Re: Dr. Park to speak at UW-Madison
If a polywell ' s fusion is anuetronic what sort of radiation does it produce? What is the half life? Or is it only anuetronic when using boron?
Re: Dr. Park to speak at UW-Madison
Aneutronic is a misnomer. It is low neutronic. About 1,000 to 1,000,000 times less neutronic depending on the B11/H ratio (and that depends on the Deuterium in the Hydrogen).jgarry wrote:If a polywell ' s fusion is anuetronic what sort of radiation does it produce?

The half life depends on what absorbs the neutron.

The major neutron producing side reaction for pB11 involves a collision between a fusion product alpha and a boron ion. Relatively quick escape of fusion products suppresses this reaction.MSimon wrote:Aneutronic is a misnomer. It is low neutronic.

Re: Dr. Park to speak at UW-Madison
Thanks for the reply. Is there any other radiation produced? I gather there's nothing that needs to be stored for thousands of years.

Re: Dr. Park to speak at UW-Madison
It is my understanding most of the product will only need to be stored short term. Maybe hundreds of years for the bad stuff. A huge improvement.
I am not a nuclear physicist, but play one on the internet.
Re: Dr. Park to speak at UW-Madison
I gather the thing of interest in a polywell is the production of high energy ions/electrons. How are these harvested? It sounds as though there's no need for a process to transfer heat and produce steam or something of that nature, but instead somehow electricity is obtained directly?
Re: Dr. Park to speak at UW-Madison
The electrons are to be held at the center of the magrid (the "box" of coils) while the alpha particles are to be harvested by arrays of metal ribbons lining the vacuum chamber walls called the "Venetian Blinds"jgarry wrote:I gather the thing of interest in a polywell is the production of high energy ions/electrons.

Well, with the alphas exiting the magrid through perhaps as many as 16 cusps in a nigh-omnidirectional spray...MSimon wrote:Firing the alphas through a coil might be easier.zapkitty wrote:... alpha particles are to be harvested by arrays of metal ribbons lining the vacuum chamber walls called the "Venetian Blinds"

Wouldn't it be great if some clever engineering enabled the magrid to serve a dual purpose here?
Re: Dr. Park to speak at UW-Madison
Not required. Coils of wire are relatively cheap. It would however require pulsed operation. But that may already be inherent in the device.zapkitty wrote:Well, with the alphas exiting the magrid through perhaps as many as 16 cusps in a nigh-omnidirectional spray...MSimon wrote:Firing the alphas through a coil might be easier.zapkitty wrote:... alpha particles are to be harvested by arrays of metal ribbons lining the vacuum chamber walls called the "Venetian Blinds"

Go to aneutronics.org and download "Aneutronics: to Slow the Rising Tide". Turn to Chapter 2. Carefully study each graph in sequence. Read the Chapter.MSimon wrote:There really is no need to panic.

Ya know I object to this on the very first page:
1. natural gas (methane) is a greenhouse gas, 20 to 80 times worse than CO2; large amounts of methane escape to the atmosphere during fracking.
2. coal plants with CCS (carbon capture and storage) leak huge quantities of CO2,and the use of coal kills millions of people in many ways every year
Analysis: Solar activity & ocean cycles are the 2 primary drivers of climate, not CO2
Read the analysis - it is not very long.

I'm getting crotchety in my old age. I object to people who object to plant food. I like plants.
Do you have any idea what the minimum amount of plant food in the atmosphere should be?
