    And I thought the 9% just work alone

    Heading into a concrete wall is also deadly at high enough speed. And that is much easier to do, since walls don't move.

    What the hell

  4. The CO2 certificate trading in the EU should be able to finance this. It's also a good measure to see if it is cost-effective.
    Kinda strange that the US does not have emission trading, from what I read? I thought this idea was brought up by the Americans when the Kyoto protocol was negotiated.

  5. How can Bitcoin be efficient? Its security comes from the complexity of the calculations. This complexity translates directly into an insane power consumption at the miners. Due to how its security works the cost of this power consumption must must be a quite large fraction of the value of the transactions.
    This is just crazy. The base design of cryptocurrencies makes them an insane waste of electricity, therefore creating lots of environmental damage.

  6. Re:Same difference on Renewables Will Be World's Main Power Source By 2040, Says BP (cnbc.com) · · Score: 2

    Gas power plant construction is drastically shrinking worldwide. GE and Siemens are cutting lots of jobs because of that. The reason why coal and gas are collapsing are cheap solar cells. This summary here is just wrong on this.

  7. Re:I suspect that study could be called sexist on Women's Brains Are 'Four Years Younger' Than Men's, Study Finds (theguardian.com) · · Score: 1

    I would also draw the conclusion that the cognitive shape of men is developed as if they have 4 years more life experience than women.
    What are they analysing? Sounds to me as if they look at brain activity patterns. So women are just thinking a bit more like children.

  8. Which is not an option for deliveries

  9. Locl pollution has to be solved locally. CO2 is a global, long-term problem.
    In the EU the limits on local pollution are so low, it is completely harmless to healthy adults. The limits are set with elderly people, infants and asthmatics in mind. There is just some fight in Germany about that, because cars are banned from driving in some cities because of these limits.

    That's not any better with bitcoin though.
    The whole rising bitcoin value phase is just insane deflation.

  11. Re:Stainless "seems" like a bad idea on Elon Musk Explains Why He's Building 'Starship' Out of Stainless Steel (popularmechanics.com) · · Score: 1

    I wonder why it's relevant though how stable the starship is at cryogenic temperatures? It must be stable when taking off, but then it is not cold. And it must be stable i the later phase of reentry, but then it isn't cold either.
    Also the material cost shouldn't be that important, since they pan to reuse the ship.
    I would have though that Titanium is the material of choice for light-weight stable structures that have to withstand high temperatures. Also using different materials in different places might solve some issues.

  12. Re:They did this when they played the chess match on Can DeepMind's AI Really Beat Human Starcraft II Champions? (arstechnica.com) · · Score: 2

    Still I would conclude that Google's Deepmind only showed that it does not need an opening library.
    I would say a neural network just combines the advantages of a database and of calculating moves ahead. The weighting of different connections in a neural network seems pretty equivalent to me to storing a library of good and bad starting moves.
    Therefore it has pretty much a database function, and it is not surprising that it is superior to a software without one.

  13. Re:They did this when they played the chess match on Can DeepMind's AI Really Beat Human Starcraft II Champions? (arstechnica.com) · · Score: 1

    Still it sounds like they have chosen the battlefield that suits them best. E.g. maybe Deepmind is just better without the libraries because Stockfish was counting on these, and wasn't optimized to work without them?

    Wow, that's a pretty negative view after his all his successes.
    You know that some of his revolutionary ideas really worked out? Like landing rockets. Also his electric cars were far ahead of the competition for a while, although you could just attribute this to putting a large amount of money in it at the right time. Well, that's what he is really good at.

    But you claim that they are still building new plants. No, they finished last year. There is none under construction or planned, according to your article.

  17. Re:Energy budget? on Carbon Capture System Turns CO2 Into Electricity and Hydrogen Fuel (newatlas.com) · · Score: 5, Informative

    If you check how sodium is produced, you will see that it's done by electrolysis of NaCl. With that you can forget about the production of electricity in the process.
    The older production method is carbothermal reduction of sodium carbonate, which releases Carbon Monoxide, which will turn into CO2.

    I think the culprit are the insecticides used in agriculture. And this blame on others comes from their lobby.

    Ok thanks, that looks interesting. Well, probably the laser is ablating the skin and leather pretty slowly. i think it is impossible that it could be below the damage threshold of skin or leather, unless it is reflected near 100%. This also seems impossible though, since these intensities lead to multi photon absorption.
    My point is, it could be ok in a controlled environment, but such "dangerous" things won't get permission for consumer devices nowadays. Laser safety rules are pretty strict. The optical trapping might be low enough intensity though

    Oh, nevermind, they found a less crazy way :) They move a particle with an optical trap. This works with pretty low intensities, though the motion speed and acceleration of the particle are limited

    I think this could never be eye-safe, not even skin-safe.
    To render something in the air I guess the laser intensity must be so high that the air turns into plasma. If you put your finger where the spot is it will definitely get burned. And the light passing through the spot will damage the eye. I think that's impossible to avoid, unless maybe if the laser is focussed very strongly, meaning that it only works very close to the focussing lens.

  22. Yes, sounds like a joke if they want to install antivirus on it. Funny enough that this means they run Windows. It would also mean that they need to regularly install new virus signatures.
    What would signatures of known viruses be good for anyway? Their enemy is a bit more capable than script kiddies. They will certainly put the effort in to write a new virus to shut down missiles.

  23. So this was more of a rhetoric question, since it is already clear from the headline already that it doesn't.

  24. Well, the whole summary makes no sense of they consider alternatives. I have read such articles before, so there is nothing surprising in it off they make that mistake too.
    I do I know that research is done on replacing any rate element in solar cells, and none of them is an absolute obstacle. What is used is just determined by cost vs. benefit, do if an element becomes too Echobefund expensive it will be replaced. This is not as static as people from the outside see it.
    I have read the article now, and it shows no more awareness of this than the summary. I don't have time to read everything linked in it

  25. Does it talk about alternaives though?
    Indium is used in the transparent conductor Indium Tin Oxide. There are alternatives, such as Aluminium tin Oxide. Not as good, but it will be used if we are running out of Indium.
    And others already wrote that Neodymium is not needed for wind turbines. It is just a generator in there, it can be built in many different ways.
