Efficiency records involving perovskites are generally not that interesting without any longevity data. As far as I’m aware, the lifetime of current SotA perovskite solar cells is measured in weeks or months. That’s not commercially viable.
Not that efficiency research is completely useless, but the longevity is the real challenge that’s holding this up.
Reddit would become just another instance with no API control
Being that large of an instance gives a lot of api control all by itself. Theoretically Chrome is just another browser and member of WHATWG. in practice, if they implement something it immediately becomes a de facto standard. Reddit would be the same.
I wouldn’t bet on Huffman’s exit doing anything of consequence either. Reddit is now under the control of investors who want a return. One way or another, monetisation of users will increase.
But on a fundamental level, in the least instance admins have to be able to know who votes for our version of the system to even work compared to the competition.
Could you elaborate on this claim? Because I don’t really see why that would be true.
In this case, it redirects to Google’s general privacy policy that covers all their services. Anyway Google’s calculator stores a history of all the calculations you did in your account somewhere. So I guess it needs to have a policy stating what they do with that data.
The Chromecast is a small $35 dongle that goes behind your TV. This new thing is a whole $99 set-top box with an AI integration. They’re not really the same product.
Kinda but Thunderbird is community driven, and spun out into an independent subsidiary.
Laura Chambers, who stepped into an interim CEO role at Mozilla in February, says the company is reinvesting in Firefox after letting it languish in recent years,
It’s sort of amusing to me that Mozilla would let the Firefox browser languish. Is that not the raison d’etre of your entire organization? What are you doing with your time and effort if you are allowing your core product to languish? What would people say if Microsoft said “yeah, we’ve allowed windows to languish in recent years.” What an insane notion.
These are gonna be hella expensive for a while. If space is not a concern there’s much cheaper batteries out there. You don’t really need fast charging capabilities either.
You drive a full day with only one five minute stop? I think taking regular breaks is recommended when driving for long periods.
The sad truth is that there are overriding geopolitical strategic interests behind the US support of Israel. The American executive power recognizes this, so military support is not going to go away as long as those interests are a concern.
They may pay some lip service to the whole genocide thing, but this is ultimately realpolitik. Human lives do not matter when they are not American.
Hydrogen is a Japanese government strategic initiative, they want to be world leaders in the technology so they’re encouraging Japanese companies to invest. And giving out hella subsidies too.
It’s not intended to be a carbon sink. It’s essentially intended to be a more carbon efficient way of producing margarine without having to grow e.g. palm oil and destroy forests. They thought, instead of making plants do the work of turning water and CO2 into fats, let’s just do it in the lab.
The basic science could work, although it’s usually tough to beat “put seeds into ground and wait” on pure cost. However the fact that they compare this to butter makes me sceptical. Given how wasteful growing a whole cow is just to make some milk fat, it’s easy to look efficient compared to that. They would compare themselves to sustainably produced margarine if they were honest.
VW is good at making cars, but bad at software. They’ve had to delay the introduction of new models (Golf, ID.3) because of software issues. Rivian has sort of the opposite problem: their production lines sit still often because of problems in the supply chain.
Volkswagen has the expertise to solve Rivian’s production and supplier problems, and the cash they will need to survive and develop some cheaper models (the EV market is stagnating right now for a lack of budget options, and Rivian only sells trucks and SUVs). And they’re hoping Rivian software engineers can help them fix their software woes.
Yup, just like that
Apologies. I’m from a country where the meaning of the period and comma is reversed compared to the US, so I did it this way out of habit.
Honestly, I think it may be possible to build entire roads with enough crushed metal elements in the asphalt/concrete and a slight low power charge throughout the entire surface would be able to keep any vehicle battery at a steady charge.
You might be underestimating how much power a car consumes while driving. For example, a Tesla model 3 has an efficiency of about 130 Wh/km in mild weather at highway speeds. Assuming that on the highway you’ll travel 100 km/h, that means you’ll use 130*100 = 13.000 Wh/h, a constant power draw of 13kW. That’s enough to power perhaps 8-12 houses on average.
A km of road could have, let’s say, 200 cars on it (4 lanes, 20m per car). That means you’d need to pump about 2.6 megawatts of power into every kilometer of road to keep them all topped up.
EDIT: fucked up math
BOOM! EVs win!
Is this a real headline? Of a news article? Was that part really necessary?
And the upside down flying is simply due to gliding mechanics, no?
Not sure what you mean by this. But planes still generate lift when flying upside down. Wings with a symmetrical curve can also generate lift. Flat wings with no curve at all can also generate lift.
Pressure differences are definitely involved. That’s the only way air pushes against things, after all, so the fact that there is a lift force implies a pressure difference. However the cause of the pressure difference is rather complicated.
The problem isn’t even the hard drives, it’s how they are managing them. There’s not many digital data storage solutions around that you can dump into a closet for a few decades and then still read.
You have to regularly test your hard drives, so that when one fails you can take your other copy of the data and put it on a new drive.
