Hi All,

I may be very far off topic. Trying to find purity ie %  of Magnesium in fire starters. 

In Aussie land. the last thing we need are fire starters !!

What is the magnesium composition / % of various automotive components

A site which id rather long, do not dismiss immediately.

@ All:

I found this on the net today.

http://www.anodesystems.com/pro5.html

Look at this quote from the anode site:

"A 17 pound magnesium anode can produce 1 amp of d.c. current for 1 year; therefore, if it produced 1/10 amp, it would last 10 years compared to 3-1/2 years for a 5 pound anode. A 17 pound anode placed in 1,000 ohm-cm clay would generate 170 M.A. of current and would last only 6 years. If the clay's resistivity is 2,000 ohm-cm, it would last 11 years. In 10,000 ohm-cm dry sand, it would last 52 years. A normal current output is under 100 M.A. However, this engineer has seen the natural current output of a magnesium anode reach 200 milliamps (M.A.)"

Evidently these are used when installing underground tanks but check out that it gives 1 AMP!!  Even the 200 mA figure sounds good to me. 

I will go back and see if I can find any pricing on these.

@ IndianaBoys:

Thanks, I saw that when I went back.  I am still checking around and have found some even cheaper.  They make magnesium anodes for hot water heaters (rod shape) and they should not be all that much.  I wish I knew this a while ago. Thanks for posting it.

This might be a great step forward in upping our power.  That 1 amp output for a year quoted on the anodesystems site did not say anything about a cathode spaced away from the anode on the n/s meridian so, maybe we can get even more???  I need to check into this.

G'day everybody,

To make it easier for those of you who are following my current line of research (the Stubblefield series) I have just uploaded my posts on the subject onto my website. This way everything is presented as a total project in sequential form. I will keep it updated as the need arises.

any comments are appreciated
