Not the parent, but I believe they were talking about LCOE, or total cost including building the plant and operating it. So that will be the cost of natural gas plus the rest amortized.
That's the thing we need. If your satellite is operating and in Low Earth Orbit, it is extremely easy to avoid a collision, even without any propulsion system.
If you are aware of the risk of collision a couple of days in advance, just changing your satellite orientation for a couple of orbit will retire the risk of collision.
You may want to perform in-orbit servicing, but that is more about increasing the longevity of your assets in orbit or increasing their capabilities via refueling/upgrading/repairing.

[...] in our test, the party political content chosen by the recommendation systems on Tik Tok and X was politically biased.
On TikTok, 78% (28/36) of this recommended party political content was supportive of AfD. On X, 64% (14/22) of such recommended party political content was supportive of AfD.
The picture on Instagram was very different. 96% of the content we were shown on Instagram came from one of the eight accounts we followed.
With personal photos, PDFs and everything, that's 3-4TB. With pure documents, that's still around 100-200GB.
The thing is, I don't know what I will need at a given time so I cannot just have a subset synced. Like when some friends I am visiting abroad wanted to have pictures of my house, or of an event we did with our children, now I can browse through them live.
> It can not be a matter of "data always available online", because you could solve this with a virtual online drive that can be browsed and/or synced with your work computer.
That's exactly my reason for using nextcloud and other apps like that though.
I want to be able to browse my own files from my phone or any other safe device, and that's what nextcloud offers. It is literally a "virtual online drive that can be browsed and/or synced" with any device, much like bewcloud.
I personally use nextcloud because I am using its other features as well, and there is no denying it suffers from being a jack of all trades, master of none, but having your data in the cloud, being able to access you admin paperwork, share data with your relatives or even random people, or manage a calendar amongst several people is a fairly frequent use case.
They can make SpaceX life hell through the ITU. Eventually SpaceX can only operate if they get the licences to operate, and if they bypass this, they would show that they have a disregard of RF regulations and this will be used against them the next time they need to get/renew a licence.
It would be useful for people who do not have a home charger, so that they understand if they can do a whole week with it. It is also useful for taxi drivers (though I would hope they do more than just reading a single number).
It is difficult to find a good solution for this, even providing 3 ranges (city, suburban, highway) has its limits and will confuse people.
No, they are saying that the nuclear drive shall be reserved to a shuttle that remains in space. At that point, it makes much more sense as you can really use the nuclear drive to its full capabilities.
> If we need the full performance advantage of nuclear propulsion, we should design a spaceship that is intended for it from the get-go. It never lands, only going from orbit to orbit, so there is no need for heat shielding, flaps, high thrust engines, thick steel structure or aerodynamic shaping requirements.
It will take some time to be more widespread, but I think this and small 7kW stations here and there (like the ones from Source London) charging will be the technical solution.
As for how this will be incentives, I don't expect to see much until ICE are banned. 65% to 75% of households in the UK have off-street parking, that's more than enough for charging providers to get established and have different types of cost effective chargers. Once ICE are banned, then there will probably be incentives to cover dead zones. Unfortunately, that's usually how it goes and people living there are usually getting things last, like for broadband, 5G.
It's a bit more complex than that unfortunately. Depending on how long you stay at high charge level it will negatively impact the battery life. So someone charging at 100% all the time but discharging quickly might see a better cycling count that someone charging at 90% but staying there almost all the time.
I have a heat pump in such a house, even worse actually since it is a semi-detached. I did not need to do any extra work, and it works fine. My savings are not great, but that is also mostly because I don't have a hot water tank so I still need gas for my hot water. We just replaced 3 radiators, one of which is actually still permanently shut and I am still doubtful about the need for the other twos.
For the walls, it can become quite expensive to insulate it. But at least for the wooden floor, you have a cheap option: lay a new laminate flooring with proper underlay. It will cost typically less than £1000, you'll avoid damaging your wooden flooring, and also improve the thermal confort by removing the air leaks and insulating more.
Yes. CCS2 has not technically won yet as being the default port for all EVs in Europe, but any other option would have to have significant advantages over CCS2 to win, features that a potential CCS3 version would not be able to support.
> In that world, Tesla would have had to switch their cars over to CCS eventually and retrofit their existing chargers to CCS, and people who bought Teslas with the proprietary plug have a terrible UX of needing adapters everywhere.
It should be noted that in any case Tesla will have to support CCS, though in its CCS2 version. It is the de facto standard in Europe and is in the process of making their chargers in Europe fully compatible since the M3 comes with CCS2 by default here. And it is unlikely to change any time soon, CHAdeMO is dying here and all the other networks are using CCS2 (which seems to be much better than CCS1 if I trust the complaints about CCS1 I read on HN).
You'll need to have a good source on that because the majority of the latest satellites are using at least AES128 or better AES256 for this kind of stuff. Granted, a few of the implementations I have seen are a bit exotic and probably somewhat vulnerable, and the key management can be quite manual, but we are not at the middle school teenagers level anymore.
And I doubt very much that Starlink or OneWeb (OW is using AES256) satellites are that easy to hack, and they by themselves are most of the satellites.
Many satellites are also able to monitor contacts made from the ground and if someone is able to gain access to the communication stream, they'll quickly (within 10min) have to learn how to hack the onboard software to reset these monitors.
They hacked OPS-SAT which was an experimental satellite by ESA to test different ways of operating a satellite. The very purpose of this satellite was to be a test bench for this kind of things.
Gas as in petroleum. In the UK, this was caused initially by a constraint on having enough drivers for the trucks, which lead into a few local shortages. The fear came into that and people rushed to fill their tank. The system being not sized for this, this ended up creating actual shortage with a positive feedback loop.
Similar issue in France: strikes were happening leading to local constraints, which was then amplified by people rushing to fill their tanks. In both cases, the situation comes back to normal after a few weeks.
This is the toilet paper shortage, or the bank run, all over again.
Or it could be a PCM pin-puller system: basically paraffin is heated and while it liquifies, it will slightly expand and push a pin that will trigger the release.
