a whole SMTP conversation (albeit one-sided) where scum^W spammers are trying to use it as if it was an open relay..
The sort of complaints we'd have to get used to if Jacob Rees-Mogg was to become Prime Minister (please no), where tedious (Mogg like-minded) people get so wrapped up in minute detail that nothing ever gets done.
It's a great article, see it for what it is.
(You could be having a field day over at the Daily Mail. Maybe, head over there, they describe Scottish people as "English roses")
Elon Musk's plans for a low orbit, low latency cluster/network of satellites providing Internet capability, is looking rather more feasible and manageable. This would give those satellites a much longer working life.
Maybe he knew more than he was letting on when he announced it.
He's the third organisation with the idea. Work started already.
The problem is that while it solves the latency issue of Ka-Sat (with its 82 spots approx), it doesn't give very good capacity.
Good coverage doesn't mean good speed.
That's called an ion thruster. Lots of those have been used.
This uses the ambient "atmosphere" (although it's roughly < 1/32 Sea Level pressure).
This is (loosely) an "Ion ramjet" rather than an "Ion rocket"
So yes that is pretty impressive as it's one of the first (the first?) ever demonstrated.
JS19 suggested that the environment under discussion was "...roughly < 1/32 Sea Level pressure...".
At orbital velocity, roughly 1/32 Atmosphere would cause any spacecraft to be quickly incinerated. This is one reason why there are not very many satellites orbiting at 80,000 feet above the Earth.
Ooops.
Well that's what happens when you use the rule of thumb of air pressure halving every 5.6Km.
In fact https://www.avs.org/AVS/files/c7/c7edaedb-95b2-438f-adfb-36de54f87b9e.pdf
Suggests its more like 72 millionths of a Psi.
depends on how this tech scales but you could find more sats lasting longer in low orbit. More accurate GPS, sat phone prices (both handset amd air time) might drop to sane levels (imagine access outside everywhere in the world and pico cells for inside). Cube sats could be revolutionised.
