  2. Re:Is there energy to be had here? on First Measurement of Distribution of Pressure Inside a Proton (phys.org) · · Score: 1

    If I had mod points, I would mod your response up because its thought provoking. It does however have the makings of an interesting debate.

    By definition - Fission: the action of dividing or splitting something into two or more parts. By saying "Fission implies splitting of parts that are already there." you are making an arbitrary decision on the meaning of fission. At best this is semantics and splitting hairs. Please provide a generally accepted reference that shows proof that fission only involves the separation of indivisible components.

    "Neutrons aren't made of protons and electrons" - I think you're trying to say that a proton is not a separate proton and electron somehow bound together and on that I agree. Your statement is misleading though because its like saying "omelettes aren't made of eggs and cheese". They are however typical decay products of a neutron. Its interesting to note that this process is reversible with the observation of electron capture.

    "Neutrons become protons and electrons (and antineutrinos) by converting a down quark to an up quark." I recommend you qualify that statement by adding: "It is generally accepted with the successful theory of the standard model that..." If I took the position that quarks are imaginary things that serve as an analogy, you would have a difficult time proving otherwise. Their existence is purely inferred by observations and whose existence is rooted in equations where the math works out. Don't get me wrong, the standard model is incredibly useful, but it is not unlike the Bohr model of electrons orbiting a nucleus the math works and its easy to draw, but that's not truly ho nature works. In any case we would just shift the argument above for a one that says down quarks decay into up quarks electrons and binding energy that is released in some form.

    Absolutely. Neutrons can decay to a Proton and Electron and extra energy. This is fission of a nuclear particle which I think is what you mean by Subnuclear fission.

    Based upon my experience - it uses a stunning amount of energy to mine an intangible thing. Vastly more than any other way to create any kid of currency. The algorithm is designed to be compute intensive and uses a ton of power. Two computers using a bit over 1000 watts each running for a month mining Litecoin with high end graphics cards caused my electric bill to double. That was years ago when it was much less compute intensive than it is today.

    From an ecological standpoint, this approach to currency is a colossal mistake. I cannot believe more people aren't complaining about this type of blockchain technology's impact on the environment.

  6. Re:These are business decisions on Tesla Rejected More Advanced Driver Monitoring Features On Its Cars, Says Report (theverge.com) · · Score: 1

    What house of cards? I've had my Model S for 5 years and it is by far the most reliable car I've ever owned. It is better than new with the relatively common and painless software improvements. People are amazed when I tell them its over 5 years old because it is still like new.

    What I see is a battle of hype vs. misinformation from large market forces who have a great deal to lose when everyone realizes that except for long trips, electric cars are superior in every respect.

    The fact is that the Tesla cars while not perfect are excellent products made by people who care. I cannot say that about the Ford, GM, Honda, Nissan and Toyota cars I've owned. Most of my conventional cars were designed to fall apart and then be replaced after 5 or 6 years. If success is measured by a company producing great product that stands the test of time than Tesla can't lose.

  10. Re:It's not frivolous. on Nikola (Motors) is Suing Tesla (engadget.com) · · Score: 2

    I don't agree. The Tesla vehicles have quite a bit of novel technology.

    To the best of my knowledge they were the first auto maker to mass market:
    + the combination of lithium ion batteries and supercapacitors for their energy storage strategy
    + rely heavily on frequent over the air software updates to effect continuous improvement
    + sell directly to consumers with a more eCommerce centric model
    + a business model that generates a demand for an all electric vehicle that far outstrips production capacity

    The list goes on and on.

    You don't have to be a fan boy to realize that anybody who thinks Tesla is not innovative is either ill informed or a misinformation spewing bot trying to protect the last gasp of the climate destructive fossil fuel industry.

    I beg to differ. The internal on CPU chip hardware for advanced vector extensions (AVX) executes many parallel fused multiply and divide instructions in one clock cycle. This is fundamental to critical machine learning algorithms. The underpinning of linear regression is y=mx+b and AVX is purpose built for this.

    One of the advantages to this approach is reducing the bottleneck of moving large amounts of data from the matrix math oriented machine learning system to a conventional procedural CPU.

    I think their stock price just dropped because the new tax plan drops electric car subsidies in addition to the production delays. If that tax plan passes, all electric cars will have more headwinds depressing sales.
