NASA to Investigate Hydrinos
An Anonymous Coward writes "A new NASA program might once and for all settle the "hydrino" question. The concept of the hydrino -- hydrogen shrunk below its normal state with the resulting release of extreme ultraviolet light -- has been derided by the physics establishment and surprisingly embraced by many engineers and people with deep pockets. Slashdot hashed the hydrino pretty vigorously in December 1999. Now NASA is funding independent research into making a rocket from this novel idea. If it works, we could be seeing a sea change in physics. If it fails, hydrinos might finally just float away. There's an active study group of several hundred users (including some prominent scientists) devoted to debating the possible existence of hydrinos. In many ways it sprang from slashdot."
The concept of the hydrino -- hydrogen shrunk below its normal state
Sounds like a hydrogen atom took a dip in a cold swimming pool...
Oh wait...
My first thought was the Schrodinger equation - it can be solved for Hydrogen.
Question 1 : Are hydrinos possible according to the Schrodinger equation?
Question 2 : If not, what changes to Schrodinger are needed to explain hydrinos and are these changes consistent with the rest of physics?
(Question 0 : Or am I smoking crack again?)
The only hits on Schrodinger and Hydrino were from the blacklight people and they seemed to skirt around the question.
"...In many ways it sprang from slashdot." Because copying a story makes you responsible for the discovery of a theory that breaks modern physics.
Just because NASA gives money to somebody to research something doesn't mean it's not a crackpot idea. They set up a project to try to verify Podkletnov's horse manure, too, didn't they?
We don't have a state-run media we have a media-run state.
Strange how we've never spotted the emission line corresponding to transitions to this below-ground-state in the hydrogen spectrum, isn't it?
Strange how a bunch of perpetual motion merchants wave Quantum Mechanics around the place for the explanation of how their gadget works. Sometimes. When no actual physicists are looking, but often when potential investors are around.
Strange how many cranks the NASA Breakthrough Physics Program gives respectability to. NASA's least-funded irrelevant sideshow picks up every nut that comes along, investigates their claim, and nothing comes of it. Nut carries on with career saying 'Yep, NASA were interested, and then they covered it up! Big oil interests leaning on the gub'mint, see, don't care for the little guy, with one of these you could be rich!'
I suppose NASA have to be doing something Trekkish - the man in the street expects them to be working towards the Starship Enterprise, after all. Just a shame about the fallout.
Personally, I'm backing Schrodinger to win this one :-)
Real Daleks don't climb stairs - they level the building.
A simple way to look at the hydrogen atom from quantum theory point of view is this:
Quantum mechanics says, that in order to confine anything (here electron), you need to give momentum which increases as you shrink confinement radius. Who supplies the necessary momentum to confine electron in an atom? It is electrical attraction force between proton and electron. However, the enery needed for momentum increases as square of 1/r, while the amount of enery you can generate from electrical attraction only increases as 1/r. There is a balance at some value of r, and that is the radius of hydrogen atom.
Now, if you want to shrink hydrogen radius further, you would need to SUPPLY more enery to it, rather than being able to get from it. What complex quantum mechanics equation says is that there is no stable radius below ground level. But even if there is a stable radius below ground level, you still cannot get enery by compressing hydrogen atom. It is like a spring. If it is stretched, then you can retrieve energy by slowly retracting it. But that doesn't mean you can get energy out by compressing an unstretched string.
If you only take the electro-magnetic force into account, then it's impossible. If you introduce some other force, it's possible. Some atoms, such as Kr-81 can actually partly "collapse" - it's called "electron capture" and is caused by the Weak Force. This is not possible for hydrogen, because the resulting neutron would be heavier that the original atom. We don't know any such force that would result in a lower energetic state for hydrogen.
The BlackLight Rocket link on Wired isn't slashdotted, it's just wrong. Here's the real page and a much more informative writeup of the whole concept at space.com, April 2000 , where Wired seems to have gotten most of their story. Sigh.
