    Well, despite the lower energy density, higher discharge rate is something LFP cells do better than lithium ions. In addition to having more cycles. For a jump aircraft yes it might take the clean sheets to actually fix this issue - the X-47 is going to test distributed electric propulsion for lowering the weight of the structure, reducing induced drag (wingtip vortices), while adhering to normal takeoff, landing, and stall speed requirements. For reducing weight, I'd even go so far that for a jump aircraft, the pilot doesn't need to be onboard the aircraft. The lift can be flown by AI, with a jump pilot on the ground in a DZ control room ready to take over if the AI needs assistance. Then, they won't need a bailout rig, you'll have room for one more revenue seat, but regulatory wise it could open a can of worms - I might start another topic on this if people are interested.

    For the Boeing 787 they couldn't solve that problem - they had to encase the lithium batteries in a heavy steel container to contain any potential fire. The NASA X-47 Maxwell uses LFP cells which are considered much less of a fire risk than lithium-ion. Elon Musk is also reported to be planning a change to LFP cells for Tesla cars as they're also a lot cheaper in addition to the increased fire safety, but their main issue is slightly lower energy density.

    No, that's not how it works. How much of the population gets infected depends on how low below 1.0 the R number is - if it's 0.1 or 0.05 then only a tiny fraction of the population will get infected before the virus dies out. Well that's an R number of 2.0 you're talking about, then yes of course it will quickly explode. South Korea had 9,000 people infected at one point, they've brought it down close to zero. The lockdowns, especially in Europe, caused the virus to almost die out by the summer - had they been in place longer, and effective measures like contact tracing set up when cases got low, the second wave wouldn't have happened. Viruses don't have a strategy, it's even quite debatable if they're alive in the first place. Again, I get your point, but don't let your feelings make decisions for you, use the numbers. What if the other vaccines are just as effective as hydroxychloroquine? Do you think the stockpiling of millions of doses of hydroxychloroquine was useful?

    There's this thing called the R-number, you know. Keep it below 1.0 long enough and the virus gets stopped - it won't run its course. It's basic mathematics. I think you're thinking with your heart rather than your head in this - you need to run the numbers! New Zealand, South Korea, Taiwan and half a dozen other countries pretty much got rid of Covid without a vaccine, by forcing the R-number to zero. It's not impossible. The vaccine will work only against Covid-19. But good, organised community responses will be able to fight ANY virus, especially those who don't have vaccines yet. And trust me, Covid-19 definitely won't be the last virus to cause havoc. The next one will come, not if, but WHEN.

    Apparently the media (AP) can call results, but only if Trump wins:
  8. olofscience
    Trump spouted lies, thousands of lies. Then people refuted the lies, including the media, who did not expect to have to do it in the beginning, but the lies were too many. Then you closed your eyes and still chose his side, and now you're shouting "censorship"? And yet you dove into it.

    That was pretty much the reason for all the violence before, and what the Good Friday Agreement was designed to stop. It's a truce between the Unionists (pro UK) and Republicans (wanting to join the Republic of Ireland). I'm sure you've heard of the IRA?
  10. olofscience
    Definitely. In this pandemic we've seen Scotland, NI and Wales go their own way and use their devolved powers to respond to the virus differently. People have watched as the First Ministers showed more competence than mini-Trump who kept doing U-turn after U-turn, protecting his friends and spending billions down the drain. He's even managed to piss off the north of england, with the mayor of Manchester being called the "King of the North" in his dispute against the government. The mayor of nearby Liverpool blames Boris' bungled response for the death of his brother due to covid-19. With the economy on its knees, the nail in the coffin will be a disastrous Brexit. With mini-Trump dancing on the cliff edge, it's only a matter of time.

    Now that Biden has won, I'm hoping that the shapeshifting creep isn't brave enough to forge ahead with breaking the Good Friday Agreement, but if he's stupid enough, he might still be able to earn the title The Last Prime Minister of the United Kingdom.
  12. olofscience
    Cause even Fox News has abandoned Trump? You've already decided that what is true is what you WANT to hear. Who's the snowflake?
  13. olofscience
    No, that's why you have the Copenhagen interpretation of the wavefunction.

    Calm down, tiger. Brent hasn't been making any claims of fraud, he hasn't been the one filing baseless lawsuits. The Trump camp did, and whatever you say to brent won't change their behaviour or cancel those lawsuits. No, people believe that baseless shit because they want to, not because the Trump camp filed lawsuits. My point is those lawsuits have been filed anyway, we can't do anything about that. What we CAN'T do is disrespect due process just because we don't like the other side.
  15. olofscience
    But didn't Trump stack the courts with conservative judges? If even they couldn't find any evidence of fraud, then that just shrinks the excuses Trump supporters have. Sure, they will continue to retreat to other excuses, but I want the island of their thinking and excuses to be as small as possible. Then maybe some of them will step out, realise they've been wrong and rejoin reality. And if not, they can stay in that little tiny island as long as they want.
  16. olofscience
    I actually agree with this! Going to be tedious, but sure bring them on. I don't think the Trump campaign have filed any further cases this week so far?
  17. olofscience
    They actually use numbers rather than "sure, super sure sure". Patience. I can't wait for it to arrive either but the numbers need to back it up.

    Now that Biden has won, this particular Ukrainian businessman is owning up since there probably won't be any US visa for him: https://www.thetimes.co.uk/edition/news/i-was-asked-to-lie-about-hunter-biden-admits-ukrainian-businessman-853krxgtz

    The money supply needs to account for value being created and destroyed all the time. If you grow $5 of tomatoes on ground that there wasn't anything before, you need to increase the money supply by $5 . If someone steps on those tomatoes making them worthless, you need to decrease the money supply by $5 to keep the value of money constant. Of course the Fed doesn't micromanage to this level, but they manage it since a small amount of inflation is much better than deflation (since deflation usually causes huge disruptions such as recessions and depressions). So the dollar cost of things doesn't matter as much as the REAL value of things - and automation and electrification does indeed drop the cost of things. Electrics have a high acquisition cost right now, but their lower running cost and maintenance costs are definitely much lower.

    What? Biden won BOTH the electoral college and the popular vote (by almost 5 million). So yes, get rid of the EC and Trump still loses.
  21. olofscience
    Even Fox News has called it. It's over.

    If you give that hypothetical vaccine with 2% kidney failure rate to 5 million people, then yes you'll have to choose between 100,000 people dying from covid and 100,000 people dying of kidney failure. The US has population of 350 million. Look, everyone, myself included, is absolutely desperate for a vaccine. But it still should be done properly and corners can't be cut. Edit: and your "2% possibly vs 100,000 positively" comparison isn't how probability works - the rate is already rolled into the total probability, so 2% will positively and definitely get those consequences (that the 2% probability defined in the first place).

    Markharju, desiring to see violence? I did NOT see that coming, no sir. <surprised_pikachu.jpg>

    Well with the huge shift to online logistics must be doing well. My company is noticing higher shipping charges though, ouch. But our supply chain is also pretty intact. Lockdown is pretty much over in China where we get lots of supplies though. My contact there was pretty surprised when I had to change our receiving address because of the lockdown. China, NZ, Australia, Taiwan, I feel so envious of those countries while we're having to lock down again in England once again. But we're led by a wannabe-trump so that's what you get I guess.
