The Thomas Edison EEStor-like Battery Mystery

Previously, I wrote about a curious quote attributed to the inventor Thomas Edison and recorded in a June 11, 1911
New York Times article in which Edison claims to have "perfected a battery which can be recharged in three or four minutes and which will run fifty or sixty miles without being recharged. "

What happened to this battery? Were the claims ever confirmed? With the GM-Volt having an initial target range of 40 miles and requiring relatively much longer charge times, one has to wonder where did this Edison technology go off the track?

To find out, an EEStory reader contacted the Director and General Editor of the Thomas A. Edison Papers, Dr. Paul Israel. Dr. Israel is a leading scholar in Thomas Edison studies and he was kind enough to respond to our query concerning specifically, Edison's claims to have a quick charge battery capability.

According to Dr. Israel there has not yet been any "detailed research on Edison's storage battery." Israel pointed out that the records for Edison's efforts in this endevour "have been microfilmed but not yet digitized. There is limited secondary literature on the battery and as far as I know none has tested this claim." He recommended this 1913 article in the Transactions of the American Electrochemical Society. Via a phone interview, Dr. Israel pointed out that two researchers have referenced Edison's battery in their modern day narratives. The first is Edwin Black's Internal Combusion, a pulitzer nominated conspiracy theorist's dream come true about Oil dependency. (BTW, although I say that in an amusing way, you'll quickly notice Black as someone with enormous credibility. ) It's not unimportant to speculate about the significance of the fire that destroyed Edison's battery labs in 1914 as Black does in his I have not read yet. The second reference Israel provided is Rich Schallenberg's 1982 book, Bottled Energy: Electrical Engineering and The Evolution of Chemical Energy Storage. I have read neither book but both look interesting. Israel was also asked whether or not Edison was ever prone to exaggeration of claims. He pointed out that in disputed matters, if one can establish that he was correctly quoted, typically his claims were bore out with scientific proof, ie, he was not a boaster.

Major Nanosolar News scheduled for Sept 9, 2009 or The September 9, 2009 Announcement Page

Followers of the EEStory know I'm not entirely one dimensional. I do track other technologies and one of them is solar printing mystery company Nanosolar. As I do periodically, I shot a note to Martin Roscheisen this morning requesting an interview. Within 4 minutes, I had a reply saying he would allow the interview in the 2nd half of September and that there is

"some significant news upcoming on 9/9."

Indeed, the Nanosolar website has been updated to reflect an upcoming announcement.

So, let me summarize the announcements on September 9, 2009 or 2009 September 9 if you are in Australia or other places. Apple is announcing something on 9/9. Nanosolar is announcing something on 9/9. The Beatles are announcing something on 9/9 Anyone else? EEStor? 9/9? :-) (relax, it's not a tease. just a question)

Note: Dick Weir and Martin Roscheisen both once worked at Xerox PARC. I queried PARC media relations about this and was told, "we reached out to several of our veteran scientists in our hardware research organizations, but none of them remembers either Richard Weir or Martin Roscheisen." It's interesting to me that both now seem poised to produce important technological breakthroughs using printing technology.
