element or compound in tree bark that it burns with too much ash

A Berkeley group is developing the use of a plant for Se decontamination of soil. It is in field testing. (I could probably find a ref if someone wants it.) Then there are the Ni accumulators, which have several percent Ni in their sap, nicely chelated (citrate, I think). bob |

A.P. writes: Bob, can you say anything theoretical about the periodic chart of chemical elements as to that of fire, burning and ash. Consider that the elements to making fire are oxygen, carbon which are far to the right of the chart in rows 4A, 6A and that potassium of ashes is in row 1A far to the left in the chart. So is there some chart relationship as to fire and burning and the ash remaining afterwards. Is the act of fire some sort of acid base reaction.

Description of Indicator Plants and Methods of Botanical Prospecting for Uranium Deposits on the Colorado Plateau. US Geological Survey Bulletin 1030-M. 1957. Well that is truly interesting to me. Could I possibly compress one of these high selenium content plants and use that substance electrically? That is, could it be carbonized (such as charcoal) and then further processed without special tools? The selenium rectifier was the first semi-conductor device ever created, not including detector diodes. It was invented in 1933 by C.E. Fitts, and was being built by Sylvania about 1935. If you remember tubes, RCA had the monopoly from 1919 until 1941. Sylvania was a competitor, but they built military stuff, and unlike the tubes built by RCA, Sylvania's were encased in metal, rather than glass. Please see: "Road to the Transistor" http://www.jmargolin.com/history/trans.htm Sylvania built a lot of heavy industrial and military components, and the invention of the selenium rectifier was a way to eliminate a (breakable) tube. They also produced the last tube built in the United States, in 1977. I like to think that if I suddenly found myself to be naked in the wilderness, that I would have the potential to make anything at all that we have now. Unfortunately, selenium is toxic, so the device would have to be well encased. Ah! How to make natural epoxy? More; how to draw wire from a stone? Michael |
