Re: Arrested for reactor building - What type?

<t>And my understanding is that he was boiling the brew in sulfuric acid. I have no doubt there was no significant nuclear reaction going on, just a boiling acid accident.<br/> <br/> The brew seems to have contained an alpha emitter (americium) and beryllium, so I suppose there were a few neutrons p...

Re: From Florida, hello from someone working to start a new research laboratory

<r>Greetings, Matthew,<br/> <br/> I actually ran into a reference to Spherelab II via <URL url="http://www.aresinstitute.org">www.aresinstitute.org</URL> while looking up STEM education in conjunction with "fusor" just today. I was pleased to see it and wondered if you had posted at fusor.net while ...

Science Fair Season book review

<r>I'm probably posting this in the wrong spot, so if someone with admin rights wants to move it, be my guest.<br/> <br/> Last night I was browsing a recent edition of Science News, and found I had an indirect contribution. <br/> <br/> The book reviews included a review of a new book called "Science...

Re: Can a house hold copper pipe hold a vacuum?

<t>Sure it will! <br/> <br/> Pulling a vacuum on copper is the best possible test of your "sweating" skills. Any tiny leak in the solder will show you your lack of skill. I have not tried lead-free solder with a vacuum yet, but silver soldering is used in vacuum work and ought to be slightly better ...

Promoting STEM

<r>My company is one of 18 to post short videos encouraging kids to get into STEM (Science, Technology, Engineering, and Math). They used the clip of our Damage Tolerant FA-18 along with some animation to show what fun work can be when you have a STEM background.<br/> <br/> The Amateur Fusion moveme...

Re: Good earth ground

<t>A good thought, that. My drain field is already in but I know where it is.<br/> <br/> The codes where mine is say it is three feet underground. My system uses four parallel 100 ft trenches, 10 ft apart, each 3' wide, and with a perforated pipe down the middle. That should be a pretty easy target ...

Re: Good earth ground

<t>That "bounce" problem is interesting. We used to have two buildings, a concrete "blockhouse" and a metal building. One day the metal building was hit by lightning. The entire structure evidently "bounced" at least several thousand volts. There was no electrical damage in that building.<br/> <br/>...

Re: Good earth ground

<t>The last time I looked at an electric code it was actually calling for two ten foot ground rods, some specified distance apart. There is a minimum spec for the ground conductor to the rods which is worth looking up. Probably 6 AWG at present.<br/> <br/> Be aware that the requirements for a buildi...

Yes, congratulations!.

I see a 2009 gallery at the popsci.com website, but not 2010. Do you have a link?

Re: "nuclear incident" in berlin, germany

<r>The company we took in primarily used iridium-192, which has a half-life of about 74 days. At least with that one, after a couple of years they're not so bad. The sources used for inspecting structures do initially have quite a punch, as they are typically used on relatively thick steel, but by t...
