  1. Gallium, indium, and tantalum? on Interviews: Ask CMI Director Alex King About Rare Earth Mineral Supplies · · Score: 1

    Gallium, indium, and tantalum are not rare earths. They are all much to rare for that.

  2. What carbon would you like to tax?

    All fossil carbon.

    The electricity people use? Or just some portion based on percentage of generation?

    Only the part that comes from fossil carbon.

    Or do you include everyone with wood-burning fireplaces? Do you buy wood pellet stoves for everyone?

    No. Whether they are allowed is a separate issue.

    More for coal? Less for nuclear?

    More tax on coal and less tax on nuclear, yes.

    Who is poor? What about the middle class - sounds like AGAIN they get to pay the VAST MAJORITY, when they have already been squeezed and squeezed and have lost the value of their wages for 40 YEARS and now you want to take MORE?? Not only that, you want them to pay more for power AND more for power for the POOR that they are already helping support???

    The middle class should, on average, break even. We need to discourage the use of fossil carbon while doing as little harm to the economy as possible. Cap-and-trade is worse.

  3. No, I want people who use more energy to pay more for the environmental consequences. The fact that the rich use more on average means that some poor may gain. I'm ok with that.

  4. What a surprise (not) on Ferguson No-Fly Zone Revealed As Anti-Media Tactic · · Score: 5, Insightful

    Somebody should go to jail over this.

    It won't happen, though.

  5. I don't know what the answer is, but adding more taxes to everything, and raising prices on all of it, doesn't seem like a workable plan.

    I think a carbon tax is the only workable plan. If you rebate the tax on a per capita basis the poor should end up with more.

    Finding the political will to do this may be difficult.

  6. Re: I'm sick of this shit. on Imagining the Future History of Climate Change · · Score: 1

    It seems to me they are more interested in whining about the problem than doing the hard work of finding a solution.

    Finding a solution is easy. In fact, there are several of them. Getting everybody follow one is hard, and many don't see the need for any of them.

  7. Re:Fission = bad, but not super-bad on Fusion and Fission/LFTR: Let's Do Both, Smartly · · Score: 1

    As I recall even thorium will only provide several centuries at 100%, though we could increase that by an order of magnitude by developing seawater extraction technology.

    You don't get thorium from seawater; there isn't enough there. Uranium can be recovered from the ocean, and there is enough thorium on land to last nearly forever.

  8. Re:Nuclear binding energy WAS:Hoax on Independent Researchers Test Rossi's Alleged Cold Fusion Device For 32 Days · · Score: 1

    Yes, nickel is the most stable isotope, but hydrogen is not. There is quite a bit of energy released by combining a proton with any stable isotope of nickel.

    I am not saying that Rossi isn't a fraud. He surely is. There are multiple problems with his demonstration, including the total lack of radiation, the conversion of almost all the nickel to nickel-62, the suspect calorimetry, the disappearance of one isotope of Be and the creation of another. But a lack of energy from combining nickel and hydrogen isn't one of them.

  9. Re:In highschool on Exxon and Russian Operation Discovers Oil Field Larger Than the Gulf of Mexico · · Score: 2

    The Russian find is 300 or so metres down and thus it is easy oil.

    In the Kara Sea? That is a much rougher place to work than in the Gulf of Mexico. I'm sure they will eventually manage, but I wouldn't call it easy.

  10. Re:No warning? on Update: At Least 31 People Feared Dead After Japan Volcano Erupts · · Score: 1

    Pretty smart. There were Italian scientists convicted of not warning about an earthquake.

  11. Re:I Voted For Kodos. on US Revamping Its Nuclear Arsenal · · Score: 1

    I voted for Kang.

    Really, he was on the ballot.

  12. Re:Maybe 40k on Is the Tesla Model 3 Actually Going To Cost $50,000? · · Score: 1

    In their conference call Tesla stated their intention was to continue using cylindrical cells, but that the size would be increased by about 30%. Sorry, I didn't save the link.

  13. Re:Golden opportunity missed... on Wave Power Fails To Live Up To Promise · · Score: 2

    The problem with wave farms is that they harness the gravitational power between Earth and the Moon.

    No, that would be tidal power. The wave energy comes mostly from the wind. The main side effect that occurs to me would be less coastal erosion.

  14. Re:Maybe 40k on Is the Tesla Model 3 Actually Going To Cost $50,000? · · Score: 1

    Nobody is using the size of cells that Tesla claims to be interested in producing. If they get cheap enough companies might design some products around them, but, for example, they will be too fat for a cell phone.

    Of course Tesla might make other sizes, but I doubt they will be in any hurry to do that.

  15. Re:Three times less = negative number! on Universal Big Bang Lithium Deficit Confirmed · · Score: 1

    Heh. I had no idea that was a real word when I wrote it.

    No, it's an idiotism. But dictionaries are happy to reflect that usage nowadays.

  17. Re:Container ships on To Really Cut Emissions, We Need Electric Buses, Not Just Electric Cars · · Score: 1

    Listing two obvious fallacies doesn't prove the initial statement is one, although at best it could only be true of sulfur based pollution. Of course, sulfur dioxide helps keep the planet cool anyhow, so maybe we shouldn't count it if it is released in the open ocean.

  18. Buy a better bus! on To Really Cut Emissions, We Need Electric Buses, Not Just Electric Cars · · Score: 4, Informative

    A 30 mile range? What kind junk are the buying?

    A BYD electric bus has a nominal range of 155 miles. It sounds much more reasonable to me.

    This is the New York Times.

    No, it is the Los Angeles Times. There are many Times in the world, the summary should reflect that.

  20. Re:Don't they use a lot of water on Reno Selected For Tesla Motors Battery Factory · · Score: 1

    They need Electrolytes...

    The electrolytes used in lithium ion batteries don't use water. Water is unstable at those voltages.

    Of course, the factory must use some water, if only for the employees drinking. I don't know how much, though. Perhaps it is worth mentioning that there appears to be a small river near the site.

  21. CDR yes, SRM no on Climate Scientist Pioneer Talks About the Furture of Geoengineering · · Score: 1

    I don't see any problems with carbon dioxide removal, aside from potential local environmental problems. The methods include reforestation, adding iron to the ocean and grinding up serpentine.

    Solar radiation management, like adding sulfates to the air, has lots of global environmental effects, and it doesn't do anything about acidification of the oceans.

    It's best to consider these separately.

  22. Re:Can we get a tape drive to back this up? on Seagate Ships First 8 Terabyte Hard Drive · · Score: 1

    Tapes has a crapload of drawbacks, write speed, read speed, the fact it's sequential (random access is painful) but it remains popular because you can drop it, smash it, submerge and then freeze it and all you have to do is roll the tape into a new case.

    Maybe they have fixed it, but I heard some old stories about dropping tapes corrupting them.

  23. Re:Economic risk on How Argonne National Lab Will Make Electric Cars Cheaper · · Score: 1

    The lithium in a modern battery is not aqueous, which is the default in your table. What the result would be in a modern electrolyte, I don't know.

  24. Re:Economic risk on How Argonne National Lab Will Make Electric Cars Cheaper · · Score: 1

    Nicely written post, but you don't know what you're talking about.

    Hydrogen is not the strongest reducing agent amount the stable elements. If you go by electronegativity it is cesium. Cesium is rather heavy, though.

    Lithium would make a very good cathode (if we could just control the dendrites), but it's not what lithium-ion batteries use. Transition metal compounds are far from ideal for cathodes, but they have the advantage that we can make them work pretty well.

    Lithium-sulfur is potentially the next battery after lithium-ion, if only we can make them last long enough.

    This asteroid is only around 1 km in diameter. An impact would be distinctly annoying, but civilization, and most people, should survive.
