Re: Good Afternoon from Central California

Building a demo fusor is not very difficult (compared to a real fusor) and can be fairly safe if one uses a minimum of caution and reads the FAQ's, and asks questions here when in doubt. A NST (see FAQ's for that) are fairly safe (but one can kill one's self if you are extremely foolish) and creatin...

Re: First Plasma

Any gauge that contaminates your system tells you nothing except how to waste your time and efforts. Throw that junk away. Also, those connections on the chamber (besides the acrylic window) are not suitable for any real vacuum system. Creating a vacuum has enough issues for a novice without using a...

Re: Regional Science Fair Success - but still a long way to go

Congratulations on your success. As you are starting to understand, one needs to be careful discussing issues about natural phenomenon's like solar flares. These are and have been extensively studied by astro-physicist and theoreticians for many decades. Your first duty is to read experts on the fie...

Re: Design Foundation?

Another Question: Could we collect the ejected electrons and use them in the energy as well? Not fully clear what you are getting at but excited electrons in a fusor are not useful nor available to do work. The issue is the electric field - that generates the force for the deuterium ions and disrup...

Re: Design Foundation?

As someone who has built both such devices, a fusor is far away easier. An accelerator requires very high voltages that are very difficult to achieve. A Van Da Graaff is not doable for most people (there are exceptions but I still have not seen a real working accelerator posted using a VDG.) I did b...

Re: New User

A few words to address (partly) some of your questions. Relative to radiation safety, x-rays are the only major concern. The level of danger is not a simple issue - depends on voltage used and chamber wall thickness and issues of viewing ports/geometry. Read the FAQ's and reference some peoples disc...

Re: High Vacuum Engineering Design, Analysis, and Build of a Small-Scale Multipurpose System

Outstanding work to date; I really look forward to your neutron detection system build - or will you just buy a turn key system?

Re: Reactor Update - 4/22/18

Very professional upgrades and setup; as a safety note: does the metal frames have proper independent grounds - also, did you ohm all equipment to grounds to verify that all have good connections? I, however, like a redundant ground for the main chamber - if that were ever to float, an extreme dange...
