Claim: cold fusion may have been verified by third-party researchers. I’ll believe it when I see it. Just posting as an item of interest for now. But oh my, if this ever turns out to be for real, it changes everything — and not just in tech or power generation.
(H/Ts: MJR and MtK)
ADDED: Sigh. It’s possible both of these might turn out to be scams. Per Sam in Oregon, here’s the latest on the Anonabox.
Already got a reality check on the cold-fusion device below.
ADDED: A comment by a friend who works in the power-generation field:
I downloaded and read the paper on the cold fusion device, called E-Cat.
Disclosure: I would like for this to be true. It would improve the health and wellbeing of mankind at least as much as the mastery of fire.
Rossi has been making these claims for years. One of the common elements in all of his experiments is that he uses complex means to measure the energy.
This paper is no different. They have to estimate the energy losses for no fewer than 3 different physical effects. One of those, radiation, accounts for more than 100% of the observed “excess” heat.
That’s a red flag right there. A competent analysis would have predicted how the heat would manifest itself: so much to radiation, so much to convection, so much to conduction. Then they could have checked their results against this prediction.
But they didn’t do that. They didn’t even test their “control” at the same power and temperature levels. Another red flag.
Radiation is a very difficult way to measure energy production. The power goes as the temperature to the 4th power, so a 5% error in temperature gives a 22% error in power. Then the alumina they used has a big change in emissivity as a function of temperature, and the temperature of the tube is far from uniform.
Bottom line; the most likely explanation for the “excess heat” is a sum of small errors in the measurements.
There are also claims of isotopic shifts, but those are tough to measure with the equipment they used. The absence of any radiation means we would have to throw out most of what we know about nuclear physics.
I’m not at all against throwing out theories that don’t work. The problem is that nuclear physics works pretty darned well. Nuclear reactors, nuclear weapons, nuclear medicine, solar physics, cosmography, all of these things require detailed calculations of nuclear reactions and rates, and all of them get answers that are pretty much exactly right. There are always questions at the edges, such as solar neutrinos, but there isn’t any suggestion that the physics is wrong.
The process of throwing out older theories for better ones always follows the same path. The old theories work well enough for a while. Eventually we push the edges enough that the calculations start producing answers that don’t match what we see. A fair amount of data is collected showing that we have a problem. Then some smart person proposes a new theory that explains all of the old stuff AND all of the new stuff.
That isn’t happening here. There isn’t a collection of hints that we have a problem in nuclear physics. Quite the opposite. The further we push, the more confirmations we get.
So I don’t buy the claims of isotopic shifts.
Then there is the question of the complex experimental setup.
The excess power they claim is equivalent to nearly 2,000 watts of excess heat being produced. That’s a lot. If there really was that much heat, it would be easy to measure directly, without the trouble and errors of trying to calculate power from radiation.
Just one idea, to show how straightforward this could be.
Immerse the thing in wax, or lead, or salt. Make the container big enough that it is clearly impossible to melt the contents from the electrical input power alone. Then run it until the container is full of melted whatever. That’s proof. No fancy measurements required. A bit of engineering math in advance, build 2 or 3 to run controls before and after, and you have a bullet-proof demo.
This isn’t a bullet-proof demo. It’s not even a demo. I don’t know if Rossi is running an elaborate con game or if he believes this stuff. It doesn’t matter; I’m pretty sure there is nothing here. I’d be more than happy to be proved wrong.
An elderly woman got the last word after locking a police officer in her basement, and later suing the police.
Venus Green, who was 87 when she was handcuffed, roughed up and injured by police, will receive $95,000 as part of a settlement with Baltimore City. The city chose to settle the case instead of taking a chance in front of a jury.
“We thought we would have a difficult time in front of a city jury, or any jury,” Baltimore City solicitor George Nilson said.
Green was so put out by what police officers did, the city said she locked one of them in her basement.
Read more at the link. It just gets better. Yes, cops treated Venus Green like cr*p. But she never bent an inch, and clearly she won this case because city officials were not about to go to court and say their armed agents brutalized an 87-year-old retired schoolteacher because they “felt threatened” by her. Even though she is obviously one tough — and well-informed — lady.
Not long ago, I rolled my eyes and said the tiny-house movement had jumped the shark. Then this morning, friend G. sent me to this site. And this 192-square-foot house, the Axia.
While there’s a suspicious dearth of info (the link to TechDwell’s pdf brochure is 404), it’s a for-real thing. Portland, Oregon, is building a village of these for the homeless.
If they’re as easy to build (and unbuild) as they say … well, that’s remarkable. On price, on tech, on a number of measures, they’d beat the usual overpriced tiny house hands down. (That is, if somebody doesn’t get carried away and order all their yuppified options.)
Yes, yes, go ahead and tell me you can build something like this yourself out of old pallets, cardboard boxes, and strapping tape for much less than TechDwell’s basic price. That’s true. Joel’s Secret Lair is similar and cost less. But the tech on this is intriguing, as is the ability to tear it down and move it. Also, you can add your own options (solar, rainwater catchment, etc.) for less than they cost from TechDwell.
The look reminds me a bit of the UnitOne cabin. But if the TechDwell Axia is all it appears to be, I’d rather have an Axia.
Gads, what a great artist’s studio. Or guest house. Or pool house. Or vacation cabin.
Antigunners have become particularly bloodthirsty lately — to the point where its becoming alarming. About one in 20 of their tweets and blog comments seem to demand that some non-violent gun owner be killed. Others crow with glee over murders committed using guns.
The world has been too much with me, late and soon. That whole JPFO business was hard and bitter. The aftermath’s been no picnic, either. Even though you and some renewed work for the Backwoods Home print ‘zine have risen to help me through the money part of that, the emotional part is just … whammo.
But I’m not here to talk about that. I’m here to forge a plan. You can probably help. You always do.
(I’d leave a comment over at Borepatch’s site, but far as I can see, you have to use an “official” ID with Google or some other outfit. Not doing that and can’t see why an increasing number of sites demand it.)
Furrydoc asked in comments the other day, “Where’s the CDC?” (in fighting Ebola in the U.S.) Rhetorical question, of course. She knows quite well where the CDC is: giving bland assurances to the media about being just right up there on top of Ebola while primarily occupying itself with profitable and political mission creep. These days it’s focused on “epidemics” such as obesity and “gun violence.”
Ron Fournier, at the National Journal says the scariest thing about Ebola isn’t the disease but our growing lack of trust in government and other institutions.
Gads, it was 80 degrees yesterday. Eighty in October in the Great NorthWET. There are entire summers when we don’t see 80. I don’t think I’ve ever seen it this warm this late in this corner of the world.
Supposed to be “only” in the 70s for the rest of this week. Oh, poor us.
With construction catastrophes keeping the house in chaos, I’ve been trying to de-clutter to help deal with the fact that every time I organize stuff in one area, it immediately has to be moved back out because … oh, the roof falls in or somesuch.
So I’m whipping myself into a crusade to de-stuff.
