The panel will filter the incoming light; these displays emit light. With high transparency panels you could get something that works well when there is an external light source, although with worse color distorsion.
I make a distinction between positive/inclusive or negative/exclusive identity. While I certainly condone the statement "I'm not a murderer", I try to define myself in terms like "I value life". This gets tougher when certain positive constructs come with a lot of negative connotations. We can try to reclaim those words, emphasize that being a nerd is about devouring information and not about despising social contact, but sometimes its a lost cause and all we can do is come up with a new word. Another way of thinking of it is to be the union of identities, not the intersection. This heuristic can fail in many ways, but it's served me well so far.
You would find it very hard, if not impossible, to run an ICE car at 40% efficient for normal driving. The same can not be said for a coal plant. So if the coal plant averages 35% and the ICE car averages 25%, that leaves some room for a coal-driven electric car to be more efficient. The conversion from grid power to mechanical power only needs to be over 70% efficient. If anything, that sounds easy to beat. Any counters?
What about refinement costs to turn oil into gasoline in the first place? That takes energy as well, and creates pollution. So we have a loss before we even get to the ICE.
I we say all three of: charging, motor controller and motor are about 90% efficient, that's already 72% efficiency from grid power to mechanical. So maybe not that easy.
While a 90% efficient motor is quite good, a 90% controller and a 90% charger is not. I would expect them to be closer to 95%. But I have to back down from easy, according to [1], some Tesla owners charge their vehicles at 80% efficiency and not the ideal 92-98%. I imagined that would be a problem at those energy levels, apparently not! Anyhow, there is nothing inherently worse about fueling a central ICE to pump out electricity to EVs than directly fueling an ICE car. Larger ICEs tend to be more efficient, especially so for diesels. If you add the savings by the regenerative charging enabled by electric motors, it becomes even more favorable to electrify cars. We need a lot of batteries though!
There's around twice as many european countries with a lower percentage of homelessness than the US on that list compared to those with higher. Though, those where to a larger degree more populated. You could probably cut it how you want it, but framing it as Europe having lower homelessness is too simplistic and that was my main point.
While Switzerland is one of the countries with lower amount of homeless people, most of EU is much lower than - say - the UK (in Brexit times this might be interesting), but this kind of numbers may well (and actually are) very debatable because of different ways the "homelessness" is calculated.
Also you have to consider how in continental Europe there is an ethnic group, the Romanis (more commonly called gypsies) that traditionally move across the various countries and that may be counted one way (homeless) or the other (or not counted at all).
And comparng a single smallish country with the whole US makes little sense anyway, usually homelessness (like in this case talking of Seattle) is concentrated in very limited areas (usually in or around large cities) where the rest of the country is unaffected.
I didn't find anything about the story of the lawyer when searching. Could you tell me where to look? The story fits my preconceived notions too well to not question it...
Thank you for forcing me to look for reference. It turns out that I got the story a wrong in pretty much all the details, but - I'd argue - correct in the conclusion. The event did not happen a month or two ago, that was apparently the point at which I heard about it. And it didn't involve Afghani refuges. It involved Syrian refuges, and it happened in 2015.
The lawyer, Viktor Banke, raised around 15,000 SEK (slightly less than $2000) to help Syrian refugees who were living temporarily in the Mosque at Medborgarplatsen in central Stockholm. He had raised this money with the promise that they'd be given to the people who were running the shelters, to help them finance the operation. When he arrives, he meets a Syrian woman with children who, while travelling from Syria through Europe, had been registered as a refugee in Hungary. Since EU policy at the time was (and maybe still is?) that refugees should be handled by the first country they register in, it looked very likely that she and her children would be sent back to Hungary. Notably in this story is that at the time Hungary was considered a "less attractive" country for refugees than Sweden. Viktor then decides to hand the raised money (not a huge sum of money, but still) to this woman, rather than to the people operating the shelter.
I don't have any international references for this at all - apparently Viktor wrote about it in his new book Andrum, in which he discusses Swedish politics w/r to the refugee situation in Europe (I have not read the book).
I don't think the trouble of scavenging, testing and grouping the laptop batteries is worth it. The cheapest quality cells I've found costs around 210 euro for 1 kwh. To reach the same capacity you would need ~17 healthy laptop batteries @ 60wh.
With all the added work, buying just one type of cell seems way better. But really, why not buy deep cycle lead acids and an auto-watering system? No hype!
Mindfield, the new series by vsauce, tackled this in its first episode, which recently became free to watch.
It was an interesting watch, although I couldn't really take the experiment seriously after the segment with the former inmate who had spent way more time confined in a cell with even less stimulation than the one Michael was about to enter.
Anyhow, prolonged isolation(>3 days, maybe less) and willful disruption of circadian rhythms should definitely be considered torture.
Also, doing this to people who will reenter society is just so shortsighted and dumb, regardless of the total lack of morality.
Sure it had an impact on design, but given a couple of years, they would have gotten there(hardware-wise).
