  1. Re:Obligatory Reddit version on Can NASA Warm Cold Fusion? · · Score: 2

    All these reactions produce radiation that would have killed everyone around the plant. So unless you arm wave to claim that radiation is not magically produced in this device, your back to square one. Just like with other cold fusion claims.

    Also the eCat claims to fuse a proton with Nickel to produce copper. A quick check of the relevant tables gives us a "proton chain" where eventually a stable copper isotope is produced. However there are few unstable copper intermediates in between. These all decay via beta- and hence will yield a pair of 500keV gammas. A quick calculation for the claimed 1MW plant is tens of kW of gammas... without shielding....

    In God we trust. The rest of you show me the data.

    You know this is not really a new situation. The cost of reproducing books feel dramatically with the invention of the printing press and created copyright concerns back then. Its easier to copy a master piece than create one. etc. We are not really seeing a new thing with copies being much cheaper than the original. Hell even your cell phone cost way more to design than to manufacture... In other words, there are many things where the marginal cost of production is almost insignificant to the final cost of the product. Claiming that it cost nothing to copy is not a good argument that it should cost nothing.

    Of course i also agree with copyright... I even feel 20 years is too long. 10-15 feels about right.

    They interact mostly only via gravity, even with each other. They are so diffuse or dilute that yes they interact with earth via gravity but not in a currently detectable way, but we have detected it around clusters, in particular the bullet cluster.

    Dark matter does not interact electromagnetically. In other words is *can't* glow, it *can't* absorb light or microwaves or anything. We can see dark stuff, it blocks the CMB and other things. The fact that it does not interact except via gravity also means that is its very diffuse.

    Consider a non interacting particle falling from 1 light year out towards the sun. It falls right thought and out the other side and comes to a stand still 1 light year away. It will do this forever since its does not interact with anything that can slow it down. Now consider a say consider about 9x the mass of the sun of these particles, they will always occupy a massive volume and hence be very very diffuse... but in the large scale (galactic) are a large effect with their combined gravity. The are Dark in the sense that they *only* interact via gravity.

    Similar thing happened to me. I got a friend to ask him if he would bet on it. He took the bait, and offered a prize that i never claimed. There was 2 things you had to do, email anonymously! Seriously he didn't think you could do that. I emailed him as himself just for extra laughs. I will leave the second part out, but was a little harder, and perhaps not 100% legal. Either way it was almost as dumb and shows he had no idea what he was talking about.

    Slightly OT, but Aluminum is used because its a better conductor per unit weight than copper, and the cheaper price. Conductivity Al is pretty soft, but then the cores are high tensile steel and are the load bearing elements of over head wires. Due to the skin effect and steels poor conductivity, almost no current travels in the cores.

    Well they still aren't cheap and need quite a lot of technology such as quite high power drive electronics. Magnetic bearings are not simple either and typically have an active component to damp down vibrations and finally the composite rotors are not simple pieces of engineering either, since they need to spin close to structural limits, not distort too much and distort perfectly evenly, but dismantle in off design conditions in a way that is "safe" (ie in small fragments).

    One way to make them cheaper is to make them bigger and use cheaper simpler rotors that don't spin as fast. But then they start to get up to "septic tank" size for 1 week of power for a single home pretty quickly.

    I did think that something even bigger but cheap, could be installed with every wind turbine, since they already cost $3M a piece it should not add much over all (perhaps double the cost only?). This would mean that power connections can be rated closer to the average power rather than peak.

    Except you will need the reserve capacity since not every day is a mid summers sunny day. That is one of the costs of non demand power generation that is typically just ignored by proponents. And no "just use water pump storage" does not solve the problem, they are expensive and huge and can't be built where you need them. In fact you can't even build enough of them, and that is the currently cheapest option.
