I don't follow(?)

The production of iron is supposedly the last possible fusion reaction and the fate of some very long-lived stellar entities.

https://en.wikipedia.org/wiki/Iron_star

 

Amazing fact: the Sun's fusion only produces around 100 W/m^3. About the same power as an incandescent light bulb (per m^3).

I may prefer a peltier like element for cold fusion and quantum tunneling in my pocket than a hot fusion light bulb as big as a sun then :--p

 

The production of iron is supposedly the last possible fusion reaction.

It's obviously not the last, otherwise we wouldn't have any elements above that.
It's just the last that generates energy when it is formed by fusion.
Above that, energy is absorbed when the heavier elements are created by fusion, much if it during the high energy explosion of stars, like a super nova.
That's why fission of the heavy elements like uranium and plutonium generate energy.

 

It's just the last that generates energy when it is formed by fusion.

Correction: it is the first that consumes energy when formed by fusion.

 

https://en.wikipedia.org/wiki/R-process

In 2017, entirely new astronomical data about the r-process was discovered in data about the merger of two neutron stars. Using the gravitational wave data captured in GW170817 to identify the location of the merger, several teams[24][25][26] observed and studied optical data of the merger, finding spectroscopic evidence of r-process material thrown off by the merging neutron stars. The bulk of this material seems to consist of two types: hot blue masses of highly radioactive r-process matter of lower-mass-range heavy nuclei (A < 140 such as strontium)[27] and cooler red masses of higher mass-number r-process nuclei (A > 140) rich in actinides (such as uranium, thorium, and californium). When released from the huge internal pressure of the neutron star, these ejecta expand and form seed heavy nuclei that rapidly capture free neutrons, and radiate detected optical light for about a week. Such duration of luminosity would not be possible without heating by internal radioactive decay, which is provided by r-process nuclei near their waiting points. Two distinct mass regions (A < 140 and A > 140) for the r-process yields have been known since the first time dependent calculations of the r-process.[10] Because of these spectroscopic features it has been argued that such nucleosynthesis in the Milky Way has been primarily ejecta from neutron-star mergers rather than from supernovae.[3]

These results offer a new possibility for clarifying six decades of uncertainty over the site of origin of r-process nuclei. Confirming relevance to the r-process is that it is radiogenic power from radioactive decay of r-process nuclei that maintains the visibility of these spun off r-process fragments. Otherwise they would dim quickly. Such alternative sites were first seriously proposed in 1974[28] as decompressing neutron star matter. It was proposed such matter is ejected from neutron stars merging with black holes in compact binaries. In 1989[29] (and 1999[30]) this scenario was extended to binary neutron star mergers (a binary star system of two neutron stars that collide). After preliminary identification of these sites,[31] the scenario was confirmed in GW170817. Current astrophysical models suggest that a single neutron star merger event may have generated between 3 and 13 Earth masses of gold.[32]

I'd like one of those gold planets.

My mistake.

 

There must be an approach for changing in q level of nucleus in room temp or abs zero in order to make use of fusion energy sensible ,or so called cold fusion.maybe the same as junctions used in transistors,peltiers,etc for electron's q level?!

"May the Force be with you"

I have no idea what you are saying(?).

Conservation of energy. What you need is a Zero Point Module.

You could have at least chosen a pic with Rodney McKay and a "zed" pee em. He's Canadian, you know.

I didn't like his character on the show.

 

AFAIK,the main issue for cold fusion is raising probability of quantum tunneling for reaction,so it'd happen by the same analogy for electrons by making junctions with different materials like metals.BTW that zero point sci fi module is more like to lollypops :--E

Right, sort of like how the only obstacle to intergalactic space travel is the lack of a practical warp drive....

We can't even get hot fusion to produce a surplus of energy. So what makes you think that we could possibly supplant the Sun's constant supply of gravitationally-induced pressure in some tabletop setup at near room temperature?

It just boggles my mind how people entertain these kinds of dubious ideas on a daily basis. Face it, none of the above will ever happen because each and every one of them defies the intrinsic laws of physics! It is as simple as that.

 

Please allow to note that heavy water and superheavy water both are still the water and nothing else.

By the way, very intriguing ideas about this topic may be found at anoutronic fusion project of crossfirefusion.com. However at least one scientific mistake in their project I have found, noted to them, but they reacted with nothing - thus, probably the sci crap. But interesting anyway.

maybe because the magic is what expected both from material science and newly quantum science rather than classic physics,
as the Invention of transistor using semiconductors that was so like a magic for vacum tube lamp era.
and also, that's why they knew earlier alchemists as magicians.
